|Mar-29-18|| ||stst: Looks easy to me...may overlook though:
The focal point is whether the c6 pawn can promote: just try:
9.RxP (a7) IF (A) RxR
10.c7 promotion can only be stopped by K, so Kd7
11.PxN=Q ... rest easy
But if 9. .... IF (B) BxP
10.RxR Nd7 to guard RxN
11.Ne5 sets Black almost zugwzewang?? exchange also profits White only.
|Mar-29-18|| ||FSR: This version was never played, and bears little resemblance to the actual game, Schlechter vs J Perlis, 1911.|
|Mar-29-18|| ||Mayankk: Whatever be the history of this game, the solution to this puzzle is cute and am glad to find it.|
Having missed a rather simple Wed puzzle, this is such a relief!
|Mar-29-18|| ||Cheapo by the Dozen: This one was really fun -- and pretty easy for a Thursday.|
The key to solving for me was seeing:
-- The opportunity was in the pawn.
-- White didn't really have a lot of lines of attack ... but the a-file was begging to be somehow exploited.
|Mar-29-18|| ||Steve.Patzer: As stst mentioned, 9. Rxa7 should be followed by Bxc6.|
|Mar-29-18|| ||Once: Sometimes a simple pawn can make a knight look stupid. |
The key to today's puzzle is that the pawn on c7 is threatening to force a coronation on either b8 or c8. Black can prevent either one, but he can't prevent both. If the Nb8 moves, white plays c8=Q+. If Black covers c8, then white plays cxb8=Q.
The immediate 9. c7 doesn't work because black can play 9...Nc6 and the rook covers the queening square.

So 9. Rxa7 to deflect the rook from the back rank. Now the queening trick works.
|Mar-29-18|| ||saturn2: I saw 9 Rxa7 Nxc6 (RxRa7 is not possible) 10 RxRa8+ Kd7
and white has more material.|
|Mar-29-18|| ||AlicesKnight: 9.Rxa7; if .... Rxa7 then 10.c7 queens on c8 or b8. If not then the R goes. Either way White is material up. Is this a 'variation' rather than the game itself?|
|Mar-29-18|| ||agb2002: A bit famous, real or not.|
|Mar-29-18|| ||morfishine: I love this theme with the advancing pawn and the inability of the Knight to stop it: <9.Rxh7> 9...Rxh7 <10.c7>|
Set'm up again Sam
|Mar-29-18|| ||malt: <agb2002> A bit famous,|
9.R:a7 R:a7 (9...N:c6 10.R:a8+ )
10.c7 Nc6 11.c8/Q+ Nd8 12.Ne5
Not sure if were real or not.
|Mar-29-18|| ||sjunto: I got a Thursday puzzle!|
|Mar-29-18|| ||catlover: After botching yesterday's fairly easy Wednesday puzzle, it was nice to get this one.|
|Mar-29-18|| ||mel gibson: I wish I would have looked a bit longer -
I might have seen that move.

|Mar-29-18|| ||BOSTER: <sjunto:I got a Thursday puzzle>.
I did not.|
|Mar-29-18|| ||Pasker: Found it easily. I have seen this tactical motif a lot of times before. The tactic is push a pawn to the 7th rank while simultaneously attacking a knight (only knight works) so the pawn can promote in two different ways, one is to capture the knight and if the knight moves then move straight up so both of these threats cannot be stopped a forces a new queen. In this case its not possible due to the rook hence RXa7!! deflecting the rook.|

|Mar-29-18|| ||jrredfield: Got it but it probably took me four minutes at least. I spent too much time looking at knight moves.|
|Mar-29-18|| ||SpamIAm: Here's a game where the theme actually happened. Play out the whole game, it's worth it.
Winz vs Czerniak, 1939|
|Mar-29-18|| ||Jonathan Sarfati: <SpamIAm:> You mean V Winz vs M Czerniak, 1939, where the "victim" allowed it and just ignored the rook to win.|
|Mar-29-18|| ||Jonathan Sarfati: Lightning struck twice in the same place 80 years apart: Ehlvest vs Illescas Cordoba, 1991|
|Mar-29-18|| ||takchess: Interesting enough this exact position is listed in Ct-art 1591 level 3 as Komoltsev Arjanov Alma-ata 1964. I have solved it correctly in Ct-art but not here. .......|
|Mar-29-18|| ||SpamIAm: You got it, Jonathan.|
|Mar-29-18|| ||gawain: This has to be one of the weirdest winning combinations ever. Love it!|
|Mar-29-18|| ||RKnight: <Steve.Patzer> said "As stst mentioned, 9. Rxa7 should be followed by Bxc6."
No, that does not work: 9...Bxc6 10. Rxa8 N(6)d7 11. Ne5 wins.|
