I initially found a nice BUG-Lite+2 (238)r89c259 external SIS r8c3=3,r6c9=8; r9c9<>8=2
BUG-Lite(238)[(8)r6c9=(3)r8c3]-(3=8)r9c2;
However, it was not very productive. So I tried again a found a one stepper...........
Flightless xy-wing -459 with transport: (4=5)r7c5-(5=9)r5c5-(9=1=4)r5c79-r12c9=(4)r2c8; r2c5<>4=9

Peter, I enjoy those short, right-to-the-point "almost" moves. This one is especially nice...........
