PostPost subject: check extension    Posted: Thu Aug 07, 2008 3:23 pm Reply to topic Reply with quote

when people talk of "check extensions", are they referring to:

(a) Quies() considers all checking moves and check evasion moves (in addition to captures, promotions). This implies that Quies must account for draw by repetition, since perpetual check could result, putting Quies in an infinite loop...

or do they mean

(b) the main search is expanded one full ply if side to move is in check

or do the mean

(c) both (a) and (b) above
