Someone else may have responded by now but I think in speed chess it is a 5 minute game with 5 seconds for each player to make a move on their turn.
I’m also not to sure but what the chess depiction isn’t just another rabbit hole.
Rules of Speed Chess
“From 1990 through 1995 a group of roughly eight chess players, including myself and Willie Speaks, met regularly during breaks at work to play 5-minute speed chess. Lightning speed and keen competition made it necessary to develop a set of rules to settle disputes that occurred during the thousands of games that were played.”
