Hold'em table

84 offsuit is too weak to open or limp from the button, so folding avoids putting chips in with a dominated hand.

With pocket fives blind-versus-blind, opening for a raise to 3 bb builds value and exerts pressure on the big blind.

K6 offsuit is too weak to call 200 more out of position against a 3x raise from the small blind; dominated too often and poor equity realization. Folding preserves chips early.

Nine-seven offsuit is too weak to open profitably from the button even three-handed.

Heads-up against only the big blind, A3o has decent equity and blocker value; a small raise to 250 builds the pot with position and applies fold pressure without risking much.

Button folded, so this is heads-up versus a small-blind open and I close the action in position. 9s3s has enough suited equity and playability at this price to defend rather than fold.

Heads-up with top pair on a dry A-7-5 flop, I likely have the best hand and should bet for value and protection rather than check and give a free card.

I have 9-high with no pair, no draw, and no connection to this ace-high flop. Calling 300 into 800 with almost no equity is a clear fold.

64 offsuit is too weak to open profitably 3-handed; a min-raise won't fold out the blinds often enough and limping just donates. Folding preserves chips for better spots.

Button folded, so this is heads-up versus the big blind. Ace-five offsuit is strong enough to raise for initiative rather than flat the extra half blind.

J8s has good playability and equity in position against a small blind open, easily justifying calling 200 chips.

Ace-high with no pair and no real draw on a paired flop is too weak to c-bet for value, so I check and realize equity cheaply.

Flopped trips with a strong kicker in position; checking behind lets the preflop raiser bluff or catch a piece on the turn.

Ace-high with no pair or draw on a paired board is too weak to bet out of position into a caller, so I take the free card.

I have trips with trip eights and a Jack kicker. After the preflop raiser checks twice, I bet for value and protection against draws.

Ace-high with no pair or draw is too weak to call a turn bet on a paired board. Folding saves chips against a range that often has a ten, an eight, or a real draw.

AJo is a strong button open in three-handed play. Raising to 3bb builds the pot and takes the initiative before the flop.

Folding 54o in the small blind against a button open as it is far too weak to defend out of position.

QTo in the big blind has enough equity against a wide button opening range to justify calling 200 into a 450 pot; folding is too tight and 3-betting this hand out of position is risky.

I flopped top two pair (Q-T on Q-5-T) heads-up against the preflop raiser, so I'm betting ~70% pot for value on a dry board with few draws.

In position with a nut gutshot and an overcard, calling 450 into 1100 is priced well enough to continue and reassess the turn rather than fold or inflate the pot with ace-high.

I have the nut straight (A-K-Q-J-T) on a paired-free board with only two spades, so I bet the turn for value after seat_3's check. A 1100 bet into 1550 targets calls from pairs and draws without overbetting.

Ten-six offsuit is well outside a standard button opening range even in 3-handed play.

Pocket nines heads-up against the big blind has strong equity (~70% vs a random hand), so I raise for value and initiative instead of just limping and letting the BB see a cheap flop.

A8o is a reasonable defend in position against a small-blind raise after the button folds, and the price is only 200 into 400. Calling keeps the pot manageable and realizes equity better than folding or bloating it with a 3-bet.

Ace-high with no draw on a paired board has some showdown value but little bluff equity against a preflop raiser, so I check back.

My jacks and nines two pair is now second-best to Qx/Jx/TT and faces one-card club flush draws, so a half-pot turn bet charges draws and folds out one-pair-jacks hands while I keep an easy fold if raised.

Ace-high with no pair or draw on a paired jack-queen board does not have the equity to call a turn bet. Folding avoids paying off a likely made hand.

Queen-nine suited is a strong button opener three-handed with fold equity and playability postflop; a standard 3x raise pressures the blinds without committing too much.

T7o is too weak to continue out of position against a button open; folding avoids a dominated, hard-to-play hand.

KTo is strong enough to defend the big blind against a button open getting over 2:1 immediate odds.

I hit top pair with a decent kicker on a dry board, and checking to the preflop aggressor out of position is standard.

I raised preflop and got one caller; heads-up, backdoor straight/flush draws and unpaired board make a free card fine with Q9s. I can bluff later streets if he shows weakness.

I have top pair with a gutshot straight draw on a wet board. After the flop checked through, I bet for value and protection against various draws and second-best pairs.

My Q9 only makes king-high on the 7-K-8-J board, which beats nothing but pure air, and villain's check-check-then-bet line is heavily weighted toward J-x, K-x, or T9. With no draws and little fold equity, calling the ~28% required equity is -EV, so I fold.
