I followed this path:
 
 
2-String Kite with number 7 in r6c58, r58c4 and -7 in r8c8;
 
Empty Rectangle with number 7 in sector 9 connected with number 7 in r37c3 and -7 in r3c9.

				Hi everyone
 
 
R9C9=8,R6C1=3,R6C2=5,R9C7=5,R8C3=5
 
 
Delete 7 in R3C9, since if it were true would impose no 7 in column 7 (contradiction) . Finally solution with basic strategy.

				| Kudos to all. You have all amazed me (again). I simply cannot SEE all of your great solving techniques. I will have to digest them some more. I used a finned XY-Wing (146) r12c14 in which the wing proved false, leaving the fin (6) as true in r2c1. Solved with basics from there. |

Gianni,
 
 
I don't see an ER in box 9. Perhaps we have different understandings of that technique |

				Hello Marty, maybe it's not a textbook example of an ER, but once the 7 is removed in r8c8 (by the 2-string kite), the 7 can also be removed in r3c9 because it sees both 7s in c3. One directly (same row), and the other through Box 9. Is that not the ER technique at work?

OK.
 
 
I was looking at it as a one-stepper rather than as the the 2nd move of a two-stepper. |
