Hold'em table

A6o on the button in a 3-handed game is a standard open; raising to 300 pressures the blinds and gives me position postflop.

5-2 suited is too weak to continue against a button open to 3bb; folding saves chips for better spots.

K7o is playable as a wide button open in three-handed poker, and raising takes the initiative with position rather than limping or folding.

5-2 offsuit is a trash hand facing a raise; folding is clearly correct.

TJo is a playable hand against a button min-raise; calling 150 more keeps the pot small and avoids bloating with a marginal offsuit hand out of position.

Heads-up with an open-ended straight draw (8 or K completes it), I can semi-bluff the Q-high flop for fold equity while building a pot when I hit. A small bet keeps the pot manageable if raised.

King-high with no pair and only a backdoor club has too little equity to continue against a 350 flop bet.

Ace-high with a decent kicker on the button; raising to isolate and take advantage of position.

2-6 offsuit is far too weak to call 250 more into a 3x raise, especially with the big blind still to act behind me. Folding preserves chips for better spots.

Q4 offsuit is too weak to continue against a button open after the small blind folds, so folding avoids a dominated spot out of position.

T5s is a suited, playable hand and I have position on both opponents in 3-handed play, so a standard 3x button open puts pressure on the blinds while retaining fold equity and flush potential.

84 offsuit is too weak to continue against a button open, especially out of position with the big blind still to act. Folding avoids putting more chips in with a dominated, low-equity hand.

63 offsuit is a weak hand facing a raise; folding is correct here.

42 suited is too weak to open from the button for 100 chips; folding preserves my stack with no investment.

Button folded, heads-up vs BB with Ax offsuit; raise to build pot and take initiative.

5s2h offsuit is one of the worst hands in hold'em; calling 200 more out of position against a small-blind raise has poor implied odds and no way to profit postflop. Folding is clearly best.

7c Th is a weak offsuit hand not worth playing from the button facing action; folding preserves chips.

Queen-five offsuit is too weak to play from the SB against the BB even heads-up; folding avoids playing a dominated marginal hand out of position.
