The Elephant Gambit. This leads to a nice open position at the cost of a pawn.

Nxe5 is also possible here.

This protects the e pawn which was still threatened, clears one piece out of the way of castling and takes a sneaky aim towards h2 for when the e pawn moves.

This supports an advance of the e pawn and contemplates the possibility of opening the f file in due course.

Unpinning the Queen which now supports an e pawn push and can also be transferred to f7, g6 or h5.

A thematic push that weakens the dark squares near white's king.

Benefiting from the pin on the f3 Knight.

Planning Nc5 then on to e4...

Freeing the a8 rook and discouraging Nb5 which concerned me in some lines.

A prelude to Ng5 perhaps...
