What's your line here? ($10NL)

With A6s on the button I just call although perhaps a raise would be a better play? On the flop there is a bet and a raise, I could re-raise but I want to keep flush draws in as they are drawing dead so I just call. Make sense? On the turn I'm beating all the aces and draws, only losing to 23, 37, 78 or a set and I still have the nut flush draw so I put in a big raise. When the SB goes all in and CO calls should I push or just call as I did?
On the river will CO really check a set or str8? Should I value bet?

CO checks, Hero???

too much reraising going on. CO I think has just a pair of Aces
I am worred about SB with a set, its a weird line to check on the turn and then re-re-raise it.

I check and call a small bet. at best SB has 2 pair. at worst its a set. or even a straight, and who knows, CO might have A7.

Thanks Beck you are spot on about the CO he had A10, bit suprised he didn't fold the turn. The SB turn line threw me as well, turns out he was drawing to a flush... So in the end a good result for me but it was a scary hand, if SB had been fullstacked a turn push would have been tricky.

Push the turn!!! even if u were scared that CO had a set, you gotta believe if ur 6 or A hits ur FH is good plus u got the Nut flush draw; SB no longer matters to you on the turn... this is playing scared seriously, there's cautious and then there's too damn cautious... this was the latter!!
