BBDB for me...
Quote:
x-wing(5) ; r27c8<>5
x-wing(1) ; r138c2<>1, r4c8<>1
xy-wing(48-6) r6c9 ; r4c5<>6
xyz-wing(37-4) r9c2 ; r78c2<>4
xy-wing(15-2) r3c12<>2, r2c8<>2
Looks similar to JC's but used another wing somewhere...

Peter, we have the same proof Exclamation
The only difference is that the XYZ can be done before the 1st XYW. Congratulations !
BTW, I much appreciate the proof of the A puzzle as I consider Fish as belonging to SSTS ! Therefore, the less length of an AIC the better ! That 's why I highly appreciate Daj's puzzles : they help me to be trained at systematically find short length AIC !
