8/14/12 Pattern Enumeration Stuart’s pattern lettering and freeform technique examples are adapted from Logic of Sudoku. Stuart produced good examples, but did little else with these fundamental ideas.
11/06/12 Digital Forcing Chains? Stuart’s arbitrary choices of bv and value can generate an almost nice loop, and when it becomes a “Digital Forcing Chain”, it has done that. It’s simple trial and error.
11/13/12 Nishio Forcing Chain? Doing the guess, and carrying it out by an AIC, changes nothing.
11/27/12 Cell Forcing Chains Exploring what every candidate in an arbitrarily chosen cell “sees” via forcing chains is obviously not a practical option for humans.
12/11/12 Unit Forcing Chains A similar humanly impractical idea. Its reverse is sometimes recognized, when a candidate is seen to remove all candidates of a number from a unit.
2/05/13 Grading the Master Class Calls out the hyped title, citing the actual level of instruction offered.
2/12/13 Tom Sheldon on Sudoku Solving Disputes pronouncements, and critiques unexplained theorems
4/9/13 Starting With Stephens From Week to Week and Sudoku Addict’s. Bypass, then a long number scan for candidates, with no slink marking.
4/16/13 Advanced Stephens Just subsets and boxline. Beyond is “extreme”.
4/23/13 A Bv Scan of Week 48 Demonstrating some of what Stephens misses.
4/30/13 Extreme Stephens Advanced Sysudoku, but without Sue de Coq, APE, Medusa coloring or AIC, and limited to regular fish. Then Nishio.
5/14/13 To Nishio or Not to Nishio Using Nishio to survey for grouped ANL
11/19/13 Pulling Rank Explains rank = 0 example as and AIC ANL.
11/26/13 Higher Rank Theory Explains rank > 0 and identifies SudokuOne rank = 3 example as a quadruple Stuart cell forcing chain.
12/03/13 Rank’s Little Gotcha Rejects setlink mixed rank theory for human solving. Displays Barker’s GN first removal SLG, with about 50 remaining for the solution.
6/03/14 Hanson’s Sudoku Assistant Hanson’s “generalized method”
6/10/14 Basic Solving with Bob Completion strategy, singles and boxline
6/24/14 SA Finds Locked Sets Sysudoku covers what Hanson leaves unexplained.
7/01/14 Bob Goes Regular Fishing Hanson’s grid analysis, with many errors. Student Assistant uses the suset algorithm .
7/08/14 Bent Naked What? Hanson’s explains the XY-wing and XYZ-wing using a complex strategy he claims to explain later. It’s not a subset, as Bob labels it.
7/15/14 Hanson’s Bent Naked N-Set Sysudoku explains and renames the complex strategy, proving Bob’s BSN1 and BSN0 rules. Applications other than the wings have not turned up.
7/22/14 SA ALS Toxic Sets Single common ALS toxic sets and double common locked set. The latter is new.
7/29/14 Finned Fishing with ALS Catching finned fish by ALS, by the suset algorithm.
8/4/14 Checkpoints on Suset ALS Kraken Fish Amazing f sashimi and kraken fish by suset analysis on Hanson’s example. Bob doesn’t kraken.
8/11/14 Hanson’s Polarity ANL A defined method crafted from Hanson’s Almost-Locked Range, best applied with coloring.
8/18/14 Hanson’s Strong and Weak Hinges Gives up on Hanson’s muddled chain theory and explains hinges logic as AIC
9/30/14 Gordon’s Basics Guide Singles search, with dublex and cross-hatch, then number scanning, subsets and boxlines by example. Then an awkward slink marking.
12/02/14 Gordon’s Fishing Guide Offers no help on regular fish, and doesn’t cover anything else.
12/09/14 Gordonian UR-ology Gordon’s renamed, though already well-known UR methods.
12/16/14 A Gordonian Fantasy Gordon’s loosely described Gordonian Polygon is defined for him.
12/23/14 Plus and One-Sided UP The Unique Polygon is defined (and renamed) to include Gordonian Plus and One-sided variations.
12/30/14 Extended Gordonian Overreach Gordon’s renaming of extended UR and his imaginary “Gordonian Rectangle Wing” are rejected.
1/13/15 Wings and Chains With the Guide XY-wing as a forcing chain, regular XYZ-wing with an incomprehensible “buddies” rule, a formula for turbot fish, nothing on X-chains.
1/20/15 Cycling Blindfolded Equally overspecialized and inept on AIC, and “bilocation graphs”. obsolete by coloring. Omits XY-chain ANL.
Denis Berthier So far, scattered comments and no overall assessment.
12/27/11 xyt-chains A way to start an XY chain. The post defines a “skip rule” to prevent the extended XY-chain from becoming a truth net, an aid for trial-and-error.
3/06/12 XY-loops “are useless” Berthier gets wrapped up in restrictive definitions and loses his way on XY-loops, missing a very useful human solving tool.
