Hi,
The Nightmare from 24 Mar can be used for a basic training in DIC - Double Impliation Chains.

Starting from:
Code:
........8
.1..843..
28..7....
.541.....
.7.....2.
.....541.
....9..31
..681..7.
5........

and you will get to the position:
Code:
4    369  379  269  5    1      27   69   8     
                                     **

69   1    79   269  8    4      3    5    27     
##

2    8    5    369  7    369    1    4    69     


369  5    4    1    236  236789 6789 689  3679     


1    7    39   3469 346  3689   689  2    5     


8    369  2    3679 36   5      4    1    3679     
       b        b                          a
       #        #                          *
7    4    8    5    9    26     26   3    1     


39   239  6    8    1    23     5    7    4     


5    23   1    3467 2346 2367   2689 689  269     

Here start with apha star from r1c8, follow BOTH digits and you will exclude digit 6 from r6c9.
Now start with apha star from r2c1, follow BOTH digits and you will
exclude digit 6 from r6c4.
Finally, start agin with apha star from r2c1, follow again BOTH digits and you will exclude 9 from r6c2 and this is breaking the puzzle.

have fun on the training,
see u
