Hold'em table

KQ offsuit is a strong button opening hand three-handed, and a 2.5 big blind raise applies pressure while keeping the pot manageable.

J3s is a weak offsuit hand facing a 2.5x raise out of position; folding is clearly best.

8-J offsuit is a weak hand that ranks poorly against a raise from the button. Folding preserves chips for stronger opportunities.

Suited connector 89h is a fine cheap call from the button with 100 to see a flop; folding is too tight and raising overcommits a marginal hand.

9-3 offsuit is one of the weakest hands in poker. Even though it only costs 50 more chips to call, the hand has poor equity against likely holdings and will be difficult to play out of position post-flop, making a fold the most profitable long-term decision.

A4 offsuit is a marginal hand to raise out of position. Checking takes the free flop without building a larger pot.

I have ace-high with no strong draw on a connected, two-club flop. Checking keeps the pot small out of position.

Middle pair on a dry board heads-up; small bet builds pot and protects against draws while keeping control.

Ace-high with no club and only weak backdoor draws is unlikely to realize enough equity out of position against this flop bet.

Pocket tens is a premium hand in 3-handed play. A 6.5x raise establishes dominance and builds the pot with a strong hand. This aggressive line maximizes value while defining my hand range as strong.

K4 suited is too weak to defend from the small blind against a 6.5-big-blind open, especially with the big blind still to act.

7c8h is a weak suited-connector hand facing a 6.5bb raise out of position heads-up; folding is clearly best.

Nine-six offsuit is too weak to open from the button against two unknown blinds at 100 big blinds.

AKs is a premium raising hand heads-up; I build the pot and apply pressure from the SB.

Q8o is a weak hand that doesn't warrant calling a 3x raise. Folding preserves chips for better opportunities.

6d3h is the worst type of hand; folding out of position with no pot odds justification is cheapest.

T9o is a weak hand in a 3-handed game. With the button folded and facing a big blind who has already called, folding saves chips against a better-positioned opponent.

4h7d is a weak hand (worst position relative to blinds, out of position as button). Folding preserves chips against an aggressive opening; the small blind has already limped and big blind can act. Not worth the investment to see a flop with this poor holding.

K8 suited is strong enough to raise heads-up from the small blind. Raising to 300 pressures the big blind while keeping the pot manageable out of position.

A8o is dominated against a 3x SB raise; folding the extra 200 is the profitable play heads-up.
