Tough of the day:
Standard techniques UP 27
1. (9)a5=(9-4)g5=g6-(4=7)b6 =>-7a5 UP 29
2. (1)a9=c78-c3=(1-367)e237=(6)f9 =>-1f9
3. (2)f6=f5-(2=8)i5-(8=9)a5-a4=(9-5)h4=(5-1)i4=(1)de4 =>-1f6 UP 38
4. (3=5)g3-(5=7)h3-hi1=(7-3)b1=(3)b2 =>-3g2
5. (4)c5=(4-9)g5=g7-(9=4)h7-e7=(4)e2 =>-4c2 UP 81

Hi cenoman. After your step 1, a5=89, how do you get two more UPs to reach UP29 ?

Best regards, Alfred.

Hi Alfred,
at step 1, after -7a5, you get d5=7 (hidden single in row 5) and subsequently d2=2 (hidden single in column d).
Best regards.

Hi again cenoman. Sorry, I still can't see it. Why can't c5 still =7 ?

Hi Alfred,
I guess you have missed some elimination while processing standard techniques...
No 7@c5 because of a naked triple (127)@c237...

Here is a possible sequence:
Naked single b3=8
Hidden single b7=9
Hidden single f2=9
Locked set (2)@c23 in block 1 More...

Thanks, cenoman.I missed the triple 127 in column c.
(BTW,your notation is not always 1-9 from bottom to top, but I still could follow it.)

Best regards, Alfred.
