|Jun-20-06|| ||gulliver: Why did white resign?|
|Jun-20-06|| ||gulliver: I see it.|
|Jun-20-06|| ||tamar: <gulliver> Black wins the knight on f1 and then the pawn on f2 after which he has two connected passed pawns.|
48 Kd2 Rxf1 49 Rxf1 Qxf1
|Jun-20-06|| ||gulliver: < tamar> Another way the game might have continued: 1.Rc7+ Kh6 2. Kd2 Rxf1 and the white rook on c7 cannot capture b7 pawn because of the fork: Qxd5+|
|Jun-20-06|| ||tamar: Very impressive game by Mamedyarov. By the end of the game, it no longer looks like a Bishop's Opening, but a King's Indian where everything went right for Black.|
|Jun-20-06|| ||gulliver: What's the point of 42.. Qf4 ? Why not play right away 42...Rxh3 ?|
|Jun-21-06|| ||gulliver: I made an error in my last comment. I meant not 42..Rxh3 but 42.. Nxh3.|
For example: 43. gxh3 Qg5+ 44. Kh2 Qf4 + and white is in deep trouble.
At Chessbase site, GM Mikhail Golubev commented on this game the following: "Black finished the game by direct attack, which was prepared by the brilliant move 42…Qf4!. "
|Jun-21-06|| ||gulliver: Can someone explain to me what's so brilliant about 42.. Qf4|
|Jun-21-06|| ||tamar: <gulliver> After 42...Qf4 White has no constructive moves. The one he picks 43 Rc1 gives the King an escape square, but ends up weakening the f pawn, which makes 43...Nh3+ more decisive.|
Perhaps it is this switch from attacking play to a Petrosian-like smothering move that made Golubev call it brilliant.
42...Nh3+ 43 gxh3 Qg5+ 44 Kh2 Qf4+ right away might work, but I don't see anything other than 45 Kg2 Rxh3 46 Kxh3 Qg4+ 47 Kh2 Qxe2 48 Qc3 with some hope of saving the game.
|Jun-21-06|| ||gulliver: <tamar: "42...Nh3+ 43 gxh3 Qg5+ 44 Kh2 Qf4+ right away might work, but I don't see anything other than 45 Kg2 .." >
I still cannot see what difference does 42 .. Qf4 does. For white could have played the same defence as you showed above ( 45. Kg2) in the game, so what is the difference ?. [White preffered to move his king to f1 and lost. ]|
|Jun-21-06|| ||tamar: Black's attack is more drastic after 42...Qf4. If White tries the same defense, fleeing to h2 instead of f1 the following position arises:|

Now Black can play 45...Rxh3+ 46 Kxh3 Qg4+ winning the Rook on e2, but because of the absence of the f1 rook he can win instantly with
45...Rxf2+! 46 Rxf2 Qg3+ 47 Kh1 Qxf2 and mate can only be averted by heavy material loss.
|Jun-22-06|| ||gulliver: <tamar> If white plays 43. Qc2 than 43.. Nxh3 44. gxh3 Rxh3 45. f3 [ 45. Rc1 Qg5+ 46. Kf1 Rh1 # ] Qh4 and mate on h1 follows.|
The idea is that after 43. Qc2 Nxh3 44. gxh3 Rxh3 black threats mate with both 45...Qh2 # ; and 45.. Qg5 # ;
The idea behind 42... Qf4 is therefore to control the h2 square , inhibiting the movement of the white king . For ex: After 43..Nxh3 the white king cannot move to h2 and taking the knight becomes the only rational move. In addition, the control of h2 square is important also in the lines I analyzed above with attention to the queen manuevere to h4 via f4 on the 1st line of 45. f3 or the mate threat on h2 described in the paragraph above [ 45..Qh2 #] . I think I underdastand much better now the value of the queen move to f4 and why it was called abrilliant move by GM Gobulev
|Jun-22-06|| ||gulliver: < tamar: Perhaps it is this switch from attacking play to a Petrosian-like smothering move that made Golubev call it brilliant.>
Yes. Its like Mamedyarov took a pause in the middle of his direct attack and played 42.. Qf4.
This queen move upgrades his position. The geniosity of the move has both tactical and positional facets.
Petrosian came to your mind and apropriately so.|
