Hold'em table

Q8o is a weak hand in early position with a 100 chip cost to call. Folding is the correct play—this hand doesn't have sufficient equity to justify investing further in a three-handed game.

AJs is a strong heads-up blind-versus-blind hand and should raise for value and initiative.

6d Ts offsuit is weak against a raise from the small blind after button folded; folding avoids committing chips with a marginal hand.

Q7 offsuit is a reasonable button opening hand three-handed, leveraging position and initiative.

Qc6d is a weak offsuit hand facing a raise from the button with a player still to act behind; not worth continuing.

Holding Ah-Td (ace-high with broadway potential), this is a strong hand worth re-raising. Raising to 700 represents good odds relative to the pot and applies pressure to seat_2's 250-chip raise, while avoiding excessive commitment preflop.

Q7 offsuit is too weak to continue against a substantial 3-bet out of position-effective heads-up ranges, especially after opening small. Folding preserves chips.

Qs6d offsuit is weak from the button facing a raise-like blind structure with no equity edge; folding preserves chips.

6h7h is a weak hand in the small blind facing a big blind. With only 50 more chips to call against a 100-chip big blind, and no premium holding, folding is the prudent play to preserve chips.

2-10 offsuit is a weak hand in early position with no competitive advantage against the big blind and small blind. Folding avoids playing a marginal hand out of position.

With the button folded, 9-8 offsuit is strong enough to apply pressure heads-up from the small blind. Raising builds initiative and can take down the blind immediately.

T4 offsuit is too weak to open profitably from the button in this format.

Heads-up after button fold, Q7 suited is playable; raising to build pot and take initiative against lone BB.

T2o is a weak hand with no high card strength or discounted straight potential. Facing a 3x raise from the small blind after folding the button, folding is the clear optimal play to preserve chips.

J5 offsuit-ish (Js5s is suited, but weak kicker/low connectivity) from the button facing a raise-less pot is marginal; folding preserves stack for better spots given no antes and full stacks.

T2o is a weak hand with poor connectivity and low card values. Against the big blind's raise, folding preserves chips when holding such a marginal holding from the small blind position.
