Against 5.f3 Pinski recommends 5...e6 6. e4 exd4 7. e5 Qe7 8. Qe2 Ng8 9. Nc3 Bb7 10. Nh3 c4, and is fairly dismissive of White's chances.
Parenthetically, for a while I thought that an interesting piece sac, not considered by Pinski, might be good: 11. Nf4 Qc5 12. Nfxd5!? Bxd5 13. Be3 Qb4 14. a3 Qa5 15. Bd2 Be6 16. Nd5 Qd8 17. Qe4, but I eventually decided that Black is O.K. here.
I've been analysing this piece sac, and it seems quite promising for White (if he plays
17.Qxc4!). However, I've just discovered that Nakamura has already beaten me to it:

There's some analysis of the game here:

Well I'll tell you what, Paul, if 6...exd5 is out of business, then 5.f3 is in business and not only that, but I'm a 5.f3 player again. Which suits me fine since 5.f3 has always smelled like a refutation to me.
Say, off topic, I saw a nice anti-QGA game of yours with 3.e4 e5 and subsequently White's b4 against the c5 bishop, in my data base. Pretty good chess, that.
