an aggressive response for black!

Getting in to fianchettos on b7...... and also very similar to the benko gambit!!

also the same positions can arise like this.

The difference between this and the benko gambit, I am no expert, but this is what it looks like, is that in the benko gambit, the pawn can be taken instantly.

However in the blumenfeld the white d-pawn must take the black e-poawn firt, this gives black a chance to get large ocental control afterr the below continuation.

yes what if cxb?

haha duh just winning it back with Qa5+ with an advantge for black play can go something such as this.....

here's an interesting game with the blumenfeld
