Hold'em table

67o on the button in a 3-handed game has decent playability and gets a good price (100 to win 250), so I'll call rather than fold or bloat the pot with a raise.

With A7o three-handed facing a button limp, an isolation raise to 400 chips leverages our equity advantage and aims to take down the pot or isolate.

A8 offsuit has enough equity to call 300 more from the big blind, and I will have position on the raiser after the flop. Re-raising would risk building a large pot with a hand that can be dominated.

6-7 offsuit on the button is a marginal hand. Calling 300 to win a 900 pot gives 3-to-1 odds, and I'll have position postflop against two opponents, so a call is reasonable. Raising would just build a bigger pot with a weak hand.

In a 3-way pot out of position on a paired king board, checking with Ace-high controls the pot size while retaining decent showdown value.

Ace-high has some showdown value, but betting into two opponents on a paired board is unlikely to get many better hands to fold. Checking keeps the pot manageable.

I have two pair (sixes and kings) on a K-K-6 board, and both opponents checked, so betting for value and protection is reasonable. A bet of about half the pot should get called by weaker kings and sixes.

We hold Ace-high with no draw on a paired flop, multiway out of position with another player behind us facing a half-pot bet.

Ace-high can still be ahead of a button bet after two checks, and the price is reasonable. Calling keeps weaker hands and bluffs in while avoiding an expensive raise out of position.

Ace-high has some showdown value against missed draws, while a turn bet is unlikely to fold out a king or pocket pair. Checking keeps the pot manageable.

I have a pair of sixes with a seven kicker on a K-K-6-4 board, which is likely best or close to it against a checking BB range. Seat_3 checked the turn after calling the flop, so a bet of about half the pot gets value from weaker pairs and folds out overcards or draws.

Ace-high has little chance to improve against a king or a made pair, and the second barrel makes calling 1200 too expensive without a draw.

J4o is too weak to open from the button, even in 3-handed play.

J4 offsuit is playable heads-up against the big blind. A small raise puts pressure on their range without committing too many chips.

8-2 offsuit is the worst hand, and calling 150 to win 350 out of position with poor equity isn't worthwhile against a small blind raise, so I fold.

On the button in a three-handed game, 8-6 offsuit is playable as a small open-raise. Position gives me a chance to win the blinds or navigate a flop.

9-5 offsuit is a weak hand, and I would be out of position against a button raise with the big blind still to act behind me. Calling 175 more is not worth it.

J5o has very poor playability postflop out of position against a button open, making this an easy fold.

KQs on the button in a 3-handed game is a strong hand, so I raise to 3bb for value and to take position and initiative against the blinds.

K2o is a very weak offsuit holding out of position facing an open raise; folding is standard.

Q5 offsuit plays poorly out of position against a 3× button raise, and the price is not attractive enough to defend.

Opening from the button with a pocket pair is standard in 3-handed play.

T6 offsuit plays poorly out of position against a button raise, especially with the big blind still to act.

QTo is a decent hand heads-up in the big blind, getting 350 into 100 (3.5:1) against a button min-raise. Calling is clearly profitable, and a 3-bet with this hand would be marginal.

Top pair with a decent kicker on a fairly dry flop, heads-up and first to act. A small value bet of about half the pot builds the pot and charges worse queens and draws.

We hold an underpair (threes) on a Q-9-2 two-tone board and face a donk bet with negligible equity and poor implied odds.

4-2 offsuit is too weak to profitably play from the button without a specific read on the blinds.

3-7 offsuit is one of the weakest hands. Even heads-up against the big blind, folding for 50 more chips out of position is reasonable, and the sample is small enough that I'm not chasing marginal spots. Actually, the price is only 50 to win 150, so calling is defensible, but playing this hand out of position is a long-term loser.
