3. you take 2 minutes to play f5
1000 reasons you lost a game
(1) You resign on move 3 because you're a 450-rating player who really can't face yet another fried liver gambit.
(2) You resign on move 10 because your opponent hasn't yet moved a piece, and you really loathe endless pawn-pushing games (and being 450-rating, always lose them anyway)
(3) Your opponent seems a decent person who's played a really good game until about move 25, when they blundered their queen. You felt so bad you offered a draw, they took three minutes to refuse, and you found you'd lost on time. This may be one of the reasons you're a 450 player who gazes up at the dizzy heights of 600-ratings with envy.
(4) You had a winning position but thought you'd lost it, so you resigned. 450-rated players don't spot winning positions very well.
(5) You're a 450-rated player who's obsessed with playing better chess and you resigned out of frustration to punish yourself for making a silly mistake that quite probably wouldn't have cost you the game.
(6) You're a 450-rated player and therefore don't play great chess.
(I'll think of the other 994 later, but I write from experience, as a 450-rated player)
1 your opponent hacks the 30 min game so you get only 1 min
2 your dog barks at you so much that you forget how to play chess
