I had a logical reason to believe the position was not a Mate in 18.
I did Shredder analysis to verify.
 Depth: 32/66   01:07:20  2431231kN, tb=49150885
After tb access of over 49 million times it did not find a Mate.
I Posted the analysis & my opinion. That is my right.
I did not argue I was not abusive.
I think it is abusive for a Mod to personally attack a Poster.
