The Olive Side of Fata Morgana

This post illustrates with Fata Morgana the practice of taking both sides of a trial, to be sure that a contradiction is found.

The  bv scan with a bv map yields only an indecisive ANL.

The expected contradiction appears as the marking places a second 2-candidate in the NW box.

Next, we revisit Wex 435, the puzzle concluding the recent Weekly Extreme review. An independent analysis by Gordon Fick shows that it doesn’t require pattern analysis, only a good eye for AIC. An acquaintance with kraken fish and coloring doesn’t hurt, either.
