Hold'em table

I'm on the button with Ace-high; a standard raise builds the pot while I have position for the rest of the hand.

Folding JTo out of position from the small blind facing a button open.

Q3o is too weak to defend out of position against a button raise, and folding avoids playing a dominated hand postflop.

K7o is a profitable open from the button in 3-handed play to attack the blinds with position.

9d2s is a very weak offsuit hand in the small blind facing a button raise; folding avoids playing a dominated, low-equity hand out of position.

KJ offsuit is playable heads-up against a standard button open; calling keeps the pot controlled while retaining position disadvantage is offset by hand strength.

I only have second pair (jacks) with an ace on board that likely improves my opponent's range, so I'll check and control the pot size.

As the preflop raiser on an Ace-high dry flop, I have a significant range advantage and can take down the pot with a small continuation bet.

A7s on the button is strong enough to raise for value and initiative in a 3-handed game, and a 3x raise can fold out weaker blinds or isolate.

A8 offsuit has reasonable equity against a wide 3-handed button raise, and pot odds justify a call rather than folding or raising.

Holding Ah4h in the big blind getting excellent pot odds (200 to win 700) closing preflop action, calling is profitable.

Ace-high with only a backdoor flush draw on a dry-ish board; no reason to bet into two opponents, check and see next card cheaply.

I flopped bottom pair with an ace kicker in a multiway pot with the preflop raiser yet to act behind me, so checking is standard.

Continuation bet with ace-high and backdoor flush draw; opponents checked, indicating weakness, so a bet can take down the pot.

Ace-high with a backdoor draw doesn't justify calling a bet into two checkers on a dry board; better to fold and wait for a stronger spot.

Facing a 2/3 pot bet on a coordinated broadway board with only bottom pair and no backdoor draws, folding is the standard disciplined play out of position.

T7 offsuit is weak even on the button in a 3-handed game; folding avoids investing chips in a marginal spot.

Folding 87 offsuit from the small blind as it plays poorly out of position postflop.

Holding 74 offsuit on the button is well outside any profitable opening range in 3-handed play. Easy fold.

Getting 3:1 with J6o against a single big blind; folding would forfeit the 50 already posted, and calling is +EV despite being out of position.

A8o is a reasonable hand heads-up against a limper; a small isolation raise builds value and takes initiative.

J6o is too weak to continue against a raise, especially out of position.

54s on the button with a small blind discount; calling 100 to close the action with a cheap, well-disguised suited connector is fine.

Cheap price to see a flop from the small blind with a king-high hand; folding here isn't necessary given the pot odds.

I have a weak hand in the big blind facing two limpers, so taking a free flop is optimal.

I have king-high with no pair and only a backdoor diamond draw, so checking is the best option to see a free card without committing chips.

I have no equity with six-high on an Ace-Queen flop in a multiway pot, so checking for free is the straightforward play.

With only a weak gutshot and no pair on an ace-high board, checking keeps the pot small and takes a free card in position.

I only have king-high with no pair or draw, so checking to see a free card is best.

I have an inside straight draw with very little showdown value, but checking allows me to realize equity for free without risking chips.

All checked to me on the turn; my pair of fives has some showdown value, but betting can fold out better hands like Qx and I have equity with a gutshot and two-pair outs if called.

King-high with no pair or draw on a board that favors a small-bet value/bluff; not worth calling a turn raise after checks.

I only have a gutshot straight draw with 4 outs (roughly 9% equity) facing a 200 chip bet into a 500 chip pot, which does not offer sufficient direct or implied odds out of position.
