Need help further reducing naked pair

Postby Gimpy » Thu Sep 22, 2005 8:10 pm

Here is the puzzle so far

38* *** 92*
*** 439 785
**9 *2* 3**
*6* *9* ***
8** 3*2 **9
9** *4* *7*
**1 97* 5*8
495 286 137
**8 *** *92

There is a 1-5 naked pair in Bottom row (r9?) in Middle box at the middle and left (c4-c5?). This leaves the other two options in this square to be 3 or 4 but I cannot figure out which one could be eliminated from there.

Hi Gimpy,

I'm not sure, but I think it's too early to tell.
I suggest leaving both 3 and 4 as candidates in
r9c6, and looking elsewhere for more patterns.

There's a naked triple in row 2 box 1 and a naked pair in column 3 that will let you place the 6 in box 1 and start you eliminating other candidates.
