Very nice indeed! Here is the code for that puzzle. It gets 1.10. Wellbeback and Andrew are very good at that technique and use it much more often than I do. triple click code: Ed |

It is neat. It's ironic that I prefer this kind of move to combination analysis (which Andrew and Ed are better at than me), but in this case I would use combination analysis. I.e., 27(4) must contain a 9 in r1 -> 14(2) = [86] -> no 8 in 27(4) -> 27(4) = [6{579}]. However, I used exactly this move in Ed's latest Assassin 398! r4c23 = +15(2) -> Combination of that + 32(6) is greater than 45 -> must be a repeat which can only be r5c4 = one of r4c23. |
