While tracking down [r4c3]=9 from multiple Forcing Chains/Nets, I discovered a chain that I would never have detected otherwise.
- Code: Select all
[r4c3]=9=[r6c1]=5=[r5c1]-5-[r5c9]=(5=[r4c9]=6=[r4c8])=9=[r4c3]
Since my solver doesn't detect this type of chain directly, I was wondering if other solvers find this chain directly?
- Code: Select all
BTW: [r5c1]=3|4|5 => ... => [r4c3]=9
[r5c9]=3|5|8 => ... => [r4c3]=9
