>Try running your other programs without egtbs and let me know what they say.

I'm not sure how much egtbs would help, since it takes a while to get to 5
pieces in most lines.

Without egtbs my program (Altamax) gives
 1 -1.22 axb5 <eval>  44.0n /0s = #Infn/s
 2 -1.20 axb5 Be3 <eval>  120n /0s = #Infn/s
 3 -1.22 axb5 Be3 Kc6 <eval>  319n /0s = #Infn/s
 4 -1.31 axb5 Be3 Kc6 h4 <eval>  925n /47.0ms = 19.7kn/s
 5 -1.07 axb5 Bg7 Ke6 Kf3 Nc5 <eval>  2.40kn /62.0ms = 38.7kn/s
 6 -1.30 axb5 Be3 Na5 h4 Nc4 Kf3 <eval>  6.14kn /125ms = 49.1kn/s
 7 -1.38 axb5 Be3 Na5 h4 Nc4 Kf3 Kd6 <eval>  12.7kn /250ms = 51.0kn/s
 8 -1.56 axb5 Be3 Na5 h4 Nc4 Kf2 Nxe3 Kxe3 <cache>  30.4kn /609ms = 49.9kn/s
 9 -1.65 axb5 Be3 Na5 h4 Nc4 Kf3 Nxe3 Kxe3 <cache>  73.0kn /1.33s = 55.0kn/s
10 -1.82 axb5 Be3 Na5 h4 Nc4 Bf4 Nb6 h5 Nd5 Kf3 <eval>  246kn /4.26s = 57.7kn/s

proving that it is slow but not completely stupid. Crafty takes the bishop, at
least at the 5-minute blitz time control I used. After axb5, Altamax vs Crafty
and Crafty vs Altamax both led to drawn games.
