i agree with you chopper, some people will call a 2nd bet as well but I find a lot sit think and fold. If they call 2 streets while chasing I note it and take them to value town. It all really depends on board texture, if the board is extremely dry a lot of donks "put you on AK" and call you down. Its pretty player dependant but at my sites I don't find a lot of good floaters.
