Folding the flop for one bet is cool

[ErrantNight]

your opponent is not betting any two overcards here. get that out of your head. he's betting pairs, flush draws, or straight draws. overcards check to the raiser the vast majority of the time. should you account for the possibility as an outside chance? perhaps... but you shouldn't presume that it's anything more than unlikely.

and it matters HUGELY if you're just as likely to get better than worse odds. and one of the MOST important things about this hand is that the turn will frequently give you, if not the best hand, redraws to the best hand. which means your implied odds can be large, and the turn can be easy to play. further, your opponents may face severe reverse implied odds.

If it gets raised behind you, you're certainly not happy, but it doesn't happen that frequently, and when it does, you've got enough chances to improve that it's not a travesty.
