but if you're asking whether you should call or fold, i dunno, flip a coin. most people will have air a lot here with his size bet but the AJ hand before makes me think he value bets thinly. there is a huge difference though between value betting thinly on turn (when there are draws to protect LDO!) and doing so on the river with AA or KQ on a monotone board, so i'd be inclined to call and then take a note of what you saw.
