Hold'em table

Pocket threes on the button in a 3-handed game is a strong enough hand to open-raise for value and position; a 3x raise puts pressure on the blinds.

8-4 offsuit is a weak hand facing a raise, not worth continuing from the small blind.

A5s has excellent blocker value and postflop playability, making it an ideal candidate to 3-bet bluff from the big blind against a button open.

Pocket 3s facing a BB 3-bet to 1000 after my 300 open: calling 700 to win a 1350 pot gives good odds (about 2.9 to 1) and I have position and set-mining value, while 4-betting would risk too much with a weak pair.

Top pair with a weak kicker on a dynamic flop works well as a check to control the pot size out of position and protect our checking range.

Pocket threes are a weak showdown-value hand on an A-9-J board facing a 3-bet preflop caller who checked. Checking back controls the pot and keeps showdown value, since betting would mostly get called or raised by better hands.

We have top pair with a weak kicker on a wet three-flush board. Checking controls the pot size and keeps the opponent's weaker range in play.

I hold a pocket pair of threes, which is a weak showdown hand on a board of 9h Ah Jd 6h with a possible flush draw and overcards. The big blind 3-bet preflop and then checked twice, so they may be trapping or holding a draw. Checking behind keeps the pot small and gives me a chance to see a cheap river.

I have top pair with a weak kicker on a coordinated board; checking allows me to realize showdown value against missed draws and weaker pairs.

The opponent 3-bet preflop and then checked every street, but my pair of threes is a weak showdown hand against overcards on a board of 9 A J 6 K. Checking behind realizes whatever showdown value it has, and a bluff would fold out only worse hands while losing to better ones.

9-6 offsuit is a weak hand from the button facing a full bet with two players left to act; not worth continuing.

J8s is well ahead of random hands in blind-versus-blind play; raising to 300 exerts pressure and takes initiative.

32s is the worst-tier hand; calling 200 more to win a 400 pot out of position against a small blind raise is not profitable, so I fold.

J8o is on the weaker fringe of 3-handed button opening ranges, making fold a disciplined and standard choice.

Button folded, so I'm heads-up in the small blind against the big blind. A6s is a strong enough hand to raise for value and to take the initiative, so I raise to 3bb.

Weak offsuit-ish hand (4d9d is suited but low connectivity) facing a 3bb raise with only two players left; not worth defending given poor equity and implied odds.

9-6 offsuit is a weak hand, and calling or raising out of position against two players is not profitable. Folding on the button costs nothing, so I wait for a better spot.

Heads-up vs BB with Ace-high offsuit; raising to isolate and build pot with positional/range advantage.

J4s is too weak to defend profitably against a 3x open from the small blind.

Suited ace on the button in a 3-handed pot is a solid raising hand; raise to 300 to build the pot and take initiative.

QJo is weak out of position against a 3x button open with the big blind still to act, making folding standard.

3h5d is a weak offsuit hand. The button raised to 300 and I would have to call 200 more out of position with a pot of 450, so I'm folding and giving up my 100 big blind.

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

9-4 offsuit is a weak hand. Out of position against the big blind, I'd have to call 50 more to see a flop, and the hand rarely plays well enough to justify it, so I fold.
