NL100 PF BU AA, river decision

Pretty clear value bet if you used min-raise sizing PF. He would have a ton of Q2o+ combos. some of which will be forced to call the River. Since you 3Xed it here, his PF range is gonna be significantly tighter.

Way too thin, given the Turn card. You only have 1 more street and you should either b/f T or ck T bet or call R.

Of course maybe he raises the Turn with some straights or sets but your equity probably won't rise above 70% and you would only be able to make a really small bet anyway.
