I knew JC and Dan had one-steppers, but I couldn't find one and solved it the old-fashioned way, a UR sandwiched between XY-Wings, both of which required pincer transports.

Another one is a four step but simple.
The three UR's: 13 in r12c27; r3c7<>13, 17 in r38c89; r3c8<>1, 56 in r37c46; r7c4<>56 leads to BUG+1; r6c4=1 Very Happy
