After 2 street just call i expected either fd or top pair but doubt he would call kj or qj pre, so i pretty much expected the exact hand he had, but can we fold this ? I know once i checked fold is more legit move because he will call lighter then open on the river. Both draws busted might be enough for 25% but i am just guessing.
Check/fold sounds right against him.
