Thread: Splitting TT vs 6 drew PB's attention

    Splitting TT vs 6 drew PB's attention

    I played at local casino as usual, and running count went up to +10 with about 1.5 deck left. So TC should be 6 or 7.

    I got a K ad J vs dealer's 6. So as usual I split according to the deviations (TC>=4).

    What happen was that after splitting I got T each time until MAX 3 splitting to 4 hands reached. Then dealer flip the hole card of T and then took a 9 busted.

    My initial bet was $300 and then $300 for each splitting hand. So dealer gave me 4 stacks of 3 black chips to each hand that I won.

    This time Pit boss came over with a lovely smile face and said " congratulation " to me as if he was very happy.

    I knew he was upset. Maybe he was thinking whether I was a counter.

    I left immediately after that shoe.

    If I did not split TT then I should still win. However just one hand of $300 instead of 4x$300.

    Do you guy think it worth to split Ts against 6 ?

    There was one split hand of T got Ace. If I doubled that hand I would be able to win even more.

    I don't split Ts. It's too obvious. I would rather earn a bit more slowly than get a bunch of money and get barred.

    Is this a local place that you want to be able to keep playing? If so, don't do it. I suggest you not play that shift for a while, so hopefully the PB will foreget about it.

    Not advisable to split 10's unless the count is obscene (I'd call +7 pretty obscene) and you're about to leave. Mathprof (RIP) has some good articles in the BJ21 archives. Waiting until +7 you get the lions share of the EV from the TT splits but do it far less often. That said if you really value a casino and the game is great and tolerant you may want to refrain from doing this play unless you have already cultivated a wild image by splitting 10-10 incorrectly.

    Bigplayer - suppose you use +7 as your threshold for splitting Ts. Say there's one deck left, you split and get another T. Wold you split again, now that the TC is less than +7?

    Definitely yes. Keep on splitting until you're at the regular index. You've already made the pit mad with the first split, might as well get your moneys worth. The whole point of waiting is you're more likely to get those resplits.

    Makes sense. Thanks for your wisdom.

    Maybe I’m right, maybe not - I wouldn’t keep splitting till strike point is reached. At RA7 and above, lions share of EV is reached. Each subsequent split below RA 7 catches a lower percentage of EV until you reach a dangerous +4.

    I recall a particular a big bet 10 on 10 double at RA 8 or so, catching a stiff - not pretty. I also recall (red chip days) a couple of 10 on 10 doubles at table max of $50 each catching a stiff, each winning. The point is, regardless of how rich the deck is, anything can happen.

    That being said - it’s a game of decisions - regardless of winning or losing any particular hand, making the right decision all of the time wins you the prize. What’s right also means that 2 different players simming their own unique circumstances may well make the proper decision each different from the other on the same hand.

    10 vs T may not be the best comparison. This play is particularly sensitive to risk near the EV-maximizing strike point of +4 and using +7 as the RA strike point is worth more than knowing all other risk averse indices combined.

    T,T vs 5 and 6 are no nowhere near as sensitive to risk and the advantage rises very quickly beyond their respective strike points. In fact for 10 vs T, EV only rises at a rate of about 1% per true count at +5 and +6. For T,T vs 6, the rate is close to 6% per true count at +6 and +7. This dramatic rise in EV is more than worth the extra mathematical risk if you have already split and exposed yourself to the risk of heat.

    See my original post "RC =+10 with about 1.5 deck left."

    It only took two more Ts after the initial splitting to max allowed number of splitting, then no more splitting allowed. The running count was 9 for me to make last decision whether or not split TT again. At the time, the number of remaining cards in the shoe was slightly less than 1.5 decks

    +9/1.5=+6

    TC was far from below +4

    The deviation I played should be correct. My only concern was PB. PB only came when some other guy won
    thousand+ dollar on side bet and it was dealer who called him. For me, dealer did not call him, however he came over to say "congratulation" me.

    1. You mean far above +4
    2. Point of interest here. You floored to +6. I prefer to interpolate which would raise the actual true count. Sizzling deck. Your technically correct play was in fact the max split. My prior comments were based on a reducing tc down to strike point.

    Same thing. He meant that, even with extra tens coming out, the TC was nowhere near being below the strike point of +4.
