Hold'em table

Pocket aces preflop as button in 3-handed play; raise for value to build the pot.

A7o is dominated and out of position against a button open, with the big blind still to act. Folding avoids a marginal multiway spot with poor playability.

J9s has good playability against a button open; calling 200 to see a flop with position disadvantage but suited cards and a 4.5x pot odds price is a standard defend.

I have second pair (jacks) against a preflop raiser; out of position, check-calling keeps the pot small and lets me evaluate their aggression on later streets.

I hold top overpair (AA) on a dry K-J-4 board; betting for value after opponent checked.

I hold middle pair (jacks) on a K-J-4 board; calling 450 into 1100 keeps worse one-pair hands and draws in while avoiding bloating the pot out of position against the preflop raiser.

I hold second pair (jacks) against an aggressive preflop raiser who barreled the flop; checking keeps the pot small and avoids building it while behind ranges like AK, KJ, or JJ.

I hold pocket aces, an overpair to the board; betting for value against a likely King-high hand while keeping them in with a moderate sizing.

87s is a strong suited connector on the button, so I open to 3bb to take the initiative and build a pot with good playability.

J9 offsuit is too weak to call a 3x raise out of position in the small blind three-handed; folding preserves chips for better spots.

KQs is a premium hand heads-up against a single raiser; 3-betting for value and to isolate the button.

87s has enough suited-connector playability in position against a button-open 3-bet to continue rather than fold the 300 already invested.

I hold top pair (KQ) on a K-3-A board; betting for value while my kicker still has some strength, sizing to build the pot but leave room to fold if raised hard.

87cc has no pair and only backdoor equity on AK3 against a preflop 3-bettor who is c-betting. Calling 1200 is not justified, so I fold.

T4 offsuit is one of the weakest hands and I'm out of position postflop even from the button in a 3-max game. Folding preserves 100bb for better spots.

Suited hand, cheap to see a flop heads-up against BB; not worth raising or folding here.

Heads-up vs a SB limp, K6s has enough playability to raise and take the pot or build it in position-free BB. A small raise to 400 pressures weak limps without overcommitting.

7h5h offsuit is weak against a raise from the big blind; folding avoids investing more chips in a marginal spot.

Suited connector on the button, cheap price to see a flop in position.

Pocket tens are well ahead of a button limp and the big blind, so I raise to build the pot and take the initiative before the flop.

J3 offsuit is far too weak to call 350 into a raise-plus-limp pot; my equity against two players doesn't justify the price. Folding preserves chips for better spots.

4c7c offsuit is weak, facing a raise with a caller already folded; not worth continuing.

A7s is a clear button open in three-handed play, so I raise to 2.5bb to take the initiative and fold out weaker hands.

Ten-seven offsuit is far too weak to defend against a 2.5x button raise out of position with the big blind still to act. Folding loses only the 50-chip blind.

89o offsuit facing a raise heads-up out of position is not worth defending; folding is the disciplined play.

75o from the button is too weak to open profitably 3-handed with no reads; folding preserves chips for better spots.

J3 offsuit is weak, and with the button already out it's not worth completing against the big blind.
