Hold'em table

7h9s offsuit is weak from the button in a 3-handed pot facing a raise; folding preserves chips for better spots.

Pocket queens are a premium hand heads-up against the big blind; raising builds the pot for value and denies a free flop.

Q7 suited is a reasonable BB defend heads-up against a 3x small-blind open, getting 2:1 with suited connectivity and a queen. Calling keeps the pot small out of position rather than bloating it with a weak three-bet.

QQ is only an underpair to the ace and jack on this flop, so checking controls the pot and lets me bluff-catch rather than building a pot against Ax or Jx.

Queen-high with no pair or draw on an ace-high flop; checking behind the preflop raiser is the standard play.

With QQ on a paired, three-spade A-J board, opponent's flop check-back suggests weakness; a half-pot bet gets value from lower pairs and draws while keeping the pot manageable.

Queen-high with no draw on an ace-jack paired board is far too weak to call a turn bet. Folding avoids putting more chips in with almost no equity.

Q3o is weak but in position on the button three-handed, calling one big blind offers good pot odds and positional advantage to realize Q-high equity cheaply.

A6 suited is playable from the small blind for a half-blind complete after a button limp, so I call rather than fold or inflate the pot out of position.

I'm big blind with Q8 offsuit, no raise to face, checking is free and avoids building a pot out of position with a weak hand.

Ace-high with no pair or draw on a dry flop; no reason to bet into two opponents, so I check and realize equity for free.

I have middle pair with a decent kicker on a dry board, and both opponents checked, so a small value/probe bet makes sense.

With Q-high, no pair and no real draw on J-8-2 facing a flop bet with a player behind, calling 175 lacks sufficient equity.

A6 of diamonds completely missed this flop with no pair or draw, so calling 175 into 475 is not justified against a flop raise.

K2 offsuit is too weak to open even from the button in three-handed play; folding avoids putting chips in with a dominated, disconnected hand.

Heads-up pot after button folds; QTo is a solid hand to raise for value/steal against BB's wide range.

J9o has sufficient equity against a small-blind raise and I will be in position heads-up, so defending the big blind with a call is profitable.

I have top pair of queens with a king on board; betting for value and to protect against draws.

With J9 on K-Q-4 I have only a gutshot to a ten, about 4 outs, which is far below the equity needed to call 400 into 1000 against the preflop raiser's likely strong range.

Qd2c is a weak offsuit hand on the button facing a raise-equivalent situation; not worth investing chips here.

AKo is a premium hand heads-up from the small blind after the button folded. Raising to 3x builds the pot for value and denies the big blind a free flop.

AQ is a premium hand and I am out of position against the small blind's open, so a 3-bet to 900 builds the pot and takes the initiative rather than flatting.

AKo is a premium in 3-handed play, blocking AA/KK, and I am out of position if I just call. A 4-bet to about 2.3x the 3-bet applies pressure and builds value against a wide BB 3-betting range.

AQo is dominated by a typical small-blind 4-bet range and plays poorly out of position, so folding is better than calling or 5-betting.

Pocket sevens are strong 3-handed on the button; raising builds value and takes initiative with position.

J2o is too weak to continue from the small blind against a button open, with the big blind still to act.

K4 offsuit is weak against a button raise; not worth calling out of position.

K6 offsuit is too weak to open from the button in three-handed play; folding avoids a dominated, poorly playable hand out of position postflop.

Heads-up with a suited king, raising to apply pressure and build the pot with a decent hand.

5-3 offsuit is a very weak hand even heads-up against a small-blind raise; calling 150 chips would be negative expectation.
