Certainly feel free to ask questions about the DDSCB2018 here in the forums. There are a lot of people who have played DDSCB for quite a while. They and those who recently have begun playing DDSCB are likely to have some ideas that may help you.
BUT...also there is a "QUICK GUIDE" available by selecting "HELP" on the game screen. Then click on the BOOK icon on the left side of the resulting Help screen. That will open a pdf containing the Quick Guide. The guide is meant to provide basic guidance to help players with the various components of DDSCB2018 as they progress through the game. It is NOT a detailed manual on all nuances of the game and doesn't get into strategy guidance.
One of the beauties of this game is that you can play it so many different ways, and people evolve their own strategies and game play techniques as they continue to play the game.
Try out the different parts of DDSCB2018 including Exhibition Games, Tournament Maker (i've loved this one since it came out with DDSCB2017), Importing an association from DDSCB2017 (brand new with DDSCB2018), a multiplayer game (you can run multiplayer by yourself if you want to have more than one coach you can control). And don't forget there is a Restore Association Backup if something catastrophic ever goes wrong with one of your associations.
