增四度 (Augmented fourth)

David Navara – 丁立人 (Dīng Lìrén)
5th Gashimov Memorial; Şəmkir, April 26, 2018
8/2r2pk1/1q1p2pb/1pnPp2p/2p1P2P/2P3P1/RPB2PK1/4QN2 b - - 10 33

Position after 33. Kf3-g2

David Navara’s Anti-Marshall went wrong from the beginning, starting with his 12th move, which was soon followed by the exchange of White’s dark-squared Bishop for a Knight, thus allowing Black to mount a King’s Indian-like position on the Kingside. Seeking out new horizons, Navara soon ended up ceding ground on the Queenside too. Finally, a sequence of erratic moves precipitated White into the bleak position shown in the diagram. Black to move and win. 33. ... b4! 34. cxb4 Nd3! 35. Bxd3 cxd3 36. Ra1 Rc2 (Δ ... Rc2-e2) 0 : 1.
