For example using more time in move 51 when you remember that you had a fail low
at move 52

I am interested to know what are the practical results of the following way of
learning:

1)playing many the moves that you played in a previous games in 0 seconds
2)starting to calculate and using more time one move before the move that you
remember a negative evaluation of more than 0.5 pawn against yourself.

What is the probability that a program that lose is going to lose again in these
conditions?

Note that one of the possibilities may be that the opponent may have no time to
use on your time so the opponent may play a different move earlier.
