Post-Flop - Tricky Players

[imashyboi]

Hi, I've been thinking about this for sometime. Can someone give me a few example about tricky players? What do you exactly consider as a tricky play after the flop. When playing on Party, you'll encounter alot of players who's playing style is very different. How do you seperate a tricky player from a bad player, they both play almost alike but the a bad player just play looser preflop.

Thoughts?
