11. Qxh5 |
White's plan has been achieved. There are two bishops and a queen ready for a kingside attack. There is a simple mate threat here on h7. Black has to slightly weaken the kingside squares to stop the mate but he should not have any big problems. It is actually the psychological effect of being under attack, which may cause Black to make an error later. | ||||||
| | |||||||
|
11... g6 |
There were two choices here: f5 and g6. Bogart (who had played well up until now) chose the weaker one (g6), and then he also played f5 on his 12th move. Just one move was all that he needed (11. ... f5!). g6 weakens the black squares, and makes it possible for White to put his bishop and queen on black squares near the king (f6 and h6). | ||||||
| | |||||||
|
12. Qh6 |
This move limits Black's options. Black wants to be able to play Nb6 in the future to develop the other bishop on c8. In this position, he cannot do so: 12. ... Nb6?? Bf6 followed by mate. | ||||||
| | |||||||
|
12... f5 |
After f5, Black is surviving and can play the knight to Nf6 or Nb6. | ||||||
| | |||||||
|
13. Rfe1 |
White's new attacking plan: Rf1-Re1-Re7. He cannot mate using the bishops but if he can manage to bring a rook to e7 then he may be able to mate on g7 or h7. | ||||||
| | |||||||
|
13... Nb6 |
Black had two choices: Nb6 or Nf6. It is not difficult to see why Nf6 would have been better. First, it would have blocked the white bishop's diagonal g5-e7. Second, Nf6 might be able to jump to the e4 square for a counter attack. | ||||||

14. Re2 |
Remember the plan was to put a rook on e7. Currently the e7 square is attacked twice with the White rook (e2) and the bishop (g5) but it is also defended twice: with the Black queen (c7) and the bishop (b4). Therefore, in order to seize that square, White must bring a 3rd attacker - the other rook. He may double the rooks with Rae1 next. | ||||||
| | |||||||
|
14... Bd7 |
Black is too passive here and unable to develop the bishop to e6 because of the White rook on e2. By going to d7, the bishop unfortunately blocks the queen off from defending the kingside. It is still better to leave the bishop on c8 so that the queen can control the 7th rank from c7-h7. Here Qf7 or Qg7 would have been better defensive moves. | ||||||
| | |||||||
|
15. Be7 |
After Bd7 blocking his own queen, White does not need the other rook for his plan. He plays Be7 right away, forcing Black to exhange the bishops and bringing the rook to e7. | ||||||
| | |||||||
|
15... Bxe7 |
Bogart is forced to move the bishop from b4 because it has no defender. By exchanging bishops, he will allow Re7 and lose the h7 pawn. He will lose material anyways; he could have lost his material in a better way: 12. ... Bd6!? 13. Bxf8 Bxf8 ... (no more mate threat). He would be an exchange down but, with the bishop pair, he would draw the endgame. | ||||||
| | |||||||
|
16. Rxe7 |
White is now certainly better. The following few moves are all forced. | ||||||
| | |||||||
|
16... Rf7 |
Mate on g7 or h7 was threatened. Rf7 is the only way to stop it. | ||||||
| | |||||||
|
17. Rxf7 |
White will now exhange the rooks and win the h7 pawn. | ||||||
| | |||||||
|
17... Kxf7 |
The Black king is unfortunately moving out into the open and toward the middle of the board. | ||||||
| | |||||||
|
18. Qxh7+ |
Finally, Limbos wins material (a pawn) and threatens to win more (the g6 pawn). The important thing for White now is not to relax. He stands better and he must finish the game off before Black gets a chance. | ||||||
| | |||||||
|
18... Kf6 |
Obviously, Bogart does not want to go to e8 or e6 because of Rae1 . Kf6 protects the g6 pawn but moves closer to the middle of the board where the king can be attacked also by the other White pieces. Kf8 would not have been worse than Kf6. After 18. ... Kf8 19. Qxg6 Re8 and at least Bogart would complete his development. | ||||||
| | |||||||
|
19. Re1 |
Threatening mate with Qe7#. 19. ... Re8 is no longer possible for black because of 20. Rxe8 Bxe8 21. Qxc7 winning Back's queen. | ||||||
| | |||||||
|
19... Qd6 |
Therefore, Qd6 is the only defense here. | ||||||
| | |||||||
|
20. g4 |
With this great move, White is trying to destroy the pawn-cover (g6 & f5) around the Black king. Trying to attack the g6 pawn twice does not bring a quick win: 20. Re3 Be6 21. Rg3 Rg8. | ||||||
| | |||||||
|
20... Rd8 |
By now, Bogart probably does not have any concentration and morale left. Of course, he is losing but with Re8 would have been able to continue the game longer. Rd8? loses right away. Because Bogart cannot take on g4 (Qxg6 mate), Limbos is planning f4 followed by g5# or h4 followed by g5#. | ||||||
