Austrian Attack in Pirc Defense with 5...c5

After the opening moves 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4 Bg7 5.Nf3 c5, the following line of analysis was shown by a grandmaster to a player at the Marshall Chess Club.

According to the player, the GM claims that it refutes the 5...c5 variation.

6.Bb5+ Bd7 7.e5 Ng4 8.e6 fxe6 9.Ng5 Bxb5 10.Nxb5 Qa5+ 11.c3 Qxb5 12.Nxe6 Qc4 13.Qxg4 cxd4 14.Nxg7+ Kf7 15.f5 Kxg7 16.Be3 Nc6 17.O-O-O.

The grandmaster's analysis ends here.  Now the player gives the possible continuation 17...Qxa2 18.Bxd4+ Nxd4 19.Qxd4+ Kg8 20.Rde1 when Black is in dire straits.

Instead Shredder prefers 17...b5 18.Bxd4+ Nxd4 19.Qxd4+ Qxd4 20.Rxd4 gxf5 21.Rd5 a6 22.Re1 Kf6 23.Rf1 Raf8 24.Rfxf5+ Kd6 25.g4 Rhg8 26.h3 Kd7 with approximate equality.
