| Jan-28-16 | | thegoodanarchist: Sadly, 29...Kh7 does not help because of options such as 30.Nxf8+ Rxf8 31.Qg6+! and so sorry for Black. |

 | | Phony Benoni: Well, the queen's immune on e5. That' means she's immune on e6 as well! <29.Qe6+ Kh7 30.Nxf8+ Rxf8 31.Qg6+ Kg8 32.Rxf8+> with a backwards discovered attack. That means Black has to play 30...Kh8, but after 31.Ng6+ Kh7 32.Qxe8 Qxb1+ 33.Kg2, Black runs out of checks in a hurry since White has the Rf2 interposition. It's not as easy as all that. The first thing I looked at was 29.Rbf1, but 29...Qxf1+ turns that tables. |

 | | Penguincw: Thursday puzzle.
I think I came close. The solution I came up with (in about 10 seconds) was 29.Rxf8+ Rxf8 30.Qe6+ Kh7 31.Nxf8# 1-0, or so I thought it was mate, but black can flee to h8. Still, up a rook and knight for pawn seems winning to me. The line in the game, had it continued, is likely 29...Kh7 (29...Rxe6 30.Rxf8+ Kh7 31.Rh8# 1-0) 30.Rxf8 Rxf8 31.Nxf8+, and well, it's like the same thing, right? |
|
| Jan-28-16 | | dfcx: I went with 29.Rxf8+ Rxf8 30.Qe6+ Kh7 (Rf7 31.Qe8+ mates) 31.Nxf8+ Kh8 32.Re1 winning a rook. The text 29.Qe6+ is better.
29...Rxe6? 30.Rxf8+ Kh7 31.Rh8#
29...Kh7 30.Nxf8+ Rxf8 31.Qg6+ Kg8 32.Rxf8+ Kxf8 33.QxQd3 |
|
| Jan-28-16 | | devere: This problem is neither difficult nor artistic. 29.Qe6+ is flashy but 29.Rxf8+ Rxf8 30.Qe6+ looks slightly better to me. |
|
| Jan-28-16 | | LoveThatJoker: <29. Qe6+! Kh7>
(29...Rxe6 30. Rxf8+ mating; 29...Rf7 30. Qxe8+ mating) <30. Nxf8+ Kh8>
(30...Rxf8 31. Qg6+ and 32. Rxf8+ wins the whole enchilada) <31. Ng6+ Kh7 32. Qxe8 Qxb1+ 33. Kg2 Qc2+ 34. Rf2>  LTJ |
|
| Jan-28-16 | | jith1207: It is amazing how many times I think of a solution but refuse to even consider a different order of moves just because I assume that cannot work. This puzzle just reinforces that. |
|
| Jan-28-16 | | patzer2: Back on track this week in quickly visualizing today's Thursday solution 29. Qe6+! Kh7 30. Nxf8+ Rxf8 31. Qg6+ Kg8 32. Rxf8+ Kxf8 33. Qxd3 . Had this not been a blitz game, instead of 23...f5 = to  I'm sure Black would have seen the improvement 23...Rd8  (-0.96 @ 22 depth, Deep Fritz 15). Also with more time, I don't believe Black would have played the losing 24...Qxd3?? which drops a piece. Instead, he would have played a stronger alternative like 24...Qd8 or 24...Qg4 . |
|
| Jan-28-16 | | saturn2: I got most of it: 29 Qe6+ Kh7 30 Nxf8+ Now white is a rook and knight up and neither 30...Rxf8 31 Qg6 nor 30...Kh8 31 Ng6 Kh7 32 QxRe8 saves for black the game. |
|
| Jan-28-16 | | stacase: Only because it's a puzzle. I doubt I would have ever seen that one over the board. |
|
| Jan-28-16 | | agb2002: White has a knight for a pawn.
Black threatens 29... Qxb1+ and 29... Qxf5 (29... Rxe5 30.Rxf8+ Kh7 31.Rh8#). The first moves that come to mind are the direct 29.Rxf8+ and the flashy 29.Qe6+. In the case of 29.Rxf8+:
A) 29... Rxf8 30.Qe6+ Kh7 (30... Rf7 31.Qe8+ and mate in two) 31.Nxf8+ Kh8 32.Ng6+ Kh7 33.Re1 Qf3+ 34.Kg1 and there's no perpetual + - [R+N vs P]. B) 29... Kh7 30.Qf5 + - [R+N vs P] with the double threat 31.Qxd3 and the discovered check. -----
In the case of 29.Qe6+ Kh7 (29... Rxe6 30.Rxf8+ Kh7 31.Rh8#) 30.Nxf8+ Kh8 (30... Rxf8 31.Qg6+ Kg8 32.Rxf8+ Kxf8 33.Qxd3 wins) 31.Qxe8 Qxb1+ 32.Kg2 Qxf5 (or 32... Qxb2+, or 32... Qc2+, 33.Rf2 and mate soon) 33.Qh8#. -----
29.Qe6+ looks simpler. |
|
| Jan-28-16 | | morfishine: I've seen this. Nice finish, even if its blitz |
|
| Jan-28-16 | | ndg2: Devere is wrong, game continuation is more forcing than immediate Rxf8+ |
|
| Jan-28-16 | | whiteshark: I'm more of a Wednesday man |
|
| Jan-28-16 | | diagonalley: 29.Q-K6+ ... woo-hoo! ... don't often get thursdays! :-) |
|
| Jan-28-16 | | Cheapo by the Dozen: I whiffed, in that I didn't see Nxf8+ adding to White's material advantage. |
|
| Jan-28-16 | | CHESSTTCAMPS: White has the material advantage of a knight for a pawn, but also has all major pieces under attack. Regardless, white can force a quick win with 29.Qe6+ Kh7 (Rf7 30.Qxe8+ forces mate;Rxe6 30. Rxf8+ forces mate) 30.Nxf8+ Kh8 (Rxf8 31.Qg6+ K moves 32.Rxf8+ wins the Q) 31.Qxe8 Qxb1+ 32.Kg2 Qc2+ (Qxf5 33.Ng6+ Kh7 34.Qh8#) 33.Rf2 and the black queen has no more useful checks. |
|
| Jan-28-16 | | YetAnotherAmateur: Found it:
29. Qe6+
If black takes the sac, the ending is quick:
29. ... Rxe6 30. Rxf8+ Kh7 31. Rh8#
If black refuses, it leaves his position in shambles:
29. ... Kh7 30. Nxf8+ Kh8 31. Rf1 and there's basically nothing left for black to do except throw away pieces to get pointless checks. |
|
| Jan-28-16 | | kevin86: I went with R1E1 adding pressure; of course, the text is best...Too "simple" for Thursday. |

 | | Jimfromprovidence: I also went with 29.Rxf8+ Rxf8 30.Qe6+ Kh7 31 Nxf8+.

Its only defect is that it is a bit mundane. Giri played the strongest and most “puzzle-like” move in choosing 29. Qe6+. |

| Jan-28-16 | | CanITakeThatBack: I rarely get Thursday but I got it today! Didn't take too long either. WHAT'S HAPPENING TO ME! |

| | Peligroso Patzer: <kevin86: I went with R1E1 adding pressure; of course, the text is best...Too "simple" for Thursday.> Your proposed 29.Re1 is not good because of 29. … Qxf5 30.Ne7+ Rxe7 31.Qxe7 Qd5+ (or 31...Qf3+ 32.Kg1 Qxh5–+) 32.Kg1 Qxh5  . (Black has a clear initiative and very likely a winning attack. Since you gave your alternative move as [29.] R<1>e1 (when the simpler format of 29. Re1 is unambiguous in this position), it is possible you meant 29. R1<f>1, but this is also not good after 29. … Qxf1+ 30.Rxf1 Rxf1+ 31.Kg2 Rxe5 and Black emerges with a routinely winning exchange ahead endgame. The only alternative winning move to Giri’s 29. Qe6+ is 29. Rxf8+. |
