Hold'em table

On the button in a three-handed pot, a small open with 76o applies pressure and can take the blinds or realize equity in position.

K3 offsuit is too weak to defend from the small blind against a 2.5bb button raise with the big blind still to act. Its domination risk and poor equity realization out of position favor folding.

6-2 offsuit is the weakest hand and is out of position against a button raise to 250. Calling 150 to win a 400 pot is not worth it, so I fold.

Pocket queens are a premium hand three-handed. Raising to 2.5 big blinds builds a pot in position while allowing weaker hands to continue.

8-6 offsuit from the small blind facing a button raise to 250, with the big blind still left to act, is a weak hand that plays poorly out of position. Folding is the best option.

T5o is too weak to continue against a button open; folding avoids a dominated, poorly connected hand out of position.

JTo on the button in a 3-handed game is a strong enough hand to open for a raise. Raising to 2.5bb takes the initiative and lets me play with position.

K6 offsuit is too weak to call a button open from the small blind with the big blind still to act. Folding avoids putting more chips in with a dominated, low-equity hand.

KQo is strong against a button opening range and blocks several premium hands. A substantial three-bet extracts value from weaker calls and compensates for playing out of position.

JTo facing a 3-bet to 11bb from the big blind is weak: calling 8.5 more out of position-ish with a dominated offsuit hand is not profitable, so I fold.

K4 suited is playable from the button in three-handed play, so I open to 2.5bb to take the initiative rather than limp or fold.

72 offsuit is too weak to defend against a button raise from the small blind, with poor equity realization out of position and the big blind still to act.

J9o in the big blind against a button min-ish raise of 2.5bb: I get 400+150 pot odds (about 27% equity needed) and J9o has enough equity and a positional disadvantage that's acceptable, so calling is better than folding or bluff-raising.

I have jack-high with a backdoor flush draw on a Q-2-2 board, and I'm first to act out of position against the button's preflop raise. Checking keeps the pot small and lets me see what the button does.

King-high with no pair or draw on Q22 has little equity, so I check back rather than bluff into the preflop caller.

I have a pair of nines, which is likely the best hand on this Q-2-2-9 board after the flop checks. The button checked back the flop, so its range is capped. A small bet of about half the pot gets value from worse pairs and Qx hands and denies equity to overcards and draws.

King-high with no pair and no draw is too weak to call a turn bet after the flop checked through.

Opening 8-7 offsuit on the button can profit from blind steals and positional advantage in this rake-free game. A small raise limits investment while retaining useful straight potential when called.

Q9o from the small blind facing a button open of 2.25bb with the big blind still to act behind is weak and plays poorly out of position in a three-way pot, so folding is the disciplined choice.

52 offsuit is too weak to call a button raise from the big blind, so folding is the highest-EV option.

Pocket sixes on the button in a 3-handed game is a strong hand, so I raise to 3bb for value and to take position.

Q9s is too weak to continue out of position against a button open with the big blind still to act.

85 offsuit is too weak to defend profitably against a 3bb button raise out of position. Its poor playability and lack of useful blockers also make it an unattractive three-bet bluff.
