Maybe fritz was transposing into this GM encounter?

Benjamin,J (2620) - Fedorowicz,J (2545) [A45]

USA-ch USA (6), 1993

1.d4 Nf6 2.f3 e6 3.e4 d5 4.Nc3 Bb4 5.e5 Nfd7 6.f4 c5 7.a3 Bxc3+ 8.bxc3 Qa5 9.Bd2 Qa4 10.Nf3 b6 11.Bd3 Ba6 12.0-0 ½-½

Anyway, it's of course reminiscent of the Fantasy variation in the CK or 1.e4 d6 2.d4 Sf6 3.f3 d5 4.Nc3 e6 when it's White's turn!

e.g.

Miroshnichenko,E (2510) - Firman,N (2505) [B07]

But even if 4.f3 vs the FR is hardly the best version of this set-up, it does seem to have some potential as a surprise weapon!
