Subject: What kinds of (forward) prunning are known?

  Hi,
I would like to know what kinds of pruning are known (and/or used). To be
correct, I don't mean alfa-beta (which is safe), but I mean rather kinds of
forward-pruning(FP) (ie: not always safe...). I use this one: when it's last ply
to horizon AND  eval()>=beta AND not in check THEN return eval(). Are there
several (probably more brutal (?)) techniques in use (except null-move)?

  Thanks in advance

PS: But FP is very risky because (IMHO) better still to play average moves
    than excellent ones (but to make occasionally immediately loosing moves...)
