A weird situation

[Nick B.]

7 people left with 50/100 blinds. The big blind the previous hand busted out so there is no small blind. The current big blind has 5 chips. It is folded to me in the CO with AK and a 2600 chip stack. The button has ~1200. I probably made the wrong move, but there is no pot to win really. Only 5 chips in the middle. I think I should have just folded. I ended up calling and beating the BB out of his 5 chips.
