I think a good push fold chart/ nash GTO chart/ whatever the kids are calling it is all you really need. 20 BB poker isn't rocket science.
That being said, I'm vehemently opposed to shit like these hyper turbo HU spin n go jackpots. PS has, at least since Amaya, been doing everything they can to reduce the edge in poker on their site. It's all designed to let the fish lose slower, thus generate more rake. Spin n Gos, no HU cash tables, no deep stacked tables, etc. I'm shocked they haven't blocked HUDS.
