| Once: I don't care for 37. g4. It opens up the king to checks along the third rank and knight checks from f5. It seems much too loosening. Instead how about 37. Qd8+ Kf7 38. Qa8 threatening both the Rb2 and the h7 pawn? White is still losing, but not as quickly as in the game. The amazing thing about Rg2 is how quickly black can construct a mating net around the white king. The king looks perfectly safe on h3. Yet black is able to zap two mating pieces almost instantly. |

| pubplayer: <Once> Unfortunately your suggested 37. Qd8+ Kf7 38. Qh8 (presumably you meant h8 not a8) loses just as quickly to 37...g4+ 38. Kh4 Ng6+. |

| WickedPawn: A beautiful finish by G. García, with whom I had the honor to chat with in 2004 in Montreal in occasion of the Quebec open. He went on to finish second behind Korchnoi. BTW, congratulations Quebec City for its 400 anniversary. The history of North America traces back to July 3, 1608, when S. de Champlain founded the first permanent European settlement which he named Quebec ('where the river narrows' in the Algonquin language). |

| PinnedPiece: Difficult to believe that the sac of the queen on move 22 allowed this finish. Surely white had some major inaccuracies in there. eg. 34 Qd1.
doesn't that permit what follows? |

| patzer2: <Pinned Piece> Black could reach an OK position with 22...Qc5, but chooses instead to "sacrifice" the Queen for an unbalanced position with 22...Nd5!? where he two minor pieces and two pawns and better pawn structure as compensation. I think Black also saw that the isolated White pawns would be difficult to defend, and that as a result he could quickly win a third pawn for full material compensation and winning chances in an endgame. I don't think White lost so much due to an inaccuracy, as the fact that Black from a practical perspective just wore him out trying to hold a position that is very difficult to defend. Was 34. Qd1 a mistake? I don't think so. White might have held on longer by playing 34. Qe4 instead. However, after 34...Rb2 35. Ra8+ Kg7 36. Qe5+ Bf6 37. Qb8 Kg6  , Black still has good long range prospects and White is still fighting to hold the draw. |

| patzer2: The winning moves by Black that caught my eye, were the minor piece fireworks with 35...f5! and 37...Nd5! to set up the hilarious decoy 38...Rg2!! This move carries more than one threat. If the King captures, with 39. Kxg2, then the Knight Fork 39...Ne3+  decides. If White avoids the capture, then he must deal with the immediate mate threat (e.g. 39. exf6? Nf4#). However, after 39. Qf4 Nf4+ 40. Qxf4 gxf4 41. Kxg2 e5  Black has an easily won ending.The biography of GM Lopez, who is a many time Spanish champion and married to Swedish WGM Pia Cramling, is interesting. I wonder if GM Lopez laughed and congratulated the Columbian GM Garcia when he saw the final decisive move of the game (38...Rg2!!). P.S. Maybe we'll see (38...?) as a future puzzle. Might make for a good Wednesday entry. |

| patzer2: With 22...Nd5!? we've probably got a position, where the sacrifice of the Queen for eight points (two minor pieces and two pawns) is even or better compensation. Most often the Queen is valued at nine to 10 points, but it's not a hard and fast rule. So, especially in positions like this, it's worthwhile assessing whether the rule applies or can be ignored to one's benefit. P.S. A move like 22...Nd5!? might make for a good anti-computer strategy! |

| Once: <pubplayer> You're right. Fritz 11 finds that my line loses. 37. Qd8+ Kf7 38. Qh8 g4+ 39. Kh4 Ng6+ leads to a mate in 10 for black. I really ought to check my lines for accuracy (and typos) before posting! Fritz shares my dislike of 37. g4, though, with an evaluation of -1.97. It prefers 37. Qd8+ Kf7. 38. g4 Rxa2 39. gf ef 40. Qd3 with an evaluation of -0.64. An advantage to black, but not resignable. Of course, the monster finds Rg2 in an instant (-4.67). |

| Jimfromprovidence: I like 37 Qd8+ Kf7 38 g4 for white.

| Chessmensch: <patzer2> Am I missing something or do you have a typo? How do you get 39. Qf4? |
|
Jul-03-08
|
| patzer2: <JimFromProvidence> Nice find on 37. Qd8+! Don't know if it holds the draw, but it puts up more resistance than the game continuation, and gives White counter play to make the task of finding a win very difficult for Black. |
|
Jul-03-08
|
| patzer2: <Chessmensch> Oops I did have a typo there. Should have wrote 39. Qd4 (also 39. Qc1 or 39. Qf1), yields a won ending for Black after 39...Nf4+ 40. Qxf4 gxf4 41. Kxg2 e5 . |

| kevin86: A very worthy GOTD! The pieces really fly in this one and the ending move of  g2 is supurb. If the rook is taken,the queen falls by fork,otherwise it is checkmate.White has a sniff after 39  xd5 xh2+! 40  xh2 exd5 and the passed pawns are crushing. |

| Jimfromprovidence: <patzer2> <Nice find on 37. Qd8+!> <Once> also posted virtually the exact continuation. It must have been when I was in the middle of composing my post. |

| Once: <JFP> I think our posts crossed in the ether. I can't claim too much credit - apart from the first Qd8+ the rest of my post came directly from herr fritz. |

| WickedPawn: <DarthStapler: I've played Gildardo Garcia, I drew him in a simul> I also played him in a 40 player simul back in 1991. At some point I was a exchange ahead but I lost on a superb endgame play by GM Garcia. The longer you last against them in a simul, the more time they'll spend with you every move as other people start resigning their games. If you don't have a clear superior endgame, you'll get finished off quickly. |

| Chessmensch: <patzer2> Thanks for the response. That works much better. |

| Magic Castle: White should have captured the Knight when he had the chance. Exchanging the Rook for a Knight and a pawn is not too bad considering that the combination ends with a white tempo. The queenside pawns appear to be white great hope for counterplay. White should have the advantage with a rook and a queen against 2 rooks and an inutile bishop. |

| Jimfromprovidence: I’m surprised no one has considered the very interesting 35 Ra8+.

Now, after the forced 35…Kg7, then 36 Ra7, below, threatening Rxe7, followed by Qd4+. 
click for larger view(35...Bf8 does not work because of 36 Qh5 Ne7 37 Qxg5+ Ng6 38 Rxf8+. If 38…Kxf8 then 39 Qd8+ Kg7 40 Qd4+ skewers black’s rook). Black is forced to play 36…Bc5, again because of the skewer threat Qd4+. White now follows with 37 Qh5!, threatening Rxf7#. Black must play 37…Bxa7. Now, white continues with 38 Qxg5+, securing a draw by perpetual check.

| patzer2: <Jimfromprovidence> After 35. Ra8+ Kg7 36. Ra7, I think Black wins with the incredible 35...Nf6!
click for larger viewFrom here, play could continue 37. Rxe7 g4+ 38. Kh4 Rxh2+ 39. Kg5 Rf2 40. Kh4 h6 41. Qh1 Rf5 with mate soon to follow (42...Rh5# is the immediate threat). |

White might be better off playing in your continuation 38 Qxg4+, but that still puts him down a couple of pawns with a losing endgame. |

| PolishPentium: PP would like to suggest the "desperado" move 39 QxN... If Black takes the Queen, the White king is able to snap up the Rook AND get in position to munch the centre pawn. Then it becomes 3 pawns against three and a good chance of a draw. Contrariwise, if Garcia moves his Rook on move 39, either the b5 or e6 pawn drops, depending on which of the other Black chooses to defend. Again, then, 3 pawns against three, and White with Q against Black's R and N. Again, it seems good for a draw... Of course, since PP is still in possession of his official Duffer's Certificate, there must be a flaw somewhere in his "brilliant" analysis. Would someone kindly point out where he is in error? (^-_-^) |

| Once: <Polish Pentium> 39. Qxd5 Rxh2+ 40. Kxh2 41. exd5 and it's four pawns against two. Black will advance his king to f6 and the white f5 pawn is doomed. White cannot protect it because e4 and f4 are controlled by black pawns and putting his king on g4 does nothing to hold back the passed d pawn. Black also would have ideas of h5 to kick the white king away. For that matter, 39. Qxd5 exd5 40. Kxg2 also wins for black for much the same reason. Now it's only four pawns against three but the black f5 pawn is not long for this world and the passed d pawn is a monster. |
