Just try the pattern in this thread op puzzle.

I don't see it. Simpler if you just show me what you mean.

Forget about it and try to find L3-Wing example puzzles if it is similar to it.

Forget about it and try to find L3-Wing example puzzles if it is similar to it.

I don't have the tools to look for specific patterns (that aren't contained in the Hodoku technique set). If I spot an L3-Wing it's because I found it as a chain, but I'd never look for L3-Wings or almost any other patterns specifically. In the op puzzle I can easily see one (but it doesn't contain the combo pattern):

L3-Wing: (4)r1c2 = (4-3)r4c2 = (3-2)r4c3 = (2)r1c3 => -4 r1c3

Hi SpAce,

Not sure, but, this puzzle might have required L3-Wing.

Google [sudoku "L3-Wing"] and found many links from sudoku.com.au site that contain mostly JC Van Hay puzzle solving path with L3-Wing move.

Added as on 20190501: By the way, after rethinking, additional -X @ r2c2 & -Y @ r2c8 eliminations have no significance because they both have strong links, i.e., X @ r28c2 & Y @ r28c8 and default eliminations -Y @ r8c2 & -X @ r8c8 from bi-value cells will produce naked singles X @ r8c2 & Y @ r8c8.
