If you call, pot will have $2.25 before turn card. You will have $1.04 behind.
Unless turn is a A for you to fold more easily, or a K to put you miles ahead, there is absolutely no difference. You are behind what you are now, and ahead of what you are now.
I can't fold that overpair in NL2, so I shove, instead of waiting for villain to put me AI.
I understand that by raising I can arguably throw away opponent weaker range and keep only the range that beats me, but honestly, does anyone doubt villain will do that move and call with TT, JJ, AQ, KQ, QJ? I'd rather pay his set OTF, than allow him a free J, T (...) on the turn, or even a 9 for str8.
Not that it matters in zoom, but if you are going to fold every flop where you have an overpair and vaillain raises, you'll be quite exploitable. In regular tables, usually there are notes, but I need very good notes and slightly messier board to fold that kind of hands.
