Subject: Rebel 10 plays the Kotov - Botvinnk Ending

Rebel 10 will play these moves at 40/2. Previous Rebels could not.

Machine is a K6-233 in Dos mode and 60 MB hash.
Combination is off and all else at default (the default mode for Rebel 10 when
playing games).

Initially it plays g5 (2:37) but without the correct followup in the eval,
namely d4. However it finds
d4 (4:47 - 15th ply) when that position is reached.

These are from the game Kotov Vs Botvinnik:

8/8/4b1p1/2Bp3p/5P1P/1pK1Pk2/8/8 b - - id end08 - Ecm98; bm g5;
8/8/4b3/2Bp2Pp/7P/1pK1Pk2/8/8 b - - id end09 - Ecm98; bm d4;

One puzzling thing is that I double checked these positions in Windows95 mode
with
28 MB hash. The d4 move was not found in the 15th or 16th ply. I thought it was
due to
Windows but it turns out that the 60 Mb vs 28 Mb of hash somehow makes a
difference.
Why is this ? Does hash size effect the eval even when the hash is not filled
up?
