Alfred, h3 is not 8. b7 is, though.

Standard techniques UP 31
1. (5=7)c4-(7=4)c1-b1=b56-a56=148b56c5 =>c5<>5 UP 60
2. XY-wing (8=9)b7-(9=6)b3-(6=8)h3 =>h7<>8 UP 81

Another way to write the first step in the other two solutions:

(4=213)ahi5 - ((1 or 3)=674)ahi6 => a29|b56 <> 4

(29) 45@g56=>g56<>3
(32) 2?@a5=>i5=1=>{h5=3&b6=1=>f6=3=>[d4=5=>c4=7&g6=5=>a6=4=>c9=4]}=>c1={}=>a5& LT;>2
(61) 8?@h3=>[b3=6&h7=9=>a9=9]=>a2={}=>h3<>8

some of the MW-x series solved, excellent paths by peterj, MW-9, MW-8 somewhat better than mine.
MW-4 (almost the same)
1. [(1)e1=*(4)d3-SS(4)a36.e6d45=(4-1)a5=a3] - (1=9)c1
aals(379)e1de3 # -9d1

// SS(2)dc7.ce6; -2d45.e9

no attempts were ever submitted for the 10/27 puzzle
site puzzle, SG @ UP=26, FAIL; SE=9.0 (unsolved)

The AHS links are a little too complex for SG's code (positional hidden sets).
Not all that More...

MW-1 (sotir):
many other good possibilities exist after step 2, this may not be best, shortest
path I could find counting chaining steps.

1. UR(36)de.39::(8)e56=d5-d9=*(3)e8-de9=(43')bg9 # -8bg9.e8, -3d9

// xy: (1=6)i9-(6=5)i4-f4=f1-(5=1)e2-f1=g1 # -1g789.e9.i2

Hi Sarah,I am not saying h3=8.Just that the consequence of b3=9;OR f3=9 is the same;namely b7=8.

Best Regards,Alfred.

kobold, nice job on the 10/27 puzzle - not an obvious path imo! I struggled with it and gave up - a grid with a lot of possible chains most of which did nothing useful. I'd rather hit 'ice' quickly!
