I debated qualifying it as BBDB as VH+. I may do so in the future.
Bottom Line: Advanced will alway appear if necessary in my solver's solution. |

I started with a xy-wing 23-9, but my second move was identical to the xy-wing posted by Keith.

I missed that extended XY-Wing (which I usually call an XY-Wing Chain). I played an XY-Wing (293) + pincer transport, then a five-cell XY-Chain. |
