c/f the flop. c/f the turn. It wouldn't be 4 outs at "best" it would be 6 (the four 5's and the two other Jacks to make the nuts) (but getting 2/1 to draw to an 8/1 shot is not the kind of thing I like to get involved in)

Why c/f flop? We have top pair and OESD on a rainbow flop.

I check call flop. That way pot is smaller so we can call turn as well

Ya, good point. If we check flop and co bets, we'll be closing the action (which I overlooked) so that would make it a call.
