Well, it's supposed to be the best move. I don't know if it is supposed to win, because winning is very, very doubtful. However, from the root of the position, Pepito is the only program I know that can find an evaluation of 0.00 in a reasonable amount of time. Most programs will score the position from slightly negative to highly negative. Every program chooses the right move. But the hard part is finding a suitable score. Can other programs find the draw in a reasonable amount of time? I have not seen any others yet. >Thinking.... > > +---+---+---+---+---+---+---+---+ WAC.258 - Bxg6, Key: >8 | *R| | | | *B| *R| *K| | > +---+---+---+---+---+---+---+---+ 00:00:00 00:00:00 >7 | | *p| | | | | | *p| > +---+---+---+---+---+---+---+---+ >6 | | | *p| | | p | *N| | Time > +---+---+---+---+---+---+---+---+ Hash 2 Mb >5 | | | p | *p| | | | | Engine Rebel Century 2.0 > +---+---+---+---+---+---+---+---+ Personality "Q5T" >4 | | | | p | *p| | | Q | > +---+---+---+---+---+---+---+---+ >3 | | | | | p | | | | > +---+---+---+---+---+---+---+---+ >2 | | | | | | | p | p | > +---+---+---+---+---+---+---+---+ >1 | | | | | | R | | K | > +---+---+---+---+---+---+---+---+ 1..
