Hold'em table

K3s is a playable suited hand from the button, and raising to 2.5bb applies pressure on the blinds while keeping initiative with position.

J5o from the small blind facing a button open, with the big blind still left to act, is a clear fold. Calling out of position with a weak offsuit hand loses money.

J6 suited is too weak to defend against a button open in this short-handed configuration, especially out of position.

J2 offsuit is too weak to open from the button in 3-handed play with 100bb stacks, and limping is weak, so folding is the clean play.

With 4-3 suited in the small blind facing the big blind, folding avoids realizing poor equity out of position in a shallow blind-only pot.

On the button, 76 offsuit is a reasonable steal candidate against the blinds. A small open to 2.5bb applies pressure while keeping the risk controlled.

99 is strong enough to 3-bet for value against a wide button open; raising to 800 isolates and pressures the big blind.

Q7o is far too weak to continue against a button open and a small-blind 3-bet, with the opener still left to act behind. Folding the big blind is clearly best.

Suitedness is absent and 76 offsuit performs poorly against a substantial three-bet, especially out of position postflop. Folding preserves chips.

KJo is strong enough to open from the button; raising to 300 puts pressure on the blinds and takes initiative.

ATo from the small blind against a 3-handed button open is ahead of the button's wide range. A 3-bet to 12bb takes the initiative and avoids playing out of position with a big blind still left to act.

Q5 offsuit is too weak to continue from the big blind facing an open and a large 3-bet.

T2o is too weak to open profitably from the button in 3-handed play with 100bb stacks against two blinds. Folding is the standard play.

T4 offsuit is too weak to defend the small blind against the big blind at this stack depth.

K2 offsuit is a weak button holding with poor playability and domination risk; folding avoids marginal multiway exposure.

A6o is ahead of the big blind's random range heads-up, and a small raise can take the pot preflop while keeping the risk modest.

Blind vs blind, the small blind min-raised and I'm getting 4:1 to call (100 into 400). K6o is well ahead of a wide SB range, so calling in position is clearly profitable.

I have top pair with a weak kicker on a wet board, so I should bet for protection and value against draws and worse aces. A moderate bet around 300 into the 400 pot applies pressure while keeping the pot manageable.

Getting 2.3:1 with a gutshot to the wheel-side straight (any 4), a backdoor flush draw and a king overcard. That is enough equity plus implied odds to defend against a 75% c-bet heads-up.

I have a nut-ish diamond flush draw with a king overcard, and the opponent checked the turn by timeout fallback. A 60% pot semi-bluff can win the pot now and still has equity if called.

I have top pair with a decent kicker and am getting good pot odds to continue. Calling is reasonable to see the river and keep the pot manageable against a possible stronger ace or two-pair hand.

The river brings a third diamond and possible straights, so my top pair is often behind if I bet. Checking lets me see the river action and potentially catch bluffs without value-owning myself.

King-high has almost no showdown value, and the river diamond completes a flush that fits my line, so I'm betting about 64% of the pot to fold out weaker Ax and missed draws.
