Hold'em table

K3o is a weak hand out of position (button, with two opponents already having invested). Folding preserves chips for better opportunities, as K3 has poor equity and limited upside.

J5 offsuit is a weak hand heads-up against BB with no fold equity; folding is cheaper than calling with a poor holding.

J2 offsuit is a weak hand not worth playing from the button facing a raise, better to fold and wait for a stronger spot.

Fold the very weak 4-high suited hand from the small blind versus the big blind rather than invest further out of position.

Open-raising suited? Actually 7-6 offsuit is still a playable button steal in a three-handed unopened pot, leveraging position.

Q7 offsuit is weak facing a button raise with a call from BB already priced poorly; folding avoids a marginal spot out of position.

Jack-King suited is a strong preflop hand that plays well in position. Raising to 3x the big blind builds the pot and puts pressure on opponents while allowing me to play profitably post-flop with good equity and position.

ATo is strong enough to 3-bet from the small blind against a single button raise in a 3-handed game, applying pressure and building the pot with a good hand.

Q5 offsuit is far too weak to continue versus a large preflop 3-bet out of position.

Jack-King offsuit is a marginal hand facing a 3-bet to 900 chips from the small blind. With 600 chips to call and a weakly connected hand, folding preserves chips and avoids a difficult decision with significant stack variance in early streets.

T2 offsuit is a weak hand out of position relative to two live players; folding preflop preserves chips.

Complete the small blind getting excellent pot odds heads-up; T4 offsuit has sufficient equity versus a potentially wide big-blind range.

Ace-Ten offsuit is a strong hand in 3-handed play. I'm in the big blind facing one caller, so a 3x raise to 400 chips gains value while allowing me to maintain initiative with this premium holding.

T4 offsuit is far too weak to continue versus a 4bb raise out of position in a heads-up pot.

K2 offsuit is a weak button holding and not worth entering against two blinds at this stack depth.

With Ace-Six suited in the small blind after the button folds, I have a reasonable hand to play. Raising to 300 (3x the big blind) applies pressure to the big blind and builds the pot while maintaining aggression from position.
