2020 - Position 32

Money Play. Should Red redouble? If redoubled, should White take?

This another position where Reichert’s formula works to perfection. Clear redouble, clear take.

Formulas take the hard work out of calculating positions like this one from first principles. They are correct a high percentage of the time and good players know how to make allowances for exceptional circumstances.

It would be a 1.5 blunder not to double and and a double blunder to pass.
