| Aug-13-11 | | dumbgai: Ah, missed the critical move 69. Qh4+. Hard move to see from the beginning of the combination. |

However, I didn't appreciate the strength of <70.Qh5+>. As a matter of fact, I had such a lack of appreciation, I missed it entirely(!) and hence, went in another direction. :) |

| Aug-13-11 | | sevenseaman: I had replayed this game from Airports Authority Of India tournament not long time ago. Didn't recall the nitty gritty but knew for sure Sasi had won. Qh4+ is the most critical move of the game but I got it only after some intense application of the thinking cap. (The move had struck me as brilliant the first time as well) Rest was routine parade ground stuff. A good POTD. Could throw off anyone with a smug, lackadaisical approach. |

I have a friend S. Davis at chess club. In analysis, he is fearless and works very hard ... is willing to try anything. However, in a tournament (with pressure on, he plays -500 points weaker tahn analysis. Pressure is like that. Hats off to anyone who solved this one ... |

| Aug-13-11 | | LIFE Master AJ: Funny. E-mail today claiming that 70...Ke4; was a mistake, and that Black wins with 70...g4; (as) "White has no checks." Did we miss 71.QxP/g4? |
|
| Aug-13-11 | | LIFE Master AJ: Yes, its check - its also mate, I think. |

| Aug-13-11 | | Nullifidian: Frankly, I didn't find this puzzle very difficult. Obviously, Black is threatening mate in 1, so White's response must be drastic, either a check or some sort of interference. That quickly lead me to 65. ♖e7+
65... ♔h6 is mate in 3: 66. ♕h8+ ♔g6 67. ♕h7+ ♔f6 68. ♕g7# Both 65... ♖f7 and 65...♕f7 end with an exchange of pieces and the passed pawn promoting, though I did analyze an attractive mate in six if Black interposed the rook and then tried playing ♔g6: 65... ♖f7 66. ♖xf7+ ♔g6 67. ♕g8+ ♔h5 68. ♕h8+ ♔g4 69. ♙f3+ ♕xf3 70. ♕c8+ ♔h5 71. ♕xh3+ ♔g6 72. ♕h7# 
click for larger viewSo that leaves 65... ♔f6 and more checks by White.
66. ♕f8+ ♔g6 67. ♖g7+ ♔h5 68. ♕h8+ ♔g4 69. ♕h4+ ♔f3 70. ♕h5+ ♔e4 71. ♕e2+ ♔d4 72. ♖d7. This is the first non-check move, but it's still winning because the queen is pinned. Black has nothing better than to exchange the queen for the rook (or resign). |
|
| Aug-13-11 | | CHESSTTCAMPS: In this tricky queen, rook, and pawn ending, white has a two-pawn advantage plus the move. In view of black's threat of 65... Qg2#, white must work out the coordination of queen and rook with perfect accuracy, or lose the advantage and possibly the game. Fortunately, the black king has very limited options against the white attack and a win is there if white can find it. The obvious and forcing 65.Re7+! is in fact the way to go: A) 65... Rf7? 66.Qxf7+ Qxf7 67.Rxf7+ Kxf7 68.a6 promotes. B) 65... Kh6? 66.Qh8+ Kg6 67.Qh7+ Kf6 68.Qg7#
C) 65... Kf6 66.Qf8+ Kg6 67.Rg7+ Kh5 (Kh6 68.Qh8#) 68.Qh8+! The follow-up must calculated correctly; otherwise, white might play 68.Qe8+(?). Kg4 69.Qh4+! Kf3 70.Qh5+! (Qxh3?? Qd1+ 71.Qf1 Qxf1+ 72.Kxf1 Rxa5 is trouble for white in view of black's superior king position) Ke4 (g4 71.Qxg4#) 71.Qe2+ Kd4 72.Rd7! The pin-skewer setup - a move I might have missed were it not for extensive workouts on the Chess Tactics Server. If the position has not been diagrammed by now, I'll do it in a follow-up post. Qxd7 73.Qd2+ K c4/e4 74.Qxd7 Rxa5 (otherwise the pawn promotes) 75.Qxh3 Black's back-rank mate threats are gone and white has a won ending with Q+P for a rook. Time for review. I expect to win this against Crafty. |

| Aug-13-11 | | CHESSTTCAMPS: <LIFE Master AJ:> <The hardest move for me to spot was 69.Qh4+!.. > Same here - for some reason, I didn't find the continuation immediately and started looking at 68.Qe8+ instead. <If the position has not been diagrammed by now, I'll do it in a follow-up post.> Because it's the final position of the game, I won't bother. The position prior to white's move 72 would make a good Monday/Tuesday puzzle. As the first non-checking move of the combination, it requires a shift of mind-set to find |
|
| Aug-13-11 | | romni: Once you see 65.Re7+, you just have to play it through...(i.e. find as you go!) if that doesnt work then white is lost! As it happens, although 69.Qh4+ is hard to see from the diagram, it works nicely ! |
|
| Aug-13-11 | | rhickma4: I think I must be missing something.
This looks very straightforward.
Black cannot afford to trade of the Q and R, or else the White rook pawn will Queen 65.Re7+ Kf6 66.Qf8+ Kg6 67.Rg7+ Kh5 68.Qh8+ Kg4 69.Qh4+ Kf3 70.Qh5+ Ke4 71.Re7+ Kd4 72.Rd7 wins |
|
| Aug-13-11 | | dufferps: At my level, simply figuring out the winning move after 71. ... Kd4 would be a wonderful challenge. |
|
| Aug-13-11 | | Julian713: Made it all the way to 70.Qh5+, but from there i bogged down and couldn't separate out the various options. Good "survival" puzzle. |
|
| Aug-13-11 | | Marmot PFL: Rd7 was not easy enough for me to find, after all those checks. In playing h3 black is challenging white to find these tactics, and not settle for perpetual, or worse, trade queens, when the rook ending favors black due to white's vulnerable Kg1. |
|
| Aug-13-11 | | Marmot PFL: <for some reason, I didn't find the continuation immediately and started looking at 68.Qe8+ instead.> I think that also wins - Kg4 69 Qe2+ Rf3 (69...Qf3 70 Qc4+) 70 Re7 (threatening Re4+) 70...Kh5 71 Re3 g4 72 Re5+. If so, it somewhat spoils the puzzle, which ideally should have one and only one way to win. |
|
| Aug-13-11 | | Fezzik: I had already seen this game so I knew what to look for. The first few moves were fairly obvious, so the puzzle could have been started after Qh8. |

 | | agb2002: White is a pawn ahead.
Black threatens 65... Qg2#.
The airy position of the black king suggests 65.Re7+, to deliver mate or capture the black queen with a skewer, x-ray or similar: A) 65... Kh6 66.Qh8+ Kg6 67.Qh7+ Kf6 68.Qg7#.
B) 65... Rf7 66.Qxf7+ Qxf7 37.Rxf7+ Kxf7 38.a6 + -.
C) 65... Kf6 66.Qf8+ Kg6 67.Rg7+ (67.Qe8+ repeats moves) 67... Kh5 (67... Kh6 68.Qh8#) 68.Qh8+ Kg4 69.Qh4+ Kf3 70.Qh5+ Ke4 (70... g4 71.Qxg4#) 71.Qe2+ Kd4 72.Rd7 Re5 (72... Qxd7 73.Qd2+ and 74.Qxd7) 73.Qxe5+ Kxe5 74.Rxd5+ Kxd5 75.a6 + -. |

| Aug-13-11 | | abuzic: 65.Re7+ Kf6 66.Qf8+ Kg6 67.Rg7+ Kh5
? which move white to choose: 68.Qe8+, Qh8+ or Rh7+: all win for white, but <68.Qe8+> is the most forcing continuation here: 68.Qe8+ Kg4 69.Qe2+ Rf3 70.Re7! (waiting without check) Qd3 71.Qe6+ Qf5 72. Qxf5+ Rxf5 73.Re4+ Kf3 74.Re3+ Kg4 75. f3+ Rxf3 76.Rxf3 Kxf3. The rest is now clear. |
|
| Aug-13-11 | | Skylark: I think the difficult part of this puzzle was seeing the pin of the g5 pawn, preventing the black king safely escaping onto white's kingside. Without this, it is impossible to continue hunting the black king around the board. I got to that stage and then after the move .. Kf3 I figured "there is probably a win here". I would have played it like that at the board as well, I think. Looking straight at the position, the infiltration following with Qh5+ and Qe2 is relatively straightforward. I am confident I would have played this at the board. |
|
| Aug-13-11 | | Skylark: Out of interest, I only stumbled across the pin on the g5 pawn possibility through the following variation: <65. Re7+ Kf6 66. Qf8+ Kg6 <67. Qg8+!!!!> Kh5 (67. .. Kf6 68. Qg7#, 67. .. Kh6 68. Qh7#) 68. Rh7+ Kg4 69. Rh4+!> Of course, this fantasy of mine was shattered when I realised upon considering my next move after <69. .. Kf3> that <<67. Qg8+!!!!>> blunders a queen (LOL) - however, it did introduce me to the correct idea of Rg7+ and Qh8-h4. So in this instance, following through on a completely rubbish line in my head actually paid off! |
|
| Aug-13-11 | | Patriot: I think most of us would have played 65.Re7+ OTB and let black figure out the next move. I saw that 65...Rf7 loses to 66.Rxf7+ Qxf7 67.Qxf7+ Kxf7 68.a6  . I calculated the game line up to 70.Qh5+ but didn't have time to continue. |
|
| Aug-14-11 | | TheBish: Nice combo! I was on my way to solving it, but started late so decided to start on Sunday's instead. |
