Or trick your opponent into thinking you have the out when you don't, so they fear over committing their resources. In tournament settings, stress and emotions run high and it's important to be able to play confidently even when you are most likely to lose. Even in Hearthstone with how limited interactions there are, you can still find a way to communicate false information to your opponent. As world champion Firebat recently said in a video: "if you play enough you aquire the ability to know what your opponent has in their hand based on small hesitations...how long it takes their eyes to register things". Edit: I guess since we are looking for parallels in life the takeaway is this, maintain confidence and self-awareness especially when losing, and always consider how you present information to others. You can reframe most things to appear better without being deceptive.
