Hi Bob, Can you show me how to use the annotate command so that I can have the top 5 best moves sent to a file? > >2.

Ok I was estimating that 1/6. What I would like to know is lets say the top 5 choices are A,B,C,D,E after ~90 seconds. What do you think the likelyhood of crafty finding a different best move after an additional 90 sec that is NOT one of the top 5 choices we found in the first 90 sec considering all 5 choices? Thanks
