This should qualify for one of those effortless extreme threads, or the like. It reduces painlessly to a BUG+3 grid (well, if you consider naked quads painless), at which point it is easy to see that r1c3<>3, solving the puzzle. Nicely done, Mauricio.

here's a 7.1:

Code: Select all: 3 . . | . . . | . . 6 . . . | 8 . 1 | . . . . . 9 | . . . | 8 . . ------+-------+------ . 7 . | . 9 . | . 5 . . . . | 6 . 2 | . . . . 8 . | . 3 . | . 7 . ------+-------+------ . . 2 | . . . | 1 . . . . . | 3 . 5 | . . . 9 . . | . . . | . . 2

and to fill in the gaps a 6.6:

Code: Select all: 1 . . | . . . | . . 5 . . . | 9 . 7 | . . . . . 3 | . . . | 4 . . ------+-------+------ . 9 . | . 8 . | . 4 . . . . | 6 . 2 | . . . . 7 . | . 5 . | . 3 . ------+-------+------ . . 1 | . . . | 8 . . . . . | 4 . 8 | . . . 5 . . | . . . | . . 1

I do have a 7.2 but i think JPF should be given a chance to post it :!:

Thanks ab, here is my 7.2, as agreed

Code: Select all: 1 . . | . . . | . . 2 . . . | 3 . 4 | . . . . . 5 | . . . | 6 . . -------+-------+------- . 3 . | . 2 . | . 7 . . . . | 8 . 6 | . . . . 4 . | . 1 . | . 8 . -------+-------+------- . . 6 | . . . | 1 . . . . . | 7 . 3 | . . . 8 . . | . . . | . . 5 ER=7.2

but :
1. a 6.6 has already been posted
2. what about this wonderful 6.8 ?

Code: Select all: +-----------+ |1..|...|..2| |...|3.4|...| |..5|...|6..| |---+---+---| |.7.|.6.|.8.| |...|1.5|...| |.8.|.9.|.4.| |---+---+---| |..3|...|5..| |...|8.7|...| |6..|...|..1| +-----------+ ER=6.8

ab, I can't resist giving you this 24 steps inferior puzzle

Code: Select all: +-----------+ |1..|...|..2| |...|3.2|...| |..4|...|5..| |---+---+---| |.6.|.4.|.3.| |...|7.8|...| |.9.|.1.|.7.| |---+---+---| |..8|...|4..| |...|6.9|...| |2..|...|..1| +-----------+

hmm not what i expected! the reason I deferred to you JPF was that my 7.2 was directly derived from your 4.2 puzzle by changing one clue:

Code: Select all: 1.......2 ...3.4... ..4...5.. .9..6..7. ...8.2... .3..1..4. ..8...6.. ...7.3... 2.......8

You can also switch the 9 and 5 in r4c3 and r3c7 for another 7.2.
