Would having the ability to quickly find claws between encrypting half
way and decrypting half way be useful in cryptanalyzing a block cipher?
way and decrypting half way be useful in cryptanalyzing a block cipher?

I'm not familiar with the term "claws", but encrypting half-way and
decrypting half-way is the reason that the block cipher Double-DES
(security parameter 57 bits) is so much weaker than Triple-DES (security
parameter 112 bits).
