The opening basic moves certainly get you pretty far into the puzzle, but I don't see how you can get past here without using an x-wing.

A little something until the next Very Hard shows up here. An interesting puzzle from BrainBashers that didn't (as usual) require a UR before the puzzle to fall apart.

It opened up with either a s ...

How did you get the 6 in row 4, column 2?
