In recent opening texts this has even been nicknamed the Hara-Kiri Gambit!} (5. fxe4 {is the main alternative when Black most often prefers to recapture with the knight} Nxe4 ({although Gary Lane makes a case for the paradoxical move} 5...

Nc6 {with a very comfortable game.}) 8. Ne2 {This does not appear White's best line. Opening texts detail instead} (8. c4) ({and} 8. h4) 8... Nd7 { Solid but the more active} (8...

It was (and still is) in a excercise book of press cuttings made up when I first started playing chess and was from one of B.H.Wood's columns (possibly the Illustrated London News). It exerted something of a slight fascination and shows that even after what seemed like some clever chess a game can turn around in a jiffy when this is met by even smarted chess. Many such turnarounds have been observed, especially in otb club chess as well as rapid on-line chess, since that time.}) 1-0
