Here's my take on the whole thing.....

Something's wrong with the equation. A big blind that never folds preflop, but always folds postflop when an ace hits? Those are two absolutes that just don't go together for the same player. Anyone who's loose enough to defend their BB unconditionally will play past the flop in situations that a TAG wouldn't...bottom line.

Limping on the button with Ax is pure suicide and I don't care what any books say about it. If you're going to choose not to raise ONLY to compensate for the times you flop an ace and they fold, then I can think of a zillion other 3-outer situations that are suited for you.

If you play your button correctly and your range is big enough to include 75% non-ace hands, then why doesn't this make sense:

If the loose guy folds to an ace-flop 100% of the time, he's making a MISTAKE 75% of the times that you play your button correctly. Wouldn't you want to encourage that?

Just my thoughts.
