Hold'em table

K5 offsuit is a weak hand from the button facing a raise to 100; folding preserves chips for better spots.

Q4 offsuit is a weak small-blind holding against the big blind, and completing offers poor equity realization out of position.

Raise the button with A6 suited to leverage position and initiative against the blinds.

58o is weak facing a 3bb raise from the button; not worth calling out of position with a poor hand.

6-10 offsuit is a weak hand out of position on the button. With no reads on opponents yet and limited information, folding preserves chips for stronger hands. The risk-reward doesn't justify calling 100 chips with this marginal holding.

Heads-up pot with Q9o is playable; raising to build pot and take initiative against BB.

9-6 offsuit is too weak to defend against a small-blind raise heads-up from the big blind.

Button with weak offsuit 6-7, facing a raise-like blind structure in 3-handed; folding is fine since it's an unraised pot I could limp, but 67o is marginal from button vs two live blinds, so folding preserves equity.

A2 offsuit is a strong heads-up holding after the button folds. Raising applies pressure and retains initiative against the big blind.

Q9o is a weak hand preflop, and facing a 3x raise from the small blind, folding is the optimal play to preserve chips. With no premium holdings and poor equity against a raising range, this is a straightforward fold.

Q8 offsuit is a reasonable button opening hand three-handed, and raising applies pressure to the blinds while retaining positional advantage.

9-8 offsuit is a weak hand out of position facing a raise to 250 chips from the button. The risk-reward is poor, and folding preserves chips for stronger situations.

2d6c is a weak offsuit hand with no connectivity; facing a raise, folding is correct.

King-Five offsuit is a modest hand, but raising from the button provides positional advantage and allows me to play with initiative. This is a standard raise size that applies pressure while keeping my stack protected.

T6 suited is too weak to continue against a 4x open out of position with BB still to act.

7-high with a weak kicker is far too weak to defend against a 4bb button open out of position.
