Hi Uri,

You should run the match with many more games, 20 games is not nearly
enough to claim Junior is better at this time control, it's only an
indication of this.  Especially with a score of 12 to 8.  I have seen
results much better than this with even more games turn completely
around.  If 2 games had been won by Fritz the match would have been
tied.  I'll bet a lot of games could have gone either way.  To see
what I mean, flip a coin 20 times and note the scores.  Do this a
few times and note how often the results are exactly 10 tails and
10 heads, not very often.  Most of the time you will see a few
extra heads or a few extra tails.  The single most likely result
will be 10-10 but this will still be a fraction of the time.
