Can anyone solve this with logic?

I've tried all the tricks. Had to resort to guessing.
Got this far

_ 1 5 8 2 _ _ 3 7
_ _ _ _ 3 _ _ 8 _
_ 3 8 9 _ _ _ 5 _
1 7 9 _ 5 _ 8 4 6
8 5 4 _ _ _ 2 9 3
6 2 3 4 8 9 1 7 5
_ _ 2 _ _ 8 7 1 _
_ 8 1 _ 7 _ 3 6 _
_ 4 _ _ 9 _ 5 2 8

Thanks

I ran your puzzle through Simple Sudoku and the most advanced features it used were two Naked Triples and an XY-Wing to remove a '6' from R9C3.

Thanks. I found the naked triples, but I'm not seeing the xy-wing that allows removing the 6 in r9c3. Please open my eyes Smile

. Thanks
