Accelerated Instant Victory

I am not particularly a fan of the Accelerated Semi-Italian Jerome Gambit, but for those who play it, the following game should be a reminder that a false move like 5...Ke8 for Black can lead to another kind of Instant Victory.

Ghandy - Kwanza
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.Bxf7+

White does not wait for a Black Bishop to appear at c5, he sacrifices anyhow. Although the opening does not appear to have a name, it looks like an Accelerated Semi-Italian Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8

Perhaps thinking, on reflex, that the King will be safer here. However, we will now see an ending similar to that presented in "Instant Victory" and "Instant Victory Redux".

6.Qh5+ Ke7

Black can throw in 6...g6 as in GFcrafty - Suigeneris, blitz, FICS, 2001, but after 7.Qxg6+ the result will be the same.

7.Qf7+

Also successful was 7.Ng6+ Kd6 8.Qd5 checkmate as in Dasistes - GeorgeVonGeorge, blitz, FICS, 2008.

However, 7.0-0 was not successful, as in EvashUcrushU - mrcain, FICS, 2009, which continued 7...Nxe5 (7...Qe8 was a bit better) 8.Qh4+ (White should have taken the draw by repetition with 8.Qxe5+ Kf7 8.Qd5+ etc.) g5 9.Qg3 d6 White resigned.

7...Kd6 8.Nc4+

Not quite as accurate was 8.Qd5+ but it was sufficient for the full point after 8...Ke7 9.Ng6+ Ke8 10.Nxh8 Nce7 (falling on his sword) 11.Qf7 checkmate in Esistes - SURPRISE, blitz, FICS, 2010.

8...Kc5 9.Qd5+ Kb4 10.c3+ Ka4 11.b3 checkmate

Today's game is the same as GFcrafty - tomamelheim, blitz, FICS, 2001. 

Good things come to those who... work!

When Jerome Gambit Gemeinde member Welton Vaz started the following game, I doubt that he realized the gigantic struggle that lay ahead of him. I'm pretty sure that his opponent figured that a win was only a matter of time – it was, but for White.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6

The Semi-Italian Opening.

White's typical "Jerome treatment" is to play a temporizing move like 0-0 or Nc3 now, hoping for ...Bf8-c5, allowing the signature Bxf7+. 

4.Bxf7+

Wow.

This reminds me of Veijoasquerosos of Mexico, who played over 1,100 games at RedHotPawn.com, and who played Bxf7+ (or ...Bxf2+) as early and as often as possible: see "King of Bxf7+".  

I've played the move myself, although accidentally: perrypawnpusher - marapr, blitz FICS, 2007 (1-0, 27).

A look at the updated New Year's Database shows 904 games with this position, with White scoring 39%.

One of the top users of 4.Bxf7+ here is GFcrafty (a weakened version of Crafty, the free, open-source computer chess program developed by Dr. Robert M. Hyatt) at FICS.

Perhaps the most important of those games, however, is Gandybh - sqerl, Chess.com, 2009 which shows that Welton has played the line before, and is ready to face his opponent.

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

Rybka, in its "blunder check" mode (5 minutes per move), suggested 6.d4 Nc6 7.Nc3 d6 8.0-0 Nf6 9.h3 Be7 10.d5 Nb8 11.Be3 Re8 12.Re1 as better. The line looks like no fun at all. Maybe when the "Jerome pawns" get rolling...

6...Ng6 7.Qd5+ Ke8

White has his work cut out for him.

8.d3 Nf6 9.Qf5 Ne7 10.Qf4 Nc6 11.0-0 Nd4 12.Qe5+ Ne6 13.Be3 Qe7

14.Nc3 d6 15.Qb5+ c6 16.Qb4 c5

It looks like Welton's play has begun to annoy his opponent who would probably prefer "16.Resigns."

Good.

17.Qb5+ Bd7 18.Qxb7 Rc8 19.Qxa7

White now has 4 pawns for his 2 sacrificed pieces. That's not enough, but it's more than he had a few moves ago. Also, Black's King is stuck in the center, and at least for now his King's Rook is buried in the garage.

19...Ng4 20.Nd5 Qd8 21.h3 Nxe3 22.fxe3 Be7 23.Nxe7 Qxe7

Black has made progress in one area – when ahead in material, exchange pieces – but he still has an opponent fighting back.

24.Qb7 Rf8 25.Rxf8+ Qxf8 26.Rf1 Qe7 27.a3

Here's a clue: White believes that his "Jerome pawns" will one day be able to take on Black's two extra pieces in the endgame.

27...Rc7 28.Qb8+ Qd8 29.Qb6 Rc6 30.Qxd8+ Kxd8 31.Rf7

31...Ke8 32.Rf1 Rb6 33.b3 Ra6 34.a4 Ng5 35.h4 Nf7

Black has been teasing and provoking the pawns. No harm done. So far.

36.Kf2 Ne5 37.Ke2 d5

To open a path to swing the Rook over – but, a pawn is a pawn.

38.exd5 Rf6

39.d4

Hesitating. It was okay to exchange the Rooks.

39...cxd4 40.exd4 Bg4+ 41.Ke1 Rxf1+ 42.Kxf1 Nd7

Now the fun really begins.

White's plan is pretty clear: have his King escort the five connected past pawns forward, until one or more of them Queens.

Black has to counter this. Ideally, if he can hold up the pawns with his King and only one piece, then he can use (or sacrifice) the other to create a winning passed pawn on the other side of the board.

43.Ke1 Ke7 44.Kd2 Kd6 45.c4 Bf5

46.Kc3 Nf6 47.b4

47...Ne4+ 48.Kb3 Nd2+ 49.Kc3 Ne4+ 50.Kb3

White is willing to repeat the position and accept the draw.

50...Bd7

Black can't bring himself to "lose" the half-point.

51.a5 Nd2+ 52.Kc3 Ne4 53.Kb3 Nf2

Again Black wavers – and then decides "no draw". His problem is that now White's game gains momentum.

54.a6 Kc7 55.b5 Kb6

Rybka suggested instead : 55...Ne4 56.Kb4 Nd6 57.a7 Kb7 58.b6 Nc8 59.c5 Nxa7 60.bxa7 Kxa7 when it looks like Black's King and Bishop may be able to hold up White's central pawns (and draw) after all.

56.c5+ Ka7 57.c6 Bc8

Black's Knight is sadly out of play. 

58.d6 Ne4 59.d7 Nd6

60.d8Q Nxb5 61.Qxc8 Nd6 62.Qd7+ Nb7 63.Qxb7 checkmate

Very nice work. As they say, nobody ever won a game by resigning...
