 * Home * People * Leonid Liberman**

a Canadian chess programmer and author of LL Chess, famous for posting turbulent mate in N positions in CCC, forcing many engines to "explode" even in quiescence search. In his publications on computer chess from the mid 90s, hosted by //End of the World Production, LLC.//, he elaborates on x86 assembly, board representation, piece coding and move generation, mate solving, and point values.
