FM Jorge Peleaz really played a model game with the White pieces. Once the hanging pawns are forced into the unfavorable c4-d5 formation, the bishop on e6 is much less powerful than the dancing knight. 46.f5! is real purty.
If Black can find a way to get away with this line, the 6...g6 idea is golden. Until then, there's always 6...Be7.
