Most players know of Froms’ Gambit [1.f4 e5 2.fxe5 d6 3.exd6 Bxd6 4.Nf3), with continuation of either 4…g5 (to drive away the knight) or 4…Nf6 (to defend and ready to redeploy the knight to g4 or e4)].
But White can also offer a similar gambit after 1.f4 f5 2.e4 fxe4 3.d3. This gambit is known as the Swiss Gambit. Because of its rarity, most players are not aware of it or it’s thematic ideas.
Let’s take a look the gambit after the opening moves (1.f4 f5 2.e4 fxe4 3.d3).
If Black was to take the pawn, he would be a pawn up in the game. However, it would be hazardous to do so as both of White’s bishops (after 3…exd3 4.Bxd3) would be activated and his own kingside would be vulnerable. There are two things that slow down White’s attack. The first is the f-pawn, which unlike in the From’s Gambit (which does not have such an advanced pawn), blocks the bishop from going to f4 or g5. The second thing is that Black usually plays an early 4…Nf6, to stop the h5 checks.
Now, lets look at some games.
First, Black does not have to take the pawn. But such a plan can be risky as the d3-pawn can easily capture the e4-pawn and White has a nice center, without having to sacrifice a pawn.

If Black wants to decline the pawn offer, he must play an early …d5.

After the moves 1.f4 f5 2.e4 fxe4 3.d3 exd3 4.Bxd3 Nf6 5.Nf3 e6, White has three excellent choices of 6.Ng5 (A brazen attempt at an attack, probably best for a blitz game), 6.Ne5 (a more cautious and shy approach to an attack), and 6.Be3 (a developing move that allows White to castle queenside if the need arises).
1.f4 f5 2.e4 fxe4 3.d3 exd3 4.Bxd3 Nf6 5.Nf3 (a very good move as the knight usually finds itself involved in White’s attack.) 5…e6 (this move is the most common as it allows his bishop to develop and bolsters his defense of his weak point on f7.) 6.Ng5!? g6 (not 6…Bc5? because of 7.Bxh7 Kf8 8.Nxe6+, winning) 7.h4 Bh6 8.h5 Bxg5 9.fxg5 Nd5 10.hxg6 Qe7 11.Rxh7 Rxh7 12.gxh7 Qb4+ 13.Kf1 Qh4 14.Bg6+ Ke7 15.Qh5 1-0
