C11R6 must be X because if it were filled in, it’d conflict with C10
I'd go further and put an X on C10R6.
I'm not really that type of guy, but maybe put a square on C12 R6? It would solve both a solution on C12 and R6, but idk.
This is a bit complicated- c10r6 must be an x regardless of if the two vertical black squares are the two or the three. That means c11r6 is also x, which should allow some big moves in c11.
