Unbalanced Zen II Card Counting System
The card counting system in blackjack, first proposed by expert and player George C in 1996 in his booklet The Unbalanced Zen 2 and gained immense popularity. Refers to unbalanced 2-level 1-parameter counting systems. Playing efficiency PE = 0.62. Betting efficiency BC = 0.97. Often shortened simply to UBZ2.
In general, about unbalanced systems

They are more accurately balanced in that the assessment of the advantage, as well as the size of the deck, (in contrast, "by eye" in balanced ones) in unbalanced ones, this makes an array of cards for you (much more accurately). In accordance with this, you have a more flexible betting strategy, and an assessment of the advantage (which is reflected in more competent bank management for the game). For example, according to Hi Lo, you do not change the bet at +1.5 (because you are not sure, for example, +1.5 now or +1.3).
If you play according to an unbalanced system, you feel much more confident in these assessments. Do you understand my point? For example, according to Hi Lo, your betting strategy will be 1,5,10,15,20, then playing on an unbalanced one you will get 1,5,7,10,12,15,17,20. This is due to a more accurate estimate of the edges of the real account, such as +1.5 +2.5 +3.5, etc. In this regard, the win rate will increase, and the dispersion will decrease. You can clearly see this in simulations. On good cuts, this is especially noticeable.



ravenmilkers If Black Cube is really just an operator, then who spent money on such a large-scale operation? It doesn't cost 5 kopecks.



BatBulo4ka 5 thousand a day - well, this is no longer a player, but some kind of investor. It is quite reasonable to limit it.



CertifiedNiggur And then they wonder why the players are paranoid... Even dealers can no longer be trusted.


ImBrainless Damn, how sick these casinos are with their blocks! I had a situation in the pin-up, just when a big win was shining - 8k. And what do you think? They blocked the under the pretext of "suspicious activity". Two months of correspondence, and only after threatening to write to the regulator, the money was returned. Now I check 100 times where I go. Thank you for the article, a relevant topic!
