Hello again! So this might not be the shortest way but here's what I've got:
Black: H10, White: F10
Black: K10, White: J10
Black: M6, White: L7
Black: K7, White: K9
Black: K4, White: K5
Black: L5
Then N7 and I2 are open for the win!
P.S. it was definitely better to do it visually then to do it in my head, I just used MS Paint xD
Very well done! :-) Send you reward!
PS Do you like the win?
That was a great puzzle, a lot of fun to solve. Please do more of these, I will keep resteeming!
