The second rule of fight club is (you ready for this? OK then.) DON'T BE A D***! Seriously, this will make everything rainbows and unicorns. You can trust me. I'm old. Play by intent! What that means is: explain to your opponent how you would like the game to go. Hey, if you tell me you want to have this unit out of sight, then help your opponent and make sure you both agree that his unit cannot be seen and then move on with your life. Having a "gotcha moment" in the middle of a turn is just a horrible feeling for either player and is not how you want to win or lose the match. You will win more consistently and have a more relaxing game by playing intent and not having to worry about a technicality losing you the game. Equally crappy is winning that way. Don't do it.

The third rule is to know your opponent's list. When you come up to the table, take a few moments to review your opponent's list, and don't be afraid to ask questions about units, wargear, or abilities you aren't familiar with. A few moments pre-game will save you a headache of rules debates or a crushing defeat to your well-laid plans. Make sure you know which of your opponent’s beautifully crafted models have which upgrades and which squads are which. The realization of "oh, that squad has the Master Crafted Thunder Hammer" is something you don't want to find out turn six when you thought you had the game in the bag. It feels terrible. Don't do it.
