If insurance at +3 is a good bet, then should I be insuring other player's bets? I was back-lining a player when the dealer showed an ace at TC 3+. The player didn't want insurance. He had $25 up, and I had $75 behind him. I was going to insure my own bet for $37.50, and was getting change when the player said to just put down $50 for both bets. This got me thinking. I could make money by insuring other player's big bets at +3 or higher. Would this seem suspicious? I've never seen it done. Technically, it wouldn't be a problem. I'd just hand over the chips to the players and ask them to buy insurance for their bet. Anyone actually do this?
