I said I didn't like 16.f4. How convenient of you to pick the position after move 16 to rant about lol.
Anyway, I'm not interested in arguing. After 8.d4 maybe black is fine with best play, but I prefer white.
But most people don't go for such lines. They play 4...Bxf3
when i play the caro two knights (Via 1.nc3 move order) the only line that i have slight trouble against is 3...nf6. the bishop lines i never understood. Why give the bishop pair so quickly, for not much?
