Re: It makes absolutely no sense

100 hands of 1 unit each more like?? How much wood could a wood chuck chuck if a wood chuck could chuck wood? Or is it would?? I photocopied that page so we can all look at it tonight.

When is ground hog day anyway?

The point of the exercise

The point is that even with fabulous cards and a huge count, horrible things happen. If one does this exercise enough (and 100 hands is not enough) then you will find the dealer pulling 3 21's in a row with a 5 showing, or the dealer getting 10 BJ's for your 1. Just enough to make you realize that even with a huge + count, life can really suck. And with these cards, that's exactly what happens, either you get a great run of cards or the dealer does, there is not much middle ground. It gives an experiential idea why the variance is so large when the count gets high.

The point.

Re: The point of the exercise

That is why I posted "You were also rather lucky." in the original reply. You can have an amazing edge and still get killed as you well know. That is why I mentioned minimum boldness, and using it to grind your edge instead of throwing yourself at it like a fly into the spiders web.

Re: Boss!! De Page! De Page!

What you said:
In The World's Greatest Blackjack Book on page 201 it shows two different scenarios. One where you have a 2% advantage and one where you have a 2% disadvantage. You have a 49% chance of doubling your roll betting it all on one chance with the -2 and 51% with the +2. BUT, by playing with smaller amounts, you can increase your chances of doubling by making 100 even sized bets over 100 hands. You have a 98.2% chance of doubling after these 100 hands. On the contrary side, you will have a 1.8% chance of doubling your roll after 100 -2% hands.

That supposed to be 100 UNITS, not 100 hands. Obviously it is almost certain to take more than 100 hands to win or lose 100 bets.
