so obviously he went for a CR on the turn because he felt you were strong enough, and he also knew he didnt have the nut flush. the K-10 call preflop is pretty loose though.

I think he got you to call and that was great but he also didnt get max value for his hand.. so you can look at it two ways.. you playing as cautiously due to the information you have on him saved you some $$.

do you think you could have gotten him off the hand on the flop? what did you think he could possibly hold with a call of that bet on the flop?

by you checking on that turn you obviously were a little scared off by the 3rd club and then you called on the river after you missed a betting round. so with that in mind you should give yourself a pat on the back for a good read.. BUT you denied your first instinct and called on the river anyways.. i think you played it well if you were pretty sure he had the flush.. but if he even holds AQ you miss a lot of betting there.
