Hold'em table

K3 offsuit is a weak hand from the button facing a raise-sized call in a 3-handed pot; not worth continuing.

Jack-two offsuit is a weak hand out of position in 3-max. With seat_1 already folded, I face a 50 chip call against the big blind, but J2o lacks the strength to profitably continue preflop from the small blind. Folding minimizes losses on marginal hands.

6-3 offsuit is a weak hand with poor equity against most ranges. From the button with antes considered, folding preserves chips and avoids difficult post-flop situations against two opponents.

AcJc is a strong heads-up blind-versus-blind holding and should be raised for value and initiative.

Heads-up with a suited-ish ace-wheel card, 3-betting isolates and builds equity against a wide SB open.

AcJc is strong enough to defend against a heads-up blind 3-bet, and calling preserves the opponent's wider range while keeping the pot manageable out of position.

Check the nut-club draw with two overcards in this 3-bet pot, retaining flexibility to respond to a continuation bet.

As preflop aggressor on a dry, uncoordinated board, a half-pot continuation bet applies pressure and picks up folds from weak calling hands, since I have only ace-high with no pair.

The small continuation bet gives reasonable pot odds with two overcards and backdoor club potential against a potentially wide 3-bet range. Calling preserves flexibility on later streets.

With only ace-high on a low, connected board after calling the flop c-bet, checking preserves equity and avoids inflating the pot against the preflop aggressor.

I only have ace-high with no pair or draw; opponent called my flop bet showing some strength, so I'll check back the turn rather than bluff into a likely made hand.

After the turn check, opponent's range is capped and should contain many one-pair hands without a spade. A sizable river bluff credibly represents a flush or trips and pressures those holdings.

My hand is only bottom pair with a weak kicker; villain's passive line turning into a big river lead after mentioning completed draws strongly suggests a flush or better, making a call unprofitable.

Button J8 suited is worth opening in this three-handed spot. A 2.5bb raise applies pressure while retaining positional advantage.

AJ offsuit on the button is a solid raising hand heads-up-ish against blinds; a standard 3x open builds the pot with a good hand and pressures both blinds.

J5o is a weak hand that doesn't benefit from multiway action, especially out of position from the small blind against a button raise. Folding preserves chips for better opportunities.

8-3 offsuit is far too weak to defend against a button 3x raise heads-up out of position.

2-5o is a weak hand in early position. With only 100 chips to call and a marginal holding, folding preserves chips for stronger opportunities while minimizing expected loss.

A8 offsuit is a strong heads-up small-blind holding and benefits from applying pressure preflop.

On the button, K2 offsuit has enough high-card value to open against the blinds at a small sizing.

9-4 offsuit is a weak hand facing a raise; folding is correct here.
