In a humorous vein I have referred to the chess clock as the "33rd piece" and the computer mouse (for online games) as the "34th piece", as each can have a profound effect on the outcome of a chess game - especially a game featuring the unorthodox Jerome Gambit.
In the following battle Black takes the sacrificed material, exchanges pieces, enters a winning endgame and... and... and...
and apparently runs out of time (or ideas?) and forces a draw through the repetition of moves.
Weird.
Which is kind of normal for the Jerome Gambit.
Wall, Bill - Kar, Bob

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.O-O h6
Interesting. Bill opts for a "modern" (non 5.Nxe5+) Jerome Gambit variation by castling. In return, his opponent transposes the game to a Semi-Italian Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0 Bc5 5.Bxf7+ Kxf7).
It is funny to note that now Stockfish 8 recommends Bill's following, "classical" Jerome Gambit move.
6.Nxe5+ Nxe5 7.d4
Bill has also played the equally-strong 7.Qh5+: 7...Ke6 (7...Ng6 8.Qd5+ Ke8 9.Qxc5 d6 10.Qc4 Ne5 11.Qb3 Qe7 12.d4 Nc6 13.d5 Nd4 14.Qa4+ Bd7 15.Qxd4 Qe5 16.Qxe5+ dxe5 17.f4 exf4 18.Bxf4 c6 19.c4 Nf6 20.e5 Nh5 21.e6 Nxf4 22.exd7+ Kxd7 23.Rxf4 Black resigned, Wall,B - Castro,S, Chess.com, 2010) 8.Qf5+ Kd6 9.d4 Bxd4 10.Rd1 Ke7 11.Rxd4 d6 12.Qf4 Nf6 13.Nc3 Qf8 14.b3 Be6 15.Nb5 Kd7 16.Qxe5 Ng4 17.Qg3 Qf6 18.Bb2 Rhf8 19.Rxd6+ cxd6 20.Bxf6 Rxf6 21.Qxd6+ Black resigned, Wall,B - Guest473534, PlayChess.com 2011
7...Bxd4
This direct move makes the most sense, especially in light of Black having spent time on ...h6. Still, Bill has seen other moves:
7...Bd6 8.dxe5 Bxe5 9.Qh5+ Ke6 10.Qf5+ Kd6 11.Rd1+ Kc6 12.Qxe5 Qe7 13.Qd5+ Kb6 14.Be3+ c5 15.Nc3 d6 16.Qxd6+ Qxd6 17.Rxd6+ Kc7 18.Nb5+ Kb8 19.Bf4 Black resigned, Wall,B - Guest7561588, PlayChess.com, 2016; and

8.Qxd4 Qf6
Putting the Queen on an often-useful square, and threatening the very blunt 9...Nf6+. Once again, Bill has faced other continuations:
8...Nc6 9.Qd5+ Kf8 10.Nc3 Nf6 11.Qb3 d6 12.Be3 Qe7 13.f3 Na5 14.Qb5 b6 15.Rfe1 Bd7 16.Qf1 Kf7 17.Nd5 Qd8 18.Rad1 Re8 19.Bf2 c6 20.Nxf6 Qxf6 21.b4 Nb7 22.Qa6 Bc8 23.Bd4 Qe6 24.Bxb6 Nc5 25.Qa3 Nd7 26.Bc7 Qc4 27.Bxd6 Nb6 28.Bc5 Be6 29.f4 Bg4 30.Rd4 Qxc2 31.f5 Nc4 32.Qg3 Ne5 33.Bd6 Bh5 34.Bxe5 Be2 35.Qxg7 checkmate, Wall,B - Anonymous, lichess.org, 2016;

9.Rd1
Another way to deal with the threat was 9.Be3 d6 (9...Ne7 10.Nc3 Rf8 11.Nb5 c6 12.Nc7 Rb8 13.f4 Nf3+ 14.Rxf3 Qxd4 15.Bxd4 Kg8 16.Bxa7 Black resigned, Wall,B - Foman, Chess.com 2010) 10.Nc3 c5 11.Qd1 g5 12.f4 gxf4 13.Rxf4 Black resigned, Wall,B - NN, lichess.org, 2016.
9...d6
10.h3
Letting Black take the first step, but this allows the annoying 10...Bxh3!? 11.Qc3 Bxg2!? 12.Kxg2 Qg6+ 13.Kf1 Qxe4 when Black has returned the sacrificed piece for three pawns, while destroying the pawn cover of the White King.
10...Ne7 11.Nd2 c5 12.Qc3 Rf8 13.Qb3+ Qe6 14.Qxe6+ Bxe6
With an extra piece (for only a pawn) and better development, Black is clearly on top in this game. However, he still needs to show what he can do with his advantage, and that proves to be a challenge.
15.f4 N5c6 16.f5 Bd7 17.g4
Nothing like a Kingside pawn storm to get the blood pumping. Black decides to castle-by-hand right into it.
17...Kg8 18.h4
18...Rad8 19.Nf3 Bc8 20.c4 Ne5 21.Nxe5 dxe5 22.Rxd8 Rxd8
Exchanging pieces has helped Black by reducing the size of the possible attacking force. The Queenless middle game is looking a lot like an ending, where the extra piece will be of help.
23.Be3 b6 24.a3 Rd3 25.Bf2 Nc6 26.b4 Nd4 27.bxc5 bxc5 28.Rb1 Rb3 29.Rxb3 Nxb3 30.Kg2 Ba6 31.Bg3 Bxc4 32.Bxe5 Bd3
Things are beginning to look scary for White. On the other hand, they have looked scary since the opening, so everything is relative. The Jerome Gambit is not for the nervous; it is for those who can stay continuously aware of opportunities as they present themselves. Nobody ever won a game by resigning, either.
33.Bb8 a5 34.Kf3 c4 35.Ke3 a4 36.Bd6 Kf7 37.g5 hxg5 38.hxg5 g6
In theory, exchanging pawns should help White. A passed pawn or two wouldn't hurt, either. Any weapon to fight back with.
39.f6 Na1 40.Bc5 Nc2+ 41.Kd2 Na1
This looks like a clock issue.
42.Ke3 Nc2+ 43.Kd2 Na1 Drawn by repetition
I recently referred to the chess clock as "the 33rd piece" (see "Strangest Beast") because it sometimes has a profound effect on the outcome of a game - sometimes as much as a Queen or more.
In the following game I have reason to suspect "the 34th piece" - the computer mouse, inputting moves in an online game. Its effect on my opponent's 16th move - if it was a mouse-slip - is rather off-putting and unfortunate.
Once again, the truism: In the Jerome Gambit, Black wins by force, White wins by farce. (Well, in my games, anyhow.)
perrypawnpusher - aksakal
blitz 5 7, FICS, 2017
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ Kxf7
The Italian Four Knights Jerome Gambit. I have 59 games with it in The Database, scoring 74%.
6.Nxe5+
After the game I was interested to discover in The Database the game olivercsc - aksakal, FICS, 2015, in which Black outplayed his opponent, but was done in by his clock: 6.O-O h6 7.d3 d6 8.h3 Rf8 9.Bxh6 gxh6 10.Nd5 Nxd5 11.exd5 Nd4 12.a3 a5 13.Nd2 Qg5 14.Ne4 Qg6 15.Ng3 Kg8 16.Qh5 Qxh5 17.Nxh5 Nxc2 18.Rac1 Nd4 19.Kh1 Ne2 20.Rce1 Nf4 21.Ng3 Bd7 22.Ne4 Nxd3 23.Rd1 Nxf2+ 24.Nxf2 Rxf2 25.Rxf2 Bxf2 26.Rd3 Rf8 27.b4 Bg3 28.Rxg3+ Kh7 29.bxa5 e4 30.Kh2 Ba4 31.Re3 Bc2 32.Rc3 Bd3 33.Rxc7+ Kg6 34.Rxb7 e3 35.Rb6 e2 36.Rxd6+ Kg5 37.h4+ Kg4 38.Re6 Black forfeited on time.
My Jerome Gambit probably did not worry my opponent a bit.
6...Nxe5 7.d4 Ng6
A novelty. The Knight sometimes goes to g6 in other lines of the Jerome Gambit.
Here, best is 7...Bd6. Interestingly enough I have only faced that
move twice, and am 1-1.
That lack of "best" play reinforces Bill Wall's understanding of the opening's "playability" in casual, online, and fast games - the Jerome Gambit's "refuted" nature is often counter-balanced by the defender's lack of concrete knowledge about those refutations.
8.dxc5 Re8 9.Bg5 h6 10.Bxf6 Qxf6 11.O-O Kg8
Black has castled-by-hand and has his Rook on an open file.
12.f4 d6 13.cxd6 Qxd6 14.Qxd6 cxd6 15.Rad1 Be6
My opponent took some time deciding on the offer to exchange Queens. I agreed to the swap, immediately - which caused him to take some more time figuring out what I was up to.
I admit to being under the influence of the recent Philidor1792 bullet games posted on this blog. If our clocks were going to run down (his faster than mine, so far) I was going to be comfortable with a simpler position.
16.Rxd6
An immediate example of "simpler". I suspect that my opponent expected me to play the fork 16.f5, although 16...Bc4 17.fxg6 Bxf1 18.Rxf1 Re6 was probably even, as White would wind up with one or two pawns for the exchange.
16...Ne5
It is hard to read this as anything other than a mouse-slip.
What to do about the threatened pawn fork? Black could keep busy with 16...Rad8 17.Rxd8 Rxd8 and then 18.f5 could again be answered by 18...Bc4 19.Rd1 (I prefer this to 19.fxg6) Rxd1+ 20.Nxd1 Ne5 and White will move his King to the center, counting on that - and his 3 pawns for the piece - to fight against Black's edge (especially with the time clock advantage).
17.fxe5 Black resigned
An unfortunate end to an interesting encounter.
Recently I received some Jerome Gambit games from long-time unorthodox openings expert Bill Wall. He pointed out
My chessbase database says I have played 352 Jeromes without transposition and I just now discovered the statistics page with a 93% winning advantage. I have 168 games with 6.Qh5 (90% winning percentage) and 138 games with 6.d4 with a 90.6% winning percentage. Pretty even.
I have now played 50,817 chess games that I have a recorded game since 1969. I should hit 51,000 before the end of the year.
One reason (besides skill and knowledge) that Bill does so well with the Jerome Gambit is that his opponents do not take the opening seriously - to their dismay, as he does.

Here is the last game of the Philidor1792 - Slayman match, testing a particular opening. With a time control of 2 0, the outcome rests on any number of things, including the "33rd piece" - the clock.
Again: a 2-minute game is almost too fast for me to breathe, let alone play interesting chess. Nice work, gentlemen.
Philidor1792 - Slayman
2 0 bullet, lichess.org, 2017
1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.Nf3 Nc6
After the first three moves we have come to expect, White tosses in 4.Nf3 and Black adds 4...Nc6, bypassing the Urusov Gambit and moving on to the Two Knights Game, although lichess.org labels the line "Scotch Game: Scotch Gambit, Dubois Reti Defense".
5.Bxf7+
The Jerome-ish sacrifice.
5...Kxf7 6.e5 Ne4 7.c3 d5
Again, White seeks to develop after 7...dxc3 8.Nxc3, and again Black does not cooperate - this time moving his other d-pawn.
8.cxd4 Bb4+ 9.Nbd2 Rf8 10.O-O Bxd2 11.Bxd2 Kg8
Black has castled-by-hand and retains his extra piece.
White's protected passed "Jerome pawn" is not yet a factor in the game.
12.h3 Be6
(In a slower game it would be worth pointing out 12...Rxf3 13.Qxf3 Nxd2 )
13.Be3 Qe8 14.Rc1 Qh5
15.Kh2
White sees there will be trouble on the Kingside, but might have done better to offer the exchange of Queens with 15.Ng5.
15...Bxh3 16.Ng1 Qxd1
Black does White a favor. The Queen exchange takes the energy out of the attack - but it also makes calculation in the position a bit easier; and the second player still maintains his advantage.
17.Rfxd1 Be6
Black has the extra piece - but the clock is ticking away.
18.f3 Rad8 19.fxe4 dxe4 20.Ne2 Nb4 21.Rxc7
When in doubt, and time trouble, grab material.
Stockfish 8 recommends the rambling line 21.Nf4 Bg4 22.Rd2 c6 23.Kg3 Bf5 24.Rf2 Nd3 25.Nxd3 exd3 26.a4 h6 27.Rcf1 Be4 28.b4 Rxf2 29.Rxf2 Bd5 30.Rd2 Bc4 31.Rf2 g5 32.Rf1 Kg7 33.Rf2 Rf8 34.Rxf8 Kxf8 35.Kf2 Ke7 36.Bc1 Ke6 which it sees as favoring Black, but which looks pretty drawish due to Bishops-of-opposite-colors.
21...Nd3
Not enough time to figure out 21...Nd5 22.Rc3 Bg4 23.Rd2 Bxe2 24.Rxe2 Nxc3 25.bxc3 Kf7 and the extra exchange helps Black.
22.b3 White won on time.
Continuing to present the games from the bullet match at lichess.org between Philidor1792 and Slayman, using the unusual Jerome Gambitish line mentioned a couple of posts ago - see "Jerome Gambit: Strange Beast".
Philidor1792 - Slayman
2 0 bullet, lichess.org, 2017
1.e4 e5 2.Bc4 Nf6 3.d4 exd4 4.Bxf7+
Here we go. Philidor1792 was successful with this line in this rocket-fast match, winning three games, drawing one, losing none.
4...Kxf8 5.e5 Ng8
As we have seen, the best defense starts with 5...Qe7 6.Qe2 Ne8. However, in a 2 0 game you barely have time to breathe, let alone analyze deeply. Knowing anything about the line is a great advantage.
6.Nf3 Bc5 7.c3 d3
Black has no intention of helping White's development with 7...dxc3 8.Nxc3.
8.Qxd3 Bb6 9.O-O Ne7 10.Qc4+ Kf8 11.Bg5 h6 12.Bf4 Rg8
"Objectively" Black is better, with a piece for a pawn, but his position is horribly cramped and undeveloped.
13.Nbd2 g5 14.Bg3 Nbc6 15.Ne4 Nf5 16.Nf6 Nxg3
Yipes! This overlooks a checkmate-in-two.
17.Qxg8+ Ke7 18.Qg7+
Move, move, move! Missing 18.Nd5#. Move, move, move!
18...Ke6 19.hxg3 Nxe5 20.Nxe5 Qxf6 21.Qxf6+ Kxf6
In a game with a slower time control, exchanging Queens would not be the best plan. Here White is up the exhange, and he can calculate better (and faster) with fewer pieces on the board.
22.Nc4 d5 23.Nxb6 axb6 24.a3 Be6 25.Rae1 c5
Black needs to activate his Queenside pawn majority.
26.Re3 d4 27. cxd4 cxd4 28.Re4 Rd8 29. Rd1 d3 30.Rd2 Bf5
31.Rb4 Rc8 32.Rxb6+ Rc6 33.Rxc6+ bxc6 34.f3 Ke5 35.Kf2 Kd4
36.g4 Bg6 37.g3 Kc4 38.Ke3 Kb3
39.Rxd3+
An option always available to the one ahead the exchange.
39...Bxd3 40.Kxd3 Kxb2 41.Kd4
Nice. White could have decided to run his a-pawn, but after 41.a4 Kb3 42.a5 c5 43.a6 c4+ 44.Ke4 c3 45.a7 c2 46.a8/Q c1/Q both of the Queens are back on the board, and calculation becomes a bit more time-intensive. Only the clock can beat White now, so he keeps it simpler.
41...Kxa3 42.Kc5 Kb3 43.f4 Kc3 44.f5
Now there will be only one Queen on the board, and White only needs one...
44...Kd3 45.f6 Ke4 46.f7 Kf3 47.f8=Q+ Kxg3 48.Qxh6 Kxg4 49.Kxc6
Alas for Black, if his remaining pawn were either the f-pawn or h-pawn - and more advanced - he would still have drawing chances. Was not to be...
49...Kg3 50.Qxg5+ Kh2 51.Qg4 Kh1 52.Kd5 Kh2 53.Ke4 Kh1 54.Kf3 White won on time
Each player spent around 2 seconds per move.
Following up on the previous post (see "Jerome Gambit: Strange Beast"), Philidor1792 sent me four games he recently played with the line (as White) in a match against Slayman, at lichess.org, at the quick speed of 2 minutes with no increment per game. Philidor1792 scored 3 1/2 - 1/2.
It is fun to first look at the two shortest - and funniest - games.

1.e4 e5 2.Bc4 Nf6 3.d4
This is identified at lichess.org as "Bishop's Opening: Ponziani Gambit".
3...exd4 4.Bxf7+
This is not a Jerome Gambit, but it has a Jerome feel about it, and certainly is equally outrageous.
Of course, White also had 4.Nf3, offering the Urusov Gambit; and Black could have further declined with 4...Nc6, the Two Knights Defense.
4...Kxf7 5.e5 Ne8
The proper defense, maintaining Black's advantage, as shown in saprvade - Philidor1792, 3 2 blitz, lichess.org 2016 is 5...Qe7 6.Qe2 Ne8 etc.
6.Qf3+ Kg6
I was amused to see that Stockfish 8 assessed the silly alternative, 6...Nf6, as completely equal (0.00), recommending the equally silly 7.Qd1, even with an analysis depth of 25 ply.
Of course, Stockfish is confused by the possibility of repeating the position, resulting in a draw - just play the two moves and the computer leaps to point out, of course, that Black is better by 2 2/3 pawns.
After the text move, however, Stockfish 8 assesses the top 6 replies by White to lead to complete equality (0.00) again.
7.Nh3 h6 8.Nf4+ Kf7
Remember: this is a 2-minute game, and any retreat probably looks the same as any other retreat. But: not so.
The proper line was shown in another one of the games in the match: 8...Kh7 9.Qe4+ Kg8 10.Qd5+ Kh7 11.Qe4+ Ke8 12.Qd5+ Kh7 13.Qe4 drawn (by repetition).
