Thanks Pat, I've just noticed this. Very clear! - I'll try.

PS 1. Hi Tim, thanks for pointing out the mistake. I see that you too use Andrew Stuart's excellent program! (It's maybe a bit lazy, but I often use it to dash through the basics, print out that sh ...

Many apologies for the mistakes. I was copying from my 'post-basic' sheet & (a) forgot that a couple of 4s had been filled in (b) very carelessly left out a 3. (I promise that if I post again I'l ...

JC, as I said in another post, that's seriously clever.

I'm going to work through your solutions, though they're at or beyond my limit of understanding. Anyway, thanks!

Thanks, I'll try that.

I think I've seen people using URLs embedded in a word. I've read the Sticky that says how to get the URL for a particular message, and managed that, but I can't figure out how to embed it in (for in ...

Keith suggested posting puzzles that seemed to need a swordish:

Marty & Keith, I'm glad I'm not the only person who dislikes complex swordfish patterns - I thought I was a bit wimpish. Soon after the sudoku craze started (04, 05?) I was given a book of puzzle ...

Thanks JC & Ronk. Both seem good, but since I'm all for brevity I'll probably go for Ronk's, which matches what I do myself when I'm writing down moves: I write a subscript UR under the =.

Or, using the UR (AUR?) 28, r14c79:-

3r4c7 = 1r4c79 - r6c89 = (1 - 3)r6c5 = r6c3; r4c1 <> 3

(Yes, I know I should stick the letters UR or AUR in there somewhere, but I haven't yet quite fi ...

Keith, thanks for the lesson. I should have known this (maybe did at the back of my mind).

Ronk, thanks for the turbot fish idea - very pretty - I'd never have thought of that. But I don't think ...

Many thanks. Well, I'm still a bit befogged, but it's given food for research. (You're talking concepts that are unknown to me. Well, I had heard of turbot fish but, perhaps wrongly, assumed that th ...

You guys are fast workers!

I used the ALS pair A = (6,7)r1c5 , B = (3,4,6,7) r3c356, doubly linked by 6 & 7. r3c8 <>3, r12c4 <> 6. Followed by a UR type 1: r2c4 = 4.

I'll study ...

I guess I'm being silly. I didn't want to post the complete puzzle because my sheet is so scribbled over that I thought I'd wait until I got home & restart. But here it is, hopefully correct. (I ...

Hi. I introduced myself in the theory forum & said that I'd post a few Menneskes. Before going on a short trip I ran off some post-basic sheets of Menneske 'impossibles', and here's one. I can't ...

Thanks Ted. Unfortunately, I didn't explain properly - my fault. The 6s in r2 & r9 aren't strongly linked. Perhaps I should just have put up the whole puzzle.

This is an atypical example. I'v ...

Hi. Several years ago I was persuaded to try this site & quickly got hooked. But I was very busy at both work and home & reluctantly gave up after a while. (I wish I'd joined then, and persev ...
