Hold'em table

Three-handed button with an ace is a standard open; raising to 300 applies pressure and takes initiative with position.

4-2 offsuit is the weakest starting hand in hold'em. Against an early raise (seat_1 raised to 300 from button) and with the big blind still to act, folding weak hands is standard. The pot odds don't justify calling with such a poor hand.

K5 suited has sufficient equity to defend the big blind heads-up against a button open, especially with the dead small blind in the pot.

I have two pair with a strong kicker on this paired board, and checking lets the preflop raiser continuation-bet while keeping their bluffs in.

As the preflop raiser on a paired board, a continuation bet can fold out worse hands and take down the pot; my ace blocker reduces Qx combos.

We have a strong bluff-catcher/two-pair holding on this paired board and should continue cheaply. Calling keeps weaker c-bets and overcards in while avoiding inflating the pot against queens and full houses.

Our king plays as a strong kicker on the double-paired board, and checking keeps weaker hands and bluffs in while avoiding needlessly inflating the pot.

Ace-high has some showdown value against missed draws, but betting again into a paired board after two check-calls risks being raised by Qx or two-pair hands. Checking controls the pot and lets me reassess the river.

Our two pair is weak on this paired board: any 7, 8, higher pocket pair, or queen has us beaten. Checking realizes showdown value without exposing us to a costly raise.

J7o is a weak hand in early position (button doesn't matter here with 3 players). With a small blind to act after me and big blind already in, folding preserves my stack for better spots.

5-2 offsuit is a very weak hand from the small blind against the big blind, with poor realization out of position. Folding avoids investing further.

T9 offsuit is a playable button opening hand three-handed, and raising applies pressure while retaining positional advantage.

Q3o is a weak offsuit hand out of position against a button raise, and I'm not getting a good enough price to defend. Folding avoids playing a dominated hand in the small blind.

King-two offsuit is a weak holding. Facing a 250 chip raise from the button after already posting the big blind, folding minimizes losses against a stronger range. The risk-reward does not justify calling or raising with this hand.

K7 off-suit is a weak hand from the small blind. With seat_1 already folded and facing a 50-chip call to a 100-chip big blind, this marginal hand has poor equity and should be folded to minimize losses.

Ace-six suited is a reasonable raising hand from the button in 3-handed play. Raising to 300 (3bb) applies pressure, isolates the small blind, and gives me initiative preflop with a decent hand.

K2 offsuit is a weak small-blind holding versus a button raise, with the big blind still behind. Folding avoids defending a dominated hand out of position.

J7o is a weak offsuit hand out of position against a button raise, and the pot odds do not justify continuing with poor playability.

K7 offsuit is a profitable button open in three-handed play and has strong positional value. I raise to apply pressure to the blinds while keeping the pot manageable.

T2o is too weak to continue out of position against a button raise, so I fold and preserve my stack.

3-Jack off-suit is a weak hand, and facing a 250 raise from the button after folding to my big blind, calling 150 more would be speculatively chasing with poor equity. Folding preserves my stack for better spots.
