Jonathan Schaeffer is a researcher and professor at the University of Alberta. He led the team that wrote Chinook, the world's strongest checkers player, after some relatively good results in writing computer chess programs. He is currently involved in the U of A GAMES group developing computer poker systems. The most famous of these is the Poki poker player which uses Monte Carlo simulation to both simulate and model human opponents. His group has also developed a computer player called PsOpt (for Pseudo-Optimal) which uses a mixed-strategy Nash equilibrium solution to a reduced form of Texas hold'em poker.
