It could be interesting if you forgo chains and pincer extensions.

Code:
 +-----------------------+
 | 2 . . | . . 3 | 8 4 . |
 | . . 4 | . . 6 | . . 1 |
 | . 1 9 | . . . | . . . |
 |-------+-------+-------|
 | . . . | . . . | . 2 . |
 | . . . | . 3 . | 1 . 8 |
 | 8 4 . | . . . | . . 3 |
 |-------+-------+-------|
 | 9 . . | . 6 . | 2 3 . |
 | 7 . . | 3 . . | 9 . . |
 | . 2 . | . 9 8 | . . 5 |
 +-----------------------+

Still looking to improve with chains or extensions but have found nothing. Hope someone else will have better luck.

XYZ-Wing (257) and W-Wing (56). At this point I noticed an X-Wing (7) but didn't play it. An XY-Wing Chain (56-57-57-57-67) finished it off and that depletes my supply of DAJ puzzles. I guess it's back to Menneske and Vanhegan!! Wink Laughing
