Any further thoughts:
He must click on my king during fog time after arena, and info "maphack indicator for iallwayslose" appeared on screen.
Right after I wrote about it at chat window, he !ignore me and wrote that I can report him. So, as he wished

We played till the end at 31 lvl, I wasn't able to send demon / kraken at 24, some kind of buttons freeze / delay.
Hacker anyway - look at his other demos can provide more evidence.
