Given that you got called by the short stacks I don't think your fold equity is high enough to bet the turn. I would just check and hope for a free card or cheap enough card

I knee-jerk reaction to flopping a straight+flush draw is to bet the flop with plans to 3-bet all in. But seeing as there are 6 players to the flop, and 4 still left to act, I am pondering a check/call instead. I definately don't like a checkraise all in, unless it's only against a short stack.

But yeah I'm torn between a bet-3bet and a check/call on the flop. I will do some soul searching...
