Argument 2.

The second question of the last scenario is exactly equivalent to "show me the ace you've chosen", which gives zero new information about whether you have two aces or not.

But Argument 1 has an intuition pump based on equivalent states of knowledge, too, and it's wrong! ;)

This equivalence works but does not generalize well, as it would fail on a three As two 2s variant.
