I guess that the same is also for Junior.
I started to see sacrifices in Junior's game even before GambitTiger became
commercial.

I am talking about the version that played in WCCC and not about the commercial
version.

In WCCC it was an experimental version that probably was not better than the
commercial version(it made in this tournament also mistakes that the commercial
version did not do).
I remember that it continued to do also wrong sacrifices in games against humans
in club kasparov.

I guess that Amir had to test it a lot before the change became to be
productive.
