Pre flop and flop are both pretty bad. When you complete with A2 out of position what are you hoping to flop?

Then a nits nit raises you on the flop and calling even 2 into 12 is goofy as you are hoping to be drawing to 3 clean outs.

If you want to play for stacks on the turn, crai.

Reread the hand:
- Hero is in the BB. He just checked his option.
- The flop raise is an all-in from the short-stack donator, not the nit.

As to the OP's hand: I'm with the crowd that doesn't like the flop lead. OOP, A-hi flop in a 4-way pot, we're not in very good shape with top pair, worst kicker. The 2 diamonds also make it tougher to play because we'll never know if callers are a better Ace or a flush draw. As played, once the nit calls MP's raise, I'm done with the hand. Even though we may be getting good immediate odds, we're out of position and our reverse implied odds are looking pretty bad.
