MTT - Bubbly draw decision

[franknagaijr]

Stars MTT 68 players, down to 12, payouts start at 9. The limper was a hold'em mentality who didn't seem to distinguish starting hand values at all, and the raiser had made enough moves that I assumed he was raising a little light. As with all stars payouts, the real money is in the top 3.

Thoughts on the preflop and flop decisions?
