I think folding the turn is bad here. AJ is the most likely holding and you have 8 outs to chop and 3 to win. I also think that this type player is calling all suited aces preflop and raising them maybe 50% of the time on this flop.

Bet folding the river agaisnt this player seems best since I do not think he is raising a worse hand. Check call is OK.

SO, I think folding the river is better than folding the turn. But, I think you are good enough here for the river call.
