Pre + OTF fine.
The c/c plan OTT isn't bad because as you've said yourself the spr is pretty bad to b/f into, and an A (carrying FE) in conjunction w/ a double barrel will fold out most worse made hands a ton obviously, so b/c kinda sucks to. This villain is also Solid-Aggressive so u can't always rule out some kind of crazy float OTF, so u want to give him some rope instead of push him out w/ another bet into a huge pot OTT. Also, I'm not always assuming just cuz his stats are good hes some dynamite hand reader, so I don't think checking gives your hand away at all....it simply gives a possible floater/aggro player rope and mimics how u might react when the A is a scare card for you as well...
When he checks behind OTT were probably ahead most times as hed of fired if floating, and the hand would've worked out fine if u didn't get rivered iyam.
But I suppose b/f might not be a disaster cuz I'm not putting him on a bluff all that much, and b/f into any sized big pot doesnt matter if ur like 100% sure hes not bluffing, even if it stings.
So...in short...idk what lines best actually
. flip a coin.
