White's queen-side pawns are a bit inhibited by the black pawn at h5, To do anything on the queen-side becomes a bit slower as a result. IE I have to play a3 before I play b4. I need b4 to play c5 and work on that pawn chain. Also white's king is a bit loose as if I play Bxh3 as white, black plays Qxh3 and now I am probably going to have to do something like f3 to make it harder to pile up on h3, or else Qf3 to get to g2 if black plays Ng4. I don't see any serious plus or minus other than white's somewhat restricted queen-side. Just an opinion. I then tried it on Crafty and Crafty says "nearly even" with a score of -.10 roughly. > > > > > > > > >I evaluated the position as better for black >I assumed in that game that I need the white bishop so I played Bh1 > >It was not a move that I thought much about it because based on previous >experience I know that it is bad to trade the bishop at g2 and I used more time >for other moves. > >I decided to give the position to Fritz and Fritz evaluates it as equal and >likes d4 > >Shredder even prefers the position of white. > >Is this an example for the superiority of computers relative to humans in >understanding positions. > > >[D]r4rk1/1ppq1pbp/3p1np1/p2Pp3/2P5/1PNP2Pb/PB3PBP/R2QR1K1 w - - 0 1 > >Analysis by Fritz 8: > >15.d4! > = (-0.19) Depth: 6/24 00:00:00 115kN >15.d4 Bxg2 16.Kxg2 Rfe8 17.dxe5 dxe5 18.Ne4 Nxe4 19.Rxe4 Qf5 > ³ (-0.31) Depth: 7/23 00:00:00 176kN >15.Bf3! > ³ (-0.28) Depth: 7/23 00:00:00 188kN >15.Bf3 Rfe8 16.Qe2 h6 17.Ne4 Nxe4 18.Qxe4 Qf5 > = (-0.22) Depth: 7/23 00:00:00 219kN >15.Bf3 Rfe8 16.Qe2 h6 17.Ne4 Nxe4 18.dxe4 a4 19.b4 > ³ (-0.28) Depth: 8/24 00:00:00 312kN >15.Qf3! > = (-0.25) Depth: 8/24 00:00:01 345kN >15.Qf3 h6 16.a3 Rfe8 17.Bxh3 Qxh3 18.Ne4 Nxe4 19.dxe4 a4 > = (-0.22) Depth: 8/24 00:00:01 410kN >15.Qf3 h6 16.Bc1 Bxg2 17.Qxg2 Ng4 18.f3 e4 19.fxg4 Bxc3 20.Bxh6 > = (-0.19) Depth: 9/36 00:00:02 927kN >15.d4! > = (-0.16) Depth: 9/36 00:00:04 1435kN >15.d4 Bxg2 16.Kxg2 Rfe8 17.Qf3 h6 18.dxe5 dxe5 19.Ne4 Nxe4 20.Qxe4 f5 21.Qe3 > = (-0.09) Depth: 10/31 00:00:08 3284kN >15.d4 Bxg2 16.Kxg2 Rfe8 17.Qf3 h6 18.dxe5 dxe5 19.h3 Rad8 20.Ne4 Nxe4 21.Qxe4 c6 > = (0.00) Depth: 11/37 00:00:19 7819kN >15.d4 Bxg2 16.Kxg2 Rfe8 17.dxe5 Rxe5 18.Rxe5 dxe5 19.Qf3 Re8 20.Re1 h6 21.Ne4 >Nxe4 22.Qxe4 c6 > = (-0.06) Depth: 12/33 00:00:36 14728kN >15.d4 Bxg2 16.Kxg2 Rfe8 17.dxe5 Rxe5 18.Rxe5 dxe5 19.Qf3 Re8 20.Re1 h6 21.Ne4 >Nxe4 22.Qxe4 > = (-0.03) Depth: 13/36 00:01:33 39735kN >15.d4 Bxg2 16.Kxg2 Rfe8 17.dxe5 Rxe5 18.Rxe5 dxe5 19.Qf3 Re8 20.Re1 h6 21.h3 c6 >22.dxc6 > = (0.03) Depth: 14/41 00:04:45 121046kN > >(Blass, Tel-Aviv 19.11.2003) > > >New game - Junior 7 >r4rk1/1ppq1pbp/3p1np1/p2Pp3/2P5/1PNP2Pb/PB3PBP/R2QR1K1 w - - 0 1 > >Analysis by Shredder 7.04: > >15.Qf3 Bxg2 16.Qxg2 > = (0.09) Depth: 1/5 00:00:00 >15.Qf3 Bxg2 16.Qxg2 > = (0.09) Depth: 1/5 00:00:00 >15.Qf3 Bxg2 16.Qxg2 > = (0.09) Depth: 1/5 00:00:00 >15.Qf3 Bxg2 16.Qxg2 > = (0.09) Depth: 1/5 00:00:00 >15.Qf3 Bxg2 16.Qxg2 > = (0.09) Depth: 1/5 00:00:00 >15.Qf3 Bxg2 16.Qxg2 > = (0.09) Depth: 1/5 00:00:00 >15.Qf3 Bxg2 16.Qxg2 > = (0.09) Depth: 2/5 00:00:00 >15.Qf3 Bxg2 16.Kxg2 c6 > = (-0.05) Depth: 3/8 00:00:00 >15.Qf3 Bg4 16.Qe3 Qf5 > = (-0.03) Depth: 4/10 00:00:00 >15.Qf3 Bxg2 16.Kxg2 Rac8 17.h3 c6 > = (0.01) Depth: 5/13 00:00:00 >15.d4 Bxg2 16.Kxg2 Qf5 17.dxe5 Qh3+ 18.Kxh3 > = (0.02) Depth: 5/13 00:00:00 >15.d4 Bxg2 16.Kxg2 Rae8 17.dxe5 Rxe5 18.Kg1 > = (0.16) Depth: 5/19 00:00:00 >15.d4 Bxg2 16.Kxg2 exd4 17.Qxd4 Rae8 18.Ne4 Re5 > = (0.17) Depth: 6/19 00:00:00 27kN >15.d4 Bxg2 16.Kxg2 Rae8 17.dxe5 Rxe5 18.Rxe5 dxe5 19.f3 c6 20.dxc6 Qxc6 > = (0.15) Depth: 7/19 00:00:00 67kN >15.d4 Bxg2 16.Kxg2 exd4 17.Qxd4 Ng4 18.Qf4 Be5 19.Qf3 Rae8 > = (0.08) Depth: 8/20 00:00:01 192kN >15.d4 exd4 16.Qxd4 Ng4 17.Qf4 Bxg2 18.Kxg2 Be5 19.Qf3 Bd4 20.Qf4 Bxf2 > = (0.19) Depth: 9/21 00:00:03 448kN >15.d4 exd4 16.Qxd4 Ng4 17.Qd2 Bxg2 18.Kxg2 Rfe8 19.h3 Bxc3 20.Bxc3 Ne5 21.Bxe5 >Qxh3+ 22.Kxh3 > ² (0.29) Depth: 10/25 00:00:07 982kN >15.d4 exd4 16.Qxd4 Ng4 17.Qd2 Bxg2 18.Kxg2 Qf5 19.h3 Ne5 20.f4 Nd3 21.Re7 Nxb2 >22.Qxb2 > ² (0.38) Depth: 11/31 00:00:16 2399kN >15.d4 Bxg2 16.Kxg2 Rae8 17.dxe5 Rxe5 18.Rxe5 dxe5 19.Qf3 Ne8 20.Ne4 f5 21.Nc5 e4 >22.Qe2 Qc8 23.Ne6 > ² (0.47) Depth: 12/34 00:00:53 7722kN >15.d4 Bxg2 16.Kxg2 Rfe8 17.dxe5 Rxe5 18.Rxe5 dxe5 19.Qf3 Nh5 20.Qe3 f5 21.f3 f4 >22.Qc5 Bf8 23.Qb5 > ² (0.46) Depth: 13/34 00:01:51 16322kN > >(Blass, Tel-Aviv 19.11.2003)
