Mechanics of Betting

Overview

Now that we know how to think in terms of ranges, it is time to apply that to our betting decisions. In this page we will discuss the motivations behind betting and introduce two practical heuristics: Range Advantage and Nut Advantage.

Why We Bet

Value-Betting

The primary purpose of betting is to win more chips with our strong hands. We call a bet a value bet if we believe our hand has more equity than our opponent’s calling range.

Bluffing

It is called a bluff when we bet with the intention of making our opponents fold a better hand. We bluff to win pots with weak hands that would usually lose at showdown.

It is called a semi-bluff when we bet with a draw. We can win the pot if our opponent folds, but we can also improve to a strong hand if our opponent calls.

Protection/Equity Denial

Sometimes we bet to deny our opponent equity. For example, if we bet a low pair and our opponent folds two overcards, they give up any chance of making a better hand. This is called a protection bet because we are protecting our vulnerable hands by making our opponents fold out equity.

Ranges and Betting

Betting is a tool to maximize EV with our entire range of hands. We must therefore consider both single-hand mechanics and how our strategy is shaped by our entire range. At a basic level, we can describe two kinds of range heuristics that influence betting: Range Advantage and Nut Advantage.

Range Advantage

Having a range advantage means a large portion of our range is stronger than a large portion of our opponent’s range. If we paired up our strongest hand to our opponent’s strongest hand, our second strongest to their second strongest and so on, we would find that our hands would win many of the matchups.

When we have a range advantage, we often want to push equity by betting a lot of our hands for a smaller size. This lets a large portion of our hands bet for value.

Nut Advantage

Having a nut advantage means we dominate the top end of the range versus range matchup.

When we have a nut advantage, we often want to bet bigger so we can maximize our winnings with our best hands and maximize folds with our bluffs.

Practical Takeaways

When betting, we should be thinking about both our hand and our range. We should be conscious about what our exact hand wants to do, but also how that fits into the story of our entire range. The next time you find yourself in a poker hand, ask yourself:

What does my range want to do here?

What about my exact hand?

Doing so will get you thinking about betting in the right way.
