OR is a reg, he seems pretty good for the limit. He is running 23/18, 63% F3bet on 1.2K hands.
BB is a huge fish, pretty aggro, running 70/23 on 129 hands

Preflop is a bit lose but OR had fold 80% vs 3bet in MP OOP.

Betting is obv standard but I don't think I have a lot of FE on this flop, they both have 99 - QQ in their range and it creates deception when I hit my hand. I like my check here.

Ok, here it becomes interesting, I don't think OR is bluffing a lot here (I block nutz flush) so his range is probably pretty strong (DP, sets, straight, flushes, maybe JJ/QQ)
Cold calling in this spot is so ridiculous because I don't really see a hand I would play like that but shoving looks also really strong. The good thing about calling is that I can keep the fish in, and the good thing with raising is that I don't really rep anything except maybe 78 and 66 but I'm probably not raising when the flush hits.
It could be fun to click it back too, he might think it's a miss click :D
