Yeah, I agree with this. Just play 19. Qd2 Bxc5 20. Qe2 and black looks pretty
bad.

Shredder wants to defend there with 20. .. 0-0 21. Bxh7 Kh8 22. Rf1 Qxf2+ 23.
Rxf2 Rxf2 24. Qxf2+ Bxf2+ 25. Kxf2 Kh7 but black is just going to lose this
ending.

Regarding the subject - actually, Fruit is going back to an earlier paradigm
which may make sense again now that search depths are greater. With shallow
depths, you take a huge risk if you underestimate king safety.
