In the first of my two Italian Game tournaments at Chess.com I have won one game and am near another win. Both of them are technical endgames.
In my second tournament, I suffered a loss when my "brilliant" Queen sacrifice did not lead to a back rank checkmate, after all... Awkward.
However, I have just completed a win with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), and that is enough for me to consider the tournament a success, already!
perrypawnpusher (1636) - Vaima01 (1773)
Italian Game - Round 1 Chess.com, 2012
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
This is a natural response, prudently returning one of the two sacrificed pieces; yet, I am always glad to see it, as it leads to interesting clashes between the "Jerome pawns" and Black's extra piece, and the chess engines usually show a gradual slip into an even game after about a dozen moves.
7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Qe7
10.Nc3
Or 10.d4, as in mrjoker - lilred, ICC, 2009 (1-0, 50); or 10.0-0 as in mrjoker - blind25, ICC, 2009 (0-1, 66) and perrypawnpusher - Edvardinho, blitz, FICS, 2010 (1-0, 57).
10...Nf6 11.0-0 Be6
A bit more active was 11...Rf8, as in perrypawnpusher - MRBarupal, blitz, FICS, 2010 (0-1, 31) and perrypawnpusher - chingching, blitz, FICS, 2011 (½-½, 36).
An alternate development of Black's Bishop was seen after 11...b6 in perrypawnpusher - Navarrra, blitz, FICS, 2011, (1-0, 24).
12.f4 Bf7
Black's move is sensible. There have been a variety of alternatives:
The frisky 12...Bc4 was seen in perrypawnpusher - ZhekaR, blitz, FICS 2011 (0-1, 36) and perrypawnpusher - tuffnut, blitz, FICS, 2012 (1-0, 62);
The retreat 12...Bd7 appeared in perrypawnpusher - Unimat, blitz, FICS, 2011 (1-0, 25);
The bold 12...Kd7 was tried in perrypawnpusher - Solaar, blitz, FICS, 2011 (33); and
The counter-attacking 12...Ng4 erupted in Wall,B - Hirami,Z, Chess.com, 2011 (1-0, 20).
13.f5 Ne5 14.d4 Nc6 15.Qd3 Kd7 16.e5 Ne8
Black opts for the scientific solution of returning a piece for two pawns, with the goal of leveling out the position and the game.
After the game, however, Rybka suggested the way to do that would have been by 16...Nxe5 17.dxe5 Qxe5. It turns out that there is a glitch or two in giving back the Bishop.
17.e6+ Bxe6 18.fxe6+ Kd8
The second pawn is not easily taken, as after 18...Kxe6 there is 19.Qf5 checkmate; and after 18...Qxe6 White has 19.d5.
White is now better, but it took me a while to figure out how to proceed.
19.d5 Ne5 20.Qf5 h6 21.Bf4 Rf8 22.Qh3 Rf6
This helps, although in the end I decided to settle for the win of another pawn, with a strong position.
23.Ne4 Rf8 24.Bxe5 dxe5 25.Qg3 Nf6 26.Qxe5
26...Nxe4 27.Qxe4 Qc5+ 28.Kh1 Ke7 29.Rf7+
My favorite move of the game. It's success is based on finding a "quieter" move later on.
29...Rxf7
After the alternative, 29...Ke8, I had planned 30.Raf1 and Black does not have long to live.
30.exf7+ Kxf7
I was happy to see that after 30...Kf8 I would have the nice move 31.Re1
31.Qe6+ Kf8 32.Rf1+ Qf2 Black resigned
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ ...and related lines

It all adds up
I have mentioned elsewhere GM Bronstein's lighthearted comment that in chess, three small errors tend to add up to one big error. In the following game, Black suffers a loss more because he loses his way against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxv7+) than because of any great blunder.
perrypawnpusher - Unimat
blitz, FICS, 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
10.0-0 Qe7 11.Nc3 Be6
Black has any number of alternatives, including 11...b6 as in perrypawnpusher - Navarrra, blitz, FICS, 2011, (1-0, 24); 11...Rf8 as in mrjoker - rex3, Internet Chess Club 2009 (1-0, 50), perrypawnpusher - MRBarupal, blitz, FICS, 2010 (0-1, 31), perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 20) and perrypawnpusher - chingching, blitz, FICS, 2011 (½-½, 36); 11...Ne5 as in perrypawnpusher - mikelars, blitz, FICS, 2011 (1-0,50); and 11...Kd7 as in perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 22).
The text encourages White to play f2-f4-f5.
12.f4 Bd7
Losing a tempo.
The alternative, 12...Bc4, was seen in QuadCoreBR - Alecs, blitz, FICS, 2008 (1-0, 27) and perrypawnpusher - ZhekaR, blitz, FICS, 2011 (0-1, 36).
Too risky is 12...Kd7 as in perrypawnpusher - Solaar, blitz, FICS, 2011 (1-0, 33).
13.f5 Ne5 14.d4 Nc4 15.Qd3 Nb6
The "Jerome pawns" are rolling and White has the advantage.
16.Bg5 h6 17.Bh4 Qf7
Moving out of the pin on the Knight, but it is interesting to see what Houdini recommended after the game: 17...Rd8 18.e5 dxe5 19.dxe5 Bc6 20.exf6 gxf6 21.Qg3 Kd7 22.Rae1 Qc5+ 23.Qf2 Qxf2+ 24.Rxf2 Rde8 25.Rfe2 Rhf8 26.Rd1+ Kc8 27.Rxe8+ Rxe8 28.Bxf6 Nc4 29.Nd5 Bxd5 30.Rxd5 Ne3 31.Re5 Rxe5 32.Bxe5 Nxf5.

White's attack has been neutralized, but his extra pawn and Bishop vs Knight should win in the end.
18.e5 dxe5 19.dxe5
19...Nfd5
This raises the level of danger, but Houdini's suggestion 19...Qc4 20.Qxc4 Nxc4 21.exf6 will lead to a two-pawn advantage for White, any way.
The tactics all go White's way now.
20.e6 Qh5 21.exd7+ Kxd7 22.Nxd5 Nxd5 23.Qxd5+ Kc8
24.g3
The computer later pointed out that the Bishop was untouchable: 24.Rad1 Qxh4 25.f6 leads to mate.
24...Rd8 25.Qxd8 checkmate
