I expect you to see cases when Genius evaluates positions wrong if you do more
games.

I saw cases when Genius did not evaluate correctly king attack.
It falled into a king attack against chess system tal many years ago because of
wrong evaluation and I expect it also to fall into king attacks against
gambittiger.

It did not happen in the 3 games that you posted but it does not say that it is
not going to happen.

There are cases when Genius3's evaluation is superior relative to Gambit but I
believe that there are also cases when it is the opposite.
