Predicting the opponent moves is not very difficult. It happens often. There were cases when computer program predicted 10 of my moves in a row. I agree that if the human opponent is using a long time for one move(for example more than 10 minutes at tournament time control) it may be better to stop analyzing the reply for the expected move and start analyzing the second best move and after it the reply for the second best move but I do not think that this idea is very important. Another possible idea is if you discover by analyzing the predicted move that the predicted move may be a mistake(an extreme example is if the evaluation is mate foryourself after the predicted move) there is no point in continuing to analyze the predicted move and it is better to start to analyze a different move. There may be other cases when it is better not to analyze the predicted move but I think that in most of the cases analyzing the predicted move is the best way to use the time. Uri
