Hold'em table

Ace-x on the button is a reasonable opening hand for a standard raise to build the pot and take initiative in 3-handed play.

A9 offsuit is a strong enough blind-versus-button hand to 3-bet for value and leverage the ace blocker. The larger out-of-position sizing pressures a wide button opening range.

6-5 offsuit is a weak hand facing aggressive preflop action (a raise to 250 from button and a 3-bet to 900 from small blind). I'm out of position as big blind with poor equity against this range, making a fold the optimal play to preserve chips.

A3 offsuit is too weak to continue against a large 3-bet; folding preserves chips for better spots.

T3 offsuit is too weak to open profitably on the button in this format.

A7s is a strong hand in 3-player preflop situations. With seat_2 folded and only seat_1 (big blind) remaining, raising to 200 (min raise) applies pressure and builds the pot with a solid holding while keeping stack management efficient.

84 offsuit facing a raise heads-up with only one opponent to act is not worth defending; folding preserves chips.

Queen-queen is a premium hand that plays well heads-up or three-way. Raising to 600 chips (6BB) applies pressure while building the pot with a strong hand from the button position.

4-2 offsuit is weak; facing a 6bb raise with a bad kicker hand, folding is correct.

8-4 offsuit is far too weak to defend against a 6bb button open out of position.

9-5 offsuit is a weak hand not worth defending from the button against two players; folding preserves chips.

With the button folded, T6 offsuit is strong enough to apply pressure heads-up from the small blind. A standard raise can take down the blind or play a manageable pot.

9-6 offsuit is too weak to profitably open against two blinds, particularly with poor playability and domination risk.

6-3 offsuit is a weak hand in the small blind, and I've already invested the small blind. With only the big blind remaining to call and seat 2 folded, folding is the correct decision against the big blind's strong positional advantage.

Pocket sixes is a reasonable hand from the button. Raising to 600 (6BB) puts pressure on the blinds, builds the pot, and allows me to take down chips preflop or play profitably in position postflop.

2-9 offsuit facing a 6bb raise is far too weak to continue profitably.

J5 offsuit is too weak to defend against a 6bb button open out of position, especially with the small blind already folded.
