Hold'em table

Open-raise the button with a king-high hand to capitalize on position and the blinds' wide folding ranges.

5h3c offsuit is a weak hand facing a raise; folding is correct from the small blind.

T5o is a weak hand with poor playability. Facing a 2.5x raise from seat_1 with seat_2 folded, calling 150 more chips is unprofitable against a likely stronger range. Folding preserves chips for better opportunities.

Opening from the button with a suited hand; raising applies pressure to the blinds who may fold, and T6s has some equity if called.

Jack-eight suited is a marginal hand facing a raise from the button. With 200 chips to call and the big blind still behind me, this is not a strong enough holding to commit more chips, especially against an aggressive raiser.

Pocket sevens is well ahead of a typical button opening range heads-up. I 3-bet for value and to deny overcard equity.

T6s facing a 3-bet with weak equity and no position advantage; folding is cheapest option.

4c-Jc is a weak hand in late position. Facing a 100-chip call with no immediate hand strength and unfavorable odds against likely better holdings from the small blind and big blind, folding preserves chips for stronger opportunities.

8-4 offsuit is too weak to defend from the small blind against the big blind at this stack depth.

T9 suited is a strong button opening hand in three-handed play. Raising builds the pot with a hand that has good equity and playability.

AK is a premium hand; 3-betting from the small blind builds the pot and isolates against a min-raise button.

8-5 offsuit is a weak hand in early position facing significant aggression. With seat_1 raising to 250 and seat_2 re-raising to 900, folding is the strongest play to preserve chips and avoid a marginal situation against two aggressive opponents.

T9 offsuit is not strong enough to continue profitably versus a large 3-bet out of position to the small blind.

Qs7d offsuit is a weak hand out of position relative to two live blinds with nothing to gain from a marginal call; folding preserves chips.

Jack-five offsuit is a weak hand in the small blind against a big blind who raised. With only 50 chips already invested and poor hand strength, folding preserves chips for better opportunities.

Q6o is a weak hand with poor showdown value and no premium qualities. Folding preserves chips against a strong positional deficit as the button facing two opponents already invested in the pot.

Complete the small blind with a suited jack in a heads-up pot and realize equity cheaply.

I'm BB with a weak hand (Q3 suited) and can see a free flop since SB just limped; no reason to raise.

This limped pot flop favors the big blind's range, and J-high with only backdoor clubs has limited value. Checking preserves flexibility and avoids bloating the pot out of position.

I have no pair and only a backdoor draw; checking behind is fine since seat_1 already checked and I can see turn for free.

I have only jack-high with a gutshot and little value in building the pot. Checking preserves my showdown chance against missed hands.

I have Q-high with no pair or draw on a paired-ish board; checking is free and avoids risking chips with a weak hand.

Betting the river for thin value with a pair of jacks after the checked-down line; worse ace-high and some weaker pairs may call while we retain initiative.

Board is A-2-T-4-J with three spades possible flush; my Q-high with no pair or draw connection has no showdown value against a river bet, so folding is clearly correct.
