I played this position many times, but can't claim to know how to win - any suggestions?

Black to move.

Here is an interesting position, right from the game, one side is trying to steal the too advanced checker, the other side, while defending it, is mounting an attack on the left side. Normally in such positions black move 1.10-14 forcing the 2...25-22 to get a draw.
But here we also have a hidden gem move 1.12-16! What is really interesting is that my Aurora program repeatedly answers 24-20, can someone show why 24-20 is bad?
