| Patriot: It's nice to see things instantly sometimes. 43...Qh1+ 44.Rxh1 Rxh1#. But it may not be so easy to see with mere seconds left and adrenaline coursing thru the vains. I wondered why 41...Rb1 wasn't played. But it's clear now that 41...Rb1 42.Qxe4! Qxe4 43.Rxb1 Qxb1? 44.a8=Q. The game is still in the air since black has the powerful b-pawn so it could be drawish, or it could be winning with some care. I agree with Hansen's 41...Rd3 because now if 42.Qc4 (with the previous idea in mind) then 42...Rxe3! is devastating (43.fxe3 Qf2+ and mates). 43.Qxe4 Qxe4 44.fxe3 Qc2+ (44.Ra1 Qa8 45.fxe3 b3  is probably simplest) 45.Rg2 Qa4 . |

| Domdaniel: Once's 40.Qf4 does in fact draw. But to go back a couple of moves ... I have no doubt that Black 'saw' 38...Rb1. It's the obvious culmination of his attacking plan. The trouble is that it allows White to play 39.Qd8+ Kh7 40.Qxd5 exd5 41.Rxb1 ... when it is not a simple matter for the Queen to win against rook and bishop. So Black played the preparatory ...Kh7 to avoid back-rank checks. Plausible, but a mistake, letting the White Queen return to d4 and f4, after which there's no way through. Instead, however, Black could have played 38...Be4! - the same blocking mechanism actually used in the game a few moves on. This wins. The fact that it leaves e6 hanging is irrelevant, as white needs to hold onto the *dark* squares around his king - not just the obvious light ones - to survive. For instance, any line where Black can play ...Rxe3 or ...Rxf2 wins, unless the queen can recapture (or at least support the Be3). So an attempt to exchange queens on the light squares, like 38...Be4 39.Qxe6+ Kh7 40.Qg4 loses to 40...Rxf2+ and mate in 3. Once [sic] White missed the drawing line 40.Qf4, Black found the blocking idea ...Be4. I'd guess that both were in time trouble. |

| David2009: <al wazir: Van Wely loses again. Sometimes it seems as if <chessgames.com> is going out of its way to make him look bad.> No it's just that Van W.
produces such entertaining games - he takes risks to win even (especially?) against stronger players. But he's not just a swashbuckler: check out Van Wely vs Short, 2010 |

| MaczynskiPratten: How many other games are there where the winner is two Queens down at the end? Answers on a postcard (or this forum) please. Interesting game, lots of good comments, particularly nice contribution from <Once> with some really meaty analysis to add to the usual entertaining storyline. 41...Rd3 would make a good later-in-the-week puzzle because of its subtle but vital advantage over 41...Rb1, as <Patriot> points out. |

| David2009: Here's the position in Van Wely vs C Hansen, 1992 with White to play move 40 (the last diagram in <Once>'s entertaining, informative and instructive post)
click for larger view
There's a clear difference of opinion between <Once> and <Domdaniel> who believe 40 Qf4! will draw and <LIFE Master AJ> who thinks <White was simply outplayed ... the ending with the opposite-colored Bishops (plus heavies) was lost for White, he should have never allowed the Black e-pawn to advance and clear the diagonal.> Which distinguished kibitzer is right? As usual I try to bottom the question by feeding the position into Crafty End Game Trainer, http://www.chessvideos.tv/endgame-t... the ending will be very difficult to defend. Playing against Crafty EGT, the first few moves are forced: 40.Qf4! Qxf4 41.gxf4 (if Bxf4? Ra3! wins easily) Ra3 42.Bc5! Ra4 43.a6 b3 to give
click for larger view
First time I had this position I continued 44. a7? and lost quickly to a mating attack 44...b2! 45.Rb1 Ra1! 46.Rxb2 Rh1+ 47.Kg3 Rg1+ 48.Kh4 g5+ 49.fxg5 hxg5+ 50.Kh5 Bf3#. Back to the drawing board (the second diagram). Sacrificing the a Pawn with 44. Kg3 is clearly hopeless. Second time round, I retracted 43.a6 b3 playing instead 43.Rb1 b3 44.Bb6 Kg6 45.Kg3 Kf5 46.f3 Rxf4 and my Pawns fall like ripe fruit. At this stage I have to say my money was heavily on <LIFE Master AJ> as being right. HOWEVER... The puzzle is: White to play and draw against the EGT from the second diagram. Think of it as an Insane Sunday puzzle. Or do you want to go back and improve White's earlier moves? [To be continued] |

| Fezzik: Wow! van Wely allowed himself to get mated rather than resign? What was the time control? |
|

| Patriot: <(44.Ra1 Qa8 45.fxe3 b3 is probably simplest)> Correction: 44.Ra1 Ra3 is best. I'm not sure what I was thinking there. |

| Old Wolf: Haven't checked with computer but 41..Rb1 looks to fail the same way as 40..Rb1 did: White plays QxB! and collects the rook. I would suppose Van Wely saw all this and figured that he could safely play a7 because Rb1 didn't work; but he overlooked Rd3! which chases the queen away from being able to capture the bishop in response to the black rook going to the back rank. |
|
| Nov-08-10 |
| Old Wolf: Actually I think this game would have made for an excellent problem later in the week, to find Black's 40th move. ..Be4! is brilliant because the white queen is overloaded: it has to guard e3 (otherwise Rxe3 wins) and it has to cover the white bishop (otherwise Rb1/Rd1 etc. wins). After ..Be4 White can do nothing to prevent ..Rd3 chasing the queen away from one of those defensive points. |

| vivek priyadarshan: What about 34.f4 ? Why allow black queen enter on f3. |
|
Nov-08-10
 |
| Sastre: If 34.f4, then <34...Qh5 35.Kf2 Qf3+ 36.Ke1 Qxg3+ 37.Kd2 Qg2+ 38.Ke1 Qxh3>, which looks good for Black. |

| TheBish: Van Wely vs C Hansen, 1992 Black to play (43...?) "Very Easy"
I often don't bother to comment on Mondays, because they are so easy, but this one is too fun to ignore -- I love this tactic! 43...Qh1+! 44. Rxh1 Rxh1#. |
