Is this a Swordfish? (3271) contributed by Fred Tassin
Please help with daily challenging puzzle for #380.

Consider the possibilities for 1 in row 4 (columns 1,2,and 3. The possibility of 1 has been eliminated in column 6 of this row.)

Look at the possibilities for 1 in row 7 (columns 1,2, and 7)

Finally look at the possibilities for 1 in row 9 (columns 2, 3, and 7. The possibility for 1 has been eliminated in column 4 of this row.)



My first thought was this pattern formed a Swordfish, but if it does, then all possibilities for 1 are eliminated in row 1,because they appear in columns 1,2, and 3.

This obviousally can't be true, so is the pattern a Swordfish?

No fish? (re: Is this a Swordfish? (3271)) contributed by Georgina
I don't think you have s Swordfish there actually. They do seem to be very rare.

When I look for a X Wing or Swordfish I look for arrangements of a possible symbol arranged in a box. The key is seeing two in a row or column. In the X-Wing they form the corners of a box in the Swordfish there are three pairs forming two overlapping boxes. At a quick glance I can\'t spot the '1' s in your puzzle forming a box there seem to be three possible positions in the rows and columns.

Not straightforward (re: Is this a Swordfish? (3271)) contributed by Lynne
I can't see an easy solution strategy. There are quite a few straightforward squares to solve but it then reaches a stage when nothing can be easily solved. For example 5 must go in Aa as there are no other places a 5 can go in block Aa.

I think I'd need to do a trial and error strategy to solve it.

Good luck
