Hold'em table

ATo is a standard button open in three-handed play, so I raise to 2.5bb to take the initiative and fold out weaker hands.

5-3 offsuit is one of the worst hands in poker, and calling 200 more to contest a raised pot out of position with the big blind still to act is unprofitable. Folding preserves chips for a better spot.

K6o is too weak to defend out of position against a 2.5bb button open.

Suited connector 8d7d on the button in a 3-handed game is a standard open-raise; position and playability justify building the pot at 3x.

Holding 3h 2d out of position against a button open is an easy fold with virtually zero equity and playability.

AQ offsuit is ahead of a button open in three-handed play, so I 3-bet to 900 to take the initiative and deny cheap equity.

Getting ~2.1:1 pot odds with 87s in position against the BB's 3-bet; the hand has enough equity and playability (flush/straight potential) to set-min... to call and realize equity postflop with position, rather than fold or 4-bet a marginal hand 100bb deep.

I have top pair with a strong queen kicker on an ace-high flop and the button called my preflop 3-bet, so a half-pot value bet gets money in against weaker aces, kings, and draws.

I hold 8-high with no pair and no real draw on an AK6 flop against a preflop 3-bettor who c-bet 800 into 1850. With almost no equity and a strong opposing range, calling or bluff-raising loses chips long-term, so folding is clearly best.

K2o is too weak to profitably open from the button even in 3-handed play.

Button folded, so I am heads-up with a pocket pair against the big blind. A small raise takes the initiative and builds the pot with a hand that is ahead of a wide calling range.

Q2o is far too weak to defend the big blind against a 3x raise from the small blind; I'd be calling 200 into a 400 pot out of position with a hand that's dominated by better queens and flops poorly. Folding is clearly the highest-EV play.

35 suited is too weak to open from the button into two live blinds, and limping is unattractive. Folding avoids a dominated, low-equity spot.

AK offsuit is a premium hand and heads-up against only the big blind, I should raise for value to build the pot and put pressure on a wide BB range.

A5s is a prime 3-bet candidate from the big blind against a small blind raise, possessing strong blocker value and postflop playability.

AKo is far too strong to fold and calling out of position with a hand that misses the flop often is awkward; 4-betting applies pressure, isolates against a wide 3-handed 3-bet range, and builds a pot where I dominate worse aces.

A5s was used as a 3-bet bluff, but facing a substantial 4-bet from the small blind, it lacks the required equity to continue profitably.

On the button three-handed I should attack the blinds with a wide range, and K4o has decent fold equity acting last on every street. A standard 2.5x open keeps pressure on without risking much.

Holding A8s in the small blind against a button open, a 3-bet to 10bb applies pressure, leverages our blocker, and denies equity to the big blind.

KQo is dominated and plays poorly out of position against a 10bb three-bet; with only the big blind invested, folding is the higher-EV choice versus calling or four-bet bluffing.

K4o is far too weak to call a 3-bet; I'd need roughly 36% equity to call 750 into 1350, and K4o is dominated by any reasonable 3-betting range. Folding preserves chips for better spots.

Nine-three offsuit is far too weak to open raise or play, even from the button in a 3-handed game.

KJo is ahead of a random big-blind range heads-up after the button folds, so I raise to 3bb to build the pot and take the initiative.

King-six offsuit is dominated by the small blind's raising range and plays poorly out of position postflop; folding to a 3x raise is the standard, highest-EV play.
