| May-14-08 | | Microdot: 34.Re1?? is a very bad blunder from Bu
I think 34.Rf2! is an easy move. |

Cheparinov had the game well in hand but gave a rook away and his huge advantage with 40...Rxh3??, instead of 40....Re8 below.

click for larger viewIt’s difficult to believe, but this position is a forced win for black. After 44 Qxf3 Qxf3 45 Rf2 Qxf2+ 46 Kxf2 f1Q+ 47 Kxg1 Kf6 Black’s king eventually gets to capture white’s d pawn and is then able to promote his own d pawn.

Both 40...Rxh3! and 40...Re8! was winnig.
In my opinion as a chess player 40...Rxh3 was very beautiful win. |

| | Jimfromprovidence: <microdot> Please look at the position once more. 40 ...Rxh3 loses a rook. 40...Re8 wins immediately. |
|
| May-14-08 | | Microdot: Dear Jim,
I agree you, 40...Re8 was an easy win but 40...Rxh3 was also %100 wining and in my opinion 40...Rxh3 was a more beautiful and fantasy win. |

| May-14-08 | | euripides: <Jim> I don't see how White avoids immediately returning the rook after 41.exf8+ Kxf8. Black threatens Rh1 mate and any queen move seems to allow f2+ Qxf2 Rh1+ Kxg2 Rh2+ . |

| May-14-08 | | euripides: After <40...Re8> can White try 41.Kh2 ? It feels odd to put the king in harm's way and I imagine Black's winning but I don't immediately see a clean kill. One line is 41...g1=Q+ 42.Rxg1 Rxg1+ 43.Kxg1 Qc1+ 44.Kh2 Qxa3 45.Qg3+ Kf7 46.Qf4+ and BLack has to calculate whether he can escape the checks. |
|
| May-14-08 | | euripides: <Jim> my point was that since White in the game immediately returns his rook -and apparently has to - it doesn't make sense to say that 40...Rxh3 'loses' a rook. |

| | Jimfromprovidence: <euripides> <my point was that since White in the game immediately returns his rook -and apparently has to - it doesn't make sense to say that 40...Rxh3 'loses' a rook.> I meant black loses an equivalent amount of material. If white had played properly after 43...Kf7, he would have forced a queen for rook exchange. |
|
| May-14-08 | | euripides: <Jim> I see what you mean. 40...Re8 does seem to be a simpler win. |

| | Jimfromprovidence: I don’t quite get it, but after looking at a couple of videos of this match, the conventional wisdom seems to be that 40…Rxh3 for black was perfectly fine and winning. GM Joel Benjamin narrated an instructive (extensive) video of the match. The link is below. http://webcast.chessclub.com/Mtel08...

| May-14-08 | | Andrew Chapman: If 43.Qxg2 I think black does not play Rg3 because of Rf1, but instead Qxd4+ Kh1 Qh4+ Kg1 and then Rg3. |
|
| May-15-08 | | Gilmoy: A lovely duel of outposts. Bu plants his N on b7 and f7, but Cheparinov outdoes him with the wacky QB tour Bc8-d7-e8-h5-f3. Bu's N chased down the B like Achilles pursuing the Tortoise, but that gave Chepa just enough tempi for the h-pawn assault, which looks like one too many complications for Bu to solve in time pressure. |
|
| May-15-08 | | Landzhev: After the game Ivan said he disliked white's opening play, and for that matter, the whole Nf3-d2 idea: "It becomes a Stonewall, but in a much better version for black - black achieves everything: Qh4, g7-g5. Just too much tempi ahead". |
|
| May-15-08 | | euripides: <Land> Interesting. Bu seems to like these slow approaches to d4 openings: Bu Xiangzhi vs Radjabov, 2008 |
|
| May-15-08 | | ajile: Black gets a good version of a Dutch Stonewall by transposition. Very passive and uninspiring play by White. Looks like White is playing for a draw to me. |
