The Tennison Gambit is a variant of the Scandinavian Defense in the opening of the chess game . Since a player (white) sacrifices a pawn, it is a gambit . It is one of the seldom played opening variants and is also called the Lemberg Gambit or Abonyi Gambit. The Tennison Gambit is very similar to the Budapest Gambit (colors swapped).

history

This opening was played for the first time by the chess amateur Otto Tennison (1834–1909). Tennison was born in Denmark , studied in Germany and moved to the USA in 1854 . There he played in the New Orleans chess club , he is not known to have had any extraordinary chess successes. Many strong players took up his idea from the first half of the 20th century and made this gambit socially acceptable.

variants

The rejection of the gambit is possible with 2.… c7 – c6 or 2.… e7 – e6. Both lead to an even game.

Accepted gambit: 2.… d5xe4 with an attack on the f3 knight. 3. Nf3 – g5 with a counterattack on the black pawn on e4. You can now play 3.… e7 – e5, 3.… Nb8 – c6, 3. Bc8 – f5 or 3.… Ng8 – f6.

• 3.… e7 – e5! returns the pawn and is considered the strongest move. Numerous plans are possible. Black often wins several tempos by attacking the white knight. 4. Ng5xe4 f7-f5. Black now has a pawn duo on e5 and f5, which means a small advantage. But the diagonal e8 – h5 is weakened. Qd1 – h5 + can take advantage of this.
  • 5. Ne4-g3. Save the knight. But the position is advantageous for Black.
  • 5. d2 – d4! Offers the knight as a sacrifice . Black is better here too.
    • 5.… f5xe4 ?! 6. Qd1 – h5 +! with a balanced position.
    • 5.… e5xd4! 6. Ne4-g5
• 3.… Ng8 – f6. This natural move is the most commonly played move. He defends the e4 pawn, develops a piece and prepares castling, but allows White to set a trap with 4. Nb1 – c3.
  • 4. Bf1 – c4 is the best move with only a small advantage for Black. Bc4 and Ng5 now attack the weak pawn on f7. Black should therefore play 4.… e7 – e6 to block the diagonal of the bishop, which also blocks the white-squared bishop on c8.
  • 4. Nb1 – c3 attacks the e4 pawn again.
    • 4.… Bc8 – g4 with a counterattack on the white queen. 5. Bf1 – e2.
    • 4.… Bc8 – f5 defends the e4 pawn. 5. Qd1 – e2 attacks the e4 pawn again. With 5.… Qd8 – d4? only one move left to defend the pawn. 5. d2 – d3 and 5. Bf1 – c4 are better. Correct for Black after 5. Qd1 – e2 is to be returned to the pawns, for example with 5.… a7 – a6, 5.… Nb8 – c6 or 5.… Qd8 – d7.
      • If Black defends the pawn with 5.… Qd8 – d4? if he loses at least one piece: 6. Qe2 – b5 +! with a check bid and a double attack on the bishop f5 and the pawn b7. 6.… Bf5 – d7 7. Qb5xb7 Bd7 – c6 with an attack on the queen b7, which indirectly defends the rook on a8.
        • 8. Bf1 – b5 ties the c6 bishop to the king, with a winning position.
        • 8. Qb7 – c8 + Qd4 – d8 9. Qc8xd8 + Ke8xd8 10. Ng5xf7 + attacks the king and rook.
