Right Cut / Left Cut
Recognition Tips
Bad cuts; aligning birds breaks squareshape.
Algorithms
Best Alg: 0,-1/4,-2/3,0/-4,-1/-2,1/-3,0/-1,0
Preserve bird on bottom, send whale from top to form matching axe/axe; doing CO into 3E/3E is also decent.

This case is its own color mirror; use best alg above.
