Please sir,

I have been trying to follow your solution. But I am not able to follow your work from puzzle 1 to puzzle 2.

Specifically,
row 1 column 5 (-3); why?

puzzle 2 to puzzle 3.
row 8 column 6 (-2); why?

Thank you in advance.
Ema Nymton

Hi Ema Nymton,

I followed this path:

from puzzle 1 to puzzle 2
after XYZ-Wing R9C3=8 -8 in R1C3 and we have a Hidden Pair 4,8 in r1c15

from puzzle 2 to puzzle 3
after XY-Wing R6C4=4 R4C5=3 and we have a Naked Pair 2,7 in r46c6 and -2 in R8C6

Ciao Gianni
