Live 1/2NL what would you do?

[dr. mindbender]

small stakes, no limit game blinds $1/$2. a very interesting situation came up in my tuesday game. action Pre-flop was passive.tricky lag in early limps, two women very tight, solid players,i think gender is very important in this case and in no way am i trying to be sexist, limp. coincidently they are sitting right next to each other.lets call them the rock and the boulder. lap in the small completes the blind. Action comes around to yours truly, the big. i have a 56 in spades. Now the session is winding down and it's at the tail end of 5 or 6 hours. i check. Flop comes 7h,Ac,8c . pot is $10 bucks small checks, i bet $10, tricky lag calls, the rock and the boulder both call. Small folds. The turn breaks my heart: "9d". All hell breaks loose. I have a straight,nine high. how ever any "j10" beats me. Remember this is an unraised pot. I bet half the pot ($25). let's see where i stand? tricky Lag folds, the rock, raises $50, the boulder calls $50. Pot has now ballooned to $175 and both players have at least $150 in chips,i cover them both. I have a straight albeit on the donkey side, with the two tightest players at the table raising and calling behind me. the board has a higher straight out there as well as a nut flush draw. what should i a have done.
A. Call
B. fold
C. Gone all in
D. call a doctor
I have the out come on my next post after i recieve some feed back from the forum.

thanks
