Inspired by two 1200 players

I was skipping through Game 8560044 otg - reboot RHP 2007.


Here Black can just win the Rook with Bc7+ instead he played another move.
A relieved White chopped Rooks and it kicked off a charming win because
(perhaps) the players did not know that Bishops of opposite colour always draw.

Using the same idea I composed this.
It's probably been anticipated with a more complex setting.




On another thread people are asking what good are computers?

I leaned heavily on the Tablebase here:

To get it sorted and make sure it was correct.
