Get gold, watch lessthantreee's video on how to use HEM filters. He only explains basic ideas but if you use your imagination can you possibly find all your leaks.
TBH you don't even need that video, anyone who has a clue on poker can figure that themselves. Just play with the filters and you'll see.
Or if you wanna analyze a specific game hand by hand, use the implemented SNG Wizard and hands equity tool in HEM. Really helps a lot.
Sorry for a useless post if you do that already. Anyway what could be a better way to review your games.
