I don't like the flop c/r. Even donk / call is better. He's got an A or J much too great a % of time to give you the correct equity.

I personally would check / call w/ 7 or 8 outs and a few implied odds. Imo, check / fold is not a huge mistake here.

You have 4 clean outs to the nuts (and actually you split sometimes so maybe 3.5), 2 probably good outs w/ the 2 Ts, and 3 Ks, but I'd only count the Ks as 1.5, for the times he's got a Q, so that gives you 7.5 outs getting 1:5.33. A little less then you need, but I think the Qs, Ts, and times you are ahead of 99, 88 and sometimes 77 give you enough implied odds to peel (although from the way you played it he does not have a smaller PP).

Also, what does c/r accomplish. You get 3-bet by better hands, and if he does happen to have a small pocket pair he will sometimes fold it, and you for sure don't want that. So, check call is better from this point of view too.
