I mean, that’s kinda how it works when playing 1 on 1 with no audience and one player misses moving into check, and the opponent misses too.
And there’s plenty of people that play with no check at all. You don’t have to announce it, it’s on the player to detect and counter.
I prefer check being absent in casual, friendly games unless they’re so friendly that you’re also notifying the other player of missed opportunities or mistakes. Which is, imo, the optimum way to play with friends that aren’t at the same skill level, or are very closely matched to the point that the game is going to drag on when there’s limited time to play.
Yup, and likely not the recent past, say ten years plus
