taking with the knight white still has an advantage but its a wet, explosive game. one mistake and youre dead.
the reason it isnt seen much is due to the bishop take. win a pawn, hide, and survive in a more dry game.
usually after winning a pawn "surviving" is literally that- dunking tons of punches. in this variation though its not that at all, black can never get enough pieces out to do damage. check the few games in the shredder GM openings DB where the GM takes with the bishop and retreats to b3.
