17:23 mAen! Another beautiful city I haven't visited...

1. Unique possibilities to 28.Note pair 16 at e79;triple 348 at fgh9.
2. If f9=4,i2=4 and row 8 is devoid of 4.So f9=3.UPs to 37.
3. If h3=8,g3=7,g6=2,e6=4,a4=134 (to avoid the 58 rectangle at ai46),e2=3,f2=7,e3=9,e8=4,d8=5 and row 3 is devoid of 5.Hence h3=7.UPs to 48.
4. If b3=3,g1=3,g3=1,d3=5,d8=4,f8=7=e2 and row 3 is devoid of 3.So a2=3.UPs to 81.

29:10, all. We went there nearly 20 years ago, caught the train from Como so we didn't have to drive in Florence!

1) Start at 23,basic techniques to UP=28
2)(4):i2=i8-d8=d1,=>f2<>4.UP=38
3)(3)a2=e2-(3=9)e1-(9=8)c1-f1=(8-7)f2=(7)e2,=>e2 <>3.UP=81

step 3 more trenchantly:
3. (3=9)e1-(9=358)ac2,c1 => ~(3)e2.

using Alfred's style:
3. if e1=9 -> a2=3 (naked triple 358 in ac2c1) or e1=3. hence e2<>3.
