H-wing ((xyz)m-wing)
(5=9)r4c9-r4c7=(9-8)r7c7=(8)r6c7 => r6c7<>5; stte


Great solution! It is simple and clean.

I, on the other hand, opted to search for almost naked triple patterns. I found one but it was long and messy, but fun.

ant(134=6)r8c789-(6=8)r9c8-(8=147)r623c8-(47=15)r31c7-(5)r2c9=(5)r4c79-(5=47)r4c23-(7=1)r5c2-(18=3)r5c9-r78c9=r8c8 => r8c5<>3
