Here is another Stonewall game, this time against Crafty. Bob made the
comment in RGCC that Crafty's code had been changed to recognize the
pawn
structure. I don't know for sure if the early exchange of pawns made
Crafty not realize what it was getting into. Unfortunately it's not the
latest and greatest Crafty, and it's not running in the fastest hardware
either.

1. d4 Nf6 2. e3 e6 3. f4 d5 4. Nf3 Bd7
{Crafty: 8-> 3:23 -0.07 Bd7 Be2 Nc6 O-O Bd6 Bd2 Ne4 a4
time: 3:45 cpu:100% mat:0 n:3296348 nps:14604
Baldo: Black was out of its opening book after 3. f4. I still
don't understand why the computer likes Bd7.}
5. Bd3 c5 {Baldo: well played. Let's see if Black chooses to
advance the c-pawn, exchange it, or keep the pressure}
6. c3 cxd4 {Crafty: 9 2:47 -0.11 cxd4 exd4 Bd6 Qb3 Qc7
O-O O-O a4 Ne4 Be3
time: 3:11 cpu:100% mat:0 n:2643931 nps:13811
Baldo: so, it chooses to exchange the pawns. This is better
than advancing the pawn, but personnally, I've had more trouble
when the exchange is delayed, and the pressure is increased with
Qb6, Nc6. But the exchange has the advantages of weakening
the d4 and f4 squares. The problem is that it gets rid of the
biggest problem White has with its pawn structure.}
7. exd4 Bd6 8. O-O O-O 9. Ne5 Be8 {Crafty: 9 2:49 -0.19
Be8 Qb3 Qe7 Be3 Ne4 Nd2 f6 Nef3 Bc6
time: 3:12 cpu:100% mat:0 n:2914139 nps:15121
Baldo: Another strange Bishop move. I think Black fears I will
take the Bishop with my Knight. However, the evaluation is
incorrect if it thinks that the B-d7 is worth more than the N-e5.}
10. Nd2 Nc6 11. Rf3 Qb6 12. Kh1 Rd8 13. Rh3 h5 {Crafty:
9 2:34 -0.25 h5 a4 Qc7 Qf3 Rc8 Kg1 a6 Rg3 Qb6
time: 3:08 cpu:100% mat:0 n:3110732 nps:16511
Baldo: This is the first time I've ever seen this move to defend
the Kingside. Normally, g6, h6 are played. But h5 creates a huge
target. The g2-g4 breakthrough will be very strong when ready.
The only reason I can't sac the rook at h5 right now is because I'm
missing one piece to complete the attack and checkmate. }
14. Qe2 Bd7 {Crafty: 8-> 3:01 -0.23 Bd7 a4 Rfe8 Nxd7 Rxd7
Qf3 Qc7 Nb3 a6
time: 3:05 cpu:100% mat:0 n:3054047 nps:16479
Baldo: this is the third time this Bishop moves, and none of these
moves has improved Black's position. As Black continues to waste
time, White amasses its pieces on the Kingside, getting ready
to launch the attack.}
15. Ndf3 Ne7 16. Ng5 {Baldo: the attack is almost ready. The Knight
at g5 is what I needed prior to sacrificing the rook at h5. Crafty
smells something and protects the pawn, weakining its Kingside
even more.}
g6 17. Be3 Be8 {Crafty: 9-> 2:36 -0.46 Be8 Re1 Rc8 Kg1 Nc6 a4
Qa5 Bc2 Qb6
time: 3:05 cpu:100% mat:0 n:3037543 nps:16412
Baldo: fourth move by this Bishop. }
18. Rg1 Bc7 {Crafty: 9 2:43 -0.44 Bc7 Rg3 Nc8 Rb1 Qa5 a3 Nd6
Qf3 Bb5
time: 3:05 cpu:100% mat:0 n:3024719 nps:16276
Baldo: I just find it hard to believe that Black doesn't see the
g2-g4 break coming up.}
19. g4 hxg4 {Crafty: 9-> 6:13 -1.66 hxg4 Nxg4 Nxg4 Qxg4 Ba4
Nh7 f5 Qg5 Rfe8
time: 6:13 cpu:100% mat:0 n:5784850 nps:15488
Baldo: for the first time, Crafty thinks it's in big trouble, as
indicated by the amount of time it takes to make this move.}
20. Nxg4 Nh5 {Crafty: 10 13:36 -5.50 Nh5 Rxh5 f5 Rh7 fxg4
Rxe7 Bd7 Bxg6 Bd6 Bf7+ Kh8
time: 15:46 cpu:100% mat:-4 n:17636174 nps:18629
Baldo: the position was lost long ago. As the position gets worse,
and sees the end nearing, it takes longer to make a move.}
