That's true, I don't think it is a big problem though. If a TB mate in 51 moves is the best you have then the position is probably very drawish already. Without the TBs it is nearly impossible to find the best 51 moves, at least with TBs you have a practical chance if your opponent doesn't defend optimally. -S. >Uri
