Haven't you regular poker players ever played something that the computer says you shouldn't because you "had a hunch"? If player #4 had the kill button for that long, he may flop another winner. On the other hand, if he's wondering whether he should play for the raise, he should fold.

I saw a guy keep the kill button for 25 minutes one night. When he had the bid blind, no one raised so he played a 3-2 off suit. The flop was 3-3-2.
