Surprisingly short XY-Chain
(2=4)r7c2-(4=1)r7c5-(1=6)r1c5-(6=2)r1c3=> -2 r2c2,r9c3 |

Hi everyone,
another possible XY-Chain for number 6:
r2c2 - r7c2 - r7c5 - r1c5 - r1c3 - r9c3 - r6c3 and -6 in r1c3, r456c2.
Ciao Gianni. |

Another one:
(2)r9c6 = r9c3 - (2=6)r1c3 - r1c5 = (6-4)r5c5 = (4)r5c6 => -2 r5c6; stte |
