OK, I take your word for it. The truth is that SE doesn't work at all on my computer, so I had to work it out by hand, rather unsure of exactly what "Direct Pointing" meant.

(I downloaded the .zip, extracted the files, tried to open it and I got a message that says:

Java Virtual Machine Launcher wrote:Java Virtual Machine Launcher

Could not find the main class. Program will exit.

What am I to do?)

You can launch it directly as a JAVA applet from the site itself.

If you want todownload it, the donload & run the package which has the JAR file

But trying to open the .jar gives exactly the same infuriating message as the .zip and trying to open it as a Java applet gives a message in the launch area saying "The application has been launched (You may need to wait a few seconds) " and a message at the bottom of the screen saying
"load: class diuf.sudoku.applet.SudokuApplet not found"
and absolutely nothing loads.

hey 999_Springs,

"Direct Pointing" and "Direct Claiming"
are discussed (rather off-topic) at
"A collection of direct hidden pairs according to SE"



also there, i gave a 46-clue example (2008.Jan.20) of 2.0 ("Direct Hidden Pair") --

Code: Select all
 1 9 8 | 5 6 3 | 4 7 2
 . 4 2 | 9 . 8 | . . 5
 . . . | 4 . 2 | . 9 8

 8 . . | . . . | 2 . 9

-------+-------+------
 4 2 . | 8 . . | 9 5 6
 6 8 . | . 9 . | . 2 .
 9 . . | 6 2 . | . 8 .

I found this lurking on my desk in a dark corner. It has probably been there for about 2 years. (Oh, the strange things you find hidden in desks...)

(this probably could be improved)
