Hold'em table

Nine-four offsuit is too weak to profitably open on the button against two unknown opponents. With no chips invested, folding avoids a marginal steal with poor postflop playability.

Button folded, so it's SB vs BB heads-up. K6o is a reasonable raising hand from the SB in a blind-vs-blind spot; raising to 3bb takes initiative and often wins the pot outright.

Suited connector with good pot odds (3:1) and deep stacks, call to see a flop.

As the preflop raiser out of position on a dry 2-8-T board, a small continuation bet with K-high and a backdoor-ish overcard gets folds from many hands the BB defended with and keeps the pot small when called.

I have a weak hand but good position and backdoor draws; calling a small flop bet keeps my range wide and allows me to take the pot away on later streets if opponent shows weakness.

King-high with a gutshot (Q) on a turn card that improves the caller's range; barreling Jc into a flop caller has little fold equity, so check and realize equity cheaply.

I have a flush draw but no made hand, and checking in position lets me see a free river without risking a raise that would force me to fold my equity.

K-high has almost no showdown value; the river completed the flush and paired the board, which is a credible scare card after the turn checked through. A ~65% pot bet should fold out missed straight draws and weak pairs like Tx/Jx often enough to be profitable.

I have a club flush on the river. Raising the minimum for value, as opponent's small river bet could be a worse hand or bluff that may call.

We have king-high with no flush (only four clubs) on a paired, flushed board; villain raised our river bluff and we have no showdown value, so fold.

On the button in a 3-handed game, 65o is a marginal but playable open with position; a 2.5x raise applies pressure on the blinds and keeps the pot manageable.

88 is strong in a 3-handed pot, so I 3-bet to isolate the button and take initiative; I can fold to a 4-bet and evaluate postflop if called.

43 offsuit is too weak to continue against a raise and a three-bet, especially with the original raiser still to act. Folding avoids an unprofitable call or bluff with poor equity and no useful blockers.

65o facing a 3-bet out of position with poor equity and playability; folding is standard.

On the button with a suited gapper, raising applies pressure on the blinds and can take down the pot preflop or give me position postflop. A 3x raise is a standard, controlled investment with 100bb stacks.

T2 suited is too weak to defend from the small blind against a 3bb raise, with the big blind still to act. Poor connectivity and positional disadvantage make calling or bluff-raising unattractive.

J6 offsuit is a weak hand out of position against a button open; folding avoids playing a dominated hand with poor playability.

54 offsuit is too weak for a standard button open at 100bb without evidence the blinds overfold. Folding avoids investing in a hand with low equity and limited postflop playability.

Button folded, so it's SB vs BB heads-up with 67s, a strong suited connector that plays well; raising to 3bb takes initiative and is standard in a blind-vs-blind spot with position disadvantage mitigated by fold equity.

Closing the action with 200 to call into a 400 pot, K4o has enough equity against a small-blind steal to defend, and I can fold to heavy postflop pressure.

Paired low board is good for the preflop raiser's range; a small c-bet with 67s (backdoor flush/straight equity) gets folds from many overcard hands and keeps initiative cheaply.

I have only king-high on a paired board and face a flop bet from the preflop raiser. Without a pair or draw, continuing would be too speculative.

AJo on the button in a 3-handed game is a clear open-raise; standard 2.5x sizing to build the pot with a strong hand in position.

KQo is strong enough to 3-bet against a button open in 3-handed play, and making it 800 denies equity and takes initiative.

94 suited is too weak to cold-call a three-bet, especially with the original raiser still to act. It also lacks useful blockers for a four-bet bluff.

AJo on the button facing a 3-bet from the SB 3-handed; getting ~32% pot odds in position with a hand that dominates much of a loose SB 3-bet range, calling is standard rather than folding or bloating with a 4-bet.

Top pair with a good kicker on a K-high board; I lead for value and to charge flush draws, while maintaining initiative as the preflop 3-bettor.

Ace-high with no draw on a K-high flop facing a 3-bettor's 59% pot c-bet; their range (AK, KK, AA, QQ+) crushes us and we have little equity or playability, so folding is clearly best.

9-6 offsuit is a weak hand even on the button in a 3-handed pot, and calling 100 chips with poor playability postflop is not profitable without reads. Folding preserves chips for stronger spots.

Completing costs only 50 into a 150-chip pot, and 6♥4♥ has enough suited, connected potential to continue heads-up. Calling keeps the pot small while out of position.

Button folded, small blind limped; I'm in the big blind with 2h3c, a weak hand. Checking to see a free flop with position postflop is best; raising with this trash is unnecessary.

I have only six-high with backdoor draws on a connected board. Checking keeps the pot small out of position and avoids investing in a low-equity bluff.

Bottom pair with the worst kicker on a J-T-3 board in a limped pot; betting gets called by better pairs and draws, so checking to see a cheap turn and keep the pot small is best.

We have six-high with no straight or flush draw, and the turn connects with much of the big blind’s range. Checking avoids investing in a low-equity bluff when better semi-bluff candidates are available.

I have bottom pair with a weak kicker on a coordinated board; checking back keeps the pot small and lets me realize showdown value cheaply after opponent has checked twice.

Six-high has virtually no showdown value, and the big blind's checks on both streets suggest a weak range. A 150-chip bluff can fold out unpaired hands without risking an oversized bet.

Bottom pair facing a small river bet (150 into 350 pot, need ~30% equity); opponent's passive limp-check-check line and the many missed straight draws (Q9, 97, 76, 64, A4) make a cheap bluff-catch profitable.
