UPs: b8=4,f2=4,b6=2.Pairs 78 at ab5;pairs 89 at h6,i4.A forced chain starting with b4=9 leads to a contradiction,hence b4=5,a6=9,h6=8,i4=9,c6=1,c4=4,d6=4,h7=3, f6=5,h8=9,d7=9.If h3=6,e5=6,a2=6 and no 6 in top left box, hence h3=7.Pairs 16 at ae8 and 25 at di8.Whether d8= 2 or 5, h9=4, and the rest are unique possibilities.
