how much credit do you give villain here? i seem to run into this a lot. would it have been better to bet the river 1/2 pot or 3/4 pot, and fold to a raise? or was the check/fold better?

how often is this a flush bluff when it's obvious i could have TP and had been trying to drive away the odds. (i was also afraid of Q7+ outkicking me here)

no reads, 1st hand...
