It may be interesting if somebody with faster hardware can give this position more time. We see here some pattern of failing low Kf2 fails low at depth 15 to a score of 0.62 pawns against white. f5 fails low at depth 18 to a score of 0.72 pawns against white. Bb2 fails low at depth 19 to a score of 0.72 pawns against white. Deep Fritz always find alternatives and it may find Bb4 at depth 19 but at some point the alternatives may be finished. The hardware that I used P850(64 Mbytes) is not fast enough and I also did not install Fritz8 in that computer so it may be interesting what can faster hardware and better software see in 24 hours(the same time that I gave my Deep Fritz).
