A nice one-step wing...

I'm not familiar with Ted's Type 1 Bug Lite terminology, but maybe mine was the same thing since it made the same elimination.

There was a potential DP in boxes 123, 58-58-45-45-48-348. The 3 must be played to avoid the DP.

Marty, I have to admit that I am not sure about the " Type 1" label, for a BUG_lite. In any case we found the same pattern & deletion.
