Jerome Gambit: Cliff Hardy Revealed!

I recently received an email from "Cliff Hardy" that contained a significant "reveal" as well as an entertaining Jerome Gambit game. The following notes are his, except for some minor ones by me, in blue. Enjoy!

An epiphany on Epiphany OR Batman* vs the "Visual Bat"

Hi Rick,

I had an epiphany on Epiphany!

The epiphany was to play the Jerome Gambit on the 6th of January, the date of Epiphany - the day of the year dedicated to the Christian feast celebrating the manifestation of the divine nature of Jesus to the Gentiles, as represented by the Wise Men.

I don't really mind whether I am referred to as my Bruce Wayne-like name of Kevin Sheldrick or my Batman-like alter ego "Cliff Hardy", since I now have played a Jerome Gambit in a tournament game and have been told by the arbiters that all games from this tournament will be published on the internetski at some point - in other words, my secret identity is out!

All analysis below is with Stockfish.

Sheldrick, Kevin - Bhat, Vishal
Australian Open, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5

I now spent about a minute on my fourth move and found it extraordinarily difficult to play my planned 4.Bxf7+. This hesitation largely being due to a battle raging inside of me of conflicting thoughts of doubt and fear of playing the Jerome, giving rise to a soliloquy, going something like this:

Me (to my brain): "This is one of the most prestigious chess tournaments in Australia - don't take on f7!"

4.Bxf7+

My brain (to me): "DON'T TELL ME WHAT TO DO!"

4...Kxf7 5.Nxe5+

Surprisingly, this move was, by now, very easy for me to physically play. I guess it's kind of like trying to go into a cold swimming pool. At first you may be terrified to even dip your toe into it, but if you can put aside the fear and just jump in, you can then adjust to it rather easily.

5...Nxe5 6.Qh5+

Fellow participant, Tony Fereday, in the post-mortem exclaimed, around this point in the game, "I wonder what he was thinking!", in reference to my opponent.

6...Ng6?!

Better 6...Ke6

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6


This position is as old - fittingly - as Charlick - Mann, correspondence, Australia, 1881 (1-0, 72). The Database has 163 games with the position, with White scoring 70%. Mind you, beside this one, only one other game (by Guido de Bouver of Flanders, Belgium) is an over-the-board encounter. - Rick 


10.O-O Ng4 

Better 10...Kf7

11.Qg3 h5?! 

Better 11...Nf6 

12.h3?! 

12.d4 is best, which would allow the bishop on c1 to cover f4 and prevent the knight on g6 from going there, where it may assist black to launch a kingside attack.

12...h4 13.Qb3

Having made queen moves for almost half of the total moves played (6 out of 13 moves), it was apparent that I had been violating a few established chess opening principles so far in the game.

13...Nf4!

A brilliant sacrifice!

An improvement over the play of the only other game in The Database to reach this position: 13...N4e5 14.f4 Nc6 15.Nc3 Qf6 16.d3 Qd4+ 17.Kh1 Nf8 18.Nd5 Kd8 Black resigned, perrypawnpusher - Riversider, FICS, 2010 - Rick 

14.hxg4??

Oops! The cautious 14.Kh1! may help white to hope to defend against the vicious black assault on the white king.

14...h3?

A miscalculation in a bafflingly complex position - 14...Qg5! actually leads to a thumping black kingside attack e.g. 15.f3 h3 16.g3 h2+ 17.Kh1 Ne2

15.g3 h2+ 16.Kh1 Bxg4 17.gxf4



White has defended well, and is a pawn and a piece ahead. Things are still scary for him, but Black has only one move to keep the advantage. - Rick

17...Bh3?!

An inaccuracy - 17...Qh4! 18.f3 Bh3 

18.Re1 Qh4 19.Qg3 Qh5 20.d4 Black resigned



Eerily, as I went strolling in the moonlight one night (I think it
was the night immediately after I had just played this game), a large visual bat (or flying fox, as they are referred to in Brisbane) emerged from a nearby tree above my head and flew away, silhouetted magestically against the night sky but, oddly, I didn't fully comprehend the ominousness of that until days
later.

The final position is still quite complicated, but White should be okay. If need be, he can return some material to settle things down further (i.e. Re3 with the idea of sacrificing the exchange on h3 while exchanging Queens) - and he always has his "Jerome pawns"! Black may have realized at this point that he could save his energy for the next round. 

However dubious the honor, Kevin seems to have grasped the title of "strongest player to use the Jerome Gambit in serious over-the-board play". Well done! - Rick

The Stuff of Nightmares


Bill Wall's latest Jerome Gambit is the stuff of nightmares - for his opponent. Toward the end of the game, checkmate threats abound. I have given in the notes some that Bill has mentioned, but you might want to test yourself and see what you can find. Take a look.

Wall, Bill - Tsyalex
PlayChess.com, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 

So far, a routine Jerome Gambit position, appearing 221 times in The Database, starting with Charlick - Mann, corr, 1881 (1-0, 72).

9...Qf6 10.O-O

An alternate is 10.d3, from Wall,B - G3LC, PlayChess.com, 2011, which I have mentioned before, but not given the moves to, so I will do so now: 10...Nh6 11.Nc3 Ng4 12.Qg3 h5 13.h4 Rf8 14.Nd5 Qxf2+ 15.Qxf2 Nxf2 16.Rf1 Ng4 17.Nxc7+ Kd7 18.Nxa8 Rxf1+ 19.Kxf1 b6 20.Bg5 Bb7 21.Nxb6+ axb6 22.a4 Black resigned

10...Bd7 11.d4 N8e7 12.f4 Qh4 13.c4 Rf8 



A (pawn) storm is coming, and Black begins to think about shelter for his King (by castling-by-hand).

14.f5 Nh8 15.b4 Nf7

More prudent might have been 15... Kf7.

16.a4

You have to know that this is going to end poorly for Black, even with his lead in development. It reminds me of "Gimme Shelter" by the Rolling Stones:

Oh, a storm is threat'ning
My very life today
If I don't get some shelter
Oh yeah, I'm gonna fade away

16...Rh8 17.Nc3 c6 18.c5 Kd8 



Maybe the King will be safer on the Queenside?! I don't think so.

Bill gives a couple of alternatives: 18...dxc5 19.bxc5; and 18...d5 19.Rf4 Qh6 20.exd5

19. cxd6 Nxd6 20. Qd3 Kc7 21.Bf4 g5 



Black works on his counter-attack, but it does not distract Bill.

22.Bxd6+ Kxd6 23.d5 cxd5 24.f6 Ng6

No 24...Nc6, as Bill points out: 25.Nb5+ Ke5 (25...Ke6 26.Qxd5#) 26.Qxd5 checkmate. 

25. Nb5+ Bxb5 

Avoiding Bill's 25...Kc6 26.Qxd5+ Kb6 27.Qc5+ Ka6 28.Nc7 checkmate. 

26.Qxd5+ Kc7 27.axb5 Rad8 



28.Qc5+ Kb8

Bill: 28...Kd7 29.Rad1+ Ke6 30.Qc4+ Ke5 31.Rf5 checkmate. 

29.Qxa7+ Kc8

Or the gruesome line Bill shared: 29...Kc7 30.b6+ Kd7 31.Qa4+ Ke6 32.Qb3+ Ke5 33.Ra5+ Kxe4 34.Qc4+ Ke3 35.Ra3+ Kd2 36.Qa2 checkmate. 

30.Qa8+ Kc7 31.Rac1+  Kd6

31...Kb6 32.Qa5 checkmate
31...Kd7 32.Rcd1+ Ke6 33.Qa2+ Ke5 34.Rf5+ Kxe4 35.Qe6+ Ne5 36.Qxe5 checkmate 

32.Rcd1+ Ke5

32...Ke6 33.Qa2+ Ke5 34.Rf5+ Kxe4 35.Qe6+ Ne5 36.Qxe5 checkmate
32...Kc7 33.b6+ Kxb6 (33...Kc6 34.Qa4+ Kxb6 35.Qa5+
Kc6 36.Qc5#) 34.Qa5+ Kc6 35.Qc5 checkmate 

33.Qa1+ Kxe4

33...Ke6 34.Qa2+ Ke5 35.Rf5+ Kxe4 36.Qe6+ Ne5 37.Qxe5 checkmate 

34.Qb1+ Ke3 35.Rf3+Ke2 36.Qc2+ Black resigned

The Classics II (a first look)



As mentioned in the last post, I have suggested that those who play, and those who face, the Jerome Gambit, would benefit from becoming familiar with "the classics" of that line.

That got me thinking: What would those classics be?

Here are the additional games from a preliminary sketch.

6. Charlick - Mann, correspondence, Australia, 1881

The Australian player Charlick, who had already played an "Evans-Jerome Gambit" against Holloway in 1877, won a long correspondence game with the Jerome Gambit against John Mann in 1881. Again, an interesting game, and another example of the Gambit's spread around the world.

7. Jerome - S.A. Charles, correspondence, 1881

As I noted in "The Jerome Gambit Gemeinde (early)"

S. A. Charles, a member of the Cincinnati (Ohio, USA) Chess Club, wrote opening analyses, first for the Cincinnati Commercial Gazette, then later for the Pittsburgh Telegraph. It is in the latter paper that in 1881 he presented his examination of the Jerome Gambit. That year he also played an incomplete Jerome Gambit correspondence match with Alonzo Jerome.

None of the games were completed before Jerome withdrew, because of "business engagements". This match has been given scant coverage in the blog. The situation will be rectified later this year.

8. Amateur - Blackburne, London, 1885

The best-known Jerome Gambit game (even if Blackburne got the year wrong in his book), a crushing win by Black. Later analysis showed how White could get the advantage. Even later analysis showed how the game could have ended in a tense draw.

9. Sorensen, S.A. -X, Denmark, 1888

This game, the first that I have been able to find with the "pie in the face" defense, also celebrates Lt. Sorensen, who, in the May 1877 issue of Nordisk Skaktidende, wrote a very influential article on the Jerome Gambit, which was translated and republished widely.

10. Tonetti - Ruggieri, Rome, 1863

The King-hunt in this game makes the Jerome Gambit almost look like a legitimate opening. Almost.

Blunder Blunders

When you have an opponent named "blunder", as Bill Wall does in the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, you can always hope that there might be some errors across the board that will help you out.

billwall - blunder2
Chess.com, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6


7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6


10.d4

Following in the footsteps of Charlick - Mann, correspondence, 1881 (1-0, 72).

10...b6 11.0-0 Bb7 12.f3 Kf7


13.Qb3+ Ke7 14.Qa3 Re8 15.e5 Nd7 16.Bg5+ Nf6 17.exf6+ gxf6


White has recovered his sacrificed piece and is a pawn to the good.

18.Re1+ Kf7 19.Qb3+ d5 20.Be3 Qd6 21.Nc3 Re7


22.Ne4 Qe6 23.Nc5 bxc5 24.Qxb7 Rae8 25.dxc5 c6 26.Qb4 Qf5


White is ahead a couple of pawns. If the players move to the endgame, the win is there, providing that the clock does not intervene. (Of course, familiarity with the Jerome Gambit often grants a time advantage.)

27.Qd2 Ne5 28.Bd4 Nc4 29.Rxe7+ Rxe7 30.Qd3 Qxd3 31.cxd3 Ne5 32.Bxe5 fxe5

33.Kf2 Rb7 34.b3 Rb5 35.Rc1 Ra5 36.a4 Ke6


37.Ke3 d4+ 38.Ke4 h6 39.f4 exf4 40.Kxf4 Kd5


41.b4 Rxa4 42.Re1 Rxb4 43.Re5 checkmate

Better isn't good enough


White starts out in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) with what can objectively be called "a lost game."

Fortunately, most club level chess games hardly proceed along "objective" lines.

Still, my opponent's sudden resignation – when I figured that he had solved the opening and was looking forward to some decent counter-play – came as a bit of a mystery to me.

Perhaps Jerome Gambit Gemeinde member Pete Banks was playing the wise detective when he suggested that some defenders never quite get over the "shock and awe" of the Jerome Gambit!

perrypawnpusher - GabrielChime
blitz 12 0, FICS, 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6



A good defense, one of a number of refutations to the Jerome Gambit.

7.Qd5+

The "nudge".

7...Ke8 8.Qxc5 d6 9.Qe3



So far we are moving along well-travelled lines – I have over 70 games with this position in my database, starting with Charlick - Mann, correspondence, 1881: 9...Nf6 10.d4 Qe7 11.0-0 Ng4 12.Qe2 Qh4 13.h3 Nf6 14.f4 Nh5 15.Qf2 Qxf2+ 16.Rxf2 Rf8 17.f5 Ne7 18.c4 c6 19.g4 Nf6 20.Nc3 d5 21.e5 Nd7 22.cxd5 Nxd5 23.Ne4 N7b6 24.b3 a5 25.e6 h6 26.Bb2 Ke7 27.Re1 Ra7 28.Nc5 Na8 29.Nd3 b5 30.Ne5 Kd6 31.Rc1 Ra6 32.Rc5 Bb7 33.Rfc2 Rc8 34.Bc1 a4 35.b4 a3 36.Bd2 Nab6 37.Be1 Na4 38.Bg3 Ke7 39.Nd7 Nxc5 40.dxc5 Rg8 41.Bd6+ Ke8 42.Rd2 Ra4 43.Rxd5 cxd5 44.f6 gxf6 45.Nxf6+ Kd8 46.e7+ Kc8 47.Nxg8 Bc6 48.Nf6 Rxb4 49.e8Q+ Bxe8 50.Nxe8 Rb1+ 51.Kf2 Rb2+ 52.Kf3 Rxa2 53.Nc7 b4 54.Nxd5 b3 55.c6 Rc2 56.Bxa3 Ra2 57.Bd6 Rc2 58.Be5 b2 59.Nb6+ Kd8 60.c7+ Rxc7 61.Bxb2 Rc5 62.Bd4 Rb5 63.Nc4 Ke7 64.h4 Ke6 65.Ke4 Rb1 66.Ne3 Kf7 67.h5 Kg8 68.Nf5 Kh7 69.Be3 Re1 70.Nxh6 Rxe3+ 71.Kxe3 Kxh6 72.Kf4 Black resigned

9...Ne5 

This is new to me. Maybe Black is trying to provoke my pawns?

10.f4

A little bit better might have been 10.d4.

10...Ng4 11.Qg3


I've had problems with "Wild Horses" a number of times in the past.

11...g6 12.d4

If those "Jerome pawns" look eggshell-brittle, I agree. The simple 12.0-0 was better.  

12...Qe7


Black begins to pressure the center, although 12...N8f6 might have been a better start. 

13.Nc3 Bd7 14.0-0 N4f6



I think that Black is holding his own (in part because he has not been developed enough to benefit from advancing his pawns), although after the game Rybka surprisingly suggested that Black should castle-by-hand on the Queenside: 14...Kd8 15.h3 N4f6 16.e5 Nh5 17.Qd3 Kc8 18.Bd2 Kb8 with a small edge to White.

15.e5 Nh5 16.Qf2


Better was16.Qf3. That "horse" was really throwing me. 

16...Bf5 17.exd6

This cannot be right: White throws away his large pawn center for a chance to make a check along the e-file. Rybka rates the resulting position as roughly even, but the "Jerome pawns" are much more effective as a unit, not split to make pawn majorities on each side.

17...Qxd6


18.Be3 Kd7 19.Rae1 Rd8 20.h3 Ngf6



Stronger was the move that Black probably originally intended, 20...Kc8.

21.g4 Black resigned

Yes, Black will have to return his extra piece, but in doing so he will probably receive open lines to attack White's King. At the end of the game, Black still has an edge, so my opponent's resignation surprised me.

King in Peril: Comment & Reply


From the comment to "King in Peril", which we repeat, along with answers...

"blackburne" said...
That one was a real battle. Interesting feature that the Black King gets back to his starting square after moving 12 times in the 26 moves! Is this a record? :)

The latest a Black King ever returned "home" in a regular Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game according to my database was move 58 in HIARCS 11.1 UCI - Rybka 2.3.1 32-bit 2008:1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 7.0–0 Nf6 8.dxe5 Ng4 9.Qf3+ Ke8 10.Bf4 Rf8 11.Bg3 Rxf3 12.Bxh4 Rf7 13.Bg3 Bd4 14.Nc3 Kf8 15.Nb5 Bxe5 16.Bxe5 Nxe5 17.Nxc7 Rb8 18.Nb5 b6 19.a4 Bb7 20.Nd6 Rf4 21.f3 Ke7 22.Rfd1 Kf6 23.b4 Kg5 24.a5 b5 25.Nxb7 Rxb7 26.Rd5 Kf6 27.a6 Rb6 28.Ra5 Rc6 29.Raxb5 d6 30.Rb7 Rxa6 31.b5 Ra1+ 32.Kf2 Ke6 33.Rxg7 Ra2 34.Ke3 Rh4 35.Rc7 Rxh2 36.f4 Ra3+ 37.c3 Nf7 38.Rf5 Nh6 39.Rf8 d5 40.e5 Ng4+ 41.Kf3 Nxe5+ 42.fxe5 Kxe5 43.Re8+ Kf5 44.Rd8 Ke5 45.Rc5 Ra2 46.Rdxd5+ Ke6 47.Re5+ Kf6 48.Rf5+ Ke6 49.Rce5+ Kd6 50.c4 Kc7 51.c5 Rhxg2 52.Rf7+ Kd8 53.Rxh7 Rgb2 54.Rg5 Rf2+ 55.Ke4 Rfe2+ 56.Kd5 Ra1 57.Kc6 Rae1 58.Rd5+ Ke8 59.Rdd7 Rf2 60.Kc7 Rf7 61.Rhxf7 a5 62.Rh7 Re7 63.Rhxe7+ Kf8 64.Kd6 a4 65.Rd8#.

I apologize, Jerome Gambit

One of the "benefits" of playing an off-beat opening like the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is that it has a built-in excuse for any loss: Of course I would have crushed him if I had been playing the Catalan...

Sometimes, though, even a disreputable opening like the Jerome – given enough cooperation by the opponent, of course – delivers a game that is quite playable, if not downright winable; and at that point, success or failure depends upon the player, not the opening. For the following game, I have to say: I apologize, Jerome Gambit...

perrypawnpusher - peroneal

Worth mentioning here is the game perrypawnpusher - hogmaster, chessworld, 2008 which is referred to in the note after move 10: 7...Kf8 8.Qxc5+ d6 9.Qe3 Nf6 10.0-0 b6 11.f4 Bb7 12.d3 Qe7 13.Nc3 Re8 14.Bd2 h6 15.h3 Qd7 16.Qg3 Ne7 17.e5 Nfg8 18.Rae1 Nf5 19.Qf2 Nge7 20.g4 g6 21.gxf5 gxf5 22.Re3 Rg8+ 23.Rg3 Kf7 24.Ne2 h5 25.Kh2 Rg6 26.Rfg1 Reg8 27.Nd4 dxe5 28.Rxg6 exd4 29.Rxg8 Nxg8 30.Qg3 Ne7 31.Qg7+ Ke6 32.Re1+ Kd6 33.Qe5+ Kc6 34.Qxe7 Qxe7 35.Rxe7 Kd6 36.Re5 Bc8 37.Kg3 Black resigned

9.Qe3 Nf6

Okay, I've been here before. This is my 6th game (up until now 3-1-1) with this position which was first seen, according to my database, in Charlick - Mann, correspondence 1881 (1-0, 71).

10.0-0 Bd7
A new move, with the idea of putting the Bishop on the a8-h1 diagonal, to pressure the e4 pawn. Other players, like hogmaster and Lark (above) have fianchettoed the Bishop at b7.

11.f4 Qe7 12.Nc3 Bc6 13.f5 Ne5 14.d4 Nc4

This kind of Knight attack on the Queen has happened a lot recently: see my games against DysonLin, episodeninetynine, Joejox and Lark.

15.Qd3

Where should the Queen go? Probably 15.Qe2 was a bit better. Proper positioning of the heavy pieces behind the "Jerome pawn" center will be an important test of the middlegame play – a test that I barely passed, with a "D".

15...Bb5 16.b3
Shoot. Me. Now.

Just like in my previous game, my opponent hangs a piece – and I miss it!

16...Ne3 17.Qxb5+ c6 18.Qd3 Nxf1 19.Kxf1 Rd8

White has two pawns for the exchange. Considering Black's King stuck in the center of the board, White has to have the advantage.

20.Bg5 Rf8 21.Qe3

In this position Fritz8 prefers 21.Re1, if only to answer 21...h6 with the surprising 22.Nd5 – after 22...cxd5 23.e5 dxe5 24.dxe5 hxg5 25.exf6 Rxf7 26.Rxe7+ Kxe7 White should have the advantage. I think 21.Re1 is good for calmer lines, too.

21...h6 22.Bh4 Qd7
It might have been time to put the King on that square, instead, and continue with him to c8 – castling-by-hand on the Queenside.

23.Kg1 Rc8 24.e5
Breaking in the center – probably too early. White's Rook could have gone to f1 or e1 first.

24...Nd5

After 24...dxe5 25.dxe5 Ng4 26.Qxa7 White would be better – for example, after 26...Rxf5 27.Rd1 followed by Nc3-e4 – but things would be messy; and the result would be better than after the text.

25.Nxd5 cxd5 26.exd6+ Kf7

What now?

White should be winning, and there should be some kind of "killer" move here – but I couldn't find it during the game.

Fritz 8 suggests 27.Be7! Then, if 27...Rfe8, White calmly plays 28.Re1 and his threat to infiltrate with the Queen forces Black to liquidate to a lost ending: 28...Rxe7 29.Qxe7+ Qxe7 30.Rxe7+ Kf6 31.Rxb7. Totally beyond my calculation at the time, as well, was if Black played the odd 27...Ke8 (Fritz 8's second choice) then White has 28.f6. All a bit too beyond me.

My move leads to an equal game.

27.Qe6+ Qxe6 28.fxe6+ Kxe6 29.Re1+ Kxd6

Wait a minute! With 29...Kd7 Black probably keeps the game a draw. The text move returns a favor.

30.Be7+ Kd7 31.Bxf8 Rxf8

All Rook endgames are drawn, right? Actually, I thought I had good chances to win this one.

32.c3 Rc8 33.Re3 Kd6 34.Kf2 a6 35.Ke2 b6 36.Kd3 g6 37.c4 dxc4+ 38.bxc4 Rf8
So far, so good. My extra pawn is protected and passed.

39.d5 Rf2 40.Re2

White's job is simplified if he can exchange Rooks.

40...Rxe2 41.Kxe2 b5

Black's last gasp.

I looked at 42.cxb5 Kxd5 43.bxa6 and even though Black can catch the forward White a-pawn, there's still the other a-pawn to be distracted by, while White's King feasts on the Kingside pawns... With only that amount of thought, I played

42.cxb5

only to see instead
42...axb5

Oooops...

The game is now drawn. The winning move, of course, was 42.Kd3.

43.Kd3 Kxd5 44.a3 Kc5 45.Kc3 g5 46.g4 Kb6 47.Kb4 Kc6 48.h3 Kb6 49.Kb3 Kc5 50.Kc3 Kb6 51.Kb4 Kc6 52.Kb3 Kb6 53.Kb4 Kc6 54.Kb3 Kc5 55.Kc3 Kb6 56.Kb4 Kc6 Game drawn by repetition


Nice work, peroneal!

Another game like my last two, and the Jerome Gambit Gemeinde might suspend my membership!
