This is your puzzle,I think....

Code: Select all

                                     
   +----------+----------+---------+ 
   | 6   3   4| 2  1   5 | 9  8  7 | 
   | 9   1   8|34  37 467| 2 56  45| 
   | 5   2   7| 9  8   46|46  1  3 | 
   +----------+----------+---------+ 
   |147  79  5| 8 469  2 |46  3  14| 
   |148  89  2| 5 469  3 | 7 69 148| 
   | 48  6   3| 7  49  1 | 5 29 248|

   | 37  57  1| 6 237  9 | 8  4  25| 
   +-------------------------------+ 


Next steps need 2 XY wings or also called Y-wing:
XY-wing [3 cells] (9)(9=8)r5c2-(8=4)r6c1-(4=9)r6c5 => (-9)r5c5
XY-wing [3 cells] (9)(9=6)r5c8-(6=4)r5c5-(4=9)r6c5 => (-9)r6c8
stte (singles to the end)
