BUG: Learn Chess, Bishop second stage

There are two correct solutions: a2, b1, d3, b5, e2, d1 (works) and d1, e2, b5, d3, b1, a2 (doesn't work). After d1,e2 it isn't possible to move to b5 and you are force to take on d3.

There's no bug. It's intentional.

You can't jump over stars with the bishop.

They symbolize pieces so in that line from e2 you can't take on b5, the same as for example you could move the bishop to f3 but not c4 from that position.

Oops, of course
