Hold'em table

Button opening range can profitably include suited/offsuit aces in a 3-handed game; raising applies pressure and captures blind equity.

A9o in the small blind facing a button open 3-handed is a solid 3-bet candidate; squeezing to 10bb out of position denies the big blind's equity, and the ace blocker helps. Flatting out of position with the BB still to act is worse.

65o is too weak to continue against a raise and reraise preflop, especially out of position with more action possible behind. Folding preserves chips for better spots.

A3 offsuit is too weak to continue facing a large 3-bet, especially out of position postflop.

T3 offsuit is below a reasonable 3-handed button opening range, so folding is the lowest-loss option.

As7s is a strong hand heads-up, and raising puts pressure on the big blind while building the pot when I have equity.

8-high suited has sufficient equity to defend the big blind against a minimum raise heads-up.

I have a gutshot and backdoor flush draw with an overcard, but no made hand yet. Checking keeps the pot small and lets me see a free turn card out of position.

We have an open-ended straight draw with additional backdoor spade potential. Betting applies pressure to missed overcards and builds a pot when we improve.

Queens are a premium hand, so I raise to build the pot and put pressure on the blinds.

4-high suited is far too weak to defend from the small blind against a button 3x open with the big blind still to act.

84o out of position against a 3x button open is too weak to defend profitably, even with the 30% pot odds, because its equity is hard to realize.

9-5 offsuit is too weak to open profitably on the button against two blind defenders.

Blind-vs-blind with T6o is a reasonable open from the SB; raising to 3bb applies fold pressure and avoids playing a weak hand out of position in a limped pot.

I have a small pair and the pot is offering decent odds to call the small raise. I'll try to hit a set on the flop.

Ace-high board favors my preflop raising range, so a small one-third-pot c-bet should fold out many of the big blind's weak hands cheaply. My hand has little showdown value, which makes it a reasonable bluff candidate.

96o is below a sound button opening range three-handed at 100bb, and it would face two blinds that can defend or 3-bet, so I'm folding.

6-3 offsuit is too weak to continue out of position against the big blind, and the extra 50 chips is not worth the reverse implied odds.

Pocket sixes are a solid hand to raise from the button, and a raise to 300 puts pressure on the blinds while keeping the initiative. This should often win the pot preflop or give me a good chance to continue in position.

9-high with a deuce is far too weak to defend from the small blind versus a button raise, especially with the big blind still behind.

J5 offsuit out of position against a 3x button open realizes too little equity to justify calling at 30.8% pot odds, so folding is the marginal but disciplined choice.
