COLOUR AND INVERSE
Contrary
of what happens considering Red and Black, chances of
Colour and Inverse can suffer some percentage variations
depending on pack position. We can run into these differences
only in packs having few cards (max. 20-30). In any
case chances have got absolutely the same probability.
We're
going to analyse an "extreme" example of a
pack in which the advantage of one of two chances is
clear.
In
the pack we have seven 10 and only 3. The 3can move
in 8 different positions, having the same probability.
Let's analyse the following position considering scores
and results of each blow.

Now we have to analyse what happens in EVERY SINGLE
CASE:.
1st case: C winning
2nd case: I winning
3rd case: I winning
4th case: I winning
5th case: C winning
6th case: C winning
7th case: C winning
8th case: C winning
Considering
8 cases, 5 have got colour winning, only 3 the Inverse
winning. We're talking aboiut a mathematical advantage
of 25%. You can try, if you want to invert colours.
Obviously there are other cases in which we can have
some advantages and ohter cases in which we can obatin
godd advantages even if not so elevated.
Unfortunately these cases are
rare and have benn erased by the practice of not considering
the 5 starting cards... In any case, as in
this one (burned cards), some remaining composition
can bring some mathematical advantage. Example:
A Black Ace
A Black 2
A Black 3
A Black 4
Three Red
8
Three Red 9
Eight Red 10
Total remaining: 18 cards
% Winning Colour: 51%
% Winniing Inverse: 39%
% Equal 31: 2%
% Other Equals: 8%
And all this happens even if we burn 5 cards!!
The problem is that game's chances are not so big, and
advantages are really slender.
These makes every speculation's hypothesis totally hard
to do.
