If your guess is good, you can choose to either move immediately, or calculate further. Of course, both are helpful depending on the situation. Here's a quick example. Amateur was playing today against Pharaon (Zchess) on ICC. It had guessed the move, and was on ply 7 when the opponent moved. Time was available, and it kept searching, failing low on ply 8, and then making a better move. However, the opponent chose that moment to disconnect, and then immediately re-connected, resuming the game. Amateur then had to recalculate the move without the 5-10 second benefit of thinking on the opponent's time, and never reached deep enough to get the fail low. It made the bad move, and lost. Will
