I'd be interested in your thoughts...
I most like a [cryptic] crossword that follows the following rules:
a). I can complete it (eventually)
b). It makes my brain hurt a little
c). Takes more than one day's attention to solve.
For example, this weeks EV was perfect, a brain-hurting two-dayer, but most Speccies, neat but too quick.
While difficult EV's, or more difficult ones than even that are, to my small brain, undo-able therefore unsatisfying.
So I ask, out of interest, what makes an enjoyable puzzle for you?
