Should I bet flop or turn to protect my hand? I think checking is best on flop but once it checks through again on turn I think betting is best to protect my hand and get value from 8x and draws.

I'm not betting this flop. Too many draws and too many players.

Turn is okay I think, especially with the double flush draw.
