Hold'em table

On the button 3-handed, a small pair like 33 is a standard open-raise; 2.5x gives fold equity against the blinds and keeps position postflop.

Ah-Ks is a premium hand; squeezing from the small blind builds value and applies pressure to the button open and big blind.

Q4 offsuit is too weak to continue against a sizable three-bet, especially with the original raiser still in the hand.

We are in position with about 91bb effective behind a 6.5bb call, which gives enough implied odds to set-mine a small pair against a 3-bet range. Calling is better than folding here, and 4-betting 33 is too thin.

Betting a small continuation size applies pressure in the 3-bet pot while leveraging two overcards, a gutshot to Broadway, and the ace-of-hearts blocker.

Bottom set on a wet two-tone board facing a 3-bettor's c-bet. Raising builds the pot against overpairs, AQ and KQ, and charges the flush and straight draws.

I have the nut-heart draw plus a gutshot to Broadway and two overcards, giving strong equity against made hands. Shoving maximizes fold equity versus one-pair holdings while allowing me to realize my draw equity.

Bottom set on a Q-T-3 two-heart board is well ahead of the villain's shoving range (overpairs, AK, top pair, draws). It is behind only QQ/TT, and we need about 35% equity to call, so calling is clearly profitable.

Open-raise the button with K4 offsuit to leverage position and capture the blinds.

T8 offsuit is too weak to continue from the small blind against a button raise, especially with the big blind still to act.

A6o in the big blind against a 2.2x button open is getting great odds (120 to win 370), so calling is clearly profitable and keeps the hand playable postflop. A 3-bet is also possible but less needed.

Ace-high with the nut diamond backdoor out of position against the button's range; checking keeps the pot small and lets me check-raise or float with the ace of diamonds as a blocker.

A small continuation bet pressures unpaired hands while risking little with king-high and a diamond blocker.

A6 with the nut flush backdoor and an overcard is getting great odds against a small c-bet (160 into 490), so calling is profitable. We keep the button's range wide and have ace-high showdown value.

I have ace-high with the nut flush draw and can realize my equity by checking. Against a reasonable turn bet I can check-call or check-raise, and I avoid bloating the pot out of position.

A half-pot turn bet pressures missed overcards and marginal pairs after the opponent checks, while retaining equity with the diamond draw and king-high.

The backdoor flush draw missed, leaving only ace-high against a flop and turn double barrel. I'd likely face another bet on the river, so calling out of position isn't profitable.

K8 suited is a profitable button open three-handed, with position and decent postflop playability.

K2 offsuit from the small blind facing a button open, with the big blind still to act, is too weak and dominated to continue out of position.

Defend the big blind against a small button open with a suited connected broadway hand that plays well postflop.

Check to the preflop raiser with a gutshot and two overcards, preserving flexibility to respond to a continuation bet.

Top pair with a strong kicker can get value from weaker pairs and draws. A half-pot bet also charges overcards to continue.

Call the small continuation bet with two overcards and a gutshot to a nine, preserving flexibility against the button's wide betting range.

With only a gutshot and modest showdown value on a paired board, checking preserves equity and avoids building a pot against a range that called the flop.

My eight with a king kicker can get value from weaker pairs and draws. A modest bet also charges overcards without committing too much against a seven.

With only jack-high on a paired board and no meaningful draw, calling the turn barrel is unprofitable.

A2 suited is a clear open from the button in 3-handed play, so I'm raising to 2.5bb to take the initiative.

5-3 offsuit is too weak to defend from the small blind against a button raise with the big blind still behind.

7-4 offsuit is too weak to defend out of position against a 2.5-big-blind button raise.

On the button in a three-handed game, Q2 suited is a reasonable opening hand with positional advantage. I raise to apply pressure and retain initiative.

Seven-five offsuit is too weak to defend from the small blind against a button raise with the big blind still to act.

AKs is a premium hand against a button open, so I 3-bet for value to about 4x out of position.

Qs2s is too weak to continue against a substantial three-bet, especially with stacks deep enough to create difficult postflop situations.

A3 offsuit is strong enough to open on the button in a three-handed game. A 2.5-big-blind raise pressures the blinds without risking too much.

65o in the small blind facing a button open, with the big blind still to act behind, is too weak to call out of position or to 3-bet profitably. Folding is standard.

Q4 offsuit is too weak to defend against a button raise out of position in this heads-up pot.
