Hold'em table

6s Kh is a weak offsuit hand on the button with two players already invested; folding avoids a marginal spot against the blinds.

Button folded, leaving a blind-vs-blind spot where K-high is strong enough to raise. Raising to 300 applies pressure and takes initiative rather than completing and playing passively.

Q7o is a weak hand out of position facing a raise. The pot odds are not compelling enough to continue, and I can find better spots.

With 2c6h offsuit from the button in a 3-handed pot, calling 100 to see a flop is not profitable enough, so I fold preflop.

I'm getting 3-to-1 pot odds heads-up against the big blind, so calling with 7-4 offsuit is profitable even though it's a weak hand. Raising would risk too much with this hand.

Jc2d is a weak hand with no playability, and I'm out of position facing a limp. Folding preserves my stack for better spots.

I hold Jd6d, a weak hand that is unlikely to win against the big blind's range. Since the big blind has not raised and the pot odds are poor, folding is the most prudent play to preserve my stack.

Strong suited Ace with position; raising to 3x BB isolates the blinds and builds the pot with a playable hand.

AKs is a premium hand; 3-betting to 1200 isolates the button raiser and builds value while keeping worse hands in.

Q4s is too weak to continue against a button open and a small blind three-bet to 12bb, especially out of position. Folding saves the extra 11bb for a better spot.

I have a strong suited Broadway hand on the button and the small blind has shown aggression. A min-raise to 2100 keeps the pot controlled while denying equity and preserving fold equity.

K9o is a reasonable button open in a 3-handed game, and raising applies pressure on the blinds while taking initiative with position.

23o is too weak to continue out of position against a raise, so I fold and preserve chips.

4c 7h is a weak offsuit hand and I'm out of position facing a 300 raise; folding preserves chips for better spots.

T3o is a weak offsuit hand with poor playability, and calling another 100 preflop is not worthwhile. I'll save chips and wait for a better spot.

Seat 3 folded, seat 2 completed the big blind. With 5s 8s in the small blind facing a call of 50 more, the pot odds and hand strength don't justify continuing against one opponent.
