I really enjoyed this puzzle, probably because I found a three cell pseudo-cell for a xy-wing.
Quote:
x-wing 3,
finned x-wing 5, both in the row and the column,
xy-wing 136 with pivot 16 in r8c5 and pseudo-cell 13 formed as a chain 12-26-63, (I later realized that a w-wing 36 makes the same deletions.)
simple coloring on 2

I had a couple of X-Wings, two ERs, a simple and multi-coloring, a W-Wing and XY-Chain.
