I went the chain/wing route - for four steps.

w-wing-like(25) ; anp(51=2)r4c47 - r4c2=r9c2 - (2=5)r7c3 ; r4c3<>5
xy-chain/als ; (1=2)r2c4 = (2=1)r2c1 - anp(1=29)r9c12 - (2=5)r9c7 - (5=1)r4c7 ; r4c4<>1
xyz-wing(23-5) r8c9 ; r7c9<>5
xy-wing(35-2) r8c9 ; r9c123<>2

I'm happy to have completed this, but it took about triple the moves that Peter used.

I am in the same boat as Marty.

It was really great fun to solve, using lots of different type moves. At some point I stopped noting my steps and just enjoyed the ride.
