Play online at the Daily Sudoku site
Another way of solving this:
If r4c5=3
then r5c5=9
also r4c8=8, r4c1=4, r3c1=9
this leaves no room for a <9> in r2 so r4c5 must be <7> |

Hi everyone,
W-Wing
7,9 in r2c3,r9c2 SL with number 9 in r39c1 and -7 in r3c2,r9c3
or
7,9 in r3c9,r9c2 SL with number 9 in r39c1 and -7 in r3c2
Ciao Gianni |

Pincers for 9 at r6c2 and r9c1 so r9c2 < > 9
(9=2)r6c2-(2=4)r5c2-(4=8)r4c1-(8=9)r9c1
I see this as a simple xy chain but you could see it as a W-wing with an SL on 4. |
