Hold'em table

A2o is playable as a button open in three-handed poker; a small raise takes the initiative and can fold out worse hands.

K6o is too weak to defend out of position against a button raise, especially with the big blind still to act.

J5 offsuit is too weak to profitably defend against a 2.5bb button raise out of position. Folding avoids investing more with poor playability and frequent domination.

Open-raising with A6s on the button in 3-handed play is standard for value and positional advantage.

T9 offsuit is too weak to profitably defend the small blind against a 2.5bb button raise with the big blind still to act. Folding avoids a marginal out-of-position call or an overly loose three-bet.

85s has enough equity and playability versus a button open to call 1.5bb more from the big blind rather than fold or inflate the pot with a weak three-bet.

I completely missed this flop with no pair and no draw, and I am out of position against the preflop raiser, so checking is the disciplined play.

C-betting small with range advantage and backdoor equity on a queen-high board.

5-8 has only a gutshot on 7-4-Q and no pair or flush draw, so calling 180 is not justified by pot odds or hand strength.

32 offsuit is too weak to profitably open or limp on the button without evidence that the blinds overfold. Folding avoids investing with poor equity and playability.

Button folded, so this is heads-up versus the big blind. J5o is weak, but calling 50 into 150 only needs about 25% equity, which this hand has against a wide blind range.

Holding King-Nine suited in the big blind against a small blind limp, I have an equity and positional advantage, so raising to 350 builds the pot and exerts pressure.

J5 offsuit is too weak to continue out of position against a raise to 350 after completing the small blind.

2c3d offsuit is too weak to open from the button for a full big blind, so folding preserves the stack.

K4o is too weak to play profitably out of position against the big blind.

K9o is well within the standard button opening range in 3-handed play; raising to 2.25bb to steal or play in position.

A2 suited is a useful three-bet bluff against a button open, blocking strong ace hands while retaining nut-flush and wheel potential. The larger sizing applies pressure while compensating for being out of position.

Ten-three offsuit is far too weak to continue against an open and a three-bet, so folding preserves chips.

K9o lacks sufficient equity and playability to defend against a sizable 3-bet from the small blind.

Suited connectors are a reasonable button open three-handed at 100bb depth. Raising to 2.5bb pressures the blinds while preserving positional and postflop flexibility.

QTo is playable three-handed against a 2.5bb button open, and calling 200 keeps the pot small out of position rather than bloating it with a weak three-bet.

Holding 82o multiway out of position is unplayable despite the pot odds, so folding is the clear optimal choice.

Queen-ten missed this low dry flop completely, so I check and let the preflop raiser act rather than bluff into their range advantage.

A pair plus an open-ended straight draw and backdoor spades has good equity and some showdown value. Checking back realizes that equity in position while avoiding a check-raise on a board that connects well with the caller's range.

Queen-high with no pair or draw on a dry turn; checking keeps the pot small and realizes free equity against the preflop raiser.

My pair has showdown value and an open-ended straight draw. Checking behind realizes that equity for free and avoids a check-raise against a range that can contain stronger pairs.

Queen-high has thin showdown value after two streets of checks, and a river bluff into the preflop raiser is unlikely to fold out better hands often enough to be profitable.

My fives have showdown value against unpaired hands, but a river bet is unlikely to get enough calls from worse. Checking avoids exposing this marginal hand to a raise.
