Here's the game:

According to the CM9000 database, 11...Rxc6 is the first "new" move. At this
point, The King (CM9_R1) thinks that Fute is up about +0.6, which is certainly
not insurmountable, but does point at a potential problem in the book moves that
were selected.

From this point on I can find nothing obviously wrong with Zappa's play, and it
just looks like the Champion was spending most of its time trying to defend its
weakened King position (whereas Fute's King was safe the entire game).

This allowed Fute to simplify and reach a drawing position. After 26.Rg4, The
King scores the game as "drawish", and it remained so for the rest of the game.

One patzer's opinion....
