Grishook's D5 Line

I wasn't sure after G3 if you played Bishop to V4, if you played D5 or 94, all are decent moves. But I kind of expected him to play the D5 line with Bishop C5 because it's considered this is actually Grishook's invention. And then at some point they realized that Black can play as we've aged six and basically everyone stopped playing this whole thing. White has absolutely nothing. No ideas. It's still like obviously a tense position. But from a theoretical point of view, nobody wants to enter this White.
