Since this topic is on KO, I have a question. Assume a 6-deck shoe. That calls for an IRC of -20. There are four more low cards in each single deck than high cards according to KO so if the deck is balanced, with each deck played, the count should rise by 4. That is, after two decks are played, you can get in indication of the condition of the remaining cards to be played by multiplying the number of decks in the discard tray by 4 and adding that to the IRC (2 decks played, the IRC would change from -20 to -12). Now, let's say that after those two decks are played the actual running count is -10 instead of -12. You are dealt a hard 16 and the dealer is showing a Face.
Would it be wise to go ahead and stand on the 16? KO indicates NOT to stand until the count reaches -4 in that situation but the probabilities are so close on the hit/stand decision that any information you have, no matter how significant, could and should be used to influence you to make the play that gives you the advantage no matter how minute that advantage is.
How about "insurance" and "even money" decisions. If the count is 7 more than it should be at any point, should you take this "insurance" side bet?
