Subject: Value for Quiescence Futility Margine

I am reviewing old data from my first chess program as I rewrite it for the
second program.

I am wondering what value (relative to a pawn value) people use for thier
quiescence 'delta' value to prune capures when generating captures for the
quiescence search.

Previously I tried both 4/5 of a pawn (80) and 1 1/2 of a pawn (150) and found
80 a better value.

I will obvoiusly test this when ready with various values, but I am curious what
others are doing.

BTW.
The new program is: IAGA Chess Engine (I.C.E.)
