Match Play Red trails 0-1 to 5. Should Red redouble to 4? If redoubled, should White take?

This position is a classic demonstration of the power of the match score.

For money redoubling here would be a triple blunder. At this score, by redoubling Red takes gammons out of the equation for White.

You may be surprised to find that White should drop (just) this redouble. If White loses, he will trail 1-4 (Crawford) and being on an odd number reaching the Crawford Game is not a good idea. If White loses this game, he will only have 17% match winning chances. He does better to pass and play from 1-2 behind.
