split 8.8 vs 10 At high count

#1
Hi guys

For s17 6d game

Wong says split 88 vs 10 at <=+8 , whats the surrender count。 also do you really split 88 vs 10 or Ace at a extremely high count with your max bet if surrender not avaiable

Thanks alot

late surrender 88 v T is +1 IIRC. There is probably a case for making a risk averse stay at something like +6 TC if surrender is not available but in general I am going to go with the expectation maximizing play (split) especially if I am taking a conservative approach where my max bet is less than .5% of my bankroll.

What are the index(es) for splitting and surrendering 88 v A in a S17 game?

Thx meistro

Do you mean the surrender index for 88 vs 10 is +1, and stay index is +6 ”could you double check if its +6 or +8”for no surrender game? But you prefer to split them even at high count max bet?

Well that is my point, it is kind of both. Typically your decisions in blackjack are determined by one metric, expected value. So a basic strategy chart, for example, shows which play yields the highest expected value for any given holding. So strictly from the perspective of expected value the play is as Wong describes, namely to split 88 v T if the true count is +7 or lower and to begin to stay at TC +8 or higher. But if you look right on the margin, at say TC 7.5, then you see that the expectation of splitting and staying are very close however splitting incurs significantly more variance. This is a big deal because a winning gambler is at war with variance. After all, if you have the edge, you will win in the long run but short term fluctuations (variance) can beat you. This phenomenon is so pronounced that one would be willing to accept a significant decrease in winrate if you were to simply win at a fixed rate as opposed to suffering the swings entailed with counting cards. We would rather have say $60 / hr guaranteed than a $100 / hr win rate in your typical count game if somehow we were to simply win at a rate rate of 60 cents / hand.

I would definitely stay on 88 v T at +8 and I would definitely split 88 v T @ +5. I think for TC 6 and TC 7 some strong cases can be made for either staying or splitting and I am generally apathetic between choosing to split or to stay.

very astute observation, imho. proper decisions are pretty well spelled out for blackjack, other forms of advantage play, not always so much, so survival with respect to variance, advantage and bankroll is a big deal. never did fully understand the underlying principles behind kelly betting and certainty equivalence, but i suspect your pronouncement above sums up a good bit about those concepts.
