Hold'em table

K2s is marginal but with button position and only 1bb to call, I can see a cheap flop and use position postflop.

A2 offsuit is ahead of a typical button limping range and benefits from denying the big blind a free realization of equity. A small isolation raise applies pressure while keeping the pot manageable out of position.

3d-Qs is a weak hand (Queen-high with a low kicker). Facing a raise to 400 from the small blind in position, folding preserves chips in a situation where my hand is not strong enough to continue profitably.

K2s is too weak to continue against a small blind raise after limping; folding avoids playing a dominated hand out of position.

Q3 offsuit is a weak button opening hand in this short-handed setup; folding avoids playing a dominated range.

2-10 offsuit is a weak hand from the small blind, and calling another 50 chips to see a flop against a big blind player (who may have a strong range) is not profitable. Folding preserves chips for stronger opportunities.

Holding Ac-Kh (one of the strongest starting hands), I raise to 650 to build the pot, gain initiative, and narrow the field. This is a standard strong value raise from the button against open stacks.

J4o is too weak to continue against a button raise, even with a small blind discount. Folding avoids playing a dominated, disconnected hand out of position.

QTo is dominated too often against a large button open, and calling out of position does not meet the required equity after the sizing.

K8o on the button in a 3-handed game is a reasonable open; raising to 300 applies pressure, takes initiative, and keeps position with a hand that flops decently.

AQ suited is a strong three-handed holding and plays well as a value 3-bet from the small blind against a button open. The raise pressures broad opening ranges while building value.

J3o is a weak hand in a 3-way pot. Seat 2 has raised to 1100, seat 1 raised to 300, and I'm facing 1000 to call out of position with poor equity. Folding is the optimal play here.

K8o is too weak to continue against a small blind 3-bet, even with position. Folding avoids playing a dominated hand out of flow.

QJ suited-equivalent offsuit is a strong button opening hand three-handed. I raise to apply pressure and play in position.

K5o is a weak hand that doesn't warrant committing more chips against a raise from the button. Folding preserves my stack for better opportunities.

Button likely has a wide stealing range in 3-handed play, and T3s has enough equity to defend the big blind getting 400:150 pot odds. I'll call and evaluate the flop out of position.

The flop is K-high and my T-high has no showdown value, so I check and plan to fold to a bet.

A small continuation bet leverages the preflop range advantage on this king-high board and can fold out many missed hands while preserving our gutter equity.

My Td3d has no pair or draw on this K-high flop, and calling 180 into 730 offers poor equity against the button's value range. Folding avoids further losses.

King-four offsuit is a weak hand in early position. With 100 chips to call and no evidence of weakness from the big blind, folding preserves chips for stronger starting hands.

Button folded and 99 is a strong heads-up hand against the big blind. Raising to 300 builds the pot and applies pressure while keeping weaker hands in.

Defend the big blind with a suited connected hand against the small blind's modest open; it has good postflop playability.

C-bet half pot on an A-high board to fold out overcards and weaker pairs, taking down the pot often enough to be profitable.

6-high has no made hand or meaningful draw on this ace-high board, and folding avoids continuing against the preflop raiser's continuation bet.
