Good day,
A1600+, 64 mb hash, 3+4 + some 5-man Nalimov TB,
ponder off, Aristarch uses own book while Crafty uses S7 book.
Aristarch's parameter change:
dynamic_king_safety = 4 (default = 0)
table_base_depth = 4 (default = 1)
match, Blitz:25' 0
123456789012
1 Aristarch 4.21 ½1½10½11011½ 8.0/12
2 Crafty 19.03 ½0½01½00100½ 4.0/12
One of the games that I happened to watch, game 8: the ending was drawish, until
Crafty choose another path it considered still safe, but it was not. Maybe this
is a good test position for bishop of opposite color ending.
How long will your favorite engine analyze white has the decisive advantage?
[D]8/8/1b4B1/pP4p1/P1K5/5k2/8/8 w - - 0 73
