Hi
See what happens when r5c9 or r4c9 or are not 1.

If r5c9 is not 1, it is 4 so r5c5 is not 4.
If r4c9 is not 1, it is 2 so r4c5 is 6 and r1c5 is 4 and again r5c5 is not 4.
=> -4 r5c5; stte
8-)

Hi Bat. This is a roundabout way of describing an XY chain : (4=6) r1c5 - (6=2) r4c5 - (2=1) r4c9 - (1=4) r5c9

Reading the chain from left to right this shows that if r1c5 <> 4 then r5c9 = 4 and reading it from right to left it shows that if r5c9 <> 4 then r1c5 = 4. So at least 1 of r1c5 and r5c9 must be 4 so r5c5 <> 4.
