Upset wins by Bazakutsa and SivanandanUkrainian IM Svyatoslav Bazakutsa moved into sole first place at the British Chess Championship after defeating nine-time champion Michael Adams in Tuesday's fourth round. In this Fritztrainer, Grandmaster Ivan Sokolov - continuing his successful series "Understanding Middlegame Structures" - takes you deep inside the complexities of the Colour-Reversed Benoni, the Colour-Reversed Benko Gambit, and the Colour-Reversed Blumenfeld Gambit. Sivanandan joined the chasing group with an upset victory as black against fifth seed Ameet Ghasi. The game reached a symmetrical position in the early middlegame, but a couple of timid moves by Ghasi allowed Sivanandan to seize the initiative. With 3.Nf3 gaining popularity as a way to avoid Nimzo-Indian setups and the challenges Black faces in the Queen’s Indian, the Ragozin offers a solid and dynamic alternative.Free video sample: Introduction Free video sample: 5.cxd5 exd5 6.Bf4...109 playersAll available gamesLinks
