A "Scavenger Blackjack" technique
I have "back-lined" some as a wonger. I try to go for a small bettor, as s/he will almost always defer to my playing decision if he has a $15 bet and I have a $200+ bet riding. If his (incorrect index-based) play is a costly blunder, then I simply buy the hand from him, at a small extra cost, "locking in a profit" for him, if need be. If the hand is an obvious net loser I buy his hand for whatever he has bet or I toss in a $5 profit. He will be pleased to make money on a bad hand. If the hand is an obviously powerful play, I increase the incentive money. Sometimes, when the error is egregious, e.g. The hand is 11 and the dealer has a 6 with the ploppy afraid to double. I make his hand an automatic winner by insta-paying him, (as if he has just won), while seizing ownership of the hand. More often, if there is a huge difference in our bet sizes and the count is positive, I'll tell him "If you double and you lose I'll reimburse your (piddling) loss.", thus guaranteeing his win. He will jump at it and thank me later. Thus I gain his respect and he will defer to you thereafter.
