Poker is a game where you have to play against some people. It's also a complex game that doesn't end before flop or on flop all the time. There is 3 streets to play after pre-flop. You should always have some sort of a small plan for every card that comes up.
What cards will you cbet? When will you check/fold flop or check/call (check/raise)?
How does some card affect your range?
How does it affect your villains (perceived) range?
What is your perceived range and does that card hit it well?
And so on. Always have a plan.
