deepstack 25-50 hand vs jcmoussa

[TStoneMBD]

25-50 at foxwoods. jc has about 17k and i cover. he seems very good but is on the tighter side whereas i am on the laggy side.

hes been wanting to repop me preflop for some time now and i feared that if i folded it would open the door for him to do it regularly, forcing me to tighten up and play less profitably. i thought there was a good chance he was light. i also thought because were so deepstacked and i dont mind coinflipping for stacks on a draw it would be ok. in hindsight however, because were so deepstacked maybe calling with a suited ace preflop is a bad idea? i cant imagine getting all the money in on a coinflip with these stacks. all that will end up happening is ill be calling bets OOP with a draw against a player who reads hands well.

i openraise Ac8c from MP2 to 200, jc repops to 600 in CO, folds to me i call.

flop is QJ3r

i check, he checks

turn is an A

i check, he bets 800, i call

river is a J

i check, he bets $1600

what % of the time should i call this? hows the hand up to this point?
