|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|| ||Penguincw: < YouRang: Qc1 with double attack on the badly placed Nh6 and the unguarded Bb8. > |
I think you mean <Bc8> not <Bb8>.
|Mar-07-11|| ||M.Hassan: "Very Easy" White to play 8.?
generates a double attack the outcome of which is winning a piece:
|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.

|Mar-07-11|| ||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

(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.
|Mar-07-11|| ||timothee3331: How not to think of Christiansen Karpov ?!|
|Mar-07-11|| ||pericles of athens: attack unprotected pieces!|
|Mar-07-11|| ||1.e4effort: i looked at a few things before settling on 8. Qc1, and then i peeked at the solution as i couldn't believe Qc1 was the absolute best as black has too many answers for the threat. Can't believe black threw in the towel - Vasiukov must have had horrible breath or something....|
|Mar-07-11|| ||BOSTER: I guess if I saw the position like on diagram with white to move

I'd play Qc1 to win the piece.
It means that all other pieces on the board distract the attention from queen's move.
The real problem is how to keep an eye on the main actors of the action. The question is : how to find out who are they?

Scan the board for pieces protected as many times as they are attacked.
|Mar-07-11|| ||WhiteRook48: it was so easy that i <didn't> get it arrgh|
|Mar-07-11|| ||PeterB: Isn't Black a GM?? If so, there's hope for all of us...|
|Mar-07-11|| ||Sharpen Your Tactics: lazy day. i didn't spend a lot of time on it and didn't solve it. I have seen it this month in my tactic book.|
|Mar-07-11|| ||sevenseaman: <johnlspouge> <Scan the board for pieces protected as many times as they are attacked.>|
The aphorism might be hundreds of years old but remains the most elementary trick at the game. We sometimes do overlook it; so bears repetition.
|Mar-07-11|| ||BOSTER: <johnispouge> I don't think this is a correct answer, but thanks for your advice.|
|Mar-07-11|| ||cjgone: Wow, took me a while for a monday. :(|
|Mar-07-11|| ||Patriot: <BOSTER>
<johnlspouge> said it right. The knight is attacked once and defended once. The c8-bishop is attacked zero times and defended zero times. Now put the queen where it attacks both and you have a fork. The g7-bishop also meets the criteria but you need to attack two pieces safely to win one.
With more pieces on the board (as in the game), there could be more possibilities which is why it's a good idea to first look at forcing moves such as checks...then captures...then threats. After I got past the checks and some potential threats it took me an instant to see 8.Qc1 and a little longer to make sure it isn't easily refuted.
I think the trick is to scan the position and mentally highlight loose pieces, stalemated kings, open kings, pieces on the same line, etc. to make these tactics more apparent.
|Mar-07-11|| ||alachabre: Well, I guess this one kicked my butt, because I would play Nc3 and hope to follow with a move like Bc4.|
|Mar-07-11|| ||Gypsy: It took me embarrassingly long.|
|Mar-07-11|| ||gawain: So simple. And I did not get it. I was seeking bigger fish to fry. Did not look for merely winning a piece.|
|Dec-26-11|| ||whiteshark: a golden opportunity ...|
