Sudoku Puzzles

I hoped to blog this one, but could not find the time. I hope no one minds that I peeked ahead. Here is a possible path:

1)UP26, Locked (4)g45=>g79<>4
2)(2fxw): b4=b3-f3=f45 => e4<>2
3)Let A be a two string kite-like Boolean. A: [(3): More...

What a lovely photo!

Enjoy your day, everyone!

26:03 mAen! One guess... a good one! Lovely picture there... must be a rather parklike part of Rome!

tough >1.5 hrs

1. Unique possibilities;c9=5,h6=2,i1=6. (UP 26)
2. If g9=8,b9=6=a2.Likewise,g9=3=i3=f4=a6=b2 makes a2=6.(UP 27).
3. If g9=3=i3=b2=f4=a6,c1=2 (to avoid the 23 rectangle at de17),b4=2,a4=1=i6,c6=8,c5=6,c7=4,i4=5 and 45 have no place in top right box.So g9=8 and UPs to 81.

Really tough - took me 2 hours to solve

SE=9.0

Steve's 'kite-like' boolean must be somewhere else (typos)
kraken loop column(3)f > -6e9 -4ac6df5ef4 -3e4
(3)f4*-(34=6)e6}
||
[(3)f9*=f23*-de1=g1-i3=i7]
|
(23=6)e6}
(2)d7=(2-6)e7=f9-(6=2)f5 > -2d5, UP29
(7=4)a9-c7=c5-(26')cf5=(6)f9 > -7f9, UP81

note:used short AIC loop before kraken to clear the weeds.
