KO Preferred Strategy Matrix

On Reading the chart, (KO Preferred Strategy Matrix pp 85)in the book
KO I understand most of the changes from basic strategy e.g. BS calls
for doubling 9 vs dealers up card of 3,4,5, & 6. On the chart it shows an A
(pivot point) when the player has a 9 and the dealer has a
2, or a 7. I understand that the player will now double down 9 vs a 2 and a 7
when the count is at or greater than the pivot.

BS strategy calls for standing with 12 vs a 4,5,& 6. On the chart it
shows a C (IRC) when the player has a 12 vs a 4,5, & 6. Does this mean
when the count is below the IRC the player, plays according to BS and
stands? and when the count is at or above the IRC the player hits?

I usually ignore category C, as I play I play a 6 deck game,
however I will be travelling to LV and will be playing one and 2 deck
games, help is appreciated, thanks in advance.

What percentage of the bj21 posters spend as much time playing as
they do posting? You clowns would be better off dumping the KO system
for a real count and get yourselves into the casino making money.
Nothing lasts forever.

How many have started with KO and had this regret:

"It was so easy to start with but now I am stuck with it. All these IRC and pivot charts sure seem harder than simply learning to true count."

Actually I can play both Hi/Lo and KO and prefer KO as it takes less concentration. Keeping track of the IRC etc. is a lot simpler than estimating and dividing decks while some ploppy is asking me what to do with a soft hand, or pointing out that if the anchor had taken a hit the dealer wouldn't have received a natural. I can talk and enjoy myself more, if I pay a small price for that then so be it. I play about 8 to 10 hours a week and spend an hour or two a week(on average)on this board.

BS strategy calls for standing with 12 vs a 4,5,& 6. On the chart it shows a C (IRC) when the player has a 12 vs a 4,5, & 6. Does this mean when the count is below the IRC the player, plays according to BS and stands? and when the count is at or above the IRC the player hits?

You have it backwards; you would stand if the RC is >= C and hit if below. This is because the higher the count the more likely you will bust with a 12 if you take a hit. It is also more likely that the dealer will bust with 4, 5, and 6 on high counts.

is to stand on 12 vs 4, 5 & 6. You said Does this mean when the count is below the IRC the player, plays according to BS and stands? and when the count is at or above the IRC the player hits? No, just the opposite. When the count is at or above the IRC, stand. When the count is below the IRC, hit.
