I’ve retried 3 times and I always get a checkerboard pattern between the 7 and the ten at r5/6 c4/3. I can’t see where I’ve made a mistake and that’s the first time it happens after so many tries ! Especially since Cave is a style I’m pretty familiar with. I’ll try again in the morning, this is so strange
Nevermind, I just don’t know how to count. I should go to bed.
