Hold'em table

Pocket fours on the button in 3-handed play is ahead of typical ranges; raising builds value and takes initiative over calling.

QTo offsuit is too weak to continue out of position against a button raise, especially with the big blind still to act.

J4 offsuit is weak and facing a raise with a player still to act behind; folding is correct.

K5 offsuit is too weak and easily dominated to open from the button, so I fold rather than inflate the pot.

Weak offsuit low cards (4d6c) heads-up vs BB with no equity advantage; folding is cheap here.

Offsuit 6-10 from the button facing a raise-and-call situation isn't strong enough to play profitably; folding preserves chips.

6-9 offsuit is a weak, disconnected hand and I would be out of position against the big blind for the rest of the hand, so completing is not worth it.

J3 offsuit is too weak to call or raise from the button in 3-handed play against the blinds; folding preserves stack.

Button folded, so this is heads-up versus the big blind with KQs. A raise to 3bb builds the pot with a strong suited hand and denies a free flop.

J6o is a weak hand facing a 3bb raise from the small blind; folding is correct from the big blind with no equity to defend profitably.

On the button in three-handed play, K7o is a reasonable steal open against the blinds. A 2.5bb raise pressures both blinds while keeping the pot manageable if called.

KJ offsuit is strong heads-up-ish in a 3-handed pot; 3-betting the button's open builds the pot with a hand that plays well and applies pressure.

4-2 offsuit is one of the weakest hands and faces a raise and 3-bet for 600 more; folding preserves the stack.

K7 offsuit is too weak to continue against a 3-bet; calling 450 more is not justified.

Weak offsuit-ish low card combo (T3s) from the button facing a raise-free limp pot isn't worth it; fold to preserve chips since hand is marginal and not worth investing from a non-premium spot.

Button folded, so this is a SB vs BB steal spot. Q7o has good equity heads-up and raising applies fold pressure while building a pot with a playable hand.

T4 offsuit is too weak to continue against a preflop raise, especially out of position. Folding avoids putting more chips in with a dominated, unconnected hand.
