Yes Fernando, you are sooooo right! :))

I love this thing too. I think CST is a truly different and brilliant
program. It has an impressive ability to push the opponent against the
corner and to play unexpected attacking moves. It is fun, it plays
chess, it's intelligent, so what else do you want.

But... (there is always a "but", oh well...)on the other hand, it is a
bit tragic to see it lose won positions because fast searchers outplay
it in tactical complications. I guess this doesn't matter so much when
playing humans, but this is the pattern I saw when CST played Fritz 5
and Nimzo 98. The 2 games I post are an example of positions that CST
should have never lost. Maybe after reaching such a strong advantage it
should switch to more "computer-like" play in order to materialize the
advantage.
