I was pretty sure my opponent had something like 55-TT, AQ, AT, A8s-A9s after he checked to me on the flop. I feel like normally my hand is too strong to check back the turn, but what swayed me towards checking this time was that my read on my opponent was that he would fold everything in his range except for AQ, AT, and A8s or A9s with a FD (and he might even fold AQ and AT with no FD if he's tighter than I think he is on his call-downs). But I felt like he would call a river bet with pretty much his entire range if I checked the turn since my line would look like a bluff. And since I have a FD, I don't hate giving a free card since it will often help me. Without the FD, I would bet the turn since it's more likely my opponent has 6 or more outs and I'd want to protect my hand.
But maybe this is a very standard turn bet and I just over-thought it?? If so, what would be a good range to check-behind assuming that I bet the flop with any pair or better (with TT+, KJs+, and AQ+ not being part of my range since I cap with those in position preflop), as well as OESDs, FDs, and AT as semi-bluffs, and also my very worst hands (76s, 65s) as pure bluffs? (And now that I've come up with a flop betting range for myself in this situation, I would also welcome any feedback on whether this range is okay.)
Thanks for any advice.
