EVANS GAMBIT - "Evergreen Game"
White developed his QR to Q1(d1), the turning point in the game (the "natural move" being 19.B-K4) - he aimed to take advantage of the open K-file (e-file).
Black's KR4(h5) Queen captures White's knight on KB6(f3), for 20..QxKtP++mate, and White must now give check with every move to avoid defeat.
