Sanity Check

[Kurn, son of Mogh]

Typical LP low limit HE game. Here's the situation.

Hand 1: You're on the button. Player in MP2 open limps, folded to you, you raise, blinds fold, limper folds.

Hand 2: You're in the cutoff. Same basic situation. Same player as hand 1 open limps, folded to you.

You have ATo (I think cards are somewhat irrelevant - so any mediocre hand you might consider playing with position)

Question: Is there any rationale at all for not raising?
