Hi FEARDIZ,

Reading the introductory post to these threads might help.

New pattern: the Turbot Fish

Strong Links for Beginners

[TKiel]

Though multi-coloring is a good and very systematic tool, i want to say that in this case the 2 strong links in rows 3 and 7 are easy to spot (old name turbot fish or also advanced coloring with 4 cells)...So multi-coloring is not needed here.

I always had the impression that 'turbot fish' was a particular pattern of multi-colouring.

Yes, of course it is. What i meant is, that i would not start to color the strong links with BG and PA, observe that B and P are in the same column, conclude that G or A must hold the number and make the elimination then.
Instead i make it directly after spotting the 2 strong links (or the turbot fish).
