 | | scormus: Even if yesterday wasnt, this a definitely a material winning puzzle. W wants to grab that uncomfortable B on d4 but cant seem to get quite enough onto it. So a bit of cunning is needed 34 Ba3 looks like the move. 34 ... Rd7 35 Nc6. Possibly there ate other moves that would win. Not sure what B's best bet is, perhaps there isnt one? 35 .... 1-0 ? Better check, I expect I missed something |

 | | chrisowen: Tripilng row the rooks dfile doesnt work. Quite move 34.b4 bade farewell to raucous bishop in. It is cardinal sin Herman rummaging b5 black allow Na5 clubs d4. Exchange sac rooks cakewalk the rest. |

| Aug-18-10 | | kevin86: A real tough week-this one. |
|
| Aug-18-10 | | CapablancaFan122: Wow, I didn't get this one. I looked at Nc6 followed by Rxc6, but that doesn't go anywhere. <kevin86> It indeed is a really tough week. |
|
| Aug-18-10 | | KNIGHTSTALE22: It took me sometime to find b4 and Nb3, because like LIFE master AJ, I was looking for something spectacular. It gets me to wonder whether I carry this illness of thought into my OTB games? Am I looking at too many fancy ideas and hot shot killer moves, when in reality, simple plans and simple chess is the way forward 90% of the time!! |
|
| Aug-18-10 | | ClassZPlaya: <OBIT> Thanks! Yeah, mate-in-one is pretty stong. Embarrassing that I missed it. :-( |
|
| Aug-18-10 | | ZUGZWANG67: <LIFE Master AJ>: Simple puzzle. (34.b4 and 35.Nb3 " ") Not very satisfying though. Maybe I am too used to the spectacular, and the "HUM-DRUM" win of material here is not the kind of CG fare that I have gotten used to.
Am I being overly critical?
It's hard to answer your question. Nevertheless I think that we are being served very good puzzles this week. This forces us to analyse the position and not only looking for a Q-sac. Peace! |

| Aug-18-10 | | patzer2: For today's puzzle position, the little clearance 34. b4!, White is able to pile on and overload on the pinned piece with 35. Nb3  to win decisive material.Earlier, Black missed his chance of winning twice with either 21...b5!  or 22...b5! . The losing move was 22...f6?! Instead, 22...b5! 23. Na5 f5! is winning. |
|
| Aug-18-10 | | YouRang: Got it after a minute or so. It was pretty clear that the focal point is the pinned (but adequately guarded) black bishop on d4. Naturally, I really wanted to attack that bishop again. It took a while for it to dawn on me that black didn't have any quick way to help his bishop get out of trouble. That bishop isn't going anywhere, so I have time to vacate b3 with 34.b4! so that my knight can attack the bishop from there next move. There doesn't seem to be any way for black to avoid losing the exchange. Nothing brilliant, but good basic chess. |
|
| Aug-18-10 | | lost in space: LHM, this took me ages (most probably due to my negative IQ). I was looking to more or less every knight-move and recognized that there is no way to squeeze a win out of the position...Then I recognized that Nb3 wins if there would not be an own pawn on b3. And then everything was crystal clear. 34. b4! Kg7 (example) 35. Nb3 Black is completely helpless.He can not avoid that White will win Bd4 Nice and harder than medium |

Very concise and instructive explanations. Thank you |

| Aug-18-10 | | jimmyjimmy: I had to travel for my job last night so I didn't get to see the answers for yesterday's quiz. I bombed out today. I had to travel a lot and I couldn't concentrate. How do I see the kibitz comments from yesterday? I want you to know my hometown of Saint Louis,Missouri,USA has been chosen for the U.S. Chess Hall of Fame. We are very proud. I will play any of you for my dues at that club. If I lose I will give you as many St. Louis style pork steaks as you can eat. Any takers? |

| Aug-18-10 | | TheBish: R Grau vs Pilnik, 1938 White to play (34.?) "Medium/Easy"
White has Black tied up in knots, with a nasty pin on the Bd4 (if Black had the move, then ...Bxb2 would lose the exchange to Rxd5). The bishop on d4 is attacked three times, but defended thrice; how can we attack it once more? The knight on a5 is the only piece not really working, so let's get it activated. Once you realize the best square for it is b3 (now occupied by a pawn), the rest falls into place. 34. b4!
Now Black is helpless to stop 35. Nb3, and will be forced to play 35...Bxb2 36. Rxd5, losing the exchange and most likely the game. |

And after 35.Bxb4(forced) 35 ... Ra6 and I can't see any good continuation for white > 36. Nc4 the d4 Bishop is still pinned, we're basically back to the puzzle position with one less attacker (the DSB), one less defender (the a6 Rook) but Black's b Pawn is gone. |

| Aug-18-10 | | turbo231: chessgames must have a new guy rating these puzzles he needs practice |

Because Black would have played

| Aug-19-10 | | EXIDE: I missed this one. Did not see the pawn move freeing up the space for knight move. Well I missed yesterday,s puzzle too. First time I have missed one and two star puzzles. Are they getting increasingly more difficult than the usual ones ? |
|
| Aug-19-10 | | turbo231: I've been doing these puzzles over 2 years now and either I'm getting worse or chessgames has a new person rating these puzzles. |
