| Mar-20-06 | | Richerby: The position after 32.d4 would make a good Monday puzzle. |
|
| Jul-15-08 | | dzechiel: Black to move (32...?). Material even. "Easy."
Another straight forward position. White's poory placed pieces are unable to come to the king's rescue. Black starts with
32...Ng4+ 33 hxg4
Forced.
33...Rf1
There are two mates threatened, 34...Rh1# and 34...Qh4#. 34 g3
stops both of those mates, but allows
34...Rh1+ 35 Kg2 Qf1#.
Time to check. |
|
| Jul-15-08 | | wouldpusher: 32. ... ♘g4+! leads to a mate in three: 33. hxg4 ♖f1 34. g3 ♖h1+ 35. ♔g2 ♕f1# and offering material doesn't help anyway. |
|
| Jul-15-08 | | mig55: Or 35.../ Qg1# |
|
| Jul-15-08 | | zenpharaohs: Well Ng4+ is simple enough. I kept looking to see if white has an answer, but there is none. |
|
| Jul-15-08 | | patzer2: For today's Tuesday puzzle, Petrosian springs a quick mating attack with 32...Ng4+! See <dezechiel>'s post for analysis. |
|
| Jul-15-08 | | apexin: well 32...Nxg4 took me about 1 second to find. good game by Petrosian. |
|
| Jul-15-08 | | DeltaHawk: I got it. |
|
| Jul-15-08 | | vescovifan: the other guy certainly made some dubious moves... starting with 1. b3?lol |
|
| Jul-15-08 | | eyalbd: 30..h6! is a brilliant move since it looks like an innocent waiting move that frees the h7 square for the King and thus provokes the "freeing sequence" 32.♘d1 ♕e1 33.d4 which is the position of the combination. If white doesn't fall into this trap and plays the best move 32.♖a4 then black uses the h7 square and jump 32..♘h7, 33..♘g5 and white can't defend is king side position. Note that after 32.♖a4 white can't play 32..♕e1 because of 33.♖xa7 ♘g4+ 34.hxg4 ♖f1 35. ♖a8+ and black is the one who is mated. |
|
| Jul-15-08 | | ToTheDeath: Ng4 was the obvious candidate move, but it took a few seconds to find the follow up crusher ...Rf1. Good puzzle. |
|
| Jul-15-08 | | zooter: 32...Ng4+ is pretty easy to see, but after 33.hxg4 Rf1 threatening mate that cannot be stopped is tougher, unless there is an easier way to mate After
33...Rf1 34.g3 Rh1+ 35.Kg2 Qg1# seems like the longest variation |
|
| Jul-15-08 | | jovack: saw the knight move, then worked out the move order for queen/rook not too bad.... <30seconds |
|
| Jul-15-08 | | AccDrag: vesco, maybe 1.b3 is not so bad
http://www.chessgames.com/perl/ches... Many more 1-0 than 0-1. :-) |
|
| Jul-15-08 | | therevolver17: 32...Ng4+ 33.hxg4 Rf1 0-1 |
|
| Jul-15-08 | | luzhin: The tour of White's Queen's Knight (a3-c4-e5-f3-e1-c2-a1-b3-c1) is sublime in its pointlessness. |
|
| Jul-15-08 | | whiteshark: <32...Ng4+ 33.hxg4 Rf1> and white can't prevent mate. Instead 33...Rf2 34.Qxe4 is only a draw due to 34...Rf1 Qe8+. |
|
| Jul-15-08 | | 234: Monday puzzle Jul-14-08 <22. ...?> Geller vs G Garcia, 1978 |
|
| Jul-15-08 | | TheaN: 2/2
Hm, an all-forced Tuesday is rare these days, but I don't mind... less variations... none at all, actually. 32....Ng4†!
Had to come out of nowhere for White. With some strange moves he probably was thinking "hey, I'm still alive". Yeah, not for long. 33.hxg4
Forced. Still, Petrosian should play the right followup move. On the other hand, the useless 33....Qh4† can repeat the position after 34.Kg1 (Kh1?? Rf1‡ 0-1) Qe1† 35.Kh2. 33....Rf1
But in the position it's not too hard to see Black should switch moves. It was one of the main phrases of my Dutch Stappenmehode Stap 6 tutor: "if it doesn't work, switch the moves"; usually he was right in my case. Black threatens Rh1‡, and only ONE move prevents this mate. This move strikes twice as it also avoids the now created Qh4‡: 34.g3
Nonetheless, it doesn't help.
34....Rh1†
g3 doesn't not stop the check, and now the White King is entangled by its own g3-pawn and the Black pieces (and the e3-pawn). 35.Kg2
35....Qg1‡
Is the purest mate (compared to Qf1‡). I think it's debatable what the better mate is but it doesn't really matter. Nice finish by Petrosian. 0-1 |

 | | OhioChessFan: Obvious first move. Took about 10 seconds to find Rf1. I was wanting to play Qh4 next. |

I have the sligthest feeling that you searched the opening in correlation with its practioner on purpose :P. Nonetheless though, the Nimzovich-Larsen is not immediately equalizing and certainly not winning for Black, but it might have a little less prolonged advantage than the Ruy or Sicilian; it's more of a tactical struggle with usually better chances for White. I think White was too optimistic playing such ideas against Petrosian, he probably tried to avoid most of his opening theory, alas, that didn't work. |

| Jul-15-08 | | johnlspouge: Tuesday (Easy): Black to play and win.
Material: Even. The White Kh2 is stalemated, so checks are important. Both the Black Qe8 and Nf6 can check. Only Rf8 requires activation, but Nf6 blocks its f-file access to the battlefield. Candidates (32…): Ng4+
32…Ng4+ 33.hxg4 Rf8 (threatening 34…Rh8#)
34.g3 Rh8+ 35.Kg2 Qg8# |
|
| Jul-15-08 | | Rainier Wolfcastle: just nice! |
|
| Jul-15-08 | | johnlspouge: The mate is very similar to a previous puzzle
V Iordachescu vs Karpov, 2007 I can be taught! |
|
| Jul-15-08 | | MiCrooks: I found Nh5 which leads to an easy win and stopped looking, overlooking Ng4+ forcing a quick mate. Key variation in Nh5 is Qe2 Qg3+ Kg1 Rf3! which I should have known was too hard for a Tuesday :) but I only give myself a few seconds to look at these each day as I usually do them at work. Feel a bit chagrinned at missing a Tuesday puzzle!! |
