From the original puzzle above I worked through a unique loop and wound up here.
I think this is a swordfish with a fin at r7c7 and a removal candidate at r2c2.
Or -- is r7c7 a fin to an x-wing with r3c8 the removal candidate?
Or -- is it both?
Or -- neither?
I am having difficulty getting my arms around swordfishes and their many patterns.
