Could you confirm if <17> <78><18> is a valid XY Wing eliminating the 8 in R5 C7.
Just trying to learn how to recognise them
Thanks

I got as far as the above and then did a UR 49 in r7c1,r9c1 r7c4 r9c4. This means r7c4 must be a 6 the rest then dropped out is this valid
Thanks

Hi Marty,
Thanks for the prompt reply, I had looked at Brainbashers and understand the concept but could not see it in this particular puzzle
More practice is needed I will work through some more ... |
