Another excellent puzzle that could be solved logically, step by step, without using a chain.
Thank you very much Hepa!

 Hard for me
Setti 4 and 7 does not help, no fish in Sight
ABC2 cannot be high after a länger chain, then too much easy

Not so hard with Settis and CE; a short HC at the end, like Hel.
