You're really going deep here with the opening.
I used to play this line with both colors. 16. Rg1 was the big bomb in this
line, that practically killed it. 16. .. h5 is a better defense, but black
already has some trouble. 13. .. Bxg5+ is better - but here too it's not so easy
for black.
The reason nobody good plays 6. Bg5 any more is 7. .. Qb6. Leko was trying this
with 8. Nb3 for a while, but not he's dropped it too. Fischer's intuition was
right.
