A block bet is a relatively small bet, typically ranging from 20% to 40% of the pot, made by a poker player out of position. Its primary purpose is to prevent an opponent from making a larger bet when facing a check.
When Should You Use a Block Bet?
Consider employing a block bet when these four factors come into play:
- Out of Position on the River: You find yourself out of position on the river, meaning you act first after the final community card is dealt.
- Stronger Hand Than Your Opponent: Your hand is likely stronger than your opponent’s, with more than a 50% equity advantage against their likely range.
- Avoiding Overcalls: Making a standard or large-sized bet in this situation would invite too many better hands to call, potentially costing you more.
- Preventing a Difficult Decision: By checking, you risk your opponent making a challenging decision by betting a substantial amount.
Secondary Advantages of Block Bets
A well-executed block-betting strategy has additional advantages:
- Block bets force your opponent to make an optimal response to your action, which can be challenging, especially if they are unfamiliar with playing against block bets.
- Opponents often fall into two categories when facing block bets: over-bluffing or under-bluffing. Identifying which category your opponent falls into allows you to extract more expected value (EV) by making hero calls against over-bluffers or folding against under-bluffers.
Four Tips for Successful Block Betting
In a recent video, poker coach and professional player Gary Blackwood shared valuable tips on block betting:
Tip #1: Use Block Bets More Often
- Solvers frequently employ block-betting strategies on the river following a check-check scenario. This applies to single-raised pots and three-bet pots alike.
Tip #2: Avoid Block Betting in Position
- Block bets are effective when out of position. Trying to implement them in position is a common mistake. In position, you already control the pot size when your opponent checks, as you act last.
Tip #3: Use Block Bets Only When You Can Get Called by Enough Worse Hands
- The key rule of block betting is that it should be profitable, meaning you can get called by a sufficient number of worse hands. It’s often better to slightly overbet than to underbet. Many opponents, especially at mid-level stakes, struggle to respond correctly to block bets.
Tip #4: Split Your Range
- In many cases, you can incorporate a wider range of hands into your block-betting strategy than you might initially expect. To maintain balance, consider using two bet sizes on the river: a smaller block bet for value and a larger sizing for bluffs, based on a balanced range of value and bluff hands.
In conclusion, block betting is a tactical tool in poker that can be employed strategically when certain conditions are met. Following these tips can help you make better decisions and extract more value from your opponents when using this technique.
