Ethics question... fire out that extra raise? (crosspost from SSLHE)

[dtbog]

Setting: 3/6 Hold'em at Turning Stone. I sit down while waiting for my NL seat, and I instantly remember why 3/6 at Turning Stone is so profitable. No one else at the table seems to know anything about poker, except for maybe one other college kid to my right.

I go half an orbit without playing a hand, and in this time, an old lady sits down across from me. She clearly doesn't know what's going on, and as her husband hands her a portrait of Benjamin Franklin from out of his wallet, I can see the eyes of my table-mates lighting up.

Anyway, I'm involved in her second hand at the table, as I raise preflop with my AK and get two callers, one of which is this woman (who I'm not sure knew that she could fold).

Flop comes AJ8. She bets out, clearly confused. I raise (simply for the purpose of forcing out the third player in the pot), button folds, old woman calls.

Turn comes J. I'm no expert hand reader, but as the woman throws out her $6 bet I know she didn't make any sort of hand. I contemplate raising, but consider that I have to live with myself at night. I call.

River comes 8. OK, so she's probably playing the board at this point, and I have top 2. She bets out again. I again realize that getting another $6 out of her will not make me a better person. I call.

I table my aces and jacks, king kicker. She tables her 79o, for... the board. The dealer instructs her that "check" means that you pass the action to the next player without betting. She seems appreciative of the new advice.

My question: how many of you put in the raises? Note that we're assuming that you know she doesn't have a jack or an eight.. because, well, we do know. It's certainly a negative EV play to call behind on the river, say.... but do you care about the fact that this lady obviously doesn't know how to play poker?

Personally, I don't see any need to take her money... but then again, I'm not a pro who is counting every bet, and I'm not even a regular player at this 3/6 game. What do you pros think? If you're couting on BB/hr from this table, do you feel better about taking her money?

Opinions welcome.
