bad players are tuff to get any read on especially the alliners....but paitence until you get a hand you;re willing to go to the mat with can win out over a bad player ... in tournaments there are many many more so again paitence is key , let the donks knock each other out until you can get into HU situations with strong cards , even if they have many times you're chip stack you can chop em down...... in poker playing the odds will get you further than relying on luck
Now the other side of that is the Good playa's , they make good opponents & the really good ones will mix things up on what cards they are willing to play or raise with so you need to be a bit fearless & know hand strengths , draw odds etc to call & be competitive
