Not seen that name in a while. Matt Ginsberg is a man of many accomplishments, but I had heard of him due to his contributions to computer contract bridge - his 90s-era world computer bridge champion program Gib (Ginsberg's Intelligent Bridgeplayer). In bridge, a game of imperfect information, it used the approach of dealing thousands of hands that opponents potentially could have, analysing them with perfect information, and taking the action that was statistically favoured. Interestingly, bridge programs seem to have somewhat stalled since. No doubt they've been improved but they can't beat world-class players even today. Though that might be lack of resources thrown at the problem.
