Top Pair

[Overseer55]

Tough decision. I would expect the limpers to have nothing, but the BB to have a weak ace. I would raise now planning on 1) possibly folding the flop to more aggression, 2) betting the turn & checking the river unless something interesting happens. If BB has something like A4, you will be chopping almost all the time. Ideally, the flop would have been AQ8, which is much better for chopping than AQ5.

BTW, fold pre-flop, you need more than 2 limpers to make A2s profitable.
