Incredible engine line in the Nf3-Bf4 variation of Modern Benoni


The first line is like watching some Fabiano v. Magnus world-championship prep voodoo ...
I've noodled around with the Modern Benoni on a few occasions, but never really analyzed it. Though I have discovered that the c5-c4 pawn push is often useful, just to get some more maneuvering space and activity for Black - even if it means tossing the pawn away for free.
