54$ 5m 78s

Pre - looks good.
Post - I play it the same, though it's close. If we are against 1 overpair and 1 flushdraw we have 43%. If against a made straight and overpair, 17%. If vs a set (66) and flushdraw, 18%. So we're rarely along way ahead.

If no flushdraw I probably fold still. More likely to up against sets/straights etc.

Both regs: trivial fold imo.
Both fish: i call; we might well see 55 and 67!

I still call given who we facin'. If no FD, I fold to that action with a fish reg involved.

Edit: on a second thought, maybe fold is better this deep.

i cant fold it with your reads on the SB. we dont care about the BTN. i think the SB can even get it in here with A8, as well as all teh 2 overs + spades, he still has 86 and 67 in his range. i think if you had bottom 2 it would be a little easier to justify a fold (i probably still cant do it) . the pre-flop action wouldn't be correct if they are both regs, but for argument's sake, on this board if you have top 2 vs 2 reg's AI i think its going to be a close fold this deep.
