Interesting. How long did it take?

Would learning for white increase draws significantly?

I confess that I didn't try too hard to move forward quickly in this project because Eman had other openings to learn.

Since I want to get a (perfectly) balanced experience file (distribution of trained openings), from "1.g4" it produced too much "ECO A" openings...

But otherwise the games were mainly played at TC 1m+1s @ 7-8 threads so depending on how many openings were trained at the same time, it can go quickly :

I doubt !
As you know, the "key" positions with a "high draw rate for white" are very rare after "1.g4".
Each time I found one of them, i trained Eman and after 2000 games the "draw rate for white" had always dropped.
Even with an odd tc like 1m+1s vs 5m+5s, "Eman 1m+1s" managed to win some games after "1.g4".

A lot of work.
