Stack and bet sizes? How much is in the pot and how much does the shorter stack have left behind? How big are the blinds? Buy-in? Does he look like a donk?
As written, this is kind of like posting:
Someone limps, I raise with 2 cards. Flop is 3 cards, I bet and he calls. Turn is a blank, I check, he bets and I push.
Ok, maybe not that bad... anyway, the better I got at this game the more I learned to pay attention to details.
