Tennison Gambit (1.e4 d5 2.Nf3)
One knight, a stolen pawn, and a web of early traps — the Tennison Gambit bets that an unprepared opponent panics before the engine's verdict catches up. Try walking the tightrope yourself in the drill below.

After 1.e4 d5 2.Nf3, Stockfish at depth 16 rates the position −0.87 — nearly a full pawn in Black's favour. That's a steep price. Unlike some dubious gambits that at least score well practically, the Tennison doesn't even deliver that: across 11.7 million Lichess games White scores 47.7% vs Black's 48.7%. The engine refutes it and the scoreboard sides with Black. It survives entirely on trap value.
Where the trap victims come from
The Tennison's entire practical value lives in a single trick: after 2...dxe4 3.Ng5, White threatens Nxf7 and Bc4, creating genuine tactical chaos if Black grabs pawns greedily. Three popular-but-wrong responses show this clearly:
- 2...d4 — mistake, 171 cp loss vs the correct dxe4; White suddenly gets a comfortable centre
- 2...Nf6 — mistake, 159 cp loss; stepping into 3.Ng5 pressure immediately
- 2...e6 — inaccuracy, 98 cp loss
Avoid those and the gambit collapses.
The correct defence: take and develop
Stockfish's answer is 2...dxe4, accepting the pawn. After 3.Ng5 Black simply plays 3...e5 — defending the pawn while pushing back — and White's piece activity is insufficient compensation for the material. White scores only 47.1% when Black plays 2...dxe4, the most popular response across 10 million games.
Why people keep playing it anyway
The Tennison is a pure surprise weapon. Against anyone unfamiliar with 3...e5, the tactical threats after Ng5 feel overwhelming over the board. It's a legitimate blitz or bullet trap at the cost of being objectively busted at every time control. Go in knowing that: it's a chess trick, not an opening.

Frequently asked questions
Is the Tennison Gambit good?
Objectively, no. Stockfish evaluates the position at −0.87 (Black better), and even practically White scores only 47.7% vs Black's 48.7% across 11.7 million Lichess games. It's a pure trap weapon.
What is the best response to the Tennison Gambit?
Accept with 2...dxe4, then meet 3.Ng5 with 3...e5. White scores just 47.1% when Black takes the pawn — the gambit falls apart against correct play. Declining with 2...Nf6 is a 159 cp mistake.
Why does the Tennison Gambit work in online games?
Because the traps are hard to see quickly. After 2...dxe4 3.Ng5, White threatens Nxf7 with check and Bc4 simultaneously. Many players blunder in time trouble or just don't know 3...e5. Once the opponent knows that move, the gambit fizzles.
Is the Tennison Gambit the same as a Nakhmanson Gambit?
No. The Tennison arises from 1.e4 d5 2.Nf3 and is a piece sacrifice to disrupt Black's centre early. The Nakhmanson is a completely different Italian/Centre Game system. The move orders and ideas are unrelated.
