|
12. d3
|
Giving extra support to c4 and e4, opening the line for the bishop, and finally preventing d3 by black. |
 
|
| |
|
|
12... Kh8
|
Unpinning the f pawn in preparation for my next move. Another possibility would be to get rid of the bishop with 12...Na5 13. Ba2 Be6. |
|
| |
|
|
13. g3
|
Preparing f4? Better would be to continue development with Bd2 or Ne2. |
|
| |
|
|
13... f5
|
Helping to get the light bishop and rook into the game. Also starting a kingside attack, with the f3 pawn as a focus. |
|
| |
|
|
14. exf5
|
Also possible is 14. Bd2 fxe4 15. dxe4, developing a piece, but making the d pawn a passed pawn. |
|
| |
|
|
14... Bxf5
|
Better than Rxf5, since the rook can't accomplish anything on the 5th rank at this point. |
|
| |
|
|
15. Qd1
|
Overdefending f3, but it keeps the queen passive. Better would be developing the bishop with Bd2 or moving the king out of a potential pin with Kg2. |
|
| |
|
|
15... Na5
|
Pushing back the bishop as a defender of d3. |
|
| |
|
|
16. Ba2 e4
|
I thought this simply won a pawn, but I missed white's 18th move. Qg6 first would be better, although it allows 17. b4 Nc6 18. Bc4. |
|
| |
|
|
17. dxe4 Bxe4 18. Bf4
|
Although it wins the exchange for a pawn, it loses the bishop pair, so the positional disadvantages of the doubled pawns and an unsafe king seem to outweigh any material advantage. Kg2 to escape the pin may be best. |
|
| |
|
|
18... Rxf4 19. gxf4 Bc6
|
Intended to keep pressure on f3, but f4 is the easier target. Better would be Bf5 or 19...Bh4 20. Kg2 Qg6 21. Kh3 Bc1 22. Qf1 (Toga thinks Qc1 is significantly worse) Nc4 23. Qxc4 Bf2 (threatening Bf5#) 24. Bb1 Bxb1 25. Rxb1 Qxb1 |
|
| |
|
|
20. Qd2
|
Attacks the knight and defends f4, but better was Qd3 to prevent 20...Bh4 21. Kg2 (21. Kf1 Bb5 22. Qg6 ) Qg6 |
|
| |
|
|
20... b6
|
Protects the knight, but better was Bh4 as mentioned previously. |
|
| |
|
|
21. h4
|
Allowing the rook to get out. Perhaps a better way to do so would be Ne2. |
|
| |
|
|
21... Rf8
|
Attacking f4. Perhaps best is adding more pressure from the passed pawn with d3. |
|
| |
|
|
22. b4
|
Should have failed as described in next move. Better would be Re1 (22...Rxf4? 23. Rxe7 Qxe7 24. Qxf4) |
|
| |
|
|
22... Nb7
|
I missed Rxf4!, which could continue 23. Rh3 Rxh4 24. Rxh4 Bxh4 and the knight can move, 23. bxa5 Bxh4 24. Rxh4 (other moves eventually force white to lose his queen) Rxh4, or 23. Qd3 Be4 and the knight could move after the queen moves. |
|
| |
|
|
23. Kg3
|
Again, Re1 or Rc1 would be a better way to protect the pawn. |
|
| |
|
|
23... Qg6+
|
Pushing the king back. The queen no longer attacks f4 and defends d4, but is otherwise better placed since it has open lines. |
|
| |
|
|
24. Kf2 Bd6
|
Adding an attacker to f4, but better would be activating the knight with Nd6 or preparing Bxh4 with Qh5 (25. Kg3? Rxf4 26. Qxf4 Bd6 27. Qxd6 Nxd6 wins a pawn and queen for the rook and bishop). I also ignored the threat to the d4 pawn. |
