Let's get going with a very interesting position from a game between GMs Shirov - Svidler, Aerosvit Foros Tournament, Ukraine 2008. After 24... b5 we reached the following position (see diagram). Questions:
a) Please assess this position for both White and Black; decide who is better (5 points)
b) Propose a possible line (6-10 moves) to prove your decision (5 points)
Total available points for this puzzle is 10. The answers will be published next week together with puzzle #27.
Puzzle #25 solution:
While upgrading the page to interactive diagrams (2020-04-23) I could not find any answer saved for this puzzle. As a result I have decided to simply present the remainder of the game as given on pages 41 to 46 of the "Chess on the edge" book, volume 1. Please read the book for all annotations by the authors.
