EVANS GAMBIT - "Evergreen Game"
White's K5(e5) Pawn removes the newly doubled KBP on KB6(f6) and sets a combined triple attack against Black's K2(e7) knight (now pinned).
Black rejects castling, developing his King's Rook to KKt1(g8) to pin White's KtP and threaten an immediate mate after 19..QxKt (ie. 20..QxKtP++mate).
