kristjan - procyk
RedHotPawn, 2016
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d3 h6
The game has transposed to a Semi-Italian Jerome Gambit line where White temporized with d2-d3, i.e. 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.d3 Bc5 5.Bxf7+ Kxf7.
White now decides on the "classical" second piece sacrifice. It is interesting to note that a first round game, deriver69 - procyk, transposed into the continuation 6.0-0 (0-1, 25).

8.Qf5+ Kd6 9.Nc3
Development is a good thing in a gambit, but White might have had more luck with 9.f4. There are only two games with that move in The Database, but White won both.

10...Qf6
11.Bxe5+
Likely better was 11.O-O-O, although the position would still be difficult.
11...Qxe5 12.Qf3 Nf6 13.O-O-O Bd4 White resigned
The ending comes abruptly, but White may have decided that he simply did not have enough compensation for his two pieces. It will take some work to get any kind of attack on the King going.

























Here we have a "typical" Jerome Gambit middlegame: a real mess.
The wrong choice.
A perplexing move, not only allowing 18.Qf5+ drawing as above, but also allowing the flashy 18.Bd6+ which also draws.
White's response in the game, however, allows the routine capture of his Knight, and the magic is again gone.
18.Qg6 dxe4
The light-square weaknesses are still around the Black King, but White no longer has his Knight to keep check-blockers off of f6.
Instead of interposing the Queen with 20...Qf6, allowing 21.Qc5+ and 22.Qxc2, reducing his advantage, Black again allows the light-square repetitions and the draw: 21.Qe6+ Kh7 22.Qf5+ Kg8 23.Qe6+ etc.

This move should seriously scare White into going for a draw. For a moment, it looks like it does.
Okay: Now, after 23...Kxg7 24.Rg4+ Qg5 25.Qd7+ Kf6 26.Rxg5+ hxg5 27.Qxd2 White will have a Queen and a pawn to balance out Black's two Rooks. A complicated, but roughly even, game.
26...Ke6 27.Qh6+ Kd7
Now 28.Qh5, guarding against the passed pawn Queening (if 28...Kc8, 29.Rf8) and preparing to finish up the King, looks like the proper reward for White's fighting spirit.
Unfortunately, he has a worried eye on Black's passer, and decides that "more checks to the King" is the answer. It is not – but the excitement is hardly over.
Black can afford to allow his Queen to be pinned to his King: he plans on getting another one.
29.Qe6+ Kb8 30.Kh2 d1Q
Black has travelled far from his "doomed situation" mentioned in the note to White's 23rd move. He figures from here on out, it's just a matter of technique.
What was called for was something that ends the clutter, something like 31...Qxf8 32.Bxf8 Qd8.
Black's move, however, lets loose the chaos again.
White now has the remarkable 32.Qe7, after which, despite being a Queen down, he can enforce the draw, obtain a better position, or checkmate Black: 32...Ka7 ( 32...Qc8 33.Rxc8+ Kxc8 34.Qf8+ Qd8 35.Qf5+ Qd7 ( 35...Kb8 36.Qxc2 +-) 36.Qf8+ Qd8 37.Qf5+ draw) 33.Qc5+ b6 34.Rxd8 Rxd8 35.Qxc7+ Ka8 36.Qc6+ Ka7 37.Qc7+ draw
Amazing!
32.Rxd8+
Aquiescing to the loss. Well, not exactly: White still has a handful of "Jerome pawns" and decides to put them to use. Still, thirty moves later White resigned. 

Black is surprised, and makes a poor response.
Black has some open lines (that he has purchased with his pawns) which he can place his Rooks on, but they are not adequate compensation.
