Hold'em table

K5 offsuit is too weak to open from the button; it is often dominated and plays poorly when called.

9-5 offsuit is too weak to continue even at a discounted price heads-up against the big blind.

Q5o is a weak hand from the button facing two players still to act; folding avoids unnecessary risk.

Pocket nines are strong three-handed; I raise from the SB to build the pot and isolate the BB, applying pressure while I likely have the best hand.

QJo offsuit is strong enough to defend the big blind against a small-blind open once the button folds. Calling 200 into a 400 pot keeps the hand heads-up without bloating the pot with a marginal three-bet.

Top set on a two-diamond board; betting for value while charging any flush draw is clearly best.

QJ has an open-ended straight draw plus two overcards against a single c-bet, so calling 400 into 1000 is the best way to realize that equity without bloating the pot.

I hold a set of nines on a coordinated board with flush and straight draws possible, so betting ~64% pot charges draws and extracts value from one-pair hands. Stacks are deep enough to keep building the pot for later streets.

I have only a straight draw with about eight outs and one card to come, which is not enough equity to call 900 into a 2300 pot. Opponent has shown strength on every street, so I fold rather than chase.

Suited 9-6 on the button is a cheap speculative hand; flatting the 100 keeps the pot small while retaining position and flush/straight potential against both blinds.

A2o is too weak to continue out of position after the button limps, and completing lets the big blind squeeze. Folding avoids a dominated, hard-to-realize hand.

I'm the big blind with a weak offsuit hand and no raise to face; checking is free and keeps my option open.

No pair or draw with 5h6c on a K-J-A board; checking to see a free card rather than bluffing into two opponents.

5h6c has no pair, no draw on a K-J-A board; small bet from button but no equity to continue.

Ace-deuce offsuit is playable as a button open in three-handed poker with position, so I raise to 3x rather than limp or fold.

ATo is a solid hand to 3-bet against a single button open; raising isolates the field and builds a pot with initiative.

AKs has strong equity against a 3-bet range, and calling 800 keeps the pot manageable out of position while letting me realize equity postflop; I can value-bet an ace/king flop or fold cheaply otherwise.

A2o is too weak to continue facing a three-bet and a cold call; it is often dominated and has poor multiway equity.

I only have ace-high with no pair or real draw on a paired board; checking to control pot size out of position.

I have ace-high with no pair or draw on a paired board; checking preserves chips since both opponents already checked the flop.

I only have ace-high with no pair or flush; no reason to bet into two players who may call with better, so I check and hope to win at showdown.

On the button with K8o in a 3-handed pot, a standard raise applies pressure and builds equity with two live overcards potential.

J4 offsuit is far too weak to defend a 2.5x raise from the small blind with a player still to act behind. Folding minimizes losses with a hand that rarely makes strong holdings.

T7o is too weak and poorly connected to defend the big blind against a button open, so folding is the higher-EV play.

Ten-seven offsuit on the button is too weak to open profitably at these stack depths, with decent hands behind. Folding preserves chips for stronger spots.

K3 offsuit is too weak to complete from the small blind out of position after the button folds; folding avoids a dominated, poorly playable hand.
