Hold'em table

T6o is weak, but with button position and no action yet, a raise can take down the blinds or isolate with position.

JTs is a strong, playable hand versus a button open and benefits from denying the big blind an easy entry. A sizable small-blind 3-bet takes initiative despite being out of position.

K4o is a weak hand, and facing a 3-bet to 1100 chips from seat_2 after seat_1's initial raise, the odds and position do not justify calling with this marginal holding. Folding preserves chips for stronger spots.

T6o is too weak to continue against a sizable small-blind 3-bet; calling 800 with a dominated offsuit hand is not profitable.

T7 suited is a marginal button open in this format, and folding avoids playing a weak, dominated hand from a reset stack.

T-J offsuit is a marginal hand, but I'm in the small blind facing only the big blind since seat_2 folded. Raising to 200 (min-raise) applies pressure and gives me better value if my hand is best, while folding would waste my small blind investment.

9-2 offsuit is too weak to defend against a small blind raise even with 3:1 pot odds, so folding preserves chips.

3d-Qh is a weak hand (Queen-high with a 3 kicker). Folding from the button against an active small blind and big blind is standard; this hand lacks the strength to profitably contest the pot.

With 9d5c out of position against the big blind, the hand is too weak to continue. Folding avoids risking additional chips with a marginal holding.

Q5s is playable on the button in a 3-handed game; a 2.5bb raise pressures the blinds and gives me initiative.

AJo is strong enough to 3-bet for value against a button open in this short-handed configuration, applying pressure while retaining initiative.

4-3o is a weak hand that doesn't warrant calling 800 chips facing a 3-bet in an early position. Folding preserves chips for better spots.

Q5s is too weak to continue against a sizable small-blind 3-bet, especially with the big blind already folded and poor playability postflop. Folding avoids putting more chips in with a dominated hand.

7-5 offsuit is too weak to open profitably from the button against two blinds, so I fold.

J4o is a weak hand from the small blind. With seat_2 folded and seat_1 (big blind) showing strength with a 100-chip bet, folding saves chips and avoids playing a marginal hand out of position.

QTo is a strong enough hand to raise heads-up against the big blind after the button folded. Raising takes initiative and can win the pot immediately or build value when called.

9-3 offsuit is far too weak to defend against a small-blind raise heads-up out of position.
