Another single-stepper is a type 1 UR on 34.

Another move, a little off the beaten path, is the Hidden UR on 46; r6c9<>6.

I may be wrong but I thought it was a Type 2 UR on 34 (a rare find for me).

Cgordon:

All the literature I'm reading describing URs and all their variations say we are looking at a type 1 UR on 34 in r48c12. If its more subtle than that, point it out and I'll stand corrected.

The 34 UR is a Type 1 on my grid as well. I wonder if Craig has a 9 in r8c1. If yes, check for a 2679 quad in c1. But regardless, the Type 2 looks like it would work as a one-stepper too.

Yes - you're correct. I finished prematurely.
