3-bet defense trainer
A 3-bet defense trainer should drill the decision after you open and face pressure: call, four-bet, or fold. The right answer depends on the opening seat, three-bettor position, sizing, blockers, stack depth, and postflop playability.
Direct answer
A good 3-bet defense trainer teaches which hands continue after facing a three-bet, why position changes the defense range, and when blocker hands become four-bet bluffs. It should review repeated leaks such as loose out-of-position calls, missed value four-bets, and overfolding late-position opens.
Defense starts with your opening range
An under-the-gun open and a button open do not defend the same way. Training should first identify the range that opened, then compare the hand against that range before choosing call, four-bet, or fold.
Position and sizing change the continue range
In-position calls realize more equity and can include more suited, connected, and pair-heavy hands. Out-of-position calls need stricter discipline, especially when the three-bet size creates awkward stack-to-pot ratios.
Four-bet practice needs blockers and value
A four-bet range needs clear value hands plus selected blocker bluffs. A trainer should separate hands that can call profitably from hands that work better as folds or four-bet bluffs because of blocker value.
Practice prompts
- Compare cutoff versus button defense against the same blind three-bet size.
- Sort each hand into call, four-bet value, four-bet bluff, or fold before checking feedback.
- Review three missed defenses and tag them as position, sizing, blocker, or realization mistakes.
Common questions
What should a 3-bet defense trainer teach?
It should teach call, four-bet, and fold decisions by opening range, position, three-bet size, stack depth, blockers, and equity realization.
Which 3-bet defense leaks should I review first?
Start with loose out-of-position calls, overfolding late-position opens, missed value four-bets, and random four-bet bluffs without relevant blockers.
