| Mar-15-08 | | GMNick: Mate is coming after Qh4+. |
|
| Mar-15-08 | | Voltaic: good game from Karjako, black's Q skates only along the black squares since move 24. |
|
| Mar-15-08 | | percyblakeney: Karjakin seems to be quite good at blindfold chess, in his first competition in Bilbao he had a bit of a slow start but won 4 of his 5 games in the second half of the tournament. That's 5 wins in his last 6 games now. |

| Mar-17-08 | | notyetagm: Black to play: 42 ... ?
click for larger viewHere the White c3-queen meets the threat of ... ♕d8-h4+ by <PREPARING TO BLOCK> the <CHECK> from h3, i.e., ... ♕d8-h4+ ♕c3-h3. And what does Weteschnik teach us? <OBLIGATION RESTRICTS MOBILTY> <<<The White c3-queen cannot leave the 3rd rank, or else she will not be able to <INTERPOSE> the <CHECK> from the Black queen on h4.>>> Hence this <OBLIGATION> to meet ... ♕d8-h4+ with ♕c3-h3 <RESTICTS> the <MOBILITY> of the White c3-queen to the 3rd rank. <<<So the White c3-queen only -appears- to control squares along the c-file.>>> With this important tactical point in mind, that the White c3-queen neither attacks nor defends any squares along the c-file, Karjakin (Black) struck with 42 ... ♖b6-c6!. Position after 42 ... ♖b6-c6!
click for larger viewKarjakin uses the tactic <REMOVE THE GUARD>: he attacks the White c3-queen defender from a square (c6-square) to which she cannot go and still be able to meet the threat of ... ♕d8-h4+ by <INTERPOSING/BLOCKING> on h3. Hence 43 ♕c3x♖c6??, taking the "free" Black c6-rook, is a horrible mistake that allows a forced mate in 6. |
|
| Mar-17-08 | | notyetagm: (VAR) Position after 42 ... ♖b6-c6! 43 ♕c3x♖c6??
click for larger viewHere is a good calculation exercise: calculate the <MATE IN 6> that begins from the above position with 43 ... ♕d8-h4+ and all the shorter mates in the line. Here is my solution:
43 ... Qd8-h4+ 44 Kh1-g1 (44 Bg2-h3 Qh4xBh3+ 45 Kh1-g1 Qh3-h2#) ... Bf4-e3+ 45 Rf1-f2 Qh4xRf2+ 46 Kg1-h2 (46 Kg1-h1 Qf2-g1#) ... Be3-f4+ 47 Kh2-h1 (47 Kh2-h3 Qf2-g3#) ... Qf2-e1+ 48 Bg2-f1 Qe1xBf1# Here are the mating position in the order they occur: Position after 45 ♔h1-g1 ♕h3-h2#
click for larger viewPosition after 46 ♔g1-h1 ♕f2-g1#
click for larger viewPosition after 47 ♔h2-h3 ♕f2-g3#
click for larger viewPosition after 48 ♗g2-f1 ♕e1x♗f1#
click for larger viewThis exercise is a -terrific- example of a kingside attack powered by an <OPPOSITE-COLORED BISHOP>. It is -remarkable- how completely and utterly defenseless White is in all of these variations on the <DARK SQUARES>. When I saw Karjakin play 42 ... ♖b6-c6!, offering a whole rook(!) just to get in a <CHECK> on h4, I figured that he must have seen a mate on 43 ♕c3x♖c6??. At first I did not believe it, since the White king has two(!) pieces defending him, the White g2-bishop and White f1-rook. But alas these White piece defenders are -powerless- to stop the Black mating attack on the <DARK SQUARES>. A textbook example of a mating attack on the squares of a particular <COLOR COMPLEX>. |
|
| Mar-17-08 | | notyetagm: To reiterate my last kibitz, the variation beginning 43 ♕c3x♖c6?? ♕d8-h4+ is the very -best- example I have ever seen of the power of an <OPPOSITE-COLORED BISHOP> kingside attack. |
|
| Mar-17-08 | | notyetagm: <FRITZ 11> shows that 44 ... ♗f4-h2+ mates one move faster than my given 44 ... ♗f4-e3+. (VAR) Position after 44 ... ♗f4-h2+
click for larger viewSo based on this <FRITZ 11> correction, 43 ♕c3x♖c6?? allows a mate in 5, not in 6 as I suggested. Again, note the -tremendous- attack along the <DARK SQUARES> by Karjakin's queen and <DARK-SQUARED> bishop. |

| Mar-17-08 | | malthrope: <scholes: What happens if 46 .. Kxh6> Sergey's 46... Kh8 is the most precise! (no checks and as <notyetagm> has previously demonstrated mate [and/or winning the Queen] is eminent!). At the very least it made Gelfand resign immediately - it must be good! ~lol~ :) |

| Mar-17-08 | | malthrope: <notyetagm: <malthrope>-<scholes> Have you -ever- seen a better example of an <OPPOSITE COLORED BISHOP> attack?> Hehehe <notyetagm> ;) It's always a treat to see a <BOOC> dominance in the Middlegame or Endgame even! In terms of 'Classic purity' (Q + B vs Q + B with <BOOC>) I've always been quite fond of this one... Reshevsky vs Bronstein, 1953
"Whizz KID" (game of the day May-29-06)
Zurich 1953 · King's Indian, Fianchetto, Classical Variation, 8.e4 (E68) · 0-1 The way in which David weaves his web (creating such beautiful <zugzwang> possibilities) in this classic 'KID' endgame is nothing short of miraculous! :^) All the Best, - Mal |
