This is a Connect-4 move, which involves the Other Player sub-consciouly surrendering to the Player by letting them get 4 horizontal tokens in a row. This move is distinct from the Norwegian Pincer due to their only being one valid spot to place the winning token. Meaning that it is entirely possible for the Other Player to block it.
