Apr-04-16 | | patzer2: For today's Monday puzzle solution 37. Re6+! clears the way for the decisive advance and promotion of a passed pawn. Black's game takes a sad turn for the worse with 26...g4? 27. Nxg5+ to . Instead, 26...Rg8 keeps Black in the fight. Earlier, instead of the speculative 21...h5?!, the Deep Fritz 15 picks 21...a6 (-1.38 @ 20 depth) or 21...Nf5 (-1.36 @ 20 depth) look to provide Black with good winning chances. |
|
Apr-04-16 | | stst: Divert the Black R, by Re6+, then RxR and the d7 Pawn can promote. Winning is within reach then. |
|
Apr-04-16 | | saturn2: Re6 wins, although the Q+Pawns vs R+Pawns ending requires some more moves. With 1900 elo black should have foreseen the knight fork on g5 (26 th move) |
|
Apr-04-16 | | AlicesKnight: Arguably the most dramatic promotional rook deflection was the one missed by Torre in Carlos Torre Repetto vs Frank E Parker, simultaneous display 1924. The one here is simpler but instructive. |

Apr-04-16 | | gofer: The confusing thing about todays POTD is that we get to this POTD! click for larger viewAt move 37 we have a "Very Easy" win with <37 Re6+> moving into
a "won" Q v R end game.
The problem I have is that two moves earlier we have this POTD. Why play 35 Rxe7+ if we are "hoping" to reach a "winning end game". Surely there is a simpler way to reach a "winning end game" than Rxe7+?  click for larger view<35 ?> |

Apr-04-16 | | Geronimo: An easy puzzle, sure, but also to note here is that white can promote without risk of being put in perpetual check by black's rook. I can't count the number of times I've pushed forward towards a 'winning' gain of material only to find that my loss of tempo resulted in a perpetual check or other forced draw. At least on this puzzle I checked for it before steaming ahead with the game move. |

Apr-04-16 | | goodevans: <gofer: ... Surely there is a simpler way to reach a "winning end game" than Rxe7+?> White missed a quicker win with the simple <35.dxe7>. |
|
Apr-04-16 | | gofer: <goodevans:> Yep, that was my point too... <And after 35.Rxe7+, <35...Kf8> puts up more resistance>. I don't think it really puts up that much more resistance. I think it
ends up in a Q v R end game, but with black having one less pawn! So
that would seem on the face of it to be less resistance... 35 Rxe7 Kf8

Apr-04-16 | | The Kings Domain: Easy puzzle and good game. Nice attacking play by white. I like how he sacrifices a few pawns to gain a good, decisive attack on black's kingside. |
|
Apr-04-16 | | Razgriz: Re6 deflects the rook, white queens, rook can't go on a perpetual check without returning initiative to black in a very open board where his rook and king can be forked. |

The one here is simpler but instructive.> Well spotted! Carlos Torre vs F E Parker, 1924 is a little similar to this game. |

Apr-04-16 | | morfishine: I pulled this off once at the chess club:
<37.Re6+> and the pawn Queens |

|
Apr-04-16 | | Nullifidian: The most obvious forcing move is 37. ♖e6+, followed by 37... ♖xe7 38. ♙d8=♕, giving White a queen vs. rook advantage. Moving the Black king out of check would be worse. |
|
Apr-04-16 | | zb2cr: 37. Re6+ puts Black into a dilemma, with both short lines ably illustrated by <agb2002> and <dfcx>. |
|
Apr-04-16 | | Once: 35. Rxe7+ is not as strong as 35. dxe7, but both win handily. I suspect that white saw a winning continuation and went for it without worrying if there was a quicker or cleaner way. When the clock is ticking (we are on move 35), it can be better to play the safe win than to burn time worrying about other ways of bringing home the point. |
|
Apr-04-16 | | psmith: Wait, it's Monday and there's no Queen to sacrifice... Better sacrifice the Rook then! |
|
Apr-04-16 | | King Sacrificer: <The Kings Domain: …Nice attacking play by white. I like how he sacrifices a few pawns to gain a good, decisive attack on black's kingside.> It looks more like black's blunders turning a won game into a lost one. |

and simplifies further.
< I suspect that white saw a winning continuation and went for it.. clock is ticking... > You are quite right about that. I played a game in which i made a move seeing a mate in 5. Post game analysis discovered a mate in 4. Someone commented "You had a faster mate!" I said "no.. the mate in 5 was faster, because i played it almost instantly!" LOL |
|
Apr-04-16 | | YetAnotherAmateur: 37. Re6+ Rxe6 38. d8=Q Re2+ 39. Kf1 and now white has a decisive advantage. Or 37. Re6+ Kf7/Kf5 38. Rxd6 cxd6 39. d8=Q leaves black in even worse shape. I should point out that you do have to follow the line long enough to ensure that black can't get a perpetual check going, and if white gets greedy and tries to hang onto the h2 pawn with Kg1, then he never gets the chance to bring his newly minted queen into action. |

Apr-04-16 | | whiteshark: Yeah, it's Monday!! |
|
Apr-04-16 | | kevin86: Instead of a queen sac...we have a diversion of a rook to gain a new queen. |

Apr-04-16 | | Longview: <YetAnotherAmateur> Did you mean like this: 35. Rxe7+ Kg6 36. d7 Rd6 37. Re6+ Rxe6 38. d8=Q Re2+ 39. Kg1 Re1+ 40. Kf2 Re6 41. Qxc7 Rf6+ 42. Kg2 Rf7 43. Qd6+ Kf5 44.

There was no time trouble. 35.dxe7 is the TT move. It's obvious. I'm thinking the above position never appeared on the board. Back here White did not play 34.Qxf6+
 click for larger viewWhite played 34.Rxe7+ Kg6 35.Qxf6+ Rxf6
and we get to here.
 click for larger viewThe same position as in the game with the same move number. 36.d7 Rd6 37.Re6+
Now it all makes sense.
Anyone agree, if so I'll send in a correction slip. |
