Pre-flop bet sizing is a bit messed up due to HH converter not recognizing FTP Rush but it was a $0.50 min-open.

I considered squeezing but decided to take a flop.

Flop: I decided to donk lead here because I don't think CO will always cbet here 3-way. Plus I can build a pot if he raises, which he does. I block 77/AA/97s and my line just looks hella fishy so I think he even bluff raises here sometimes too. I think his range for doing this is AJ+, 99/77/AA, A7/A9/97s, most diamond draws like JTdd, KXdd. Once I 3-bet I think he folds all his air and jams all of his sets/2 pairs, which leaves flatting with big aces like AQ+ (probably with a back door diamond) and anything diamond draw.

Turn: I think most of his big TP ace hands with backdoor draws will likely take the free card since I could also easily have had a FD and he risks getting CR'ed off his hand. All of his flush draws remain and he would play them all like this. 

I'm really unhappy about check/folding here but I think I have to? From a "GTO" perspective I think I would also lead with 77/99 here and the same turn would bring me lots of pain. Maybe this is why donk leading is bad? Some perspective would be nice, thanks.
