Hold'em table

I'm on the button with pocket threes; raising to 3x isolates the blinds and builds a pot while retaining set-mining value.

8-4 offsuit is a weak hand out of position in the small blind facing a 3x button raise, with the big blind still to act behind. Folding is clearly best.

Holding Ac5c in the big blind against a button open gives excellent playability and pot odds of 200 to win 450, comfortably warranting a call to close the action.

I check to the preflop aggressor out of position with top pair and a weak kicker to control the pot.

Pocket threes have little value on an A-J-9 board; checking back avoids bloating the pot with a weak holding.

I have top pair with a weak kicker on a coordinated board with three hearts. Checking controls the pot size and allows me to evaluate on the river.

Pocket threes with no made hand or draw on a flush-heavy board; checking behind to control pot size and see the river cheaply.

I hold top pair with board kickers (pair of Aces, K-J-9). Checking to realize showdown value as betting rarely gets called by worse hands.

My pocket threes don't improve on this board; no value in betting a weak hand into a checked river.

9-6 offsuit is a weak hand, and acting first from the button against two players still to act makes a call unprofitable. Folding costs nothing.

In a blind-versus-blind confrontation, J8s is comfortably within the standard opening range, so raising to 3bb applies pressure and builds the pot with good playability.

3h2h is a weak offsuit-adjacent low suited connector but facing a raise heads-up with poor equity; folding preserves chips given marginal hand strength.

J8o is slightly too weak to open profitably from the button even in 3-handed play.

Heads-up pot with A6o from SB after button folded; raising to build pot and apply pressure on BB.

4-9 suited is a weak hand, and calling 200 more out of position against a small blind raise to 3bb (a wide range) is marginal. Folding is simplest and costs only the 1bb already posted.

96o offsuit from the button facing a raise-less limp situation is weak; folding is standard given marginal equity and no fold equity consideration needed here.

The button folded, so this is heads-up against the big blind. A6o is a decent hand with an ace blocker, so I'm raising to 3bb for value and initiative rather than completing the small blind.

Facing a 3bb open from the small blind, J4s is slightly too weak to defend profitably despite having position.

A6 suited on the button in a 3-handed game is a strong enough hand to open. Raising to 3bb applies pressure on the blinds and builds a pot with position.

Folding QJo from the small blind facing a 3x button open, as it plays poorly out of position with the big blind left to act.

3h5d offsuit is a weak hand facing a raise from the button; not worth calling out of position.

54 offsuit is too weak to open from the button even in 3-handed play.

9-4 offsuit is weak; folding to avoid investing more with a poor hand heads-up against the big blind.
