Ouch! that check-raise hurt.

[johnzzz]

I play on very loose tables, often with 7 or 8 fish (default PT classification).

I frequently get stung by check-raises. I'm playing pretty straightforwardly. Say I've got AA, then I'll raise preflop. I'll bet the flop and be called. I'll bet the turn and bang - get check-raise by someone with 2 pair or maybe a set. On the river the check-raise is usually a straight or flush.

Should I fold or call to the river?
