I gave Junior5(16 bit pentium200MMX) the position and it wanted to play
25...Bxf4 before it found 25...Bh8 after a long time(more than 20 minutes).
After more than 5 hours I found that it wanted again to play 25...Bxf4
expecting 26.Rxf4 d4 27.Na4...(I do not remember what after it) with a small
advantage for white(I think 0.11 pawn but I am not sure).
