Yes, and how many games are played in that way? And how many engines
have a search able to handle that? But if you
know that Fritz and Shredder can handle this I am happy to have
learned something new.

Think how you play yourself: you play 40/120. You decide to allocate
close to 3min/move. After 2 min 59 s you realize that the move you
think looked very good will give away your queen for nothing. Wouldn't
you spend more time trying to find a better move and be very upset if
someone came and pushed the "Move now"-button?
