I did not resign.

why would I?

here it is. my move Check out this #chess game: mono25 vs Facetious_Jackson - http://www.chess.com/livechess/game?id=1292809332

Your opponent resigned. Thats why it says you won by resignation as they left their queen hanging

"Facetious_Jackson won by resignation"

Your opponent resigned.  You won the game.

It may sound like a stupid way to word the sentence / unnecessary use of the passive voice at first, but chess.com decided to make the name of the winning player consistently first, e.g. Facetious_Jackson won on time, Facetious_Jackson won by checkmate, etc.

Resigning is not technically something you need to do when it is your move only. On occasion, your opponent will make a move with the realization that you have x-number of winning moves or a move that exploits their last move and resign before you make that move.

My mistake, thanks for clearing that up.
