Hold'em table

A3 offsuit is too weak to open profitably from the button in this short-stacked three-handed setup.

With Ace-Nine suited from the small blind after the button folded, raising to 300 (3x big blind) is a standard play to build the pot and apply pressure to the big blind. This is a reasonable opening raise with a decent hand that has both high card and flush potential.

6-5 offsuit facing a 3bb raise from the small blind is not worth defending; fold and preserve chips.

3-10o is a weak hand in a 3-player game from the button. Folding avoids investing chips into a marginal spot where I'm out of position post-flop.

A7 suited plays well heads-up against only the big blind; raising to build pot and apply pressure after the button folded.

Suited 8-4 has sufficient equity and playability to defend getting 3:1, especially with position postflop.

I hold a flush draw with an overcard on a dry board; a continuation bet applies pressure while retaining strong equity if called.

I have an open-ended straight draw and sufficient implied odds against the modest continuation bet.

I have complete air (A-high, no pair, no draw) and my opponent has called two streets already, suggesting real equity; better to check and control the pot than fire a third bluff.

With only a gutshot straight draw and no made hand, checking preserves equity and avoids inflating the pot after the opponent checked.

I have only ace-high with no pair or draw, so betting the river offers no value against a calling range; check to see showdown for free.

My eight-high has little showdown value against the opponent's likely missed overcards. Their turn and river checks after c-betting create a plausible opportunity to bluff them off unpaired hands.

I only have ace-high with no pair, no flush, and no draw; facing a river bet I have essentially no showdown value, so folding is correct.

QQ is a premium hand; raise to build the pot and isolate from the button position.

4s2s is far too weak to defend from the small blind versus a button 3x open, especially with the big blind still behind.

4-8 offsuit is a weak hand in a 3-handed game, and facing a 3x raise from the button after already committing the big blind, folding is the correct play to preserve chips.

9-5 offsuit is too weak to open from the button under standard short-handed ranges.

6-Tc is a weak holding with no high cards or strong potential. With only 50 chips to call (already invested as small blind), folding minimizes losses against the big blind in a 3-player game where position is unfavorable.

9-6 offsuit is a weak hand in early position. With blinds to my left and only a 100 chip call, folding preserves chips for stronger opportunities while minimizing expected losses from a dominated position.

6-3 offsuit is weak, button folded, and facing a call versus only the big blind heads-up isn't profitable with such a poor hand.

Pocket pair 66 on the button; raising to 3.5bb builds the pot with a hand that plays well against two limpers/blinds and can win outright or set-mine.

9-high offsuit is far too weak to defend from the small blind against a button open, especially with the big blind still behind.

J5o is a weak hand out of position facing a 3.5x raise from the button. With limited equity against a strong raising range and poor post-flop playability, folding preserves chips for better opportunities.
