Exceedingly Tough Rook and Pawn Ending

Can you find the only winning move for white?

This is a tough ending, bordering on inhuman. It is derived from a longer study that Gonzalez created, but this position is likely the one from which he constructed the composition working backwards. There are a few natural looking moves that only draw with best play- you really should start there and understand how black draws afterwards- then try to find the winning move for white.

However, 1.Re1 is the right start.

Same note I gave to Dave who never replied- 1. ....Kd5 is a tougher defense to overcome.
