[Event "BCC Championship "] [Site "BCC"] [Date "2016.04.14"] [Round "2"] [White "Michael Tausz"] [Black "Peter Lumsdon"] [Result "0-1"] [WhiteElo "1433"] [BlackElo "1786"] [ECO "B21"] [Opening "Sicilian: Smith-Morra Accepted"] 1.e4 c5 2.d4 cxd4 3.c3 dxc3 4.Nxc3 d6 5.Nf3 Nc6 6.Bc4 e6 7.O-O Be7 8.Qe2 a6 9.Rd1 Qc7 10.Bf4 Bd7 11.Rac1 Rc8 12.Nd5?! {MT: The Knight was itching to jump into the fire, but it turned out too optimistic and premature! My thoughts were: I am ahead in getting my pieces out, have possibilities on the c-file (which hopefully displaces his Queen) and can open the e-file while his King is still stuck in the middle. The pawn on d6 seems quite weak, too. Still somehow looks good to me, though, but obviously that's not enough. The Knight on g8 looks stuck, but it actually defends e7 very well. Note to self: More and better calculation needed!} exd5 13.exd5 Na5! {MT: I thought this was the best defence. The analysis engine on this site actually recommends Na7 and sees it as -1.5 then! On the game continuation however, the engine ends up (after thinking it was at least -1.5 for quite a while) on -.0.088 - so thinks there is enough compensation! The engine line is actually exactly what we played over the next moves!} (13...Ne5 14.Nxe5 dxe5 15.Bxe5 Qb6 16.Bxg7 {was one of the lines that lured me into playing the knight sac.}) 14.Bxa6 Qb6! {MT: because of poor calculation I underestimated this move. I mainly reckoned with Qb8 or Qd8 and thought both are rather good for White. Not that I saw the following lines in any detail...} (14...Qb8 15.Bb5 Rxc1 16.Rxc1 Bxb5 17.Qxb5+ Kd8 18.Qxa5+) (14...Qd8 15.Bb5 Rxc1 16.Rxc1 Nf6 17.Bxd6 Nxd5 18.Bxe7 Bxb5 (18...Qxe7?? 19.Rc8#) 19.Qxb5+ Kxe7 20.Rd1) 15.Rxc8+ Bxc8 16.Bb5+ Bd7 17.Bxd7+ Kxd7 18.Nd4 {MT: Was Rc1 or Qc2 better?} Nf6 19.Nf5 Bf8 {MT: looks ugly, but g7 was hanging as well.} 20.Re1 {MT: The attack seems to fizzle out. Maybe something like} (20.Bg5 Qa6 21.Qf3 Nc4 22.Qh3) 20...Qa6 21.Qc2? {MT: After the game, PL thought this was the decisive error. I agree as once the queens are off there is not enough left to continue the pressure.} (21.Qf3 {MT: but I still cannot see a convincing continuation from here.}) 21...Qc4 22.Qxc4 {MT: If I try to keep the queens on with Qd2, d5 falls anyway first. But probably still better.} Nxc4 23.b3 {MT: game pretty much over here...} Nb6 24.Kf1 g6 25.Nd4 Nfxd5 26.Bd2 Bg7 27.Nf3 Bc3 28.Bxc3 Nxc3 29.a4 Nbd5 30.Ng5 f6 31.Ne4 Nxe4 32.Rxe4 Re8 33.Rxe8 Kxe8 34.Ke2 Kd7 35.Kf3 Kc6 36.h4 Kc5 37.g4 Nb4 38.Ke2 Kd4 39.Kd2 d5 40.f4 Nc6 41.Kc2 Ke3 42.g5 fxg5 43.h5 Ke2 44.hxg6 hxg6 45.fxg5 d4 {MT: In some way a nice game, but I guess the lesson for me is: Don't play such speculative sacs against a better player, especially if you cannot calculate them properly! PL's defence was way too good for me.} {#R} 0-1
