$5NL 6-Max, whiffed AK OOP against unknown bigstack

[Wooden Ta Sheng]

I haven't been at the table long but UTG was berating villain for calling a raise with only a draw and then winning a big pot from him on the river. Do you c-bet this more often than checking and if so, what's your bet size? If you do check, how often will you attempt a c/r bluff (if at all)?
