Effectively it gives you a speedup of about 50% (assuming you correctly predict your opponent's reply about that often). I suspect this obvious guess would be about right for computer vs computer play. Against a human opponent, especially an opponent who hasn't played against computers much, and especially at faster time controls, i suspect the rating gain can be a lot more than that. There must be some psychological value in making instant (but good) replies in positions where your opponent expects you to have a long think. Bob Hyatt has said TOOT made a big difference to Crafty's rating on the chess servers. I can't remember if he gave an exact number, but i got the impression it was well over 100 points.
