History

The first person to significantly research this opening was chess amateur Otto Mandrup Tennison (1834–1909).78 Tennison was born in Denmark, studied in Germany and moved to the United States in 1854.1 There, he played in the chess clubs of New Orleans. Many strong players picked up the idea from the first half of the 20th century.

Analysis

The Tennison Gambit is considered theoretically unsound, as White sacrifices a pawn immediately with no solid positional compensation. Without precise counterplay, however, Black can easily fall into a number of tactical traps that leave White ahead.9

After 2...dxe4 3.Ng5:

  • 3...Nf6 4.Bc4 e6 5.Nc3 a6 6.Ngxe4 Nxe4 7.Nxe4 b5 8.Be2 Bb7 9.Bf3 and White had the advantage in Ermenkov–Bonchev, Bulgaria 1970.
  • 3...e5! 4.Nxe4 f5 and 4.h4 Be7 5.Bc4 Bxg5 6.Qh5 g6 7.Qxg5 f6 favor Black.10
  • 3...Bf5 and Black has the better position. A continuation might be 4.g4 Bg6 5.Bg2 h5 and Black keeps the advantage in a sharp position.
