Basically yomi / hard call out. Everybody knows chess.
A lot of the time when I'm playing someone I kind of have a mental flowchart going through my head of what I think they're going to do, what I'm going to do to counter it, what their response is going to be, and what my response to that will be, until I reach the "solution" where I win. Usually against my brother who plays Tager it goes something like: I knock him down, I go for Hotaru on wakeup, he goes wakeup MTW, (I saw it coming) Hotaru clashes, I go directly into j.D to avoid getting destroyed, he rapid cancels and goes for mixup, and then one of us will win the exchange based on what I thought. But if I made the right move then that's what I meant by checkmate. Technically it's more of a general thing.
Should've just called it a call out. :3 The reason I made the chess analogy though is you don't want to just do it all over the place randomly, you want to do it only after you thought it through and know what they're about to do, in a deliberate way.
