1. Note g5/i46=125.Unique possibilities to 29.
2. Whether d9=5;OR d5=5,g5=1;f7=1.UP31.
3. b5=48 to avoid the 48 Unresolvable Rectangle @ bh45.
4. b4=28 to avoid the 28 UR @ bf56.
5. Whether b6=8;OR b6=4=h5,h4=8;b4=2.UP81.

That is an efficient solution Bud. Note that your step 1) produces 2 extra UPs: h7=3 and i4=1.

Standard techniques UP 29
1. (5)g5=d5-(5=128)cdg9-(1)i9=i4 =>g5<>1 UP 30
2. (5)d9=d5-(5=12)g59-(1)g7=f7 =>d9<>1 UP 81

Or, alternative path using the same ALSs:
1. Kraken column (1)d954 =>SIS 5g5=1d5=5d9 =>d5<>5 UP 81
