Domdaniel: The same game score is given in other sources, but something must be wrong. The final few moves generally make good sense -- White plays 59.Bc6 to avoid the sucker-punch skewer after 59.c8Q Rc1+ -- and Black actually has good drawing chances after 61.a4. Just not with 61...Rb2 which loses quickly after 62.c8Q.
Instead, some possible lines are 61...Ra1+ 62.Kb3 Bxc7 63.Rxd7 Kd6 64.Rc8 Rc1 and 61...Bxc7 62.Rxc7 Kd6 63.Rc8 Rf1. A black ...Rf1 seems a better way of hitting the f2 pawn than ...Rb2, as the latter can be met with f4.
I suspect the last move in the given score, ...Rb2, is just random noise, and it's unlikely that it was played even after inserting ...Bxc7 and Rxc7, with or without ...Kd6 and Rc8.
Or maybe there was a gigantic time scramble and a draw by mutual terror of losing on time. Even so, you'd expect Black's 61st to be something that didn't allow the pawn to promote, like ...Bxc7 or ...Ra1+.
The *opening* is actually very interesting. Akobian has used this system with ...e6 and ...c6, followed by ...d5, ...dxe4, ...e5, on a few occasions as a weapon against the King's Indian Attack. It's most effective in the Chigorin line, 1.e4 e6 2.Qe2, where the White Queen ends up misplaced.
