Just call preflop don't 3b.

Ap call, he can have worse kx and if he backdoored a flush good for him.

I changed my 3bet ranges since watching the vids on here , now 3betting a'lot more KQ AJ type hands ip. Maybe i'm getting the ranges confused or missing something

3betting pre is fine. On the river, what are we afraid of? I know we have far from the nuts, but AK is unlikely, and the flush that came in is backdoor, so a hand like AThh isn't usually calling the flop. He easily could have us beat, but just as easily have a missed diamond draw, even straight draw or a worse king.

If I'm V, and I know it's micros and I don't know the tendencies well, but if I backdoor something I shove. You showed strength the whole way, he has to think he'll get paid in full. I think we're ahead plenty here, certainly more than the 25% of the time we need to break even.

9Th 56h J9h TJh would make sense , i'm just not sure people donk missed draws like this on the river and worse Kx usually check call , whats he hoping to get called by with this line ? I folded so a bit confused.
