I have Komodo 6 and Stockfisk 6 (64-bit). I am now analysing the Caro-Kann Advance for Black with 3...Lf5 as home analyses. I tried both left on overnight on a critical position past move 20 and it made my laptop slower, although my laptop is new and fast (HP brand). Is Komodo should be the main engine nowadays then? When I quit one engine from the two it makes my computer faster again.

Even more confusing to me is that when I have both on I get things like this:

Komodo +0,32 Stockfisk +0,07

Sometimes also it goes one negative one positive:

Komodo +0,23 Stockfisk -0,02

So is one seeing something than the other?


I always use 1 engine per computer. Today I am using 2 engines for analyzing positions so I have 2 computers. This avoids the loss of time for swapping between both engines. An extra benefit is that I have also an extra screen on which I can permanently monitor both engines in parallel. That is still one less than e.g. Shipov when doing his online commentary see http://www.chessintranslation.com/2012/05/two-cats-and-three-computers-sergey-sh...

If you use the last versions of Komodo and Stockfish then I don't think there is any substantial difference in strength overall. That was also proven in the previous TCEC final. However each engine will have specific positions which are played a bit better than the other. So it makes sense to do the analysis with both.

Each engine has its own evaluationmethod. A small difference of evaluation between engines doesn't necessarily mean that some engine sees anything extra just that it evaluates the position a bit different. It is up to the operator to detect if the difference in evaluation is a matter of pure evaluation or more important moves. Sometimes it is sufficient to look at the mainlines but often more analysis is needed to understand the difference in evaluation.

Very interesting - is there a free version of this engine available to test?


Unfortunately no, there is not!
But, Komodo 6 is free already: http://komodochess.com/pub/Komodo-6.zip

I suppose Stockfish 6 remain for while the best choice. For accuracy, you can use 2 engine to compare. And your method, to advance one more or two moves ahead look good but take times and patience.

Btw, after 32 or max 40 is very rare to see same change in first choice of program. For open positions is clear, Stockfish is good analyzer, but for closed position Komodo is the best? Maybe is better to use 3 core...one for K, one for S, one for H...What your opinion,Mr. Vass?


TalJechin said it already:

One should use at least one engine from every one of the major 'families' as they all have different kinds of positions where one or two of them 'understand' the positions better than the rest.


And no, I never noticed Komodo to be especially good at analysis of closed position. It has other qualities though.

The question remain without answer. What engine is better in closed position?

I know your point. Still, if you buy a new processor 5960X I think, for your correspondence chess i can loose against me, if I use for exemple only i5 quad core, no matter is I will stay more time than you to analyze. Is not only speed, is also RAM, FSB..etc...

I am not sure about this. If I use octocore FX 8350 1 h sure is better than single core 8h.

I think for closed position Komodo can be a solution. For sharp could be Stockfish.
