Hold'em table

Q4o is a weak offsuit hand with poor postflop playability; folding is the disciplined choice in this marginal spot.

Seat 1 folded, so it's heads-up between me (SB) and the BB. Calling 50 to see a flop with Kc9h is reasonable; I'll keep the pot small and play the flop based on texture.

I have a weak K-high with no pair on a J-heavy board, so I want to see a free card and control the pot size. Checking keeps my options open without committing more chips.

We have King-high with no draws on a paired board. Opponent checked, so we can take a free card and see the turn. Betting would risk a check-raise with little equity.

Board is paired with two jacks and an ace, and my K-9 doesn't improve on the turn. Checking keeps the pot small and avoids building a bigger pot with a marginal hand.

I have K-high with no pair or draw on a paired board with an ace. Checking keeps the pot small and avoids value-betting into a likely better hand.

The board is paired with two Jacks and I hold a weak King-high with a 9 kicker. Both opponents checked to me on the river, so there is no pressure to bluff; checking is the safest play to see a cheap showdown.

Opponent checked all streets, so I'm betting with K high to take the pot.

I have top pair on the board with a Kc kicker, which is a decent showdown value. The opponent's river raise is small relative to the pot, so calling is +EV against a wide range of bluffs and weaker value hands.

I have a suited connector in position and want to build the pot while denying the blinds a cheap flop. A 300 total raise is a standard continuation-sized open from the button.

5c3h is a very weak offsuit hand out of position, and calling 200 into a button raise leaves little room to profit against a stronger range.

Tens are a strong hand in a three-handed pot, so I raise to build the pot and put pressure on the blinds.

Q3s is a weak, dominated hand from the small blind facing a button raise, with the big blind still to act. Folding avoids playing a marginal hand out of position in a raised pot.

With only Ace-high and a weak kicker, I don't want to put more chips in against a player who already raised to 300. Folding preserves my stack for better spots.

K8s on the button is strong enough to raise for value and initiative, attacking the blinds in a 3-handed game.

I hold 6h3d, a weak offsuit hand. Facing a 300 raise from the button with only 250 to call, the pot odds do not justify continuing with this speculative hand.

I hold 2c Kh, a weak offsuit hand. Facing a 100 chip big blind with no prior raises, folding is the most expected and chip-preserving choice.

Calling 50 into a pot of 150 gives good immediate odds with a playable hand in a three-handed pot. Folding would be too tight given the cheap price to see a flop.

QTo is ahead of a typical small blind limp range, and I have position; raising for value and to take the initiative.

53o is too weak to continue against a raise to 3bb out of position, with poor equity and playability. Folding saves chips for better spots.

We have a strong pocket pair and position, so we raise to build the pot and take control of the hand.

Q8o is a weak offsuit hand facing a 3x button raise out of position as the small blind; folding avoids playing a dominated hand with poor equity.

With only King-high and a weak kicker, I have no edge against the raiser's range and no reason to continue. Folding preserves my stack for better spots.
