The flop — the first three cards
The flop is when three community cards are revealed at once, right after the preflop round. It's the moment with the biggest single jump in new information: from 2 cards to calculate with, suddenly there are 5. Typical strategy starts with reading board texture (wet vs. dry, connected vs. scattered) and deciding whether to continue aggressively with a c-bet — a continuation bet from the preflop aggressor. These decisions lean directly on the ranges from the preflop chart.
