Hold'em table

JTo on the button in 3-handed play is well ahead of blind ranges, so raising takes initiative and fold equity.

84 offsuit is too weak to continue against a button open; folding saves chips.

4-9 offsuit is a weak hand with poor playability. Seat 1 raised to 250 from the button, indicating strength. Folding preserves chips against a likely better holding.

Button open with suited 97s in a three-handed pot; a small raise takes the initiative with position rather than flat-calling.

Q7o is a weak hand in 3-handed play, and facing a raise from seat 2 to 250 chips requires calling 200 more with poor card equity. Folding preserves chips for stronger opportunities.

J5 offsuit is too weak to defend the big blind out of position against a button raise; it is dominated by better jacks and has poor realizability postflop.

Q3o is a weak hand in early position after the small blind's raise. With no fold equity and poor equity against most reasonable ranges, folding preserves chips for better opportunities.

Heads-up in the small blind after the button folded, A6o is well ahead of the big blind's wide range and plays better as a raise than a limp. Raising to 300 applies pressure and builds value with ace-high equity.

Nine-deuce offsuit is too weak to continue against a preflop raise, even heads-up from the big blind.

Ace-King on the button in a 3-handed game is a premium open; raising to 3bb builds value and takes initiative.

96o 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, poorly connected hand.

9-6 offsuit is a weak hand. Facing a 300 chip raise to 200 more, folding is the prudent play against an aggressive opponent who has already invested significant chips.

76s is a playable suited connector on the button in a three-handed game, so I open to 2.5bb to take the initiative rather than flat the big blind.

AJ is a strong hand that plays well against a single opponent's aggression. Raising to 800 builds the pot while having fold equity and a strong hand to continue with postflop, while still keeping the pot manageable given the 10k stack depth.

7-5 offsuit is very weak facing a button open and a small-blind 3-bet to 800; calling 700 out of position has poor equity and implied odds.

76s has enough playability in position against a single 3-bettor to continue; calling 550 into 1150 is preferable to folding or bloating the pot with a 4-bet.

I have Jack-Ace of different suits with a paired board (6-6-Q). This is a weak hand with limited potential in a heads-up flop situation. Checking allows me to see the next card inexpensively while keeping the pot manageable. My opponent has shown strength with their 3-bet, so checking gives me information without committing more chips to a marginal hand.

I flopped trip sixes and the opponent checked, so I bet about 60% pot for value while keeping weaker queens and draws in.

9-5 offsuit is a weak hand in early position. With a small blind and big blind already in, calling 100 chips costs 1% of stack but has poor equity against likely holdings. Folding preserves chips for stronger opportunities.

27 suited is weak but heads-up against an unchecked big blind, calling 50 into 150 needs only 25% equity which this suited hand has, and folding would surrender the small blind.

Heads-up with A8o against a small-blind complete, a small raise takes the dead money often and builds a pot when called by worse aces and broadways.

2-7 suited is very weak facing a big blind raise to 3.5bb after my limp, and I would be out of position postflop needing too much equity to call 250 more.
