 | | David2009: Wednesday's puzzle S Yuldashev vs Aronian, 2004 White to play 31...? Medium-Easy It is mate in four: 31...Rxh4+ 32 Kg2 Qxg3+ 33 fxg3 Rxg3+ 34 Rf1 Rxg1#.
Time to check:
=====
Yes |

 | | patzer2: The combination begins at least one move prior to today's puzzle selection. After 29. f4? (instead White could try 29. Rbb1 Qf6 30. Bh2 Qxh4 31. Rxg6 Rxg6 32. f4 exf4 33. Qf3 Bxf2 34. Qxf4 Qxf4 35. Bxf4  with practical drawing chances), Aronian wins with 29...Rg4! White can avoid the immediate mate with 30.Rg2 exf4 31.Rxf5 Rxh4+ 32.Rh2 Rxh2+ 33.Kxh2 fxg3+ 34. Kh3 Qg4+ 35. Qxg4 hxg4 36. Kxg3 d6  , but is likely lost in this piece down ending. Earlier, White might have tried 23. Bd6+, when play might continue 23...Kg7 24. Rxg6+ Qxg6 25. Qe4 f5 26. Qf4 Kh7 27. Qg5 Qxg5 28. hxg5 Rxg5 29. f4 Rg4 30. Ra7 Bxf2 31. Rxd7+ Kg8 32. Rc7 Be3 33. Bxc5 Rh4+ 34. Kg2 Bxf4 with a complex but roughly even position. |

| | patzer2: <Was black's king walk to the kingside necessary?> In order to secure the King and clear the g-file for an attack on White's position, I think it was an essential part of Aronian's plan. The computer seem to like this idea, with Fritz evaluating 23...Kg7  as its best move. |
|
| Oct-14-09 | | stacase: 31...Rxh4+ is the only move to make. 32...Qxg3+ not so obvious )-: |
|
| Oct-14-09 | | TheTamale: Well, it's not every week that TheTamale gets a Wednesday puzzle right. But I concur with the others that this one was actually easier than yesterday's. |
|
| Oct-14-09 | | Elrathia Kingi: When first playing though this game, it looked like 23. Ra8+ followed by a rook exchange was the right move. All of black's pieces are focused on the g file and pointed at white's king. Yuldashev should have traded down to neutralize the attack and take advantage of the extra pawn. |
|
| Oct-14-09 | | Killingsworth: I think that Monday and Tuesday we were all looking a bit too deep. The simple initial positional and material advantage was all it took for the win. Today's puzzle was a neurological slackers dream.
Rh4 with everything forced afterwards. |

| Oct-14-09 | | goodevans: <A Karpov Fan: easier then yesterday imo> My theory - which is backed up by absolutely no research whatsoever - is that the two principal thought modes for tackling chess puzzles are pattern recognition and analysis, and that for experienced solvers the first of these is primary. Inexperienced solvers, almost by definition, will rely more heavily on the latter. Today's position involved a combination of familiar patterns so the prime candidate will have leapt out to experienced solvers immediately. It did, however, require a bit more analysis than for yesterday's so, bearing in mind that the early week puzzles are aimed primarily at less experienced solvers, probably justified being a Wednesday rather than a Tuesday puzzle. For what it's worth, I got both yesterday's and today's almost instantly but spent much more time on Monday's! |

 | | johnlspouge: Wednesday (Medium/Easy)
S Yuldashev vs Aronian, 2004 (31...?) Black to play and win.
Material: Down 2P. The White Kh8 has 2 legal moves, g2 and h2. The Black triple battery Rg8, Qg7, and Rg4 x-rays g2 and pins Bg3 to Rg1. The White Ph4 is therefore unprotected, suggesting 31…Rxh4. The flight square g2 makes the continuation problematic, suggesting 31…f3, which fails to 32.Qxf3. The Black Be5 attacks the White base Pf2, suggesting 31…Bxf2. The Black Kh7 is vulnerable to 31.Qe4 and (worse) 31.Rxh5+ Kg6 [Qh6 32.Rxh6+] 32.Qxg4,
which eliminates all but 31…Rxh4+, because a good candidate must be forcing or have defensive qualities. Candidates (31...): Rxh4+
31…Rxh4+ 32.Kg2 [Bh2 Rxg1#]
32…Qxg3+ 33.fxg3 [else, Qxg1#]
33…Rxg3+ 34.Kf1 Rxg1# |

 | | Dr. Funkenstein: Why doesn't white play Qxf3 all the back when Aronian trades off his light squared bishop. Doesn't black have as many weaknesses as white after the queen exchange on f3? |
|
| Oct-14-09 | | jsheedy: 31...Rxh4 jumped out at me. Pretty easy for a Wednesday. |
|
| Oct-14-09 | | lzromeu: I do it. But I Spent time with Fxg3. |
|
| Oct-14-09 | | costachess: 17. Qxf3 is better. The white must exchange the queens to less opportunity of black having mate. |
|
| Oct-14-09 | | TheBish: S Yuldashev vs Aronian, 2004 Black to play and win (31...?) "Medium/Easy"
Material: Black is two pawns down.
A quick glance shows that White is threatening 32. Rxh5+ Kg6 33. Qxg4+, so Black has no time for 31...fxg3? 32. Rxh5+ Kg6 33. Qxg4+ Kf6 34. Qxd4+ and White is clearly winning. So Black needs something more forceful, perhaps a check... 31...Rxh4+! 32. Kg2
Or 32. Bxh4 (Bh2) Qxg1#.
32...Qxg3+! 33. fxg3 Rxg3+ 34. Kf1 Rxg1#.
It seems like a composed exercise, because Black's troops are perfectly positioned for all the pseudo-sacrifices. |
|
| Oct-14-09 | | Dravus: For White, what about 30 Qe4ch, then the Queen takes Black's bishop? |
|
| Oct-14-09 | | Dravus: Oops, it's 31 Qe4ch I meant. |
|
| Oct-14-09 | | brainzugzwang: Apparently, I'm among those who found this easier then Monday's and Tuesday's puzzles. With the battery down the g-file and knowing ofrcing moves had to be made because of White's threats, 31...Rxh4+ just jumped out at me right away. HAve to admit, at first I was reluctant to sac on g3 because the pawn recapture might allow the White Q to stick her nose in, so I was toying with Rh2+, but that fails to Kf1. So in searching for a followup to Rxh4+, I saw that 32... Qxg3+ 33.fxg3+ Rxg3+ allowed our old friend from the Reinfeld books, the R+B mating pattern, to come into play. Surprisingly obvious for an out-of-practice patzer like me. |

 | | beenthere240: Not only is the white queen useless in preventing the attack, she also blocks the king's escape after 34. Rxg1 |
|
Oct-14-09
 | | chrisowen: I guessed it right, there's no pudding for white's rook on h5. Rxh4 Kg2 Qxg3+ where Levon's sicilian gives him the good ol' ecky thump! |
|
Oct-14-09
 | | Marmot PFL: I could see the storm coming on the g file. White should have traded rooks when he had the chance (23 Ra8+) |
|
Oct-14-09
 | | kevin86: Saw the first moved-missed the 2nd |
|
| Oct-14-09 | | randomsac: Got it. I immediately homed in on Rxh4+ since the bishop cannot accept it because it uncovers Qxg1#. |
