Interesting points Ben, although I"m not sure I like folding to the 3bet pre vs a likely button steal and a possible light 3bet. Having said that, my other options don"t seem vary appealing either; how about if I were to cold 4bet small to say 1075? Obv folding to a 5bet would be turning effectively turning my hand into a bluff, I think I"m ahead of their ranges at this point, but pretty crushed by a 5bet vs my cold 4betting range. I guess what I"m saying is, is it ever ok to 4bet for value intending to fold to a 5bet?
As played shoving 200bbs pre over a 4bet with JJ seems a little spewy to me, so I guess folding to the 4bet is best.
I"m pretty sure that dan just took me as a random, as we"d never played before, which imo makes the turn more tricky as he would never expect a random to fold an overpair at this point. He"s obv cbetting the flop 100% of the time imo, so would he really fire 2nd and likely 3rd barrel with bluffs that he could 4bet pre with, like AK after me calling on the flop and the turn really changing nothing. Like you said, the turn is a great card for my hand, and dan must know this is likely a great card for my range, so would expect him to shut down with hands like AK as firing a 2nd barrel would be such a large % of his stack, and would prob be committed to follow through on the river.
Fwiw, I like check shoving the turn, but would be lying if I said that the fear of busting that early didnt at least contribute a small part towards my decision making
