OK so here’s a middlegame position - nothing special. It’s actually AnMon v Ikarus the games move was Rd2 but there doesn’t seem to be too many tactics flying about. [d]r1br2k1/1pq2pbp/2p3p1/p1n5/2NN4/4P1P1/PPR1BPP1/3Q1RK1 w - - 0 21 So my program (it has no name) takes 70 seconds and uses 17,059,562 nodes to complete the _eighth_ ply. There are also only 3.3% of nodes where there are a hash hit – a bit low maybe? Other programs: Faile 56 secs and ~4,600 kn Crafty 17.11 9 secs and ~1,500 kn Ikarus 22 secs and ~2,900 kn Goliath Light 8 secs and 1,800 kn HIARCS 7.32 36 secs and 1,692 kn Nimzo 7.32 6 secs and ~1,700 kn ExChess 3.11 9 secs and ~1,200 kn Clearly there is something wrong with my program or is this what one would expect from a young vanilla alpha / beta?
