1.e4 e5 {I was fairly confident Bas would have been expecting d5. (RJ)} 2.Nf3 Nc6 3.Bb5 {Bas has studied and played the Ruy for many years, so this was easy to predict. (RJ)} f5 4.Nc3 fxe4 5.Nxe4 d5 {Feeling confident Bas would boldly go in for the piece sac and into the line I had prepared. (RJ)} 6.Nxe5 dxe4 7.Nxc6 Qg5! {Not my idea, but found on Chessbase in my preparation that morning. I was very happy when I saw this, feeling sure that Bas wouldn't have anticipated it, and that it would be very difficult for him to find the right line over the board. (RJ)} 8.Nxa7+?! {After about 25 minutes thought. Not bad, but the right move is Qe2! Black now has the advantage. (RJ)} Kd8 $15 {Not c6, after which White has the edge. (RJ)} 9.d3 Qxg2 10.dxe4+! {Bas said afterwards he had overlooked my reply. But de is the best move anyway. (RJ)} Bd6 11.Qd4? {Rf1 is necessary. Black now has a decisive advantage. (RJ)} Qxh1+ $19 12.Bf1 Bh3 {Rxa7 is better. (RJ)} 13.Bg5+ Ke8 {Back again!. (RJ)} 14.O-O-O Bxf1 {It's incredibly complicated. Deep Shredder says the best move is Qxh2, a move I hadn't even contemplated. (RJ)} 15.Qxg7? {I thought this was pretty good. But the engine says it's a mistake, picking e5. Incidentally, Black is two pieces and the exchange up, with another White piece en prise! But in this game material is almost insignificant, except in that, if Black can swap off pieces and deaden the game, he has won. White must mate Black before that happens.(RJ)} Qg2 $19 {Aiming to meet Qxh8 with Qxg5ch. Again I was pleased with this, but the computer says it's a bad mistake, with Qxe4 being the move. But it says Black still has the upper hand at -1.6. (RJ) qe4 qh8 kf7 and black is winning [jb]} 16.e5 Be7 17.f4! {A great move, which I had not foreseen. (RJ)} Rxa7?? {The fatal error - completely overlooking White's killer response, which forces mate. I had ironically agonised over this move for as long time; I almost played Bf5, to hold the white squares on Black's kingside. It would have been a much better move, but better still would have been the simple Bxb4, maintaining the upper hand. Chess is just - the moment I forgot about the dynamics of the position and got greedy, my game collapsed. (RJ)} 18.e6! Nh6 19.Qxh8+ Bf8 20.Rd8# {Probably the most interesting game I have ever been involved in. Full credit to Bas - having been sprung with a nasty prepared surprise he kept his cool, threaded his way through the maze of complications and won. Our post-game analysis was even more challenging and enjoyable, with each of us picking up hidden resources and complications at every step. I will add some more analysis at a later stage. (RJ)}
