Assuming X-wing as basic move, from here:

XY-Chain: 3 3- r2c4 -6- r1c6 -9- r8c6 -4- r5c6 -6- r5c5 -7- r8c5 -3 => r3c5,r79c4<>3 ; stte

Assuming X-wing is not a basic move, from here:

Code: Select all: .-------------.------------------.-----------------. | 7 39 2 | 5 4 169 | 139 a69 8 | | 8 349 1 | 36 2 7 | 349 5 346 | | 6 5 34 | 13 39 8 | 13479 2 347 | :-------------+------------------+-----------------: | 3 467 467 | 9 1 5 | 2 8 467 | | 2 1 8 | 467 e67 d46 | 5 3 9 | | 5 467 9 | 2 8 3 | 47 467 1 | :-------------+------------------+-----------------: | 4 8 367 | 367 f3679 2 |g379 1 5 | | 1 2 5 | 8 379 c49 | 6 b479 347 | | 9 367 367 | 13467 5 146 | 8 47 2 | '-------------'------------------'-----------------'

Then 9- r1c8 =9= r8c8 -9- r8c6 -4- r5c6 -6- r5c5 =6= r7c5 =9= r7c7 -9 => r123c7,r8c8<>9; stte

As Luke said yesterday, different outcome but same cells and links, more or less ...

Code: Select all: 7 39 2 | 5 4 f169 | 139 e69 8 8 349 1 | 36 2 7 | 349 5 346 6 5 34 | 13 39 8 | 13479 2 347 ---------------------+----------------------+--------------------- 3 467 467 | 9 1 5 | 2 8 467 2 1 8 | 467 a67 4-6 | 5 3 9 5 467 9 | 2 8 3 | 47 467 1 ---------------------+----------------------+--------------------- 4 8 367 | 367 b3679 2 |c379 1 5 1 2 5 | 8 379 49 | 6 d479 347 9 367 367 | 13467 5 146 | 8 47 2

(6) r5c5 = (6-9) r7c5 = r7c7 - r8c8 = (9-6) r1c8 = r1c6 => -6 r5c6; stte

Your PM looks the same as the H3 wing but your chain has typos.
