The Tennison gives up e4 to turn a quiet knight move into immediate pressure on f7. Learn when Bc4 builds a sound initiative, when d3 launches the ICBM pattern, and how an early queen grab can become a target. Playing the positions matters because the gambit's surprise value disappears the moment you stop calculating the forced replies.
Study four White attacking routes and four Black defensive lessons. The set covers Bc4 pressure, the ICBM queen capture, the ...Bf5 king hunt, the greedy-queen trap, the active ...e5 antidote, and the Greek Gift warning. Per-move editorial notes remain for the later Opus pass.

Source trail: every SAN path and training board comes from the Tennison Gambit guide and its position bank. The five retained test answers are Be4 (+2.96), Qh5+ (+0.49), Bxh7+ (+1.86), Nxf7 (+1.56), and Qxd8 (+3.03).
The 16 boards test f7 pressure, pawn recovery, queen pursuit, the ICBM sacrifices, Black's ...e5 antidote, the ...Bf5 pawn hold, and the Greek Gift. Every candidate move is legal on its exact board, and every explanation stays attached to an observable piece or pawn consequence.

Choose any of six verified starts and set the bot from 600 to 2500. Eleven coach triggers recognize the accepted pawn, both main defenses, the f4 overreach, the ICBM launch and refutation, the greedy queen, the f3 offer, and the Greek Gift position.
The six starts include the exact 1.e4 d5 2.Nf3 dxe4 3.Ng5 base, all four recorded book seeds, and a no-book Greek Gift position. Each color receives the logical opposite on the same named pieces and squares.
