One of several X-wings 179 gives r2c6=6, which solves it.

Play this puzzle online at the Daily Sudoku site

Yes indeed- the 167-XY wing also removes the 1 in r1c3 and this can also
be done by a W-wing on 17.

On the one hand- nice to get a double VH to end and start the month
On the other- Yet another 1 stepper (though with more than one
solution.....).
