Hold'em table

A3o from the button is a reasonable open in a 3-handed game; raising to 250 applies pressure with position advantage.

With Ace-suited and a strong kicker, I'm in a premium position in the small blind. Facing a raise to 250 from seat_1, I'll re-raise to 800 to apply pressure and build the pot with a strong holding while narrowing the field.

6c5s is too weak to continue from the big blind against an open and a large 3-bet, especially out of position.

A3 offsuit is too weak to continue against a 3-bet from the blinds; folding preserves chips.

3-10o is a weak hand from the button facing a raise. Folding preserves chips against uncertain opponents early in the session.

A7 suited is a strong heads-up small-blind opening hand, and raising applies pressure while retaining postflop playability.

Weak offsuit-ish speculative hand (4s8s suited but low), facing a raise with only one opponent left; not worth calling out of position.

Pocket queens are a premium opening hand on the button. I raise for value and to build the pot while retaining postflop position.

4-2 offsuit is a weak hand facing a 3x raise; folding preserves chips for better spots.

4-8 offsuit is a weak hand with poor equity against a 3x raise from the button. Folding preserves chips rather than committing more to a marginal situation.

Weak offsuit hand (9-5) with poor connectivity; not worth investing chips from the button facing a raise-worthy pot.

6-10 offsuit is a weak hand with unfavorable equity against the big blind. Folding avoids putting more chips into a disadvantageous situation preflop.

9-6 offsuit is a weak hand in early position. With the small blind still to act and the big blind already committed, folding avoids putting chips into a marginal situation where I'm likely behind most reasonable hands.

6-high offsuit is far too weak to defend from the small blind against the big blind.

Pocket sixes are a strong button opening hand three-handed. Raising to 3bb builds the pot while retaining initiative.

2-9 offsuit facing a raise from the button is not worth defending from the small blind.

J-5 offsuit is a weak holding facing a 3x raise from the button. With only 100 chips invested as big blind, folding preserves stack and avoids marginal situations out of position.
