Hold'em table

With the button and no prior action, a small open can profitably pressure the blinds. Suited cards provide some postflop potential when called, and position helps realize that equity.

5c9c is a weak suited connector out of position against a button raise, with the big blind still to act. Folding avoids playing a marginal hand from the worst position.

Nine-deuce offsuit is too weak to defend profitably against the button raise, even with favorable pot odds. Its poor playability out of position makes folding preferable.

I have a weak Ace but position on the button; calling 100 to see a flop in a 3-handed game with 100bb stacks is reasonable to keep the pot small and use my positional advantage.

Despite the cheap completion, 7-3 offsuit has poor playability from the small blind and the big blind can still raise. Folding avoids investing more with a weak hand out of position.

Check to see a free flop with suited connectors. Raising out of position with five-high would inflate the pot without a clear advantage.

I have no pair beyond the board and only a backdoor flush draw. Checking keeps the pot small out of position without investing in a low-equity bluff.

I have trips with an Ace kicker on a paired board with two hearts; betting for value and to protect against draws.

I have no meaningful made hand and only a weak backdoor flush draw on a paired board. Facing an 80%-pot bet out of position, continuing is not profitable.

Pocket sevens are a strong opening hand on the button three-handed. Raising to 2.5 big blinds builds value, pressures the blinds, and preserves positional advantage if called.

T6 suited is too weak to defend from the small blind against a 2.5bb button raise with the big blind still to act. Folding avoids a marginal pot out of position.

Q7s is too weak to defend out of position against a 2.5x button raise; calling would require realizing over 27% equity, but reverse implied odds and positional disadvantage make it a marginal fold.

Eight-six offsuit is a weak button opening candidate with limited high-card strength and poor playability. With no reads suggesting the blinds overfold, folding avoids a marginal investment.

Q3o is not premium, but I am getting 3:1 on a 50-chip completion and the big blind is the only opponent, so calling to see a flop is profitable enough.

Ace-ten offsuit is strong against a small-blind limping range, and we have position postflop. Raising to four big blinds builds value against weaker calls while denying cheap equity.

Q3o is too weak to continue against a 4x raise from the BB, especially out of position.

Ac6s is a playable suited ace on the button in three-handed play. Raising puts pressure on the blinds and builds the pot with a hand that can flop well.

J9 offsuit is too weak to defend profitably from the small blind against a 3bb button raise. Poor position and the big blind still to act make calling unattractive, while this hand is a weak three-bet candidate.

T8 offsuit is a marginal defense against a 3bb button raise and realizes equity poorly out of position. With no evidence of an unusually wide opening range, folding is preferable.

With no rake and the button, K3 offsuit is a reasonable small open to pressure the blinds. A minimum raise keeps the steal inexpensive while retaining position if called.

42 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act. Folding avoids investing more chips with poor equity and positional disadvantage.

J4o is a very weak hand and not worth defending from the big blind against a button raise; folding loses only the blind and preserves my stack.
