Hold'em table

K4o on the button in 3-handed play is a standard open; a 2.5bb raise steals the blinds often and keeps position postflop.

4s2s is far too weak to defend the small blind against an early 2.5bb open with the big blind still behind.

9-5 offsuit is too weak to defend out of position against a 2.5 big blind raise.

Q9 suited has decent button equity three-handed and can profitably open-raise to pressure the blinds.

K8 suited is strong enough to contest a button open three-handed. Reraising gives me a chance to win preflop or play heads-up with the initiative.

Pocket threes facing an open and a 3-bet, with the opener still left to act, is a clear fold. Calling 800 out of position to set-mine gives poor implied odds and leaves me open to a squeeze from the button.

Q9 offsuit is too weak to continue against a large small-blind 3-bet after opening, especially with deep stacks.

KTo is a profitable button open three-handed. Raising to 2.5 big blinds applies pressure while keeping the pot manageable.

A2 offsuit in the small blind against a button open plays poorly out of position as a call, so I'm choosing between 3-betting and folding. The ace blocker makes it a reasonable 3-bet bluff against a wide button range, and it keeps the big blind from coming along.

7-high suited is far too weak to continue facing a raise and a large 3-bet from the big blind.

KTo is easily dominated by a small-blind three-bet range. Calling 750 chips risks difficult postflop decisions, so I fold.

Pocket fours on the button in 3-handed play is a clear open-raise; 2.5bb puts pressure on the blinds.

9-4 offsuit is too weak to defend the small blind against a button raise in a three-handed game, especially with the big blind still to act.

T5 offsuit is too weak to defend profitably against a 2.5 big blind button raise at this stack depth.

Q4 suited is a reasonable button steal in a three-handed game, using a modest open size to pressure the blinds while keeping risk controlled.

T9 suited plays well against a wide button opening range. A 3-bet from the small blind can win the pot now and avoids inviting the big blind in cheaply.

J9o facing a raise and a large 3-bet from the small blind, with the original raiser still to act behind, is a clear fold.

Q4 offsuit is too weak to continue against a large small-blind 3-bet after opening.

T9 offsuit is playable on the button in a three-handed game. A 2.5 big blind raise gives me a chance to win the blinds while retaining position if called.

J3 suited out of the small blind facing a button open, with the big blind still to act, is too weak to call profitably out of position; folding is standard.

K3 offsuit is too weak to defend against a button raise from the big blind, especially out of position.
