I know my post-flop line is wrong, but what's right?

Without reads why are you checking behind on turn? [ QUOTE ]
this table was playing very fast with lots of big action on marginal hands

[/ QUOTE ] I think a minimum check-raise by an unknown means very little here, he may have a 4, a naked 5, an over pair smaller than your queens etc. etc. Checking behind on turn, to control pot size might seem like a good idea, but against an unknown I am probably making a 3/4 to full PSB. Free cards make me sick, especially when he turns over A4o on the river.
