So, I'd like to chip in. I'm not great at pysch warfare, but I can appreciate it. Esp in a competitive game.
However, there are a few things that cross the line. Recently, there have been some new core set era newbies coming to play Xwing with us.
They literally chatter non-stop, for 75 whole minutes. To themselves. Saying, "I should have done this move and I would have totally destroyed your ship." (No, you have a 25% statistical chance of rolling those hits and I have a 85% of rolling at least one evade). "Or narrating everything, "Okay, now you're shooting me, and I'm shooting you. And nex tturn you'll be on the rock. (didnt happen again, I out maneuvered him.)
I still beat him anyways. While he literally talked to himself. Because in all of his talk, he never actually left any space for anyone else to jump in.
After the game I really just wanted to leave cuz he was being literally annoying.

Also, if you try psych warfare in a casual game against a person you don't know, that's extremely rude imo, and you are likely making a strong enemy.
This is a game. Your worst enemies aren't the ones who will beat you. They're the ones who will refuse to play with you and tell their friends also about the negative experience they had playing you.
What you describe is not psychological warfare, but just a person who annoys you.
I understand. That would annoy me as well. I certainly don't engage in this behavior *cough*mostofthetime*cough* myself.
