*this may be apt in the openings forum, but I like this forum more

In the chess.com opening database there is one particular gambit that has created quite a bit of buzz around here, even though there are no master games listed in the database. The opening is the Four Knights Game: Halloween Gambit (or the Goblin; I've seen it listed as the Chicago Irish Gambit in one database, but Halloween Gambit is my favorite name for it). It is as follows:

1. e4 .. e5 2. Nf3 .. Nc6 3. Nc3 .. Nf6 4. Nf3xe5 ?? (!)

My questions are: why aren't there any games in the database? Why haven't any Grandmasters tested this for the chess public? If white can all but zugzwang black in just 6 moves, shouldn't the Knight be worth it? Finally, will a Grandmaster ever try this?

Thanks

This reminds me of a game played in a simultaneous exhibition given by Harry Nelson Pillsbury on 27 boards of Chess and 10 of Checkers in Chicago,IL 1/7/1899.

One D.T.Phillips played the White pieces and dared to essay the "Razzle Dazzle" gambit against H.N.P.

The game started with  1.e4,e5 2.Nf3,Nc6 3.Nxe5,Nxe5 4.d4,Nc6 5.d5,Nb8 and Phillips went on to win in 45 moves.

Haloween gambit is only strong if black is too greedy to accept the gambit. He soon find himself against tremendous pressure from whites attack.

By simply declining the gambit Black is already assured of equality without the vaunted complications.  No wonder we dont see the Halloween gambit in high level chess because White players doesnt want to give Black that easy equality.
