I'm sorry? Who in god's name folds a straight flush to a higher one? The only time I think that is remotely possible is with a KQJTs board and one guy has a 9 of that suit and the other guy has the A of that suit. the turn the guy with the 9 is check raised all in by the guy with an As ...... when the guy with an As thinks about it for 5 minutes and saying, "Are you bluffing?" then double checks his hand a gajillion times. And after the guy with the As reraises all in he pees his pants because he's never had a royal in his life, and his friend randomly put up a $10000 prize for whoever hits a royal flush at their home game. ..... And the guy is so anxious to flip over his cards that it looks like he may have a stroke if he doesn't in the next few seconds.... Yeah I'd consider folding then.
