Hold'em table

A5 suited on the button is a strong 3-handed opening hand; I raise to 300 to build the pot with position and apply pressure on the blinds.

Queen-ten offsuit has enough high-card equity against a wide three-handed button open to continue, and a three-bet out of position is unattractive with this hand. Calling keeps the pot manageable while seeing whether the big blind comes along.

Queen-ten missed this flop and I am out of position against the preflop raiser, so checking keeps the pot small and lets me see the turn before committing more chips.

I raised preflop with A5s and the flop checked to me; a small continuation bet applies pressure and can take it down, with an overcard and gutshot outs if called.

Queen-high with no pair and no draw is too weak to continue out of position against a flop bet.

J5 offsuit is too weak to call or open-raise even from the button in three-handed play, so folding preserves chips.

Cheap price to see a flop heads-up against the big blind with a weak but live hand; folding here is unnecessary given the small additional cost.

K2o is marginal; checking in position as BB with a limped pot keeps the pot small and avoids bloating with a weak kicker.

I have an open-ended straight draw (needs K or 9) on a coordinated board, so a half-pot semi-bluff bet applies pressure and builds equity for the draw.

K-high with no draw on T-Q-4 board facing a flop bet; folding is cheapest option.

7-3 offsuit is a trash hand on the button facing a raise-worthy pot; folding is standard preflop discipline.

Heads-up with ace-high vs a random BB hand is a clear raise; take the initiative and apply pressure.

K8o has enough equity and position against a likely wide small-blind raise, and calling 200 into 400 is a better price than folding or bloating the pot with a 3-bet.

I have a gutshot (J or K gives straight) plus overcard, but no showdown value now; checking keeps the pot small with a weak ace-high draw heads-up.

King-high with no pair or draw on T-9-Q; checking is free and avoids bloating the pot with air against the preflop raiser.

I have ace-high with a gutshot-ish draw (need a J or K for straight actually only J gives KQJT? no—A2 with T9Q board gives no made hand). Checking is free; I can fold to a bet or take a free card.

King-high with no pair or draw has little bluff equity, and both players have checked to the turn. Checking realizes the occasional showdown win against equally weak hands.

I only hold a pair of twos with an ace kicker, which is unlikely to be ahead if I bet and too weak to value-raise; checking keeps the pot cheap and gives a chance my pair holds at showdown.

I have top pair with a weak kicker on a straight-heavy board, and the opponent has checked every street. Checking realizes showdown value without betting into a range that mostly continues with better hands.

In a 3-handed game the button opening range is wide, and J9o has decent playability in position. A min-raise pressures the blinds and takes initiative cheaply.

Pocket sevens is ahead of a button open in three-handed play, so I three-bet to 650 to take the initiative and deny equity rather than flat out of position.

4-2 offsuit facing a raise and reraise is a clear fold.

J9 offsuit is far too weak to call a 3-bet out of position; folding loses only 450 chips versus a dominated spot.

On the button in three-handed, A2o is a standard open. A 2.5bb raise takes the initiative and can win the blinds uncontested.

Weak offsuit low cards facing a raise; not worth defending from the small blind.

J4 offsuit is far too weak to defend against a button min-raise out of position, with dominated kicker risk on all postflop streets. Folding preserves chips for better spots.

Button raise with a decent King-high hand to isolate and take advantage of position against two limpers/blinds.

Queen-two offsuit is dominated by the button's 2.5x opening range and plays poorly out of position with no implied odds. Folding and saving 200 chips is the best EV line here.

A4o is too weak to continue out of position against a button open; the ace is dominated and the hand plays poorly postflop.
