I played an offline game with a friend (Botsrequired) today.
The gameplay wasn't planned, as it was an unplanned visit. He's slightly ill, so I didn't go along with my board.
We randomly decided to play a friendly, offline match using the chess.com android app.
I played as Black, so in the video, I'm identified as 'Guest', since we played on his smartphone.
I lost today's game. Maybe I decided to go soft on him. Just, maybe.
I made a terrible blunder at the 00:42 timestamp. I played Bishop to B4.
I simply lost interest and played passively, no longer taking it seriously. I resigned at that point. But for the sake of gameplay, I simply continued without interest. It was a friendly game, so I didn't worry whether I won or lost.
For the record, I beat him 70% of the time. I wasn't simply in my comfort zone today due to the rotating view whenever it was a player's turn.
It was my first time playing on a screen that small, and on a rotating view. While I normally play on the board and online, via my PC, it was the first time I would be playing on a shared smartphone screen, as it was an offline game.
It confirms my theory that a slight change in perception can alter the gameplay experience.
Observation
I play terribly as black. I make blunders I wouldn't make when playing as white. More reasons I should play more as black. Regardless, Bishop B4 was a terrible move in that case.
The gameplay
Time control: Unlimited.
