11r 45k blind vs blind hand

[future]

Everyone had been playing tight and I was stealing blinds, but it wasn't too obvious. I figured I would pick up the ante >50% of the time here. Protecting my hand on the flop and calling given the price standard here? I was the chip leader in the tournament and losing the pot drops me to somewhere around average.
