Hold'em table

On the button 3-handed, 9-7 offsuit is within a wide opening range and plays well in position; raising applies pressure to the blinds rather than limping.

QQ is a premium hand; 3-betting the button's open builds the pot and narrows the field while I have strong equity.

Q7s is too weak to continue out of position against a button open and a small-blind 3-bet to 9bb. Folding avoids a dominated spot with poor equity and reverse implied odds.

7-9 offsuit is weak facing a 9bb three-bet from the small blind; calling 650 needs more equity than this hand has against a strong range.

Q3 offsuit is a weak hand from the button facing a raise-less limp situation; folding preserves chips given poor equity and no position advantage postflop against two players.

Button folded, so this is heads-up versus the big blind with suited ace-six. A small raise builds the pot and takes the initiative rather than just completing.

Q8o is a reasonable big-blind defense heads-up against a small-blind 3x open, and I will have position postflop for only 200 more into 400.

Ace-high with no pair or draw on J82 has some showdown value but little reason to bet into the caller. Checking keeps the pot small and sees a free card.

With second pair and a queen kicker after the preflop raiser checked, I likely have the best hand; a half-pot bet protects against overcards and straight draws while getting value from weaker hands.

Ace-high with no pair and no draw on 8-2-J; calling a half-pot flop bet is unprofitable against a range that can have pairs and better aces.

K2o is too weak to open from the button in a three-handed pot; it has poor playability and little equity against continuing ranges. Folding preserves chips for better spots.

QTo is a strong broadway hand heads-up from the small blind after the button folded; raising builds the pot with initiative and fold equity against a wide big blind range.

J9o is playable heads-up getting 3:1 pot odds against a single raiser; calling keeps the pot small while seeing a flop.

Middle pair of queens on a dry K-Q-4 rainbow board as the preflop raiser; a half-pot c-bet gets value from worse pairs and gutshots while folding out air.

Q2 offsuit is a weak holding even on the button in 3-handed play; calling 100 chips risks more postflop with poor kicker and no suited/connected value.

AKo is a premium hand; button folded, so I raise to build the pot against the big blind.

AQ offsuit is ahead of a small-blind open after the button folds, so I 3-bet to about 3x for value and fold equity.

AK is strong enough to 4-bet here; applying pressure on the big blind's 3-bet while stacks are still deep enough to play postflop if called.

AQo is dominated by a tight 4-bet range of QQ+ and AK, and calling or shoving only continues against hands that have me crushed. Folding preserves my stack.

Pocket pair on the button; raise for value and to isolate against the blinds.

J2 offsuit from the small blind is too weak to call a button open; folding avoids playing a dominated, unsuited hand out of position.

K4 offsuit is too weak to defend the big blind out of position against a 3x button raise; its raw equity is marginal and realizability is poor.

K6 offsuit is too weak to open first-in even from the button in three-handed play; it is easily dominated and does not play well enough to justify a raise or a call.

Heads-up after button fold, Kh4h is ahead of BB's random range and suited with king high, so raising to steal and build value is better than limping.

53o is a weak hand facing a raise; folding is best from the big blind against a 2.5x raise with only 150 to call but poor equity and no position.
