Two steps.
Quote:
flightless xy-wing 78-9 with vertex in r6c5 and pincer transport: (9)r5c6 - r8c6 = r8c7; r2c7<>9,
which opens up an AIC: (7=8)r1c9 - (8=3)r2c7 - (3=1)r2c4 - (1=5)r2c1 - r8c1 = r7c2 - (5=7)r6c3 - r4c3 = r4c78; r5c9<>7

This took me a long time and it took six moves, nothing out of the ordinary, and ending with an XY-Wing on 457.
