Hold'em table

J8o is within standard 3-handed button opening range, so I open with a min-raise to steal the blinds or play in position.

Queen-two offsuit is far too weak to defend the small blind against a button raise, especially out of position with the big blind still to act. Folding and saving 150 chips is clearly best.

AKo is a premium hand against a button min-raise and a folded small blind, so I 3-bet to build the pot and take the initiative rather than flat.

J8o is too weak to continue against a preflop 3-bet from the big blind.

AKo is a premium hand and I have position on both blinds in 3-max; a standard 3x open builds the pot while retaining initiative and fold equity.

57 offsuit is too weak to continue from the small blind against a button open; folding avoids putting more chips in with a dominated, disconnected hand.

Getting attractive pot odds of over 2:1 closing the preflop action in the big blind against a button open, QJo is a standard defend.

Checking out of position to the preflop aggressor with Queen-high and backdoor draws.

I hold top pair top kicker (A-K on K-high flop) after my preflop raise got one caller who checked. Betting ~60% pot extracts value from worse Kx and charges spade/straight draws while keeping the pot manageable.

We have queen-high with only backdoor equity on a king-high board facing a substantial continuation bet. Folding is standard here.

Three-handed on the button, 95s is playable as a small open to steal the blinds and realize equity in position.

Folding 8c 2c from the small blind facing a button open raise.

83s is far too weak to defend the big blind out of position against a button raise; the dominated-kicker risk and poor postflop playability outweigh the marginal pot odds on calling 150 more.

54 offsuit is too weak to open even from the button in a 3-handed game.

On the button 3-handed, K7o has enough fold equity to open-raise; calling is the weakest option with a dominated king-high hand, and a 3x raise pressures both blinds while retaining positional advantage.

96 offsuit is too weak to continue out of position against a button open; folding saves chips.

A3o plays poorly out of position facing a 3x open from the button, making folding the standard and disciplined play.

A8s is a strong suited ace on the button in a three-handed pot, so I open to 3x rather than flat the big blind and give the blinds a cheap flop.

K3s is too weak to call or 3-bet out of position against a 3bb button open with the big blind still behind.
