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?

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.

Configuring the number of cores, hash size, endgame tablebases support and...pondering on/off and setting the proper use of opening books (if you do match tests between engines) is enough for a start.
For infinite analysis you have to configure maximum hash (irrespective of the engine you use). It means that if your PC has 2048 MB RAM, then your maximum hash size is 1024 MB. For matches between engines it depends on what time control they play. If it's the classical 5' blitz control - 128MB for each engine is enough (reading a big-sized hash file while playing blitz is counter-productive). 256MB hash for each engine is good for matches on 60'+15" time control for example...and so on..
"Large pages" can improve the speed of analysis with 10 to 15 per cents, but not for long (and not every engine can handle them right, too). And besides, you have to be experienced in order to set properly the "large pages" parameters on your PC (if it supports them, of course).
Usually, engines are not good with openings or opening-related positions. That's why their developpers recommend using human-made small opening books (up to 8-15 moves only). Do not rely on proper evaluation of the openings by engines up to the 15th move!
If you let them play in matches on their own, they'll probably start with 1.d4 d5 2. Bf4 Nf6 3.Nc3 Nc6, or similar, all the time.  Grin
...And yes, analysing on one core for two hours is better than analysing on two cores for one hour only.

My humble opinion: very good for infinite analysis and not so good for the Aquarium's IDeA way of analysis.
Still, my preferred chess engine is Houdini 4.  Wink

The new Stockfish 6 is available for download at https://stockfishchess.org/ and at https://stockfishchess.org/download/

It may be a good try for analyzing with it!  Wink

A few years ago, I found I got a lot of value out of Junior 10. Typically, it provided inferior analysis to Rybka, Deep Shredder, and Deep Hiarcs, but it also offered the most radically different options. Pairing that more aggressive style with careful analysis of the ensuing positions yielded me a number of points in correspondence chess.

Vass, Your 2.Bf4 reminds me of a new book that is coming out in a few months.
For Black, after 1.d4 d5 2.c4 (or 2.Nf3) it recommends 2...Bf5.
