The Ultimate Fish - Morally Wrong?

[MRBAA]

He's in a casino, at a table, with chips and able to play. I'd play him but do two things different than I would against a non-mentally deficient fish:

1. Try to make the experience enjoyable socially to the extent I can (ie. chatting, being friendly)

2.) Checking down head up (I can afford to donate a little EV to let him have a little more fun time at the table).

Other than that, it's poker as usual.
