W-Wing: 36 in r1c4,r5c3 connected by 6r3 => r5c4<>3;stte

The bivalue cells are r1c4 and r5c3 (candidates 3 and 6). The strong link is for candidate 6 in row 3 (row 3 has only two possibilities for candidate 6, which means, that if one of them is not set, the other has to be set - strong link). One end of the strong link sees r1c4 the other sees r5c3. Candidate 3 can be eliminated from every cell that sees both r1c4 and r5c3.

Grouped Skyscraper in 3's in cells a-b-c-d => - 3 r5c4; stte

I did this in 3 moves following the path of least resistance at each point. Only the 3rd move is required but in casual solving it would be reasonable to look for the Swordfish.
