Hmmm...

My intuition says a true expert should be able to exploit situation (D) to his advantage. If he knows you know his cards, he will be able to gain valuable information about your hand that he can then exploit.

Example: Expert has QQ, the flop comes AK6 rainbow. Let's say you bet, QQ raises, and you re-raise. Now, since he knows you know his cards, he can determine that he most likely has the best hand. If you had an Ace or a King, you probably would have just called to let him hang himself or get another bet from him on the river.

These situations can come up fairly often and since you have amnesia, he can exploit them over and over again without you knowing it.
