I really believe it could work. Not Monte-Carlo chess, of course. But I was under the impression that using domain knowledge to prune or reduce late moves is a good idea. I am not following computer chess that much, but I believe some do it already. I think the algorithm in my paper would be a very good tool to design such pruning or reduction heuristics.

Abstract:

"....A 19×19 Monte-Carlo program improved with these patterns reached the level of the strongest classical programs."

You seem total ignorant that your paper reports nothing new wasn't it that you combined it with monte carlo method. Remove the word "monte carlo" out of your paper and you basically claim something that already gets used for 30 years in computer chess.

Apart from that i'll have to dissappoint you that if in diep i just see tactics deeper, that it doesn't play better at all. Experiments showed a score reduction over 1000 games against other programs at slow time controls (40 in 2 hours), an experiment that has eaten quite some system time you can say, a score reduction of 20-25% against commercial programs.

that is about 140-200 of reduction in elostrength when just seeing tactics deeper last few plies.

In Go that still works because programs are tactical that pathetic bad as of today that all their mistakes still can be seen as tactical mistakes.
