There is a specific kind of player that uses all caps when typing: The professor type

. You know, the guy that just can't help but tell you that you were "drawing slim to none ... and Slim is out of town." These non-objective players 'shout' by putting everything in capitals ... which is annoying.
I have a policy playing online that anyone that is even marginally annoying, I mute their chat

... it solves a lot of problems, eliminates the distraction, but I do put in their notes "professor type" because these kind of players play a subset of hands that are very predictable, and in Pot Limit Omaha, are a literal river of money when your odd hand hits the flop hard in an unlikely way. Since by definition they are locked into their professorial view of the poker universe ...

... they will never put you and that hand and the payoff is huge ... hehehe ... and they tilt like the Tower of Pisa.
