				Hi everyone
 
 
[(2)R1C7-(2)R23C7=(2)R3C5-(2=8)R2C6 and (2)R1C7-(2=6)R1C1-(6)R46C1=(6)R8C3-(6=8)R6C6]=>contradiction two singles 8 in column 6=>-2R1C7=>stte
 
or
 
AIC (2)R8C3=(2)R8C1-(2)R1C1=(2)R2C3-(2)R2C6=(2-6)R4C6=(6)R4C1-(6)R1C1=(6)R1C7-(6)R2C7=(6-2)R2C3=>-2R2C3=>stte
 
 
R1C7=2 and R2C3=2 are in any case biunivoca.
 
 
Ciao a Tutti
