Hold'em table

T9o is a standard button open against the blinds; a 2.5bb raise takes the initiative and can win the pot immediately.

2c6s is a very weak hand facing a 2.5x raise out of position with a third player still in; folding loses only the 50 already posted and preserves chips for better spots.

Queen-Ten offsuit is marginal, but on the button I have position and can take a small stab for fold equity; a min-raise keeps risk low while building a pot I can play in position.

T5 offsuit is too weak to defend out of position against a button open, even with a decent price. Folding avoids a dominated, low-playability spot.

On the button with Ace-high, raising to apply pressure and take advantage of position in a 3-handed pot.

52s is too weak to continue against a button open; folding saves chips.

94 offsuit is far too weak to defend against a 2.5x button raise out of position with the SB already folded; folding is clearly best.

K9o is a standard button open in three-handed play; raising to 2.5bb takes the initiative rather than limping or folding a playable king.

72 offsuit is one of the worst starting hands and I'm facing a 2.5x raise out of position. Calling 200 more with no equity or playability is clearly -EV, so folding is the correct play.

K3 offsuit facing a raise from BB with SB already folded is not worth defending; fold to save chips.

Ace-king offsuit on the button is a premium raising hand; a standard 3x open builds the pot with position and applies pressure to both blinds.

9d3d offsuit is weak; facing a 3x raise from the button with a call in between, folding is best.

Pocket eights are ahead of a wide button open and the price to continue is only 200 into 450, so calling realizes equity without bloating the pot out of position.

Pocket eights are an underpair on a queen-jack flop, so I check to pot-control and see whether the preflop raiser continues.

I raised preflop and the preflop caller checked a Q-J-3 flop; my AK missed but has two overcards and a gutshot, so a ~60% pot continuation bet folds out many better-checked hands and still builds a pot when called.

Pocket eights is an underpair on Q-J-3, but the 400 bet into 1050 offers a price worth a call out of position rather than a fold or a bloated raise.

Pocket eights are an underpair to the queen and jack with no draw, so a turn bet mostly gets called by better hands. Checking controls the pot and keeps showdown value.

Villain check-called the flop then checked a blank turn, signaling weakness. Betting ~60% pot as a semi-bluff with a gutshot, two overcards, and position generates good fold equity while retaining ten outs if called.

Pocket eights are an underpair with no draw on a queen-jack board, and the button has raised preflop and barreled both flop and turn, so calling 900 is unlikely to be profitable.

4h6c offsuit is a weak hand not worth playing from the button facing a raise; folding preserves chips for better spots.

Button folded, so this is heads-up versus the big blind and 96o is cheap enough to complete for half a blind with decent pot odds.

I'm in the big blind with 7d5s against only the small blind's limp, so I get a free flop with a hand that can make disguised two-pair or straights. Checking keeps the pot small and avoids bloating with a weak holding.

Nine-six offsuit has no pair and no draw on a paired flop, so betting would be a pure bluff with little backup equity. Checking keeps the pot small and realizes a free turn.

I have 7-high with no showdown value, and the limper checked the flop, signaling weakness. A small half-pot bet can take this pot down cheaply, and I can fold if I face resistance.

Nine-high with no pair and no draw has too little equity to call a flop bet on a paired board.
