I make a point of never playing two-pair from the big blind for my stack in an unraised, multi-way pot.

Stabbing at the flop is good. But after that I think you should fold to the raise to $22. The few times you give up the best hand are compensated by all the times you avoid paying off a set.

Edit: 13/8/2.5 over 500 hands is pretty nitty for the $22 raise, too. More reason to let A6 top 2-pair go when he raises.
