| Mar-07-11 | | David2009: Vasiukov vs Razuvaev, 1972 White 8? 8 Qc1 forks the Nh6 and the Bc8. If 8...Qa5+ 9 Bd2. Time to check:

7...Nh6? "A N on the rim is dim" but not usually this dim. <Once> Good posts - but the savvy Pirc/Modern Defence player refuses to 0-0. "Castling is like marriage - not to be embarked on irresponsibly" (Cecil John Seddon Purdy quoted by <whiteshark> Oct-06-08) |

| Mar-07-11 | | jackpawn: Normally I get Mondays literally in a second or two. Not today. Took me almost a minute to find Qc1. We all are programmed to look for the easy queen sac on Mondays. |
|
| Mar-07-11 | | The HeavenSmile: Not as clear cut as mondays usually are. Like <zb2cr> I also spotted Qe6 followed by d5 and this can be extended further as the a1 h8 diagonal has become open for blacks bishop, potentially threatening the white rook. I couldn't see a definitive line for black to take advantage of this though e.g. 8.Qc1 Qe6 9.d5 Qf5 10.Bxh6 Qe4+ 11.Be2 Qb4+ 12.Bd2 Qxb2 is promising, black can trade the rook for two minor pieces but unfortunately, white has mate in one. There could be a line here where black doesn't come out too badly |

| Mar-07-11 | | kevin86: I missed the Monday puzzle again! I'm getting as bad as LeBron James and the Miami Heat. 0 for last EIGHT The text is brilliant,and a very wide fork indeed. |

| Mar-07-11 | | SufferingBruin: <How many guys here think they have the board sight to see 8. Qc1 in a real game?> This, this, a thousand times this. Thank you, OBIT. |

| Mar-07-11 | | awfulhangover: It's only Monday, but it took me 1-2 minutes to find it. Didn't look for such a silent move. |
|
| Mar-07-11 | | BOSTER: It seems to me this is first Monday when <CG> being convinced that the queen sacr. is my steady habit, reducing my vigilance by provocative Monday puzzles with queen sacr. has caught me.
And I right away recalled that Karpov was caught in the same situation, when he did not see the double attack (fork). |

| Mar-07-11 | | TheBish: Vasiukov vs Razuvaev, 1972 White to play (8.?) "Very Easy"
This looks like an Alapin (c3) Sicilian, where Black normally plays 7...Nf6 or 7...Nc6. Instead, 7...Nh6?? (I'm assuming that was the last move) loses a piece. 8. Qc1! wins with the double attack on c8 and h6. Most people will see this, no doubt, but to get full credit I think you need to see not only 8...Qa5+ 9. Bd2, but also 8...Qe6 9. d5!; not too hard to find, but it would be easy to miss Black's defense here (even though White's response is easy). |
|
| Mar-07-11 | | stst: 8 Qc1 acts like a fork, targeting the c8 B and h6.
Bk could not escape losing a piece, since if 9... Bg4, 10. Bxh6 Bxh6 11. Qxh6 Bxf3 12. Pxf3 Qxd4 then W goes either Nd2 or exchange Q at d2.
If Bk chooses to give a check first at a5, then Nc3, or Bd2 or Qd2 at a later stage will stop that, rendering Bk no further threat.
If the Qs are off board, Bk is inferior with one heavy piece down.The trap in this puz is that it's still early in the game (only move 8) and it's not very likely that one side already has a "killer" move. Hence, in all probability, it should be a more subtle move to either gain advantage in position, or, more practically, materials, which is the case in point here. |

| Mar-07-11 | | Medieval Knight: Missed it. I can see it's going to be a long week. I was trying to trap the black queen. |
|
| Mar-07-11 | | Once: i think this is one of those occasions when the players might have found the solution more easily than we did. Normally we say that we kibitzers have an unfair advantage over the players because we know it is a puzzle, and a Monday puzzle at that. And all of that is true. But today the player of the white pieces would have been thinking about the key move - or at least the main idea - for several moves before the puzzle position. Here's the position after 3. c3
click for larger viewOne of White's plans from this position is Be3-Qd2-Bh6. Played at the right time, this sequence can neutralise the Bg7 and force its exchange. Then the black kingside has gaping holes at h6, f6 and g7. It's a standard plan and I would be surprised if white didn't know it. Black plays very aggressively to try to liquidate white's imposing centre. With d5 and c5 he gives white an isolated queen pawn. With Nh6 he plans Nf5 to embarass the Be3. And this is when white ought to be thinking "surely this can't be right?". Black is taking incredible liberties with his position - not castling, sticking his queen in the centre of the board, plonking a knight on h6 where it depends on the Bg7 for support, leaving the Bc8 undefended. And that is when white's spidey sense ought to be tingling or throbbing or whatever it is that spidey senses do. Black's moves look artificial and provocative. There must be something wrong with them. Given the white is probably already thinking of a Qd2-Be3 battery to nail down h6, it is not so hard for him to spot a slight variation with Qc1 which also hits the undefended Bc8. A tough monday puzzle for us which might not have been quite so tough OTB. |
|
| Mar-07-11 | | YouRang: Qc1 with double attack on the badly placed Nh6 and the unguarded Bb8. A nice lesson on what dubious opening moves (by black in this case) can accomplish. |
|
| Mar-07-11 | | YourNickname: I played this game with Rybka Tarrasch GUI, and i don't get why the GUI says that after 7... Nh6 8. Nc3 is a book move because Qc1 wins a Bishop. But this is not a reason to give up. Because after <8.Qc1 Bg4 9.Bxh6 Bxh6 10.Qxh6 Bxf3 11.gxf3 Nc6 12. Bg2 Nxd4 13. 0-0 Nxf3+ 14. Kh1 Qg5 15. Qxg5 Nxg5 16. Rd1 Ne6 17. Nc3 Rb8 18. Rac1 Kf8> Black is far from lose. |
|
| Mar-07-11 | | JG27Pyth: I had a moment of panic, thinking, but it's monday! I can't fail on MONDAY!? ... but after exhausting all possible queen sacs I did hit upon the double attack on c8 and h6. *Phew* |
|
| Mar-07-11 | | morfishine: <YourNickname>...<...Black is far from lose> Of course, while white wins a piece, 12...Nc6! is much better than 12...Qxf3 |

| Mar-07-11 | | M.Hassan: "Very Easy" White to play 8.?
8.Qc1
generates a double attack the outcome of which is winning a piece:
8............Nc6
9.Bxh6 Bxh6
10.Qxh8 |

| Mar-07-11 | | wals: Well I was having more trouble than scientists pondering om frictionless
neutron superfluid forming at the core of a neutron star.
The good old Queen sac didn't work
and even though I saw Qc1 did not
see the fork and gain of a piece.
Rybka 4 x 64: d 16 : 3 min :

 | | Phony Benoni: Beware, solvers; it looks like CG is throwing us a few curves these days! First, a couple of murky puzzles Thursday and Friday, then a couple of easier-than-usual ones on Saturday and Sunday, now topping it off with Non Queen Sacrifice Monday! Is nothing sacred? |
|
| Mar-07-11 | | David2009: I agree that Black could have tried 8...Bg4. One possible continuation:
8...Bg4 9.Bxh6 Bxh6 10.Qxh6 Bxf3 11.gxf3 Nc6 12.Qg7 0-0-0 13.Nd2! Nxd4
click for larger view (Black seems to be getting counter-play but it is all an illusion) 14.Rc1+ Kb8 15.Bc4 Nxf3+ 16.Nxf3 Qxf3 17.Qe5+ Ka8 18.Bd5 Qxd5 (or 18...Qf6 19 Qxf6 exf6 20 Bxf7 and White wins on material) 19.Rc8+ 1-0 <alexrawlings>: Thanks for the link! - nice fun game. <The HeavenSmile>: Your line for Black is tougher than the one I chose above (playing Black against Crafty End Game Trainer colours-reversed) but I think Black still loses with best White play.
For example (from your last diagram reached by 11...Qxf3 12.Rg1) 12...Nc6 13.Nd2 Qf6 14.Nb3 Rd8 15.Bb5 Rd5 16.Bxc6+ bxc6 and White is consolidating his extra maerial. |
