Probe Bet from BTN

Overview

A probe bet is typically made on the flop or turn by the pre-flop caller (not the pre-flop raiser). When the pre-flop raiser (e.g., big blind or early position player) checks on a street, the button (BTN) player seizes the opportunity to bet, testing the opponent's hand strength or taking down the pot immediately.

Applicable Scenarios

• Flop: When the pre-flop raiser (e.g., big blind) checks, the button may use a probe bet with medium-strength hands (e.g., top pair weak kicker) or draws to gain information or force a fold.
• Turn: If both players check on the flop, and the pre-flop raiser checks again on the turn, the button often bets to attempt to steal the pot or force weak made hands to fold.

Purpose

• Information gathering: Opponent's reaction (call, raise, or fold) reveals their hand range.
• Stealing the pot: Take down the pot when the opponent shows weakness.
• Protecting hand: With a weak made hand (e.g., bottom pair) and concern about opponent's draws, betting forces draws to fold.

Considerations

• Frequency control: Overusing probe bets makes them exploitable. Adjust based on opponent's style and range.
• Position advantage: The button has position, allowing observation of opponent's action before deciding. After a probe bet, the button can adjust based on the reaction.
• Board texture: Probe bets are more effective on dry boards (no straight or flush draws); on wet boards (many draws) they are more likely to be raised.

Example

• Pre-flop: Button calls the big blind's (pre-flop raiser's) raise. Flop: K♠ 7♦ 2♣. Big blind checks. Button bets about half pot. This is a probe bet to test if the big blind has a king.
