An 'image play' in a won pot

[deadmoney98]

To the OP...I don't get it. Why will this confuse or irritate your opponent?

If he is as bad as you say he is only playing his cards, and now has K high or something and does not care about insta-mucking.

If you are so sure about his hand I think it makes more sense to bet some very small amount that will shame him if he folds to such a small bet, or calls and shows junk.

Also, bet more on the turn (as much as he will call with an inferior hand).
