[lang_nl]Hard-core Zaitsev-theorie in Czech Open[/lang_nl][lang_en]Hard-core Zaitsev Theory in Czech Open[/lang_en]

[lang_nl]Het Czech Open in Pardubice is een van de grootste, zo niet h?ɬ©t grootste schaakfestival ter wereld, met iets meer dan 1700 spelers dit jaar. En niet alleen een schaakfestival, want er zijn ook toernooien in backgammon, kruiswoordpuzzels, dammen, sudoku, poker, bridge en zelfs Rubiks kubus! Later kom ik uitgebreider terug op het festival maar vandaag ga ik het hebben over iets wat we al een tijdje niet meer gezien hebben hier op ChessVibes: hard-core openingstheorie! Normaal gesproken kom je lange theoretische varianten vooral tegen in de gesloten groepen van het eliteschaak en niet in dergelijke grote open toernooien, behalve... als supertheoreticus Vasilios Kotronias meedoet. Gisteren, in de vijfde ronde, trok een fantastische Zaitsev-Spanjaard de aandacht.[/lang_nl][lang_en]The Czech Open in Pardubice is one of the biggest, if not the biggest chess festival in the world, with a bit over 1700 players this year. And not even just a chess festival, since also tournaments in backgammon, crossword puzzles, draughts, sudoku, poker, bridge and even Rubik's cube are held! Later I will write more about the festival, but today I will focus on a subject that hasn't been treated for a while here on ChessVibes. Hard core opening theory! Normally long theoretical lines are seen in the elite round-robins and not in these huge open tournaments, except... when super-theoretician Vasilios Kotronias is playing. Yesterday, in the fifth round, an amazing Zaitsev Ruy Lopez attracted the attention.[/lang_en]

In your reference to the excellent book by Sverre Johnsen and GM Leif Johannessen, you got a little typo, it is supposed to be 2. Nc6 instead of 2. Nf6 (Ironically Kotronias is also an expert in that opening)

Once again a great article Peter.

I also advice the readers to play through the game Kotronias-Bologan which is one of the most entertaing games I had seen in a while

Mind-blowing stuff. But isn't the Black player Philip Schlosser?

Rybka indicates that 32.Kh2! avoiding the Ra1 pin is stronger. Perhaps white can try for an advantage that way. F.e. 32.Kh2! Nd3 33.f4!

In any case, the 26.Nh2? from Kotronias - Bologan is totally lost for white.
