2015 CEZ Trophy won by Wesley So

by Albert Silver
6/17/2015 – Every year, the Prague Chess Society and CEZ have organized a match for their top Czech player, David Navara, often against opponents that outrank even him. Last year he lost to Nakamura in a lopsided match but the American is also world Top 3-4, no exactly lightweight. This year it was Wesley So, also challenging the establishment, and was a remarkable victory for the American.

The match was met with interest and had a steady flow of spectators and media covering
it. Aside from guest lecturer Mark Dvoretksy, the live commentator GM Robert Cvek also gave
lectures to the audience. This one is on transitioning a middlegame into a favorable endgame.

Prior to the match, top Czech player David Navara had released his newest chess book (in
Czech). Here he is signing copies.
