can be offset with this hypothetical scenario. You bet 25 dollars and get an 11 against a dealers 6. The double nets you a picture. You have an unbeatable 21 with 50 dollars bet against a 6.The guy next to you offers you 10 bucks for the hand(ie he offers you 50 dollars for your chips on the spot plus 10 bucks for the pleasure of getting the result of the hand). So you are guarnteed 10 bucks as oppossed to a chance of winning 50.Silly huh wht if it was 20, 30, 40 , 45 etc.. It would be a math decision just like insurance is a math percentage decision. Blackjack is about odds in different circumstances adding up over time. Its possible for instance that doubling 9 vs. 4 has cost you money in your life but your lifetime results of doubling Ace 5 against 6 may be higher than it should. The hucksters like JP harp on short time for select plays when BJ is the sum of all plays that occur long term. A nickel saved here and there adds up just like a nickel lost here and there adds up.
