I take it that you mean 79 in boxes 2 and 6 (by b(26)
and operating on the 9s in col 7(by SL 9 in c7) So if if there were no 9 at r9c7 you would have a strong link in 9 and your pincer and conclusions are OK but I don't see the WWing as is because of the lack of a strong link Yes it gives the solution but who has not stumbled on a solution bu got there by faulty logic!!!!!
Maybe I am the senile one |

Absolutely. I was careless to say the least. Never saw it. Thanks for pointing that out, George. |
