Feel like I'm being levelled by the first one. "He can't be creative post flop" and the fact you posted it makes me wonder if you think the standard "fist pump call" isn't right.

His line might be nutty (and if it was, surely AK, and KK play the same, equal combos make that 50:50 and #lolpotodds), but isn't overbet shoving the river with the absolute nuts slightly creative post flop? If not creative, it's certainly a very good EV maximising play against a normal player's calling range. I'm reluctant to rule out TT, AT, A8s). Call the first.

Second hand b/f like 14. The f because he's got you beat if he raises and the bet because there are only 6 realistic sets he can have on the river compared to 8 AQs that might call a bet. With the Ah gone, he can't have many draws and won't bluff them anyway if he's not creative.

This becomes a check fold if there is a reasonable probability of him folding AQ to a river bet assuming he'd check it behind you
