KK+flush draw. Some basic postflop questions

Thanks for the responses.
With my stack it seemed natural to push but then thought that would make it easier to fold so I bet 30. He instacalled with AsJs.

Thinking about it now, his call is so bad that I shouldn't be expending much effort on this but at the time I thought he could call with an ace if I didn't bet too much. What surprised me that he did it instantly which got me thinking I could have bet more.

What has struck me recently is how important getting these river bets right is because the amounts involved are so big.
