You're playing NL holdem. Your opponent bets the pot on the flop and there's plenty of money left. Assume there is no suckout - whoever has the best hand now wins at SD. Raising is not an option at any point. Your choice is between calling on some or all streets or folding.

You judge your hand to be in the middle of your opponents possible holdings ie half his hands beat yours, half lose to yours. If he continues to bet the pot on the turn and river then you can call down. On average you split the money.

However, if he checks his bottom 25% hands on the turn and puts no further money in with them then you're only winning 1/3 of the time when he bets the turn. You can't call because you'll face another bet on the river and don't have odds. This also means you can't call on the flop because you now only win 1/4 hands( when he checks the turn) but are getting 2 to 1 odds. So you have to fold despite having 50% equity if all in.

A bit artificial, I know, but I think its interesting. You're opponent could only do this to you if he could pinpoint your hand. Information leakage at NL is bad.

Let me know if I've made a mistake somewhere.
