Hold'em table

Button open with a decent connector hand, raising to build the pot and take initiative in a 3-handed spot.

26 offsuit is too weak to continue out of position against a button open, especially with the big blind still to act. Folding preserves the full stack for better spots.

Ace-four offsuit is too weak to defend against a 2.5x button raise out of position; folding avoids playing a dominated, marginal hand.

QTo is playable from the button in a three-handed pot, so a small open builds the pot and can take it down preflop.

KTs plays well postflop and I'm getting a good price to call a 2.5x button open in position-ish 3-way pot; I'll keep the pot small and evaluate the flop rather than bloat it with a suited connector-ish hand.

T5o offsuit is weak facing a raise and a call; not worth calling out of position.

I have only a gutshot to the jack plus a backdoor flush draw against the preflop raiser, so checking to realize equity cheaply and see their turn action is best.

I have top pair on a draw-heavy flop and the opponent checked, so a two-thirds pot bet gets value and charges flush and straight draws instead of giving a free card.

King-high with no draw on a Q65 board against a preflop raiser's flop bet is far behind; folding is cheapest.

Ace-high from the button in a 3-handed game is a standard open; raising to 2.5x applies pressure on the blinds and can take the pot immediately.

5c2c offsuit is a weak hand facing a raise; folding is correct.

94 offsuit is too weak to continue against a button open after the small blind folds, so folding the extra 150 is the highest-EV line.

K9o is a reasonable button raise in a 3-handed spot; raising to 250 applies pressure with position.

72 offsuit is too weak to continue against a button open; folding saves chips for better spots.

K3o is far too weak to defend the big blind against a button raise; I'm often dominated and out of position with poor playability. Folding and preserving my stack is the highest-EV play.

AKo is a premium hand on the button, so I open to 2.5bb to build the pot and take the initiative rather than just calling.

Nine-three suited is far too weak to call 200 more against a button raise, especially out of position. Folding is clearly best.

With pocket eights heads-up against a button open, I want to build the pot and take initiative rather than just flat-calling out of position.

AKo is ahead of a button-open 3-bet range and plays well as a value 4-bet heads-up. Sizing to 2200 builds the pot without overcommitting 100bb stacks.

4h6c offsuit is a very weak hand from the button with players yet to act behind; folding loses nothing and preserves chips for better spots.

Heads-up now; cheap price to see a flop with 96o, so I'll just call rather than commit more with a weak hand.

75o is too weak to raise for value, and with the button already folded a free flop in position against the limping small blind is the highest-EV line.

Weak holding on a paired flop with a flush draw possible; no need to bet, just check and see next card cheaply.

I have no pair, no draw, and no equity worth betting on this paired flop. Checking keeps the pot small and sees a free turn.

Weak hand with no pair or draw on a paired board; checking to see a free card is best.

I have no pair, draw, or showdown value on a paired board, and the pot is unraised. Checking is the best way to realize a free river rather than bluffing into a passive opponent.

My hand is only a weak pair of deuces with poor kickers; no reason to bet, checking to showdown for free.

I have seven-high with no pair or draw on a paired board, so a river bluff into a two-blind pot is unlikely to be profitable. Checking realizes whatever tiny showdown equity I have for free.
