Suppose it's just another day in the green felt jungle where you're playing blackjack with two other ploppies -- nothing new. In a modestly positive count, you double A/8 against a 5 and catch a 10. The dealer turns over a 7, then hits it with a 9 to make 21 and sweeps the board. Seeing that your 10 would've busted the dealer, they both begin to chide you for your shoddy play.
Next shoe with a slightly negative count, you hit 12 against a 4 and catch a 6. Already perturbed over your last "rulebreaker", they again throw their arms up in protest even before the hand is played out. The dealer turns up a 5, then a 10 for 19 and sweeps the board again -- when it would've been another dealer bust had you stood on 12 vs. 4. Mere admonishments now become insults of, "Can you believe this guy?", and "That's gotta' be one of the worst moves I've ever seen!" But hey, you're used to it -- you absorb this kind of abuse every day.
Next hand, you get 7/7 against a deuce. You know your best play is to split, but even then you'll win on each 7 only 46% of the time. So with a puzzled look on your face, you quizzically ask the pseudo-experts, "What are you supposed to do with this one?" Never short of advice, one quickly decrees, "Split'em in a heartbeat, Man." The other jumps right in with, "Nothin' to think about -- a textbook split." Looking unsure, you ask if somebody wants to take on of your 7's. Thinking that since it's a basic strategy split, they both jump at the notion of getting part of a "moneymaking" hand from some goofball who doesn't know any better. So you sell each of them a 7 and get out of the hand altogether. What's your moral opinion of what you've just done?
