Hold'em table

On the button with a suited king, a standard open raise sized 2.5x BB is appropriate in this 3-handed spot to leverage positional advantage.

J5o is too weak to continue out of position against a button open; folding saves chips.

Seat 1 raised to 250 and seat 2 folded, leaving me to call 150 more. With Jc6c on the button, the pot odds don't justify continuing against a raise from the button, so I'll fold to preserve my stack.

J2o is too weak to open even from the button in three-handed play; folding avoids putting chips in with a dominated offsuit hand.

4d3d is a weak hand to play from the small blind facing a big blind raise, and the big blind has a significant range advantage. Folding preserves my stack for better spots.

Calling the big blind with 6-7 suited on the button is a standard play to see a flop cheaply and potentially realize implied odds. The pot is already 150, so I'm getting good odds to continue.

Pocket nines is a strong hand preflop; raising for value builds the pot against limpers and defines my range.

Q7 offsuit is too weak to call a raise to 400 after a limp; folding avoids playing a dominated hand out of position.

6s7d is a speculative hand that can play well postflop; calling keeps my stack flexible and lets me see a cheap flop against a single raiser.

My pocket nines are now an underpair to both the jack and ten on this flop, so I'll check to control pot size and see how seat_3 reacts.

I have a 6-7 double gutter on a 4-J-T flop with no pair, so I want to keep the pot small and see a turn card without putting more chips in. Checking also preserves my stack and avoids building a big pot with a marginal draw.

With an underpair to the board and no clear improvement, I'll take a free card and control the pot size.

Board is coordinated with a straight draw and flush possibilities; my 6-7 gutshot is weak, and checking lets me control pot size and see the river cheaply.

Pocket nines missed the board's top pairs; with both opponents checking every street, this looks like a showdown spot rather than a bluff opportunity.

The board is uncoordinated and my 6-7 doesn't improve on the river, so I have no reason to build a bigger pot. Checking lets me see a cheap showdown and potentially win with high card or a missed straight draw.

KJ offsuit on the button is a decent hand to raise for value and take initiative against two opponents.

ATo is strong enough three-handed to 3-bet the button open for value and fold equity before the big blind acts.

With Qd5h on the button facing a 800 raise, I have no pair, no suitedness, and poor postflop playability, so folding is the correct play to preserve my stack.

T2 offsuit is too weak to open even on the button, so folding avoids putting chips in with a dominated, disconnected hand.

I have 10-high offsuit, which is too weak to continue against the big blind's 100-chip raise. Folding preserves my stack for better spots.

I have 2c Kd, a weak offsuit hand with no pair and poor equity. Facing a 100 big blind raise with only a backdoor flush draw, folding is the correct play to preserve my stack.

Heads-up with Ace-high, a standard raise to build the pot and take initiative against the big blind.

K6o is too weak and often dominated against a 3x small-blind open; the price does not justify defending out of position postflop realization issues.
