Sorry for jumping in without a puzzle submission, but this one blew me away! After many, many STSS + forcing chain iterations (18 chains with STSS tossed in between when useful), I cleared some singles one locked set... then look what jumped out of the Suduok sea:

Code: Select all: 358 34 568 | 49 179 479 | 68 12 256 569 79 1 | 2 8 3 | 4 59 5679 47 2 89 | 5 14 6 | 789 3 179 -------------+---------------+------------ 489 5 3 | 4689 2 489 | 1 7 469 1289 14 289 | 689 57 57 | 369 24 369 249 6 7 | 1 3 49 | 5 8 249 -------------+---------------+------------ 1579 8 59 | 3 459 2 | 79 6 14 356 39 4 | 7 56 1 | 2 59 8 2679 17 2569 | 489 569 4589 | 379 14 3579

The next move my solver found is a Leviathan on 9's; first time I've ever seen one of these!! Found in r1345679c1345679 and results in r2c19<>9.

Still doesn't crack the puzzle, but it did make me stop testing and stare for a minute. (FYI, my solver needed another forcing chain, singles, 2 patterns, a locked set and final forcing chain to reduce the puzzle to singles & a solution).

Cheers...

IMO it should find the x-wing c28\r28 instead.

Quirk of how my solver works; it checks for row fish before column fish and stops when it finds the first one. So when it hit the Leviathan it stopped looking. I could change it so it looks both ways and takes the smallest one it finds, but I probably won't (at least not anytime soon). Most of my logic solving code works this same way; picking some path and finding the first (and smallest) one it can along that path.

Thanks for pointing it out; I'll keep this shortcoming in mind next time I am tweaking the current code. I am, nonetheless, still smiling about seeing my first Leviathan, even if it was quickly harpooned by a little X-Wing.

Cheers...
