A horse is a horse of course of course, but look at that set of tonsils!

Hi all.
I reached 32, and managed to eliminate a couple of candidates by fc. But what is the next move? I cannot find an fc that helps.

A legitimate tough one today:

1) Start 22, Unique Possibilities to (UP) 27.
2) Hidden pair 36 at be4 forbids b4=479, e4=1479. UP 32.
3) Locked 8s at ef9 forbid hi9=8.
4) b4=6 == e4=6 -- e7=6 == a7=6 forbids a6=6, b8=6.
5) i3=1 -- i3=8 == i8=8 -- i8=5 and i3=1 -- g1=1 == g1=5 -- More...

Sweet dreams, Tori.

Hi Clark.I'm not too sure about your #8 as I still have c2=6? Have I missed something somewhere?

Disregard this. It's just a test.

You didn't miss anything, I did. Here is an updated proof:

1) Start 22, Unique Possibilities to (UP) 27.
2) Hidden pair 36 at be4 forbids b4=479, e4=1479. UP 32.
3) Locked 8s at ef9 forbid hi9=8.
4) b4=6 == e4=6 -- e7=6 == a7=6 forbids a6=6, b8=6.
5) i3=1 -- i3=8 == i8=8 -- More...

10:48 with 3 guesses, educated ones of course!

testing 123

testing 456

another possible proof (without angle brackets!)

1) Start with 22
2) UP 27
3) NakedTriple: ghi4=179 => ~bef4=79
4) UP 32
5) Locked: def9=8 => ~hi9=8
6) Locked: abc2=9 => ~f2=9
7) Simple Coloring on 6: => ~b8=6
or (d8=6 == e7=6 -- e4=6 == b4=6)
8) d8=6 More...

I had to use a guess to get it, then it all fell into place easily. For those of you who seem to have no trouble in solving these tough puzzles, do you always know that the number you are putting in is absolutely correct? When I do them on paper, I have a system that tries out numbers (if this is More...

belay that last transmission, got garbled
(i was trying to use angle brackets and forgot that
xml takes a proprietary view of them).

here then is a proof (depth 5 or more - sigh)

1) Start with 22, UP 27
2) Naked Triple: ghi4=179 => ~bef4=79, UP 32
3) Locked: def9=8 More...

Hi all,
i see in tough, someone write 10:48, 6:15 ... that mean they can solve 6-15 minute? Wow... i need 1-2 hours everyday. why? because i need a lot of time for think about which number can start best after unique possibilitis. today i start with fc on 6's ... can you tell me strategy which number for start? thanks. Oh, horse is seem angry. Sorry for my englisgh no good.

Named after Tori Spelling I presume - my caption would read - 'hey anyone out there! I'm locked up here I cant get out - Hey ANYONE!'
