Not easy, I wonder why there is no discussion. Shortest way I found:
Swordfish 3, swordfish 8, UR on AB56, UR on FH89, x-wing 1, Setti 4.
From there, I am quite sure one chain is needed (e.g. E9==7 soon leads to contradiction)

 What are ideas for a solution? Where are the URs. I could only exclude some numbers from A1 by trying some combinations in \, row E and row F.

 I was lucky with the correct AB4 assumption. The rest follows easily.

 However, I needed several chains to disprove the other alternative for AB4.

 Very hard one for me. I used several chains to decide A1 (=1) and h/l column 1. Row E, F, column 4 and \ were key for me.
