(16.19). I think Eugene might have a minor glitch in the probe code, and he is looking at it, as we only need wtm for the kqqkqq type files as they are symmetric with white and black, and it is just a matter of inverting the board and probing to get the right score. He thought he was doing this, but I was only seeing hits on every other ply, which suggested that it might not be working right. in any case, download 16.19 source, add the -DEGTB6 compile option, and you are ready to go, although maybe not quite optimally just yet... and I would generally not run with just a couple of 6 man files in real games, as it will try to probe on _any_ 6 man ending and most will be rejected, wasting time. > >On September 23, 1999 at 09:48:53, Robert Hyatt wrote: > >>On September 23, 1999 at 09:26:13, Peter Marko wrote: >> >>>Hi, >>> >>>Guy Haworth has asked me to take the baton from him and organize making this >>>wonderful new tool available to the World Team in the Kasparov vs. The World >>>interactive game.
