Two of Rebecca Bean’s Less Extreme


Here the Rebecca Bean Extremely Hard review closes with a line marking finish and an easy coloring. The collection is far from extremely hard, if the sample of 12 pre-selected for this review is typical.

On the way to line marking, 9-6 of the previous post gives up an unremarkable bypass, but does offer an unusual box marking.

 

In line marking, the  c4 creates a naked pair in r9, suddenly reducing 5 to one place in the SE box, a hidden single.

 

 

 

 

 

The trace pattern of the collapse is kind’a remarkable as well.

Puzzle 11-6 is less flamboyant, but illustrates well the idea of jumping into Medusa coloring when the bv field is generous.

A vigorous bypass runs out of 3-fills, but leaves pairs. Box marking is tame. In line marking, a naked triple calls attention to the hidden single NE6.

 

 

 

 

 

The rows finish up. Going directly to coloring, traps add bv and the cluster expands.

 

 

 

 

 

 

 

In the second round, an uncommon trap, as 2r3c7 is dispatched by blue or green. As 2r4c7 turns green, 8r4c7 is trapped, turning 8r1c7 green to banish the entire green army. That’s enough to finish 11-6.

Even though Rebecca’s collection doesn’t live up to the extreme label, you can certainly  enjoy the 588 other puzzles. You won’t know when the bypass will prevail, or exactly what advanced technique might be required, but some interesting turns can be expected.

Next, I have another example of the AIC slink. It’s a redo of the first puzzle pre-selected for the KrazyDad Insane review, the volume 4, book 1 #5. You’ll find it on the post of 7/16/13. I still consider the KrazyDad Insanes my most challenging collection.
