Subject: SEE test results

Here are test results for 2 types of capture-search SEE
vs. none. The implementations are:

BASICSEE - cut out all capture moves in quiescence search
that lose material according to SEE

ADVANCEDSEE - search all moves to <2*iteration-depth,
search only non-losing captures to <3*iteration-depth
aearch only winning captures at 3*iteration-depth and
beyond.

Unlabeled - do not use see

I ran the 300 position test at 1 second per move,
5 seconds per move, and 300 seconds per move.

1 second per position - winner is NOSEE

I plan a run tonight for using SEE to order all captures & as above with
BASIC SEE; however preliminary tests at short time controls did more
poorly than the current implementation with a simpler move ordering.

SEE did not help me as much since my move ordering was already pretty good
since I rated all moves in my non-SEE implementation using a score derived
from MVV/LVA + History Historic + a Centrality term for captures.
