I give below the moves of a blitz game I played tonight on the Internet Chess Club. The moves are not accurate, as we had just five minutes each to complete the game, and we are both dilettantes. But the attack I played was so simple it played itself, so maybe this is a good training example… I am white against a first-category player (HerrTrigger his ICC handle).
1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Nf6 5.Nxc6 bxc6 6.Nc3 Bb4 7.Bd3 0-0 8.0-0 d5 9.exd5 cxd5 10.Bg5 c6 11.Qf3,
Up to now, nothing of our own making – you can find the above sequence on any chess opening book. It is called “Scotch game”; this particular variation is not known for causing black any particular opening problem, but white’s setup is solid and lends itself to a quick kingside surge, if black does not play the most accurate moves.
Sub-optimal. Black has to be careful of his dark squares, and the pin of the Nf6 required more attention. Now white gets a clear initiative.
The start of a straightforward idea – Ne2-d4-f5 will further weaken the dark squares around the black king.
12…. Rb8 13.Nd4
Now Nxc6 is threatened, and the queen cannot defend the pawn since it is tied to the defence of the Nf6.
But this is surely a mistake. Black places the lightsquared bishop on a passive square, blocking the open b-file for some counterplay by the Rb8, and totally leaves the f5 square undefended.
This is the position bfore the start of the final attack. First of all, the black bishop is targeted, gaining a tempo with the rook.
Now black threatens Bxh2+, but this is not really a problem for white. Instead, the logical conclusion of the knight manouver is in the air…
If now black takes the N, white wins both by 17.Qf5 and by means of the pretty 17.Rxe5! Qxe5 (17…. hxg5 18.Rxg5+ Kh8 19.Qxf6 mate) 18.Bxf6, and black is soon mated (18…Qe6 19.Qg3+).
The simplest way to win. Black resigned, since on both 17….Bxf6 and 17….gxf6 there follows 18.Qf5 and there is no way to avert Qxh7 mate, while on 17….Bxh2+ 18.Kh1 Qf4 19.Qh5 Qxf6 (19….Qxh6?20.Qxh6) 20.Nxf7+! Kg8 21.Bxh7+ is mate. The Nc3-e2-d4-f5-h6 manouver is pretty in this game, since all the moves are active, and by threatening in turn the c6 pawn, the d6 bishop, and the king the knight takes the lion’s share of merit for the attack.
One word of warning: the above variations are the result of some thoughts on the game diagram, without even moving pieces on a real chessboard, let alone running a check with Fritz. So I am most likely going to be refuted by deeper silicon analysis… To me, the game and the variations still look quite logical in their development and conclusion!
