Is my oppenent cheating?

Interesting question, I myself tried to report many many cheaters and got experienced in that( so I was even limited to do that xD) but that case seems like more humanwise, I don't see here much of computer pressing and " no way to breathe" it's just luck+ some casual positional realization with few advantage

Please don't public shame, as per lichess.org/page/forum-etiquette

If you think that your opponent was cheating, use lichess.org/report instead.

@AtomicChessSensei OK I have deleted the game
