So I assume that Tiger with book will be more instructive for you to find which
opening positions to fix. I can continue using book then. Tiger had always less
time than movei (except for the first four moves). If I use no book then movei
will have more chances to win, but you want to win because of time advantage or
improve the engine and win by quality of play?
