Got South Poled in this Ending

Played a guy at ICC name Reb from Antarctica. Wonder if Reb is short for rebel which you would have to be to live in an area larger than the United States covered by mile thick layers of ice! Reb moves deliberately and seems to prefer endings. He frequently reaches won end games, but loses on time before he can convert the win. Such is the burden of playing 3 minute blitz chess.

The position you see below is likely a win for Black with with his strong Knight and White's passed pawn has no chance of promoting. Also White's g1 Bishop is a prison bitch to the powerfully centralized, fire-breathing Steed!

I wonder if Reb is a scientist as there are no indigenous Antarcticans, but scientists from around the world are allowed to capture data and do research on the southern tip of the Planet Earth. Also, there was some sort of world wide agreement preventing the use of this frozen continent for military purposes or nuclear activities.
