Can be games where you were down 20 seconds in and won on time. Games you & the opponent had 5 seconds in and you barely won.
Last-second or accidental checkmates. Games where you somehow came back down a bunch of material.
Games full of misses and mistakes and both players had plenty of chances to win, or games played incredibly by both sides that came down to the wire.
The only requirement is that they must be chaotic, also please don't harass each other if there is a bad performance everyone has one at some point
