More generally, you can raise alpha by the stand-pat score and then take a normal beta cutoff.Teemu Pudas wrote:Greater than or equal to beta.jfern2011 wrote:Upon entry into quiescence search, I've seen people compute a "stand-pat" score for the position, and if this value is greater than beta, perform a cutoff (returning beta).
Of course most nodes in a PVS search are searched with a null-window, so this works out to the same thing.
