Similar for me - though with an ANP in the middle instead of the w-wing ..

Quote:
x-wing(5)
kite(4) r1c2<>4
ANP(58) (58=9)r56c7-(9=5)r4c9-(5=4)r4c3-(4=5)r2c3; r2c7<>5
xy-wing(589) r1c2; r3c6<>5

I knew I turned this into a BBDB, but it was probably due to sequence. Suffice it to say that I played an X-Wing, M-Wing + pincer transport, Finned X-Wing and a Hidden UR before an ER opened up a puzzle-ending XY-Wing.
