There is already a ton of responders all saying raising big pairs is EV+, I concur. Time to move on. I would not even add my vote to the landslide unless I felt I could mention something that has not been touched on by the other responders.

You hit the nail right on the head about making a note of who these players are. Live, there is a significant number of "old school" regulars who play low LHE at Commerce NOT raising big pairs PF. While this play is WRONG, take note of who plays this way. They play this way VERY CONSISTENLY. Be careful when you are in and hand with them, particularly HU, and they quietly hang around. They (generally) are not stupid in their post flop play. Your TPTK may not be good against them if an overpair could win and they are in the hand. They LOVE playing a stealth bomb. Know your opponent. IMO, average age, 60+. Average length of time as a player, 10 years +. Weak tight personified. I think I can point out almost all the 2/4 regulars at Commerce who do this, and most of the 3/6 & 4/8 players who have this habit.

I've posted before that I often do raise not AA from UTG only. Since I usually play the fewest hands at the table any raise tends to get more attention and it lets the field know that I do not raise every quality hand every time. Just as once in a while I would raise with a lower quality hand just so there is always a degree of doubt in my opponent's ability to put me on a hand.
