This has bit me in the butt twice in the last few months. Game is going on, you know going in that it will be "interesting" as the game has meaning (one was a mens semi-final, one a preview of a state cup final) As the game starts, its going fine, good game, fast paced, players playing, you've identified the play makers and flow and strategy. Then it starts: - you make a call that someone doesn't like, so they chirp about it, nothing real, not dissent, just a quiet comment or question. You work with the person, they don't debate, they take the answer and move along. Fast forward to well into the second half. Somehow, you've gone from that player just making a quiet comment to being across the dissent line. The issue I have is somehow, we got here VERY slowly and gradually. If the player had done earlier, what he's doing now, there would have clearly been a dissent card, he earned it. My issue is "How the heck did I get here?" The player ramped this up over the match very slowly and I fall into the trap of "I didn't card the last one, and this is almost the same....." I know that I have dealt with this by just pulling the card and basically saying it's for the accumulation of comments, not any one comment, but I've had enough and that has worked. I guess what I'm looking for here is two things: 1) How do you detect this is happening to you before you're to far down the road? 2) How do you deal with it as its progressing?
