How do you know?

I need to get data and definitions in order to say that program X is tactical
and program Y is positional.

Data can be achieved by doing the following steps:

1)take care to get a result that is 50% between X and Y.
If X is better than Y then you should give Y the better hardwrae.

2)analyze the games and count for every program how many games it won thanks to
tactics.

Use the following defintions for deciding if a game is decided thanks to
tactics:

A game is considered as a game when the winner won thanks to tactics if the
winner was the first side to get a significant fail high and only in the next
move or the move after it the opponent got a significant fail low.

Significant fail high is defined as a fail high of more than a pawn relative to
the evaluation in early iterations.

Significant fail low is defined as fail low of more than 0.5 pawns relative to
the evaluation in early iterations.

Early iteration can be every iteration that the computer needed at least 1% of
the total time that it calculated in order to complete it.

The position before getting the significant failed high should be evaluated by
both engines as not more than one pawn advantage for the winner.


3)The program that is relatively better in tactics is the program that wins more
games thanks to tactic by my definition.
