Similar to Ted but UR instead of BUG...
Quote: | w-wing(67) (7=6)r1c5 - r1c8=r6c8 - (6=7)r6c6 ; r4c5<>7, r3c6<>7
(7=6)r1c5 - (6=5)r8c5 - ur(17)r37c45[(5)r7c5=qnp(68)r3c56] - (6=7)r3c7 ; r1c8<>7 |

Peter: I would have seen your chain in terms of a common UR Type ...
Quote: | (7=6)r1c5 - (6=5)r8c5 - (5)r7c5=ur3(17)r37c45 - (6=7)r3c7 ; r1c8<>7 .
