| Dec-07-16 | | Once: You can't take my rook because I have this pawn promotion trick. Oh yes I can take your rook because I have this little pawn deflection trick. Tricky little blighters, pawns. I'll admit it. After the shenanigans of monday and tuesday, I checked, double checked and triple checked my solution today. Yesterday they gave us an obvious move that wasn't. Today they gave us an obvious move that was. |

| Dec-07-16 | | gofer: This finish is a little too famous. But still, with my limited memory, I had to work it out... 35 Kxd5 d2
36 g4+ Kxg4
37 Rc4+ Kf3
38 Rd4 Ke2
39 b6 
White's b pawn will promote! |

| Dec-07-16 | | mel gibson: Nice ending.
It's well explained above. |
|
| Dec-07-16 | | zb2cr: I found this. The explanation by <YouRang> is particularly good. Well done to <YouRang>! |
|
| Dec-07-16 | | TrollKing: Wow. Just wow. |
|
| Dec-07-16 | | catlover: Even though I didn't find the key move 36 g4+, I found this a fun and instructive puzzle. |
|
| Dec-07-16 | | patzer2: Perhaps I missed today's Wednesday solution 35. Kxd5 d2 36. g4+! Kxg4 (36...Kf4 37. Rc4+) 37. Rc4+ Kf3 38. Rd4 Ke2 39. b6 because it involved consecutive "bouncing checks," which in the real personal finance world is a bad thing. Of course in Chess, as in today's problem (35. ?), consecutive "bouncing checks" can be a good thing. The losing move for Black looks to be 30...Ke6? allowing 31. Ra6+ Kf5 32. b5 (+2.37 @ 33 depth, Stockfish 080916). Instead, 30...cxd4 31. Rxd4 h6 32. Rxd4+  (+1.07 @ 28 depth, Stockfish 040916) gives Black practical drawing chances. Earlier, Black might have improved with 18...0-0-0 19. 0-0-0 20. Nxc3 = (0.00 @ 35 depth, Stockfish 7). |

 | | keypusher: That was funny. I saw the rook was hanging, and then I spotted the g2-g4+ idea, so I spent a lot of time trying to figure out a win after 35.g4+ followed by Kxd5. It works if Black does something really stupid, but not if he plays 35...Ke5. Finally it dawned on me that I could take the rook first, and <then> play g2-g4+. |

 | | Honza Cervenka: Quite funny thing is that I saw the winning idea almost instantly but somehow I dismissed to take the Rook at first starting with 35.g4+, and then I spent some twenty minutes by trying to find a win in the line 35.g4+ Ke5 (or 35...Ke4 36.f3+ Ke5 etc. - all other moves are losing the game) 36.b6 d2 37.b7 d1=Q 38.b8=Q+, and only then I have realized that 35.Kxd5 d2 36.g4+ simply avoids all this mess with Q+R.:-) |

| Dec-07-16 | | dfcx: White must gain a tempo to win the rook and preventing black pawn from promoting. 35.Kxd5 d2
36.g4+ Kxg4/Kf4
37.Rc4+
followed by Rd4 wins for white. |

| Dec-07-16 | | Herma48852: Could not find the right move order for this beautiful end game combo. Great puzzle! |

Just ran across this You Tube of 15 yr old Bobby Fischer on I've Got A Secret. Skip to the 17 minute mark:

Move 36 with white to play with black's g pawn absent.

|
| Dec-07-16 | | YouRang: <Jimfromprovidence> Very good side puzzle! :-) I got it, but only after stumbling down some "wrong pawn" lines. |
|
| Dec-07-16 | | Marmot PFL: Stared at this for 3 or 4 minutes this morning then saw the solution in 15 seconds this afternoon. |
|
| Dec-07-16 | | FairyPromotion: <Jimfromprovidence> Thanks a lot! I knew today's puzzle solution, as I had played over this game without guessing the moves. Your post gave me a very nice challenge! |
|
| Dec-07-16 | | JASAHA: Timman must have been short on time. I can't see him falling for this stunt if he'd had a decent amount of time before move 40. |
|
| Dec-07-16 | | BOSTER: Main idea is to put white rook behind black " d " pawn.
White king can take black rook , and give black the tempo to push pawn on d2.
But if you see this pos , you understand that black king can be moved to 4 rank by force, and after simple check white rook is behind the black pawn. |
|
| Dec-07-16 | | BxChess: Okay. I see now that you can't transpose the move order. 34 g4+ Ke5 leaves white with no good options --as earlier kibitzers said. |
|
| Dec-07-16 | | RandomVisitor: 18...0-0-0 = |

 | | Bubo bubo: After 35.Kxd5 d2 (otherwise 36.Rc3 and 37.Rd3), White can win a vital tempo with 36.g4+, and whether Black captures or not, his king has to enter the fourth rank, so the rook can access c4 with check and will reach d4 just in time to stop the pawn. Actually not that difficult, but it took several minutes and futile calculations of alternative lines (e.g. 35.b6 d2 37.b7 d1Q 38.b8Q Qd3+ 39.Kb4 Qb1+) before I finally realized that the Pd2 is not at all unstoppable. Again I'm a bit disappointed by myself... |
