Another GM beats e4stat

E4stat played in the Philadelphia Open. I won a prize and gained a few rating points, but it was not because of this game. GM Bryan Smith gives a lesson on how to beat 2100 players; hopefully you can learn something from this.

White can double on the f-file, swing the rook over to d2, or play Qh5 without dropping the c2-pawn. But these plans are too slow. Stockfish recommends 17.Nd4.} Nc5 18. Rd2 {Preventing ...d5} ({ After the game, I thought that} 18. Nd4 { was more accurate, but in my notes I realize that} d5 19. e5 Ne4 { is still miserable for White}) (18. Nb5 Qb8 19.

White from playing c2-c3 in some variations}) 19. e5 $6 ({ I saw his trick:} 19. exd5 $6 Nxb3 20. cxb3 Bc5 $1 { and Black regains the pawn favorably.} 21. Bxc5 Qxc5+ 22. Kh1 Nxd5 23. Nxd5 Bxd5 24.

Instead, it thinks that Black should meet 20.e5 with 20...Nxb3 followed by ...Ba6, with a slight advantage.}) 20... Nba6 21. e5 (21. exd5 Nxb3 22. Qxb3 Bc5 $1) 21...

Nc6 $1 {is a much simpler refutation}) 24. Rd3 { leads to some very entertaining variations:} Qxd3 25. Qxd3 Nxa1 26.

Rd4 {picks up the b4-knight, but if Black plays 23...Ba6, then it's clear that White is just setting traps}) 23... Ba6 $6 {A natural move that I passed over in my notes} ({Stocky prefers} 23... a5 $1 {The point is that after} 24. Qe1 Qxf4 25. Rd4 {, Black's knight is protected. So White can't save his f4-pawn and his position collapses.}) 24. Nxa7 $4 {I felt like I was almost in zugzwang.

Rad1 {Stocky's move. My notes originally suggested 26.Bf1, but then I noticed that 26...Qxf1+ was strong. White has lost a pawn, but he has a firm grip on d4 and he has mostly sealed up the holes in his position.}) 24... Ra8 $1 { I missed this idea. I thought he was going to double on the c-file} 25.

Of course it shouldn't work, but you have to create opportunities for your opponent to go wrong}) 28... Qc5 $1 (28... Qxf3 $2 29. Bxf3 {will be much harder to win. White will withdraw the knight to the wonderful d4-square.}) 29. Qxd3 Qxc6 30. Rd1 Rac8 31. Kg1 (31. f5 Qc2 { and White's "attack" is not going anywhere}) 31... Qc2 32. Qxc2 Rxc2 33. Bf1 Rec8 34.
