What makes a good 4th and 5th street player?

[StLouisMike]

It seems to be that most losing players aren't good post flop players. They have trouble when the the scare cards come on the later rounds and even more when they come in with a reraise from their opponents. My question is what skills make a good post flop player? What can a player do to find themselves in alot of murky situations on the turn or river? I would assume that hand reading, position, and effectively reading the board (ex. You: AQo Board: Qd Td 9s, would be considered a marginal hand due to the diamond and connected board Vs You: AQ Board: Qd 6s 2c is a strong hand due to no flush or str8 draws likely) are paramount to bieng a good player in later rounds. Thanks for the replies in advance.
