A few more points.
NEVER argue about rules...if a disagreement on a listed rule happens, ask the other team to show you the ruling. If they don't. You are the correct one. If they show it and the interpretation is disagreed. Get a ruling from the rep or a trusted 3rd party.
Matches are 3 points split. 3 for a shutout, 2 for a win, 1 for a sudden death loss ("hill hill loss"). Something I don't know if more people realize but playing a 2vs2 or a 3vs3 automatically ensures the teams will SPLIT 3 points per match instead of the chance of a 2-0 match
if you think your best player might get creamed...play your worst instead. Teach your players to take this match VERY seriously, and remind them if they get any games it's a HUGE win for the team. Even when they lose its a huge win, because now your best can play their 2nd best and win (more likely anyway). For example if they are playing 76532 and you're playing 66542, if their 7 is a "super seven" (who has like an 70%+ win ratio) playing "even" is a losing move.
Instead you can play your 2 against 7 and have each of your players have a 1 skill edge in their matches (higher skills do best lower ones more often, even if there is an equalizer)
I always coach my players, it's how they learn, if they have 2 coaches and are at least halfway through their balls and a tricky butnimportant situation comes up (like the differences between scratching versus making an easy 3 balls) CALL the coach, they probably don't know they need one. Save your second coaching for a desperate kick, a really scratchy 8 possibly loss, or an important position onto the 8 etc
Before the match write up all possible "max skill lines". I do all lines that add to 22 or 23. figure out which players are common on several lines. Like if you have only the lines 75443 and 65444, you know the 4's and 5 will play either way. If you throw them in matches 1, 2, and 3, you still have options of lines and your nopponent can't predict what you'll play
His uncertainty may lead to a mistake in matching up effectively
The same logic allows you to predict their lines and cross off lines no longer possible, sometimes thinkers you known by match 2 or 3 (sometimes even match 1) exactly what they can play
really good players in a skill level are great against both 1 skill level down (good chance of shutout) or 1 skill up (good chance for a non shutout win, against a "better" player at that)
a really good 4 is super stressful for a 7 to play, 1 game alone earns a point, 2 is a WIN! If the 7 is low end, and the 4 is good, it's a really great value match (and you gain 3 skill in difference that you can spread across 3 players for 3 advantage matches, as I said higher skills do win more often against low)
play drinkers early, or ask them to be slow drinking before their match
Play nervous players first when the pressure of winning it all or losing it all comes down to them in the last match
there are some ultra simple but key shots, that low players repeatedly will be unsure of like a hanging ball in a pocket and not scratching (straight in), or getting easy position off ball in hand etc, make sure they always use SOME angle
Show them 2 way shots, if 2 options are equally likely to go in, show them how to know when one miss would sell out the game whereas the other might play safe or leave a difficult shot, 2 way shots are the best way to play strategically while keeping skill levels lower (totally ethical)
ALWAYS mark defensives, especially for the other team, if they don't call safety but they "did not try to make the ball" mark it, teach your players to call defensives before they prepare to shoot, not after, as you might want to coach them to shoot offense instead (or vice versa if a clear defense is available)
