Chessmaster 9000, on a P3-733, finds Rg6 in less than one second, and gives it a
drawish score after 11 seconds. The final drawing PV includes all moves up to
and including 33.Nxg7....

After forcing all of those moves, it takes eight seconds and depth 10 to see
33...Nf2 as winning, so you can draw your own conclusions about how soon The
King would see the win at tournament time controls:
