Deep stack situation in 50NL

[paperchamp]

SB is a pretty big LAG, BB seems fairly tight and aggressive. My problem with this hand is that I called the flop bet planning to push on the turn but then his turn bet screamed to me that I was beat. Does the fact that the table is somewhat deep stacked change the way you play this hand?
