Avoiding question marks, or any other form of punctuation to evaluate this opening, suffice it to say that the only games of grandmasters on record, of which there are four, were played by notorious opening mavericks: Morozevich, Miles, Hodgson, and Hillarp Persson.
4.Be2
d6
Both Morozevich and Miles preferred to fianchetto their knight with 4...Ng7 here.
5.Nf3
Nc6
Other than the oddly placed knight on h5, the structure and pieces are identical to an Alekhine defense.

Black is still struggling to find a good plan and while his bishop looks strong on e5, it won't be able to stay there for long, while the knight on g7 is still seeking a suitable home.
