ER on 3 => r1c9 is not 3
5-SIS AIC : 9B3 9C6 1R7 (13)R8C9 3C3 => r1c7 is not 3
Kite on 1 => r9c6 is not 1

[edit]I have problem editing the brackets !? Pfff... So I added Kite(1) that disappeared in the edition of the solution. I also corrected Sky(3) into ER(3) in the 1st move and 9B9 into 9B3 in the 2nd! Pfff... Sorry, for the confusion.

Besides 2x extraneous turbot steps on <1> & <6>, 3x complementary steps that added Locked Candidate 1 to VH steps.

Code:

c3b3 Empty Rectangle <> 3 r8c8 complementary
c3b9 Empty Rectangle <> 3 r1c9 Locked Candidate 1

c24r7 Skyscraper <> 5 r1c5,r3c1 complementary
r18c5 Skyscraper <> 5 r3c1,r7c2

c1b8 Empty Rectangle <> 1 r3c6 complementary
r1c1 2-String Kite <> 1 r9c5 Locked Candidate 1

<69+3> XYZ-Wing r3c6/r2c6+r3c8 <> 3 r3c4

<13+6> XY-Wing r9c1/r2c1+r9c6 <> 6 r2c6 complementary
<16+3> XY-Wing r9c6/r2c6+r9c1 <> 3 r2c1 Locked Candidate 1

BUG+1 = 9 r3c5

I used to have tons of problems here w/editing and cutnpasting. Solution for me was checking Disable HTML in this post.
