It is a summary after reading articles from this forum. For self rated: Don't beat your opponents too bad, play left hand if you are righty. Let them get 5,6 games to avoid getting DQed until National. No DQ in National. For B,C rated: If you are OK to be bumped up at end of year, just play your best in all matches. If you don't want to be bumped up, it is OK to play your best in the beginning of the season since ntrp rating depends more upon the last couple of matches. Need to tank at the end of season, e.g. have close game in region/playoff/sectional/national. Especially having a close game against low ntrp rating player is very helpful.
