It's not PRIMARY. But, if youve ever played competitive sports, there is always some sort of chess match happening to try and get a little advantage. When you can "guess" accordingly it can be an advantage at an opportune time.
Remember Jordans last game for the Bulls? Scored to tie game, then when Karl Malone who had it on the block for probably 95% odds of taking back the lead. But Jordan snuck behind him and stripped him and stole it before his scoring move began Jordan goes back down and drains the game winner. Bulls win title #6.
That steal was exactly one of those tendency moments. Just a popular example that came to mind.
