I don't like the turn barrel with the AQ in the second hand. He has 24 combos of 77-TT, you only have 70 hands on him I think which means he might flat AJo here especially with the ss'er in the bb, and he might call 77-TT on the river anyways. I think best case scenario is that river barrel is slightly +ev and it's lighting money on fire otherwise.
In villain's spot I flat 88-QQ, AQ, AJs, KJs, QJs pre. On the turn I'm folding 88-TT so once you bet a brick river I can't fold anything. So if villain's tight I think it's stretching it to bet turn+bet river. If villain's looser I think there too good of a chance he doesn't fold TT-, Jx, or he has AJo in his range.
