I had posted this puzzle awhile ago...I wonder if everyone forgot about it...Anyway, I am going to post a position, and when the right move has been stated, I post the next position, until the puzzle is solved. (No quick solutions for all you lazy people.)

i think i found it.

Bh3

i don't know, i give up

Lol, well, it isn't easy, that's for sure. But black can win with mate in 5. (mate in 6 from the first position.)

I don't even see a Black win in the position you posted, let alone a mate in 6.

You are supposed to analyze the position in depth in order to know how to play the mate. I admit, white does have an escape in the initial position, but not after

1. ... Bh3  2. bxc7?

Here is the puzzle in its entirety. If you have any dignity though, you'll avoid using help feature.

This is a very cool puzzle. Did it arise in an actual game (if so, do you mind sharing). The initial position looks like it came from a KID Mar Del Plata game.

not much hard

@ vaisakh1989s

From the initial position, it would be fairly difficult to rationalize a queen sacrifice. With so much going on, the challenge would be "Can I mate his king?" If you aren't confident, you would not look for the mate, and therefore prepare to bunker in for a long endgame instead. The real question is, did you use the help feature, or solve it on your own?

@NickYoung5

The original game was "GM Lubomir Ftacnik - GM Ognjen Cvitan". Took place in Germany, 1997.

Found it, thanks!

Though doesn't 2. gxh3 save the game for white ?

Figured it out but its not an easy find if you don't calculate. If you realize the king can't escape, the tactic shouldn't be too hard to find. I don't play the KID so I wouldn't know how to place my pieces; Black's kingside pieces are all perfectly positioned to wreck the White king.

Oh, I thought it was a (relatively) recent Nakamura game.

Very nice queen sac, impressive to be able to spot it from the original position (I didn't), thanks for posting.

Yep. I wish the daily puzzle would use these types of puzzles, and not the annoying ones which are so obvious I see the solution in 5 seconds or less.

Yes.  2 gxh3 leaves White with the advantage.  It isn't a mate in anything, unless White plays badly.

 OK guys, you gotta look into the position if you want to see. Black has the advantage after gxh3 (wins a rook and pawn for a bishop.)

Well of course white wins in your case! Black just sits there moving his queen 80% of the time, and his king makes a pointless move as well. Just waiting for your opponent to slaughter you while you don't remobilize fails completely! The moves Qc8 and Kh8 I find especially troubling. Those just aren't good. Qe6 appears far more useful. Now, I am going to say I think black has the advantage, being 3 points up. Replace all those pointless queen moves with something good (black moving his kingside pieces over to the queenside) and I think you'll find white, at best, will pull off a draw (though I doubt it). Besides, if you disagree, you could always take it up with Grand Master Larry Evans! (I got the puzzle/analysis from his book The 10 Most Common Chess Mistakes.) I think his word is pretty creditable.

"The only way to survive is to give up the exchange by 2.gxh3 Qxh3; 3.Rf2 gxf2; 4.Bxf2 and white must fight for a draw." (Evans 247)

Still, you could post the position in the game analysis section as well and see what the load of other members think.
