I am implementing multi as per schaeffer, see : http://www.google.com.au/search?hl=en&lr=lang_en&ie=UTF-8&oe=UTF-8&q=+site:www.cs.ualberta.ca+brute+force+selective+extensions+search http://www.cs.ualberta.ca/~yngvi/Papers/tcs2001.pdf The idea is, when you expect a cut-node (to fail-high?) (ie. in PVS alpha!=beta-1), search the first 12 nodes at r-2, if you get 3 fail-high, then fail high straight away, as probably one of them would have failed high at the real depth. Has anyone tried this? use it currently? In my implementation, I try multicut before doMove when alpha!=beta-1 and not root etc, if it suceeds I fail-high without doing doMove and searching at the current depth. Scott
