Board texture: reading a flop before you bet it
A wet board demands bigger bets and real protection; a dry one lets you bet small and get believed. That single fact is (How much a board's suits and connectivity let hands improve, ranging from wet (draw-heavy) to dry (almost nothing beyond a made hand is live).), and reading it fast, before you pick a bet size, is the first step in almost every postflop decision, not an afterthought after the fact. Two flops that look similarly "random" can play completely differently: one where almost nothing beats top pair, and one where a flush or a straight is always live.
What makes a board wet or dry
A board's texture comes down to two things: what suits are showing, and how close together the ranks are.
- Suits: three cards of the same suit (monotone) puts a flush in play for anyone holding two of that suit, the wettest a board can be on suit alone. Two of a suit (two-tone) adds a real but narrower flush draw. All three different suits (rainbow) removes flushes from the picture entirely.
- Connectivity: ranks bunched close together open up straight draws in both directions. Ranks spread far apart, or a paired board with only one or two distinct ranks in play, close most of them off.
A wet board carries real draws: a lot of hands can improve, so bet sizing and continuation strategy need to account for that. A dry board rarely improves either player, so the decision tree stays simple.
