Hold'em table

A9 offsuit with an ace blocker is a strong enough button opening hand in three-handed play. A standard raise applies pressure to the blinds while retaining postflop flexibility.

T6o from the small blind facing a button open, with the big blind still to act behind, is a clear fold; calling out of position with a weak offsuit hand loses money.

AK suited is strong enough to three-bet against a button open, especially from the big blind where calling leaves me out of position.

A9 offsuit is not strong enough to continue profitably against a large 3-bet after opening, especially out of position postflop.

Qc3c on the button in a 3-handed game is a reasonable steal candidate, since only the blinds are left to act. A small open to 2.5bb pressures them cheaply.

AQ offsuit is strong against a button opening range. Raising from the small blind builds the pot and avoids inviting the big blind in cheaply.

9-high suited is far too weak to continue facing a large squeeze out of position.

Q3s is too weak to continue against a large SB 3-bet to 11bb. Calling 850 into 1450 without enough equity or playability is -EV, and a 4-bet bluff is unnecessary.

9♠2♠ is too weak to open profitably from the button against two unknown blinds.

7-2 offsuit is too weak to defend from the small blind heads-up against the big blind, especially with no positional advantage postflop.

A3 offsuit is too weak to profitably enter from the button in this short-handed setup without reads.

Blind vs blind with 87 suited is a strong enough hand to open-raise from the small blind, and raising gives fold equity plus initiative. 3x is a standard size.

A8 offsuit is strong enough to defend against a small-blind raise. Calling keeps weaker hands in the pot and lets me play in position after the flop.

Open-ended straight draw (J or 6) with backdoor potential on a board that favors the preflop raiser's range. A small c-bet of about a third of the pot applies fold equity while keeping the draw's equity if called.

The small flop bet gives me favorable pot odds in position. Ace-high has some showdown value and a chance to improve, so I’ll call.

The turn gives us the nut straight (6-T). We bet about 70% of the pot for value and to charge the diamond flush draws and pairs.

A gutshot and a potentially live ace are not enough to justify calling 700 into a pot of 1700 against this turn bet.

AQo is a strong hand on the button in 3-handed play, so I'm opening to 2.5bb for value and position.

7-5 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act.

T3 offsuit is too weak to defend against a button raise at this sizing.

T4 offsuit is too weak to open profitably from the button against two unknown opponents.

Complete the small blind with a suited jack against the big blind and realize equity heads-up.

A7 suited is well ahead of a small blind limping range, so raising for value and initiative beats checking. 4x is a standard size in position against a limp.

Jh5h is too weak to defend against a large big-blind isolation raise out of position.
