Today's game,after opponent's mistake I had checkmate in 9,
I am thinking and nonthing...
Have You Idea for this checkmate?

I only found mate in 7 :)

But I think, engine had only ~ 7 moves calculated, so, may be, there is, actually, mate in 9.

i don't agree with you tttttt
if you move rook on c7 instead c6 (move16)
Mate seems avoidable ( at least, could't find clear sequence with my little level)

can i delete my message lol
found a sequence in 2moves

Ok i put the donkey hat
