I am not sure what line here would be correct. At the game time I chosen check-calling, but I have doubt that it was optimal. I think I should have raised the flop, but what is the plan after that? If I reraised, am I folding this? If called, and then checked on turn, am I betting? If I check behind on turn, what bet amount I call on the river?

I like how you played it, he may think his aq/aj is good. Raising the flop prices out flush draws, is he the sort of guy who calls with AQ/AJ, if so then I like a raise, if not then c/c is good.
