I can see some fifty games played like that- a few of them between GM's.
The problem with it is 7...Nc6 against which white has tried all three sensible moves (8.Bc4, 8.Bb5 and 8.0-0-0) but Black seems being just better in all cases (although it's rather easy to blunder if you first meet this position OTB).
My Kings Gambit Novelty.
Can you see a refute? I want to know out of curiosity and for use in real games.
