XY-Wing 29 23 39 pivoted in r5c6; r4c2<>9 solves it.

With my usual reluctance, it solved with basics, both with pencil and paper and then on Draw/Play.

After the basics I have the same Grid as shown by arkietech above. I can't see more eliminations by using basics only. I might not be seeing the obvious.

OK, on try #3 basics didn't do it. XY-Wing (293); r5c3<>3.

One frustrating thing about Sudoku is that one often can't learn from his mistakes because I have no idea what I did wrong the first two times.
