65-year-old GM takes out a super grandmaster

I love a good underdog game. This is one of them. 65-year-old US GM takes on a super-grandmaster and wins! It wasn't much but in the endgame the rook was over-powered by the Bishop pair and passed queen-side pawns.
​Lessons:
1) stay confident when your opponent is much higher rated; white pieces help, too.
​2) push your passed pawns 
3) use your bishops together on open lines for maximum effect.
