Mar-29-06		Rookinstein: <Tariqov>♖xg6 is the worst move u can play in that position. After ♘g6+ black played the only good moves available. And whats the huge difference between a 'mistake' and a 'blunder'??

Mar-29-06		Sleepyeyeguy: Was a no problem... piece of cake... piece of crumb cake.

Mar-29-06		Richerby: Bah. Did really badly with that one and missed all kinds of things. Unable to see anything else through to its conclusion, I put myself out of my misery with 27.♕xc5?? ♕xe1+ 28.♗d1 ♕xd1#. :-)

Mar-29-06		Richerby: <Rookinstein> I'd say that a blunder is a mistake that is bad enough to lose a piece or to lose the game instantly or, at least, very quickly. Other people will, of course, have different opinions and that's fine.

Mar-29-06		unsound: The mistake/blunder distinction is to do with the degree of obviousness. (A blunder need not lose--it could draw, or just reduce an advantage, say.) Of course what's obvious to a GM is not necessarily obvious to me, so what is a blunder for them would ususally just be a common-or-garden mistake for me.

Mar-29-06		The17thPawn: <Ashram64> and <Hudson Hawk> - I agree that 26...Bxe8 is much better but I believe White still picks up the c5 pawn with out to much fear of complications. Granted this wouldn't mean to much if Teschner were playing me, but Boleslavsky was known to make mince meat of world champs in his day. An extra pawn in his hands would probably have been decisive.

Mar-29-06		BLOODBROTHER: the game was good with white delivering constant and decisive blows with the queen.

Mar-29-06		YouRang: Jeez, I'm a moron today. I looked at 27. Ng6+ fxg6 for the longest time, but never bothered with the simple followup move 28. Qf4+! For some reason, I was transfixed on doing something with Bxg6. Good puzzle. I should have gotten it. :-(

Mar-29-06		YouRang: <Mistake vs. Blunder> Really, I think we're coming up with some ad-hoc distinctions here, IMO. Although "blunder" has become a standard chess term for a bad move, "mistake" is not a standard chess term, so if anything, it retains a more general meaning. All blunders are mistakes, but not all mistakes are blunders. For example, you might use "mistake" to describe a chess error other than a bad move, like clock mismanagement, underestimating your opponent, or touching the wrong piece.

Mar-29-06		kevin86: I answered this one correct. I think I picked up this weeks theme:combinations that yield simplification and positional gain instead of material gain. White ended here with a queen for rook and knight. Black's pieces were displaced and his king exposed- So a win was in the offing.

Mar-29-06		jenspetersson: Hmmpf, did I or did I not solve the problem? I found 27.Ng6+ and in all other variations I seem to have seen everything that needed to be seen. But in the main line I completely missed Teschners 28.-Rf6. Apparently it worked out anyway, but considering my luck - it wouldn't have done so in real life...

Mar-29-06		Castle In The Sky: I found the ♘g6+ and worked out all the variations,with fxg6 and the queen for the knight and rook being best. I didn't assess the positional advantage. I always enjoy this type of imbalance as the queen is many times overrated in power.

Mar-29-06		gotgat54: Here's a lovely variation: 27.Ng6+ fxg6 28 Qf4+ and now ...Qf7 (instead of ...Rf6) 29 Qxd6+ Kg8 30 Bxg6 Qf6 (OR 30 ... Qf8 31 Bh7+ Kf7 32 Qf4# ) 31 Qb8+ Qf8 32 Bh7+ Kf7 33 Qf4++

Mar-29-06		alefromitaly: Got it (even if in a line I initially went through the "hallucination" 27. ...Kg8 28. Qxe8+ Bxe8 29. Rxe8+ "Kf7" O_O).

Mar-29-06		uergash: I got it pretty easily but didn't know if Iwas right.

Mar-29-06		itz2000: 27 Ng7+, Rxg7(??) 28 Qxc5+(!), ? 29 Rxe8+(!!)

Mar-29-06		goldenbear: I don't know why(I'm more of a tactical player) but my first instinct was that this was some kind of "liquidation" puzzle so I analyzed a4, f3, and Be4 for a long time and found no advantage. It took ten minutes or so before I gave consideration to Ng6, although in the back of my mind I knew I'd check it out sometime.

Mar-29-06		belka: Personally, I found the key to this combination to be seeing the double attack with Qf4+. I'm always looking at checks (or at least trying to), so I will consider Ng6+. Since this is a piece sacrifice, I look at the acceptance first. Accepting deflects the f pawn and sets up the double attack (with check). Without the double attack, Qf7 saves -- you cannot sacrifice a piece just to give check, and a discovery on the queen is useless when the queen can block the check! And Rf6 (blocking and reversing the attack) loses because Rxe8 is check. These are the ideas -- 1. destroy the pawn cover, setting up 2. double attack. The rest are tactical details (Can the sac be declined? No, the king cannot move and Rxg6 is bad), which do need to work out, but they aren't the ideas of the combination.

Mar-29-06		PaulLovric: 35 seconds today

Mar-29-06		hayton3: First move I looked at - satisfied that all the variations were winning within 10-15 seconds.

Mar-29-06		McCool: Seemed pretty easy for a Wednesday puzzle.

Mar-29-06		yataturk: I'm not sure if white could've won here if it wasn't for the better pawn structure in the endgame.. I mean Q vs R+B doesn't seem like a killing advantage to me. What does endgame theory say?

Mar-29-06		hayton3: <yataturk> The Q usually wins - the side with R+B usually needs an extra pawn to have a chance of a draw. These are generalisations however as each position (placement of kings and pawns etc) offers it's own version of the truth in these matters.

Mar-30-06		Calculoso: <Rookinstein> A bit late with this but thanks. Completely slipped my mind.
