BountyHunter BDG Huebsch 4.Nf3

In the Blackmar-Diemer Huebsch Gambit after 1,d4 Nf6 2.Nc3 d5 3.e4 Nxe4, White almost always captures the knight with 4.Nxe4. I noticed a curiosity years ago. When very high rated computers played this line as White, they often did not take on e4. Instead these chess engines developed a piece such as 4.Nf3, 4.Bd3 or 4.Bb5+!?

“BountyHunter” was usually some version of Rybka. Here it won a Blackmar-Diemer Huebsch Gambit against the very high rated unknown opponent with the handle “uncles”.

The moves 4.Nf3 Nxc3 5.bxc3 give White a few little advantages in exchange for the disadvantage of being a pawn down.
What are White’s advantages?
1. A strong pawn on d4.
2. A better control of e5.
3. A lead in development.
4. A rating over 3000!

This line is section 5.1 in my Blackmar-Diemer Games 2 book.
