A Twist on Kraken X-Wing

Postby daj95376 » Sun Nov 12, 2006 4:38 am

How about a Kraken X-Wing where the X-Wing needs assistance!
(Yes, I know this isn't reasonable, but it sure was a lot of fun!)

Code: Select all
.....3..563.5.4.9...1.6...4......4123.......7142......5...9.7...9.4.5.834..8..... # D 021

# after SSTS
# X-Wing [r79C29] in <1> with fin cell [r2c9]
 *--------------------------------------------------------------------*
 | 2789   278    4      | 1279   1278   3      | 268-1  267    5      |
 | 6      3      78     | 5      278-1  4      | 128    9     #18     |
 | 2789   5      1      | 279    6      2789   | 238    237    4      |
 |----------------------+----------------------+----------------------|
 | 78     678    59     | 369    358    689    | 4      1      2      |
 | 3      68     59     | 12     4      12     | 5689   56     7      |
 | 1      4      2      | 679    578    6789   | 35689  356    689    |
 |----------------------+----------------------+----------------------|
 | 5     *128    368    | 1236   9      126    | 7      4     *16     |
 | 27     9      67     | 4      127    5      | 126    8      3      |
 | 4     *127    367    | 8      1237   1267   | 12569  256   *169    |
 *--------------------------------------------------------------------*

fin cell  [r2c9]=1 =>             [r 2c5]<>1 &              [r1c7]<>1
X-Wing             => [r8c5]=1 => [r12c5]<>1 => [r1c4]=1 => [r1c7]<>1

Mike Barker: I know that I promised to look for less complicated fish, but I couldn't help myself.

Note: A single-digit Implication Chain (sdIC) on <1> in [r8] will produce the same eliminations.

Well, maybe you should look for the less complicated, there's a normal finned X-wing that does the same:
Code: Select all
 *--------------------------------------------------------------------*
 | 2789   278    4      | 1279   1278   3      | 268-1  267    5      |
 | 6      3      78     | 5     *1278   4      |*128    9     #18     |
 | 2789   5      1      | 279    6      2789   | 238    237    4      |
 |----------------------+----------------------+----------------------|
 | 78     678    59     | 369    358    689    | 4      1      2      |
 | 3      68     59     | 12     4      12     | 5689   56     7      |
 | 1      4      2      | 679    578    6789   | 35689  356    689    |
 |----------------------+----------------------+----------------------|
 | 5      128    368    | 1236   9      126    | 7      4      16     |
 | 27     9      67     | 4     *127    5      |*126    8      3      |
 | 4      127    367    | 8      1237   1267   | 12569  256    169    |
 *--------------------------------------------------------------------*

The '1' in r2c5 is then eliminated by locked candidates.

Btw. Wouldn't a post like this fit the 'Ultimate fish guide' thread better than the 'general' section of the forum?

RW, you're right about the finned X-Wing (eventually) performing the same eliminations. I didn't catch that. Instead, I was looking for a way to perform both eliminations at once, and stumbled onto this wild interpretation.

Does everything in life have to be serious? I indicated in my post that this interpretation wasn't reasonable and was for fun. That's why I posted it in the General section of the forum so it wouldn't impact the serious work being done under the Ultimate FISH thread.

Interesting puzzle:

Code: Select all
 *------------------------------------------------------------*
 | 2789   278    4   | 1279   1278   3    | 1268   267    5   |
 | 6      3      78  | 5      1278   4    | 128    9      18  |
 | 2789   5      1   | 279    6      2789 | 238    237    4   |
 |-------------------+--------------------+-------------------|
 | 78     678    59  | 369    358    689  | 4      1      2   |
 | 3      68     59  | 12     4      12   | 5689   56     7   |
 | 1      4      2   | 679    578    6789 | 35689  356    689 |
 |-------------------+--------------------+-------------------|
 | 5      128    368 | 1236   9      126  | 7      4      16  |
 | 27     9      67  | 4      127    5    | 126    8      3   |
 | 4      127    367 | 8      1237   1267 | 12569  256    169 |
 *------------------------------------------------------------*

1. [r7c3]=8=[r7c2]=1=[r7c9]-1-[r2c9]-8-[r2c3]=8=[r7c3], => r7c3=8.
2. [r1c2]-8-[r5c2]=8=[r5c7]-8-[r3c7]=8=[r3c1]-8-[r1c2], => r1c2<>8.
