Hi Mathman From Tigerland - re your question yesterday.
I can think of two reasons for not being required to prove uniqueness when solving.

1. Note pair 38 at e2/f1. Unique possibilities: e8=1=h2,d9=7=f6,e3=9 (UP27).
2. Locked 2s at ai59;so pair 38 at e25 make e7=4=f4,f5=5=d3,f3=1. (UP 32).
3. When a2=5,a8=6=i1,g1=5. When a2=9,g1=9,a5=2,i5=3. So g1/i1 are never 3; This makes f1=3, and the rest is solved (UP 81).
