$55 BB hand

[rybones]

how do you play this flop? I had no notes on the three others in the hand. As it was early in the tourney the only read I had was that they all had limped more than twice already, but they did not seem like donks.

Seat 1: sb (1020)
Seat 2: <font color="red"> hero/bb (700) </font>
Seat 3: mp1 (2130)
Seat 5: mp2(925)
Seat 6: mp3 (1075)
Seat 7: mp4 (2265)
Seat 8: co (1005)
Seat 10: button (880)

sb posts small blind (15)
hero posts big blind (30)

All fold to co, button and sb who all call. Hero checks in the bb with [ Ad, 3d ]

Any thought appreciated,

Ryan
