In regards to the a7o hand on k7543 where we lead turn and check fold river, how do you randomize the times you check river with a straight? You mentioned we have sets/2 pairs/ straights to call this bet on river, but how often are you calling a hand like a7 ( you mentioned you used a RNG to decide your action)

At around 22:53 You raise 97o from button and small blind calls. you flop top pair 7's and check back the flop. I am usually betting pot or over-betting here, trying to charge draws a bad price and force out over cards. Am i leaking with this line? I have seen other pros here making the same check. Can you explain your reason for this line? Was it player specific, where you knew he would peel your c-bet lightly? I would like to understand the factors that favor a check in this situation. Am I over-playing small top pairs here? Any advice would be appreciated. Thanks for the excellent video.

Hi, at 27:16, you assumed most of his bluffs should be A high, which means A7 should be a pretty easy fold. A counter argument would be he is more likely to have A6 when he checks back flop and calls turn, which makes A7 a better call. How does one balance these two factors and make a better calling decision?
Also shouldn't a 7 be a better call than a K, given he is more likely to check 76 than K6?
Final question, do you generally have a particular flop c-bet sizing for a particular board flop, or do you vary it according to your particular hand, based on the blocker effects. Thanks in advance :)
