Re: EPD Endgame Suite
I used Martin positions to test 5 piece tablebase benefit. It took about
60 hours (1600 games). I played 4 engines from 100 first position against Stockfish as white and black. As I assumed it's impossible to see any benefit even if 200 endings is probably meaning 500 or more normal games.
Houdini: NOTB 104 with TB 106
Rybka4: NOTB 104,5 with TB 105
Critter: NOTB 94 with TB 92,5
Rybka4.1: NOTB 98 with TB 101,5
But Rybka 4.1 got totally whole 10 less than Rybka 4
