Hold'em table

On the button three-handed, K2 offsuit is playable as a small opening raise, using position to realize its equity.

5-3 offsuit is a weak hand out of position against a button raise with the big blind still to act, so folding is best.

T5s is too weak to defend out of position against a 2.5bb button raise despite getting decent pot odds.

T6 suited on the button in a 3-handed pot has decent playability and getting 150 to 100 odds, so a cheap call is reasonable rather than folding or bloating the pot.

Completing from the small blind with suited one-gapper J8s getting 5:1 pot odds facing a button limp.

Pocket sevens are strong enough to raise against two limpers. Raising to 500 builds the pot and may narrow the field while I’m out of position.

T6s is weak against a big blind 5x raise, with the small blind still to act behind me. Calling 400 to see a flop out of position against a likely strong range isn't worth it, so I fold.

Facing a 5bb squeeze from the big blind while out of position, J8s does not have enough equity or playability to justify calling 400 more chips.

J4s is slightly too weak to open profitably from the button even three-handed, so folding is the standard play.

With the button folded, calling the extra 50 chips is inexpensive heads-up. I prefer a limp to raising with 8-4 offsuit.

Ace-x suited-ish (A2 offsuit) is a strong hand heads-up against a limping small blind; raising for value and initiative in position-disadvantaged spot is reasonable.Sizing 4bb builds pot.Fold equity vs. limp range is good.Ace blocker helps too.Simple aggressive line.

8-4 offsuit is too weak to call a large preflop raise out of position.

T9 offsuit is strong enough to open on the button three-handed, and a 2.5 big blind raise keeps the sizing efficient.

AKo is a premium hand in 3-handed play. A 3-bet from the small blind against a button open builds the pot and takes the initiative, with the big blind still to act behind me.

85o is an unplayable hand facing an open raise and a 3-bet.

T9 offsuit is too weak to call this sizable three-bet, even with position.

Q7 offsuit is a weak hand out of position postflop against two opponents, so folding on the button for 100 to call is the safer play.

J5s is well within standard SB opening range when folded to in blind-vs-blind. Raising to 2.5bb puts pressure on the big blind while retaining the initiative.

A-Q suited is strong heads-up against a small-blind open. A three-bet builds the pot for value while retaining position after the flop.

J5s is too weak to call a 3-bet out of position.

Q6o is too weak to profitably open from the button, even in 3-handed play.

J5 suited is playable heads-up against the big blind. A small raise can win the pot now while keeping the investment modest.

Q3 suited is weak; calling 150 more out of position against a small blind's 2.5x raise with a marginal hand is a slight loser, so folding is reasonable.
