Is it +EV to bet the river? I don't know if a hand worse than mine would call. In this session I won alot of hands on the flop and turn. This was my most successful session since my return. The table was very passive and I was able to get free cards when I needed them. What I was doing was not really loosening up more, but playing my hands more aggressive. If I got KQ UTG I was raising. If I had top pair I was firing away and raising, etc.

I will usually bet the flop and heads-up on the turn I'll almost always fire a barrel.

On the river you should check behind. In general, if someone gets there with fourth pair, they're going to call so you're not making a better hand fold usually (although you will very occasionally) and it's very unlikely a worse hand is calling. Take your free showdown, that's what position is there for.
