Hi guys. I just played this hand at the final table. In the hand I am chip leader and am being squeezed by the second chip leader. The payout structure is as follows:

1 $675
2 $487
3 $369
4 $275
5 $188
6 $157
7 $126

The opponent is 33/31 with a 3-bet of 8 over 37 hands, so no real information. I don't know anything else about him. My question is: Are you guys defending here preflop given our current level of information?
