9h7c in SB on PP ???

[BB King's]

Paradise: $1/$2

I'm in the small blind w/ 9h7c - I complete behind 3 limpers. 5 players see the FLOP: [ 9c 7s Th ].

I bet - only 2 of the limpers call. The TURN: [ 9c 7s Th ] [ 4d ]. I bet - they both call.

The RIVER: [ 9c 7s Th 4d ] [ 4s ]. Now what ? Would you bet the river ? I did ...

Any comments appreciated !

Thanks, BB King's ... formerly known as the pokerplayer formerly known as Jack
