A path for this one:

1) Start at 23,=>UP=27

2)Coloring (4):c4=g4-g8=h7,=>c7<>4

3)fc:(8)b13=(8-5)b4=(5-4)c4=(4-9)c8=(9)b8=(9)b8,
==>b13<& gt;9, UP=28

4)fc:(8=3)b1-(3=1)b5-(1)i5=(1-8)g6=(8)a6-(8=5)b4,
==>b4<>8, UP=81

1) Start at 23 filled, the given puzzle. Unique Possibilities (UP) to 27.
2a) np13 at b5c6, => a56<>13
2b) fc on 3's: e1=e6-c6=b5, => b1<>3.
2c) fc on 4's: c4=g4-h5=h7, => e7<>4.
2d) (8)a6 = (8)b4 - (8=9)b1 - (9)b8 = (9-4)c8 = (4)c4 - (4=6)a5, => a6<>6. UP 81
