which engine(s) best play/understand the KID?
this is a favorite opening of mine but it seems that most engines i've used when analysing KID games just give white a large-to-massive plus out of the basic setup and for a good time afterwards (even in black victories). assuming they're wrong & theory is correct, what engines best evaluate and play the KID? i realize these two are not necessarily part & parcel.

Re: which engine(s) best play/understand the KID?
You will find this issue in the Reti Opening, English Opening and Dutch Stonewall... the engines don't understand these type of closed pawn formations... Perhaps, Rybka 4 will address this issue... if it ever gets release... the author did mention Rybka 4 would understand closed positions much better than Rybka 3...

Re: which engine(s) best play/understand the KID?
Have you tried the Monte Carlo analysis in Fritz11/12? It will work only with Rybka single core engine... don't make the mistake in using the Ryba mp version...
Monte Carlo analysis would perhaps give you a more "correct" evaluation instead of depending on the PV of the engine...

Why not play a KID theme tournament? Should be interesting.yanquis1972 wrote:this is a favorite opening of mine but it seems that most engines i've used when analysing KID games just give white a large-to-massive plus out of the basic setup and for a good time afterwards (even in black victories). assuming they're wrong & theory is correct, what engines best evaluate and play the KID? i realize these two are not necessarily part & parcel.

Re: which engine(s) best play/understand the KID?
The position is not really closed here yet. Rainbow Serpent gives +0.6 pawns for White, mainly for the space advantage I think. For Rainbow Serpent that is not a very big opening evaluation. But it probably does not understand much about fianchettoed Bishops or important diagonals. I don't know much about the King's Indian, do you have some example positions that you tried to analyze and where Rybka or other engines really make fools of themselves here?

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Re: which engine(s) best play/understand the KID?
Stockfish 1.6.3 JA gives a little less advantage, +0,5 for White in the same position. Jim Ablett's compile is about 10% faster than Rainbow Serpent in nodes per second on my machine, 32 bits Windows.

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Re: which engine(s) best play/understand the KID?
My engine gives it a +0.4 (it is interesting that the score has a tendency to go down in this position also in Stockfish). But that's quite natural - most engines like mto play with more room.
Code: Select all

Re: which engine(s) best play/understand the KID?
Rybka and Toga play the KID well, but you'll have to "help it along" in two occassions, to avoid locking up the queenside for white, and to suggest to Rybka to play on the Kingside for black instead of defending on the queenside as it will sometimes do in the closed positions (but that's not to say that defending on the queenside is not objectively the correct route). If you make a couple of moves on the Kingside, it will set it on a path where there's no turning back, and it will continue attacking. But I'd like to emphasize that Rybka and Toga 1.4.1 SE play KID well.
