Ooh a hand to talk about, nice. It's been a while.

Sample size is very small, tight over 40 hands can simply mean card dead.

Pre flop we can call or 3bet this spot. Folding is absurd though, our hand is too good to throw away to a standard raise even if we think villain is super tight.

Flop is a very easy c/c, we have middle pair and two backdoor draws.

Turn is as blank as it gets, we're either still ahead or still behind. It's not a great turn since hitting our second pair is now insufficient to beat a queen, but I still feel like we're ahead often enough to profitable c/c turn.

River is a tough spot. If he has a queen he's likely to check this river back to realise his showdown value. No reason to turn a Q into a bluff here. He either improved and we're behind, or he's triple barreling air. That seems unlikely given your read he's tight. I know I said 40 hands is a small sample, and it is, but it's enough to see him do something stupid if he's that way inclined.

I think river is a disciplined fold but it's close.
