What possible reason do you have to believe that BB has a 9.... well I suppose you didn't raise enough preflop given the limper but even so.

If you fold big PPs every time the board pairs or you flop 1 over you are losing value.

I would only consider checking this flop to induce a flop so I could happily get allin on the turn. On party $11s the stacks are just not deep enough to avoid getting allin on hands like this. Just push the flop. (Edit: and raise more preflop)
