Subject: Detailed Rebel 12 Bug

Author: Nolan Denson

Date: 20:31:05 10/08/03


Ok, here is a recent game on ICC where Rebel 12 crashed when getting a big lead.
Basically ... Rebel 12 Was white. Please note the info found in the debug file.

If you looked at the debug file you will notice after c8e6, the next info in the
debug file was quit.  Well what happened on ICC, Rebel 12 actually seen a mate.
Its value shot high, then i seen it made a mate announcement .. but what came
out on ICC was, a display window popped up with mate 0-1 and rebel stopped
playing.  That score should have been 1-0.


[D]2b2rk1/1p3p1p/r2p1p2/p3p3/1q2P3/1P2BP2/4Q1PP/1RR3K1 w - - 0 27

Please note from the debug file you never seen crafty move its Queen to E2.
Once the Queen was at E2 and its opponent move c8e6 ...qf2 followed by Qg3 !!!!
Some how the program freaked out .. My guess is .. I had the EOC feature on, and
it freaks .. I only see crazy things like this when using eoc.

(I am providing this info in hopes it can help figure out whats wrong)
