    The most common strategy mistake I see is the splitting of 10s. Even against a 10 or 9 face, people split 10s over and over, even after busting out the split or drawing low cards.

    What do you guys see a lot of?

    My friend, this may not be a mistake.

    Not doubling an 11 against a dealer 10 is the mistake I see from ploppies most often. Splitting low pairs against a high dealer up card is also common.

    How about double any soft hand vs. any "bust" card. I see people double A3 vs. 3 all the time. Although they would never double A7.

    By far the most common. Standing on A7 vs 9 or X

    A, 7 gets my vote too.

    And failing to double when appropriate.

    Where one earth are you playing that you see this mistake so commonly? I almost never see it American casinos, though I saw it often in Asia and Oceania when playing there.

    Most misplayed hands are (1) Soft 18 (almost never doubled or hit); (2) over-doubling of soft hands (e.g., doubling Soft 13 vs. 3); staying on 16 (not just versus a 10 but versus a 7 -- many idiots are more likely to stay vs. a 7). There are others but they are close calls anyway (16 vs. 10, 12 vs. 3, doubling 11 vs. 10, etc.). Many people also never split 6's, 4's, or 2's.

    I'd have to say standing on stiff hands (usually 14-16) vs. 7-A.

    I'm fairly new to casinos so my perspective may be a little off, but I saw this happen fairly frequently on 2 consecutive occasions at the MGM Grand in Detroit.

    The biggest mistake I see,but not the most common,is the "all-in bet",where someone gets frustrated and after losing half their bankroll chucks it alkl in in an attempt to break even.Its amazing how often this produces a hand that requires a split,a double down or results in a dealer BJ.
    Standing on A/7 might be the most common,but I rarely notice how players play their hands. I notice their bets much more.

    But this is when we jump in and offer to double it for them. Or split those aces.

    Next must be standing 16 vs 7. It is not even a close call.

    Top Ten Common Mistakes by Beginning Blackjack Players

    Here's my personal take on beginner blackjack errors:

    Top Ten Errors Made By Beginner Blackjack Players

    10. Not hitting with 12 when the dealer shows a 2 or 3
    9. Not hitting with soft 18 against a 9, Ten, or Ace and not doubling against a 3, 4, 5 or 6
    8. Not doubling a 10 or 11 when the dealer shows nine or less
    7. Not doubling a 9 when the dealer shows a 3, 4, 5, or 6
    6. Not doubling soft 13 through soft 18 hands when the dealer shows a 5 or 6
    5. Not splitting 2s, 3s, 7s, 8s when the dealer shows a 2, 3, 4, 5, 6, or 7
    4. Not splitting 9s when the dealer shows a 2, 3, 4, 5, 6, 8, or 9
    3. Doubling for less
    2. Taking insurance (when the count does not justify it)
    1. Splitting tens

    Doubling and splitting errors are often the most costly mistakes for a blackjack player because both decisions involve increasing the size of the original wager.

    I think it would be interesting to analyze not only which errors are most common, but which errors are most costly. In other words, what is the frequency of the error * [EV(correct decision) - EV(incorrect decision)]?

    nuvi, just out of curiosity, are those rankings your personal opinion, or actual data from your site?

    Not just interesting but perhaps even necessary if you are a CC wanting to make some camo plays designed to make you look like an idiot. It wouldn't be hard to pick 4 or 5 plays you could misplay every single time and it still wouldn't cost you a hill of beans, say a nickel for every $100 bet, but at the same time would have every BS player at the table convinced you're a ploppy.

    Might be a nickel well-spent if it buys you longevity.

    Of the ones you mention A,7 vs A would cost you almost nothing. 2nd would be A,2 vs 5 also costing almost nothing.
