The computer may ponder about all the possible moves but use different time for different moves(I remember that I read that this idea is used by aristarch). If based on the scores it can see that there is a forced move it can give it almost all of the time but if it see 5 moves with almost the same score it can continue to analyze them and use almost 1/5 of the time for everyone of them. If the opponent use 30 minutes for his move when the average time is 3 minute per move and the computer used 5 minutes to ponder about the move that was played then the computer may reply in 0 seconds.
