Grouping games have been giving me all sorts of issues since I started studying and practicing them. It seems like the more I study and try to understand them, the more confused they become. I have studied the Powerscore methods as well as some of Steve Schwartz's stuff. The Powerscore methods seem overly complicated and sometimes it is difficult to keep track of all the conditional reasoning drawings going on during the games. Schwartz's stuff says not to do the Powerscore way and instead to do it his way, but he only explains his method in one or two very simple games and no more, so when questions arise on the more complicated games he doesn't explain, I am left holding the bag.

So my question to the board is does anybody recommend a service or something of that nature that they though had some easier way to explain the grouping games?
I am specifically running into issues with these games: PT36, G1; PT31, G2; PT35, G1
Any insight/help would be much appreciated!
Thanks
