Do we really need to guess?

Postby Finlip » Tue Aug 01, 2006 1:13 pm

Many of the strategies that we talk about are ones where we look forward and see what the result will be if we put a certain value in a cell and when it doesn't work, we eliminate. So, I would like to assert that even if we guess, if we keep it in our mind and then eliminate a candidate without acutally typing one, we are not guessing. We either always guess or never guess.

There are educated guessing and uneducated guessing... What Finlip described is called "Nishio" guessing in Japan...:) And then there are also "superhuman guessing" e.g. no pencilmark, no notes, everything stays in the mind for puzzles like top1465 #77, #89 or Ocean's BB etc... I think Maria45, RW or Carcul could do this...:)
