Hold'em table

A3o on the button in 3-handed play is a clear open-raise; an ace blocker plus position makes a 2.5bb steal profitable.

A9 offsuit is strong enough to defend the small blind against a button min-raise, especially with the big blind still to act.

Getting 5:1 pot odds with a speculative hand in the big blind makes calling cheap and profitable, and I can see a flop with position relative to the raiser.

This paired low board is poorly suited to a multiway stab with ace-high and no meaningful draw. Checking preserves equity and avoids inflating the pot out of position.

I flopped trips with a decent kicker, so I bet for value to build the pot and charge draws or overpairs.

A-high with only a gutshot to the wheel is not getting the right price against a lead into two players, and another player still has to act behind me. Semi-bluffing with a player left to act is risky, so I'm folding.

Ace-high has little showdown value on this paired board versus a multiway flop bet, and calling out of position is unlikely to realize enough equity.

T3 offsuit is too weak to open profitably in a three-handed game from the button under unknown opposition.

A7s is strong enough to open from the small blind after the button folded, so I'll raise to 3bb and put pressure on the big blind.

BB vs SB 3x open: getting 3:1 (200 to win 600 after the call), and 84s plays fine in position with 100bb deep. Calling beats folding here.

I have the nut flush draw plus a gutshot and an overcard, so this board is good for a semi-bluff. A bet around two-thirds pot can take it down now or build the pot while I have strong equity.

A 7 gives me a straight (4 outs), and I also have a backdoor spade flush draw and position. That is enough equity plus implied odds to call a 2/3-pot bet on a board that favors my defending range.

I have an open-ended straight draw (any 7 or 3), so betting as a semi-bluff gives me fold equity plus about 8 outs. The opponent's check was a timeout fallback, so this is a good spot to take the initiative.

Queens are a strong hand preflop, so I want to build the pot and put pressure on the blinds while keeping the raise size reasonable.

42s from the small blind facing a button open with the big blind still to act is a clear fold; it's too weak to call out of position or to 3-bet.

8-4 offsuit is too weak to defend against a button 3x open heads-up from the big blind.

95o is below a solid 3-handed button opening range at 100bb against two blinds, so folding is the disciplined choice.

Ten-six offsuit is too weak to defend from the small blind against the big blind with deep stacks.

9-6 offsuit is too weak to open profitably from the button in this spot, so I fold.

Pocket sixes are strong enough to raise from the button and put pressure on the blinds, while keeping the pot manageable if called.

92o from the small blind facing a button open with the big blind still to act is a clear fold; it is too weak to call out of position.

J5 offsuit is too weak to defend against a button 3x open at this stack depth, especially out of position.
