Personally I prefer to use the book the programs are supplied with. But using a book like remis.ctg isn't much different I think to using say the Nunn positions. Sometimes they will not play or have a position that suits the engine. However if enough games are played the engines strength will come out. I expect as more games are played Ruffian will catch up. My guess if 24 games are played the margin will be no more than what it currently is. Sarah. >Uri
