Holdem table

QJ offsuit on the button is a solid raising hand heads-up against two players; standard open-raise sizing to build the pot and take initiative.

K3 offsuit is too weak to continue from the small blind against a button open, especially out of position with the big blind still to act. Folding avoids a dominated, low-equity spot.

52 offsuit is nearly the worst hand in poker and calling 150 more against a 2.5x raiser with no positional edge is clearly -EV; folding is the best play.

Q6o is too weak to open from the button in three-handed play; it is dominated often and plays poorly postflop, so folding is the higher-EV default.

Heads-up SB vs BB with the button folded, 76o has decent equity against a wide blind range plus fold equity, so a standard 3x raise is more profitable than limping or folding.

Pocket aces preflop with only one opponent left; raise for value to build the pot.

76 offsuit is far too weak to call a 3-bet out of position against the big blind; the 300 already invested is sunk cost, and folding saves 700 more.

Only 1bb to call from the button with pot odds around 29%, and Q3o has enough equity against two random hands to justify seeing a flop in position. Folding is too tight for this price.

KTs is strong enough to raise for value/isolation against a limper, building the pot with a hand that plays well multiway.

J9o is too weak to continue out of position against a small-blind isolate, especially with the button still able to come along. Folding avoids a dominated, poorly realized spot.

Q3o is far too weak to call a raise over my limp; my queen is dominated and the hand has almost no equity against the SB's raising range. Folding loses the least.

On the button 3-handed with a suited hand, a small raise applies pressure to steal the blinds cheaply.

K8s is playable versus a 2.5bb button open in three-handed play, and calling keeps the pot manageable while retaining suited-king equity out of position.

T7 offsuit is far too weak to defend the big blind against a button raise plus a caller, and calling 150 into a raised pot with a hand that flops poorly loses the least here.

Top pair on a dry flop is worth a small out-of-position value and protection bet against the button's wide open. A third-pot size keeps worse pairs and ace-high in while limiting damage if I am behind.

J-high with only a backdoor flush draw has too little equity against a flop bet on a Q-K-5 board; folding is cheap and avoids bleeding chips.

A9s is a standard button open in a three-handed game, so I raise to 2.5bb to take the initiative and fold out weaker hands.

KQo is too strong to fold three-handed against a button open, and calling out of position with the big blind behind is unattractive. A 3-bet to 800 builds the pot with a premium hand while retaining fold equity.

T2o is weak and facing a heavy 3-bet reraise; folding preserves chips.

A9s is too dominated to continue against an 8bb small-blind 3-bet; pot odds are only marginal and reverse implied odds are poor, so folding is the higher-EV line.

7-3 offsuit is a weak hand heads-up vs BB; folding is cheap since only 50 more to call but hand has poor equity and no fold equity postflop.
