Hi Buzzb, whether 60% or 90% cold-solving isn't really what I was getting at. In a multi-phase puzzle, the cold-solving adds onto the time required. In addition some solvers, myself included, prefer crosswords where the crossing entries consistently give assistance to other clues. Having said that, I usually enjoy radial puzzles, which often require a good deal of cold-solving. I didn't discuss 'fairness', that's a notion I don't spend much time thinking about.
Finally I got a bit of peace and quiet this morning, and am now beginning to contemplate letter shifts. Prior to that, if anyone could confirm a few things, that would be very helpful.
I'm still not sure that my answer for 23 is the right one, since I'm unable to explain the wordplay. I have CAECA.
My 4 unclued squares are, in sequence, R+ENEK, S+B?EF, F+?DRE and T+RAER. Are these correct so far and are they intended to represent real words ?
