Customer Reviews

One of great counting systems
I usually don't write reviews, but I decided to on this one, because there are some reviews that are idiotic. So, let me share with you my experience. Not only have I read this book, I have actually USED the system. Not only have I used this system, I have also used Hi-Low, and Hi-Low OptI. This book specifically tells you why he wrote it from the beginning, and mentioned all the ins and outs of the count. It is well written, and if you have IQ over 50, you'll understand it. Now the real story.

Basically unbalanced count was developed for the "real" world. Why, try Hi-Low OptI count for 8 hours at a packed casino. Try going there 8pm on friday night, and see if you'll find a table with 3 players only. LOL. You won't. Hi-Low OptI is very draining on your mental fatigue, I doubt even 20 year pros can keep doing it for that long. What they have to do is, do it for an hour and move on to another casino, or table after break. Same with Hi-Low, although easier, it is mentally taxing. I actually sat at a same table ($15) and played for 8 hours straight using KO. It's taxing, but not so much as balanced system. That's what it is designed for.

The book comes out telling you that it's not good as balanced count system, but by miniscule fraction! BJinsider did a great article (i think it's newsletter 29 - free) that showed how KO, Red7, BlackA did against Hi-Low on a 6-deck. Hi-Low was .68% gain, vs .67% for Red7, .65% for KO and .63% for BlackA. The great thing is you don't have to take his word for it. You can download some of these testing softwares or buy it, and run the test yourself, and you should get a similar results.

Now, the final point. All these statistics for counting are using A LARGE # of hands played, to minimize noise and get the actual true "worth" of the system. Remember, you have to play over million hands to actually see these results. .65% is little over 1% advantage over the house. You ain't going to make thousands consistently playing 500-600 hands a week. That why there was the mit "TEAM". They main objective is to get as many hands played possible (they also cheated little using team work, but we'll leave that for another day). If you can get 45-60 hands/hour, you can probably play 10-12 hours/day with break in between. that's like 600 hands avg a day. You have to play 7x600 = 4200 hands. 4200x50 = 210K hands. Do that for 5 years, and maybe you'll stiff 6 figure gain. You want a LIFE like that? (exaggerating little bit, but you get the point)

So, what I'm trying to say is KO is a GREAT system for casual players, as this book was written for. It's also a good system for pros, since it's similar to Hi-Low in returns. Don't expect to leave the casinos with a whad of cash, if you're lucky it can happen. I once made over $2k playing $15 table in 2.5 hours. So, it's possible with KO. But you gotta be lucky too. Because I've also been busted couple of times too ($400 max each session). It's over the long haul he's talking about. Oh, unbalanced system becomes more accurate as deeper you penetrate the deck, so don't go crazy early on. wait for 3-4 decks to be gone, so each deck you'll only have 2 or 3 chances to bet big. That's still good enough if you get lucky, since odds are with you. I played many shoes that I didn't even get to bet big, it's ok. This is the grind. Big spreads are best, but can get heat, so learn some stealth from this book or other books. Go there to have fun, make some money if you are lucky, just don't expect to be rich unless you plan on 12h x 7d x 50wks x50yrs BJ life. Hope this helps.

Edit: I forgot to add this tidbit, since I mostly play AC and they only have shoe games. But for 1 or 2 deck games, I'd recommend learning the Hi-Low as you want more accurate count then. But for shoes games KO and Red7 is just as nice.

Highly recommended
If you are an amateur, which you probably are if you are reading this, stop reading right now. Get out your credit card and order this book.

I ordered this book a little over a year ago, and since then I am 8-1-1 in my last 10 casino visits. I am UNDEFEATED (too many games to count) in local private games with low table limits, which are fairly common here in this college town. This was all after practicing card counting for 30 minutes per day for about a month.

This is the most effective simple system you can learn to use. Forget about hi/lo. Knock-Out is an unbalanced system, which means there is no need to keep a true count. This is extremely valuable in a casino environment when you have cocktail watresses grabbing you every 10 minutes and the guy beside you won't shut his trap. Order this book, get a deck of cards, print off the strategy tables and go to work.

Whoa, hold on a second.
This system will not work.

Let's assume your playing in a 6-deck game. This system has you start your running count at -20, with -4 or higher as the "key" (The point at which you bet high). Using the KO method, after all of the decks are counted through the count will be +4. Does anyone else see the flaw here? Let's say you have a count of -3. This system tells you to bet high (Even suggesting 10 betting units!). But think about it, if a deck completely counted through will end up at +4, then there's a better chance that you'll be drawing low cards, meaning the dealer actually has the advantage. Put simply, if you use this system YOU WILL BE BETTING HIGH WHEN THE DEALER HAS THE ADVANTAGE. If I'm wrong then correct me, please. But I believe this is a very faulty system. If you win anything using it, count it off as luck. Eventually it will ruin you.

This book explains other counting systems as being near impossible for the average person to learn; even explaining how difficult the Hi-Lo system is (Bull). The Hi-Lo system is still the easiest effective counting system (Explained well in Wong's "Professional Blackjack") with the Omega II being one of the most powerful (Beautifully explained in "Blackjack for Blood" by Bryce Carlson). I highly recommend either one of those two systems.

There is a note in this book about the notion of blackjack books being put out by casinos to sort of sabotage counters with false tips. I believe this may very possibly be one of those books. Avoid, avoid, avoid.
