small blind plan

[theGorn]

Hi,

50 NL on party. 7 players left. At 30-60 level I get A /images/graemlins/heart.gifJ /images/graemlins/heart.gif in small blind. One limper in middle position with about 700 chips. I have 850 and BB has over 2000. I just complete hoping to hit hand and get some money out of the middle position limper. (I have no read on him). Pot is 180.

Flop A /images/graemlins/spade.gif 3 /images/graemlins/diamond.gif 4 /images/graemlins/club.gif

I check hoping to trap and middle position bets 240.

Uh oh. Did my plan backfire? Am I outkicked or is he bluffing?

Call Fold or Raise? If Call, what would I do on turn?

Thanks
Jeff
