Originally posted by KorchVery nice, quite interesting too. I'd be hesitant to make a sacrifice as such, because there doesn't seem a clear way to follow - my main worry with that type of sacrifice is that you don't have a completely open e file to work with even after the sacrifice, which makes the attack hard to see. What factors led you to decide that the sacrifice was worthy?

In my game 11...b4 seemed to me risky move for black (in such positions flank operations with unfinished development cant be good idea) and I started to search how to punish the opponent for that and idea to sacrifice knight for leaving black king in center liked me very much - because I saw that after 14.Nxf8 black should take on f8 with rook, because if 14...Kxf8? then I would play 15.Qc4! winning. After 14...Rf8 I didnt see good plan for black how to consolidate their position and get their king our of center - they cant get their king to kingside (because Black cant avoid from whites bishop on a3), but queen side is too open for whites rooks.
When I planned 12.Rd1 and 13.Nxe6 I though only about 14.Nxf8, but also Rybka in position after black 13th mover says, that 14.Ng5 is better. But after 14.Ng5 Qb5 (only good move) 15.Qxb5 axb5 16.Nxf7 Rg8 17.Rd8+ Ke7 18.bxc3 Bb7 Rybka rates this position as equal and I would agree that dont need to be engine for making good defence for black.
As equal rybka rated position after 14.Nxf8 Rxf8 15.bxc3 after which black according to Rybka should play 15....Qa5 (instead of 15...Qb5) on which white have many possible answers, but as I said Rybka rates this position as equal which means that sacrifice was at least correct. But I`m not sure that analysing more long time engine won`t find whites position
as better or even winning. Anyway - maybe progs can defend such positions, but for humans it definetly is uneasy.

Interesting game. Just curious, how hesistant were you regarding the sacrifice? Many chess players feel uncomfortable giving up material unless they see a clear way to account for it. Sometimes this can be a limitation in their play.

Originally posted by KorchKorch, when I saw the sacrifice I looked at Qxd1 and white has a lot more active pieces after all the exchanges which I guess is why it is bad for black. I have always gone for the queen being better the few times I have come across this in my own games, simply because I don't know which is best. But could such a "counter-sacrifice" work if black was equally developed?

Giving up a queen for a rook and two pieces with equal development is almost always good.Game 2321906 even with perfect defense from move 17 on black should be loosing.However in this case white has better development too.

Sacrifices are very interesting. It is easy to understand that a sac gives a return of equal or more material value, even beyond my thinking horizon. Also when a sac gives a clear win. (But then it is not a real sac, is it?)
But a sac giving, not material value but, a strategic value, like destroyed king protection, a clear line, opportunity to double rook, make the others bishop imprisoned or another value not so easily calculable in terms of points. Those are sacs that is very interesting. I don't have any example of that at hand, I'm afraid.
There are a number of sacrifices with a certain theme. Like the Greek gift, poisoned pawn, desperados and such. Even gambits are sacs in a sense, giving an advantage in one way or another.
Sacs are very interesting. Pity that I don't find them when I need them...
I now study a book, called "Richtig Offern – Voraussetzungen, Ziel und Durchführung des Opfers im Schachspiel" by Rudolf Speielmann (1935). Gives a lot, worth reading.

This probably the game where I sacced the most for strategic gains.
Game 2402048
19...a5 try to tempt the defender of d4 away.
20...f5 offered pawn to try to get bishop on d4, and support passed pawn.
22...Bxd4 to remove King from blockading of passed pawn pair.
I don't think 27 and 28 count as a sac, but the knights were the only pieces which would be effective against the brutal passed pawns.
Game 2764496
I'm very happy with the offered bishop sac, 10...h5 which had a few points, 1) It'd open up the h file into the castled king position, 2) it would hopefully remove the knight at f3,which was defending h4, and blocking my queen from directly attacking the f2 pawn. 14...Rh1 was a pretty basic "sac" to allow my queen to get to the h4 square with gain of tempo.
