19. Bd3
|
Getting the bishop off the back rank, defending c2, and (most importantly) connecting the rooks. |
 
|
| |
|
|
19... Rb6
|
Threatening to double rooks... |
|
| |
|
|
20. Rhe1
|
Of course not 20. Qxa7? Rxb2 winning the queen. |
|
| |
|
|
20... Qf4 21. Qxa7
|
This is okay now, although perhaps Qa3 was safer (see the next note). |
|
| |
|
|
21... Rcb8
|
A weak attempt at an attack -- I had found the sacrifice Rxb2 , where after 22. Kxb2 Rb8 , black has mating threats, for example, 23. Ka1 Qd4#, 23. Ka3 Qb4#, 23. Kc3 Qb4#. White must find the very difficult return-sacrifice 23. Bb5! to be able to defend sufficiently. |
|
| |
|
|
22. b3
|
Easily blunting black's threats. |
|
| |
|
|
22... Rb6b7 23. Qe3
|
Offering a queen exchange. This move is alright, but black has an answer... |
|
| |
|
|
23... Qa4
|
Oh no! I saw ... Qxh2 24. Rh1 winning for white, but this move is much better for black. With four pieces attacking b3 and only two defending, white has to defend accurately against mate! |
|
| |
|
|
24. Be4
|
A good move that should allow white to hold on. Black could win the queen and all of white's kingside pawns by forcing exchanges on b3, but with no support in the endgame, the two rooks and bishop will overpower the lone queen. |
|
| |
|
|
24... Rb7b4
|
A weak move to remove the threat on the Rb7, as Ra7 was more threatening. |
|
| |
|
|
25. Qc3
|
Another good defensive move, which also grabs control of the long diagonal. |
|
| |
|
|
25... Rc8 26. Qb2
|
Staying on the long diagonal, and adding the threat of bxa4. |
|
| |
|
|
26... Qa7 27. Rd2
|
Disallowing Qf2 and threatening Re-d1 and Rd8 . |
|
| |
|
|
27... Qb8 28. Red1 h5
|
If white can entice either the Rc8 or the Qb8 away from the defense of the d8 square, Rd8 still leads to mate. h5 accomplishes nothing, and it appears that black is playing without a plan, hoping for white to slip. |
|
| |
|
|
29. Bc6 Bf5
|
Rxc6 is impossible due to 30. Rd8 Qxd8 31. Rxd8 Kh7 32. Qh7# |
|
| |
|
|
30. Bd7
|
Forcing an exchange, bringing white closer to a won endgame. |
|
| |
|
|
30... Bxd7 31. Rd2xd7 e6
|
e6?? A very bad move. Black now has no good defense against the coming white counterattack. Remember white's 25th put the queen on the long diagonal? This comes back to haunt black now... |
|
| |
|
|
32. Qf6
|
Threatening Qxf7 leading to mate, and also threatening Rd8 , leading to a Queen vs. Rook ending for white. |
|
| |
|
|
32... Rf8
|
Defends against the first threat, but there is no defense against Rd8. |
|
| |
|
|
33. Rd7d8
|
Black resigns. Black is helpless to prevent white from exchanging two rooks for rook and queen. |
