This puzzle should be pretty easy for SQ.

Other solvers see xy and lots of Turbots.
SQ doesn't get it, yet Turbots are grouped-x so I expect that should catch it?

OK, I have uniqueness, colours and ER turned off.
Finned x should get Turbots.

With ER enabled, there are 5 Empty Rectangles found in this puzzle.

3 of these are also caught by Finned X-Wing, but one of them requires coloring (Color Trap). Finned Fish cannot replicate all coloring/turbot moves, but ER is a very simple and productive technique, which you may want to enable.

The XY-Wing has a BUG alternative.

Thanks Ruud!

I now have ER on, it catches Turbots just dandy!

ER catches some finned x-wings.

Yep, I am a convert, ER does solve things, but it is nearly as bad as colours to use.

I don't like it much, it is pretty usefull!

well i read the doc's i read the glossary
i go to sudocue and i think ER is empty rectangle.

I'm not yet sure what ER is but I have vauge ideas.

Now playing with it for a while...
ER is the way i was finding x wings that werent

i guess you need er's a bit stronger to qualify as x-wing

All the links to the online help... are making me more confident
or perhaps bolder.
