Today's tough puzzle includes excellent examples of short Forbidding Chains, or Alternating Inference Chains. Naturally, I could
not resist blogging this one.

Is this a photo GannieMo may have taken. Good old Perth, Western Australia on the map with the Swan River running through the middle. Great photo.

How pretty, that's a really neat photo.
 |  |
This really was easy. Best time ever, under 20 mins. Pretty city
 |  |

That's an amazing shot!

12:15 Maen Easiest tough in a while....
 |  |
wombat, wish I could say the same.. maybe I will start reading the sudoku blogs
 |  |
No guesses today.
 |  |
used the possiblities option and it screwed me up. i do better maintaining the possibilities in my mind! 28 mins + change with some guessed mistakes.
 |  |
11:38 Easy
 |  |
Wonderful view and cute shot.
Good maEn to all.
 |  |
15:35; easy only because I didn't need to guess.

Not too hard but a challenge. lots of givens and reduceables. A couple of bivalue chain reductions and then I got lucky, I did a chain that went to every cell so every candidate in the chain was correct. Another excellent airplane photo. I don't think I've flown since owning a digital camera :(

Hi everyone. Yes Anne, I did take this one as we left Perth and headed for Bali.
I also took the one of the cloud shown on Saturday last. The funnel of cloud was forming as we flew over Java on our way from Bali to Singapore. To avoid any reflections turn off any flash on the camera.

Good afternoon to all! Great photo Mo, as were the other two. Perth looks really big from this perspective!

great photo GannieMo

Nice Photo GannieMo.
The two Bridges over the Canning River.. The bigger Bridge is Leach Highway, and the smaller Bridge is Shelley Bridge. Nice picnic area between the two bridges on the river foreshore.
The Bridge in the top left distance is Mt Henry Bridge.

The big Bridge is Shelley Bridge (on Leach Hwy) and the little bridge is the (Old) Riverton Bridge....
