So What engine is _really _ the strongest? If you look for strength I suggest you look at the SSDF-list and then decide how much you believe in it. I hope you don't think that if one program is stronger than another, that it will always find better moves faster? The top programs are so close in playing strength that it just won't happen. > > 3.

A human can play a great move without being sure it is winning. He can play a move he thinks is winning but when looked upon closer it turns out to be bad. Of course there will always be moves played by humans after a short think, which computers can't find. A human can be lucky or use intuition. Or have superior knowledge. I don't own a lot of top programs but I guess all have their weaknesses. For analyzing I guess there is no "best" engine. If you look at how the programs play I am sure you will be irritated regularly because there is a lot of things they don't understand. Take Hiarcs, I could make a pretty long list of weaknesses. I am sure other people can make similar lists for other programs. But I would not call Hiarcs tactically weak, which you seem to think. I have the impression it usually is pretty fast to find moves like this, but some positions suit some programs better than others, thats life. I am certain that if you feed a lot of positions like your to the top programs there is no program that will find all best moves, even less so find them before all other programs. That would be asking for too much. Note that the position you asked about is highly tactical. What about positional ability? Endgame knowledge? Which program you would prefer for analysis probably depends on your personal preferences. Ask around (or try them all :) . Ralf
