As Don wrote, the main problem of null move is the depth reduction. It hides long-term threats that the evaluation function might not be able to evaluate. even with a very good evaluation function, i would think that another problem (this is likely just restating what you and others have

It looks like the script cycles through directories, kicking off bots via a script file. Making that script file do some other server seems trivial. The trick in my mind is figuring out how to get things to terminate properly. I forsee two issues: 1. Supporting # of games to play before

I'm just now reading the article. Monte Carlo techniques have recently had success in Go played on a restricted 9-by-9 board. My hunch, however, is that they won't play a significant role in creating a machine that can top the best human players in the 19-by-19 game. The author loses credibility
