Very Simple, Yet Powerful, UBZ System for DD

From Stanford Wong's BJ21

I've been playing around with the Unbalanced Zen at Double Deck, and have come up with what I think is a VERY simple system that none-the-less yields a near 2 unit per 100 hand Win Rate(1.91) in a heads-up 70 card H17 DAS 1-6 spread game, with no true count, just a very few (8) departure indices (NO splitting of 10's, of course) and bets based on 5 easy to remember 'rules'.

Here is the 'system':

Use UBZ card tags. IRC of -8.

Rule #1:

Relax and play DD H17 BS, flat betting 1 unit anytime the Running Count is < 0.

At RC = 0

Rule #2:

Anytime the RC = 0, Bet 2 units and start to make this departure: stand on 16 v 10

Up until 1 full deck is in the discard tray:

Rule #3:

At RC = +2, bet 4 units and add these 4 departures:
Take Insurance. Stand on 12v2 and 12v3 Double 8v6.

Rule #4:

At RC = +6, bet 6 units and add these 3 departures:
Stand on 15v10 Double 9v7 and 8v5.

Rule #5:

After whole 1 deck is gone, perform Rules #3 & #4 at exactly 1/2 the Running Count you used during the first deck, i.e. do them at RC = +1 and RC = +3, instead of +2 and +6, respectively.

And that's it.

ROR on a 400u bank is 15.7%.
500u are needed for 10%. ROR.
650u are needed for 5% ROR

N0 is 22,642 (hands to achieve +1SD result)
DI is 6.7.

I sim'ed a Hi-Lo player under the same conditions, except that the Hi-Lo player used all of the I18, including splitting 10's. Hi-Lo bet 2 at +2tc, 4 at +3tc, and 6 at +4tc.

Both sims were 500,000,000 rounds.

My simple UBZ system edged out the Hi-Lo player, who won at a 1.89u/100 rate, 16.7% ROR on 400u, 515u for 10% ROR, 670u for 5% ROR, N0 of 23,657, and DI of 6.5.
