Jerome Gambit: Tumblr?

I recently discovered "A  Jerome  Gambit  miniature" on tumblr.com, of all places, at "Coach Tortise's Adventures in Chess". Apparently the game was played via iPhone, at the Chess.com website. 

The Jerome Gambit. It's everywhere you want to play chess - apparently.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf6 7.f4 Qe7 8.Qf5 checkmate

And that's that... Nice work, Coach.

(I was surprised that, according to The Database, there is only one anticipation, a 5-minute game, Petasluk - givemeabreak, blitz, FICS, 2017.)

Jerome Gambit: When White Equalizes...

Given enough time, and the lack of distractions, some problems can be solved effectively. Facing the Jerome Gambit in a 1-minute bullet game doesn't allow for much time, and the Jerome, itself, can be quite a distraction.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ 

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 Qe7 9.O-O d6

10.f4 Nc6 11.Qc4+ Be6 12.Qe2 Rhf8 

An earlier game saw the Rook move to the e-file, i.e. 12...Rhe8 in angelcamina - pippol7, lichess.org, 2019 (1-0, 30).

13.e5 dxe5 14.fxe5 Nxe5 15.Qxe5 Kg8 

Black has returned the sacrificed piece for a pawn, and has an even game. He should remember the warning, however: When White equalizes in the Jerome Gambit, he has the advantage.

16.Bg5 h6 17.Bxf6 gxf6 

Black might have considered 17...Rxf6 18.Rxf6 Qxf6 19.Qxf6 gxf6, when he would have the same pawn weaknesses as in the game, but White would have fewer pieces to attack them. Black's Bishop vs White's Knight would probably keep the game even.  

18.Qg3+ Kh7 19.Rae1 Qc5+ 20.Qe3 Qxe3+ 21.Rxe3

Black follows the same general idea as given in the above note, but, as his time winds down, he now makes an unforced error.

21...Bf5

White now only has to make "safe" moves in order to make progress.

22.Rxf5 Rg8 23.Re7+ Kg6 24.Rf2 Rad8 25.Re6 Rgf8 26.h4 Kh5 27.g3 Kg4 28.Kg2 f5 29.Rf4+ Kh5 30.Re5 Rd6 31.Rexf5+ White won on time. 

White's extra piece and pawn were bound to win, anyhow.

Jerome Gambit: Quick Disappointment

In the following 1-minute game, it is clear that things did not go as planned, for Black.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ 

The Italian Four Knights Jerome Gambit. Black was looking for a balanced, quiet game, but this changed things.

4...Kxf7 6.Nxe5+ Nxe5 7.d4 Bb4 

Black has two extra pieces that he can return. He leads in development. Surely he is better? No, actually the game is about even. Nobody ever said that the Jerome Gambit made sense.

8.dxe5 Bxc3+ 9.bxc3 Nxe4

Sad. Best for Black was 9...Re8 10.exf6 Rxe4+ 11.Be3 Qxf6 12.0-0 d6, with an even game.

10.Qd5+ 

An improvement over 10.Qf3+, which still won, in angelcamina - puffy04, lichess.org, 2019 (1-0, 20) 

10...Kf8 11.Qxe4 d6 12.Ba3 Qg5 

Lashing out. Black tried 12...Be6 in angelcamina - apropes, lichess.org, 2019 (1-0, 21).

Black's King is at risk, and his defense fails. 

13.exd6 cxd6 14.Bxd6+ Kg8 15.O-O Bf5 16.Qd5+ Be6 17.Qxe6 checkmate

Jerome Gambit: More GMs? (Part 2)

[continued from previous post]

Next, I decided to check out the 19 Jerome Gambit games (all from online play) in The Database where the player of the black pieces was rated 2500+, looking, again, for another GM "in real life".

I quickly tossed Hera, MaxBot, GriffySr, Sly, Dampfwalze, wkw, birdcostello, Singularity, BlackDemon, and AnderssenA at FICS, as they were all computers. They were strong - Singularity and BlackDemon were rated over 2700 on the site - but they were not human.

That left me with Topper76, at at redhotpawn.com, who I had already tried to track down (see "Jerome Gambit: More GMs? Part 1"). There were also psv2398 (account closed), amaidel (St. Petersburg, Russia, FIDE 2347), RL12 (San Juan de los Morros, Cuba, FIDE 2333), Sveti14 (FIDE 2428 with the note "This player uses chess computer assistance"), Enialios (an open account but no FIDE rating listed) and PArnaudov, at lichess.org (the last one had already been looked at by Cliff).

Whew!

So, my search to find another human grandmaster who had faced the Jerome Gambit, even in online play, did not progress beyond the original investigation by "Cliff Hardy". No surprise there; after all, he is the private investigator, not me.

But I will still keep my (private) eyes open!

Jerome Gambit: More GMs? (Part 1)

I received an interesting email from "Cliff Hardy" the other day. In it, he notes

In the post about my game vs the Cuban GM, "A GM Faces the Jerome Gambit (Part 2)", you mentioned the virtually mistake-free game:  ChessCoachUA - PArnaudov, 3 0 blitz, lichess.org, 2017: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 d6 8.Qg3 Nf6 9.d3 Qd7 10.Nc3 Qg4 11.Qxg4 Bxg4 12.h3 Be6 13.Be3 Bxe3 14.fxe3 Ke7 15.O-O Rhf8 16.Nb5 c6 17.Nd4 Nd7 18.a4 Rxf1+ 19.Rxf1 Rf8 20.Rxf8 Nxf8 21.Kf2 g6 22.Nf3 Nd7 23.b3 a5 24.Ke2 Nc5 25.e5 dxe5 26.Nxe5 Kd6 27.d4 Nd7 28.Nd3 Bf5 29.g4 Bxd3+ 30.Kxd3 b5 31.axb5 cxb5 32.e4 a4 33.bxa4 bxa4 34.h4 a3 35.Kc3 Nb6 36.Kb3 Nc4 37.c3 Nd2+ 38.Kxa3 Nxe4 39.c4 Black lost on time; in which black maintains a winning advantage the whole game (from move 4), according to the Stockfish feature on Lichess (but loses on time in a winning position). I mentioned in a comment to the game that, in a slight anticlimax to my game being a rare example of a GM facing the Jerome Gambit, the black player PArnaudov is also a GM! https://lichess.org/@/PArnaudov

This certainly got me thinking! I responded quickly

The game ChessCoachUA - PArnaudov, 3 0 blitz, lichess.org, 2017, is a good example of why some skeptical people see the Jerome Gambit as only playable in very quick games. Black can figure it all out, but it might take too much time. Certainly angelcamina has found this out with his 1 0 games.

I was interested in learning that PArnaudov is a GM... 

For fun, I went to The Database and did a search for games with 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ and "ratings > 2500". I found 25 games, with 6 games where White was >2500. 

Wow! I was going to check out the games where the 2500+ player played the Jerome Gambit, first. The relevant games in The Database were all played online, not over-the-board.

One game was by BlackDemon, at FICS; it's a computer account; still, it might be fun to see if the Jerome is/was part of its book, the way "Brause" was set up to play the Halloween Gambit... 

Two of the games were by Topper76, at redhotpawn.com, in a Kentucky Opening tournament; I will have to track him down. Oddly enough, he won one Jerome Gambit game, on time, in 7 moves, and lost the other to a player rated 2421. 

Three of the games were by ChessCoachUA, at lichess.org - in fact, he was rated 2394, 2453, 2519, 2530, 2514 and 2459 on the site, for 6 Jeromes. Alas, ChessCoachUA's lichess.org account was listed as "closed", when I tried to check up on him.

Concerning the FICS computer account BlackDemon, I went to the online FICS games database, and found only 2 Jerome Gambits that it played with White, both in TheDatabase, one where the computer was "only" rated 2347 on the site. As a silicon beast, it couldn't be a grandmaster "in real life", anyhow.

I could not find a Topper76, at redhotpawn.com or elsewhere. Of course, those Jerome Gambit games were from 8 years ago, so the player may have moved on.

The ChessCoachUA story is a bit more complicated, and I had slipped up in my response to Cliff, above. The Database has 2 games by ChessCoachUA, as well as 2 games by ChessCoach_UA, and 4 games by ChessCoach1985. All of the players have lichess.org accounts listed as "closed", so it was not possible to do the kind of research that Cliff Hardy did with PArnaudov (above), to see if we were dealing with a GM in real life.

I tried, though.

I could find nothing on ChessCoach1985.

On the other hand, ChessCoach_UA, could well be Vasily Burishin, of Kiev, Ukraine. I could not find an FIDE rating.

I did find a ChessCoachUA at Chess.com - Alexey Pugach, of Dnepr, Ukraine, whose FIDE Chess Profile lists his rating as 1985. Of course I messaged him.

So - the search to find a human GM (FIDE rating, not online site rating) has not (yet) been successful.
