So apparently the people who play on cake poker are absolutely awful. Most of them are very tight passive, which is a little weird to get used to since people like that just don't stack off with TPTK. However, once you realize this, it's pretty easy to manipulate. Also, a lot of the awful players are regulars so note taking is very beneficial.
One of the ways I've been getting people to put money in when they are behind is to check behind the turn after cbetting the flop. I used to just continue firing the turn with marginal hands such as top pair weak kicker, but against many opponents I allow them a chance to bluff or call a value bet on the river. People who are weak tight are much more willing to call a river bet than they are a turn bet as there isn't a street of betting remaining. This is probably elementary for a lot of people, but I feel like I finally have gotten a good grasp of board textures to do so with.
Also, rakeback is still amazing. I'm at around $50 so far this month, with plenty of time left to scoop up more. Rakeback eases the pain of variance.
Edit: Here is an example of utterly awful play, which is far from uncommon.
