Hi, I'd appreciate some help with the Times 4500. I normally do these with no PM, but this one stumps me. So if anyone can see the wood from the trees I'd appreciate the guidance. The starting position is:

Code: Select all

 
... ... 5..
..1 ..8 ..9
93. 26. ..1

..4 .5. ..8
.2. ... .4.
5.. .1. 6..

8.. .97 .56
7.. 1.. 2..
..9 ... ...


I reduced this to:

Code: Select all

4.6 9.1 5..
251 .48 .69
93. 26. ..1

..4 .5. ..8
.2. ... .45
5.. .1. 6..

8.2 .97 .56
765 18. 29.
3.9 526 8..



I can see the x-wing in 3s but I'm not seeing how it helps. Maybe it doesn't.

Help much appreciated.

Thanks

yes, it is the X-wing

Thanks Pat.
