Hold'em table

Pocket aces on the button is the nuts preflop; a standard 3x raise builds the pot for value while keeping both blinds in with worse hands.

A7o is too weak to continue out of position against a button raise with the big blind still to act, so folding avoids a dominated spot.

87s is a playable suited connector on the button in a 3-handed pot, so I open to 2.5bb to take the initiative rather than limp.

J9o offsuit facing a raise from the button with a call cold; not strong enough to continue profitably out of position.

KQs is far too strong to fold and calling leaves me out of position against the button's range; a 3-bet to ~3.2x applies pressure and can win it outright or build a pot where I dominate their continuing hands.

87s has enough equity and plays well in position against a BB three-bet, and the price is too good to fold. Calling keeps the pot manageable rather than turning the hand into a bloated four-bet pot.

I have only backdoor club equity and no pair on an ace-king flop after calling a 3-bet, so I take the free card in position rather than bluff.

I flopped/turned trip kings with the Ks in hand; only AK-outdrawn hands beat me, so I bet ~70% pot for value against the preflop caller's range of strong aces, kings, or draws.

I have eight-seven offsuit with no pair, no draw, and no equity against a turn bet on a paired ace-king board. Folding is the only profitable option.

T4o offsuit from the button with weak connectivity is not worth entering a 3-way pot for; folding preserves chips.

Heads-up after the button folds, 75s has decent playability and a small raise builds fold equity while keeping the pot manageable out of position. Calling is too passive with a hand that plays well as a semi-steal.

K6s has enough suited-king equity and postflop position versus a small-blind open to call 150 into 350 rather than fold or inflate the pot.

I flopped trip fives (5h with the paired board), so I'm betting ~70% pot for value against overpairs, eights, smaller pairs, and draws while denying a free card.

King-high with no pair and no draw on a paired board is too weak to continue against a flop bet. Folding avoids putting more chips in with almost no equity.

Suited connector on the button in 3-handed play is a standard steal; a 3x open puts pressure on the blinds and I keep position if called.

Pocket tens are ahead of a button open and play best as a 3-bet for value and isolation before the big blind acts. Raising to 1000 is a standard size that builds the pot without overcommitting.

J3o facing a raise and a 3-bet is far too weak to continue; easy fold.

4c7c is far too weak to call a 3-bet; I'd need ~33% equity and dominated suited connectors rarely get there against the small blind's raising range. Folding loses the minimum.

A7s is a clear button open in three-handed play. A 2.5x raise builds the pot with a suited ace while keeping the price reasonable against blinds.

Weak offsuit hand (7h Td) facing a raise from the button; not worth continuing out of position.

Defending my big blind against a button open at a good price (need ~21% equity, 89o has decent playability vs a wide BTN range). Calling keeps the pot small out of position rather than 3-betting a marginal hand.

I hold second pair (nines) with a weak kicker out of position against the preflop raiser on a dry K-high board with no draws; checking keeps the pot small and induces bluffs from worse A-high hands.

Dry king-high flop favors my preflop-raiser range, and the big blind checked. A small c-bet pressures missed hands while keeping the price low with ace-high and a backdoor club draw.

Second pair of nines with a small continuation bet to call; the price is cheap and my hand is likely ahead of a float or missed c-bet, so I'll continue and reassess on the turn.

Ace-high has no pair or draw on a paired king board after a flop call, so barreling is unlikely to be profitable. Checking keeps the pot small and realizes whatever showdown value remains.

My pair of nines has decent showdown value against a preflop raiser who gave up on the turn, but betting only folds out hands I already beat (ace-high, busted draws) and gets called by K-x, Q-x, better nines, or a flush. Checking keeps the pot small and lets weaker hands bluff or check back.

Ace-high has little showdown value on this paired, three-spade board, but a river bluff is unlikely to fold a hand that called the flop. Checking is free and avoids putting more chips in with air.

7-5 offsuit on the button facing a raise-limp scenario isn't strong enough to invest chips; fold and wait for a better spot.
