Hold'em table

K7o is a standard open from the button in 3-handed play, so I'm raising to 2.5bb to pressure both blinds.

J2o is a weak, dominated hand out of position against a button raise; folding avoids marginal spots.

9h3c is a weak offsuit hand with poor playability from the button against a raise; folding avoids investing 100 chips with a dominated, low-equity holding.

2s6s is a weak hand in a 3-handed game. With only 50 chips already invested, folding to the big blind's raise is the correct play, especially when facing a 50-chip call with significant positional disadvantage and poor hand equity.

8-2 offsuit is one of the weakest hands in poker. Folding preflop from the button against two opponents is the mathematically sound play, preserving chips for stronger holdings.

A9 suited is a strong hand blind-vs-blind after the button folds, so I'm raising to 3bb for value and initiative.

Calling 200 more with J9o in position against a small blind raise; pot odds are good and the hand has decent equity.

I raised from the small blind and hold top pair with a 9 kicker on a dry ace-high board, so a small one-third-pot c-bet gets value from worse aces, queens and draws. It also protects my hand while keeping the pot manageable.

I have J9 offsuit on an A-Q-6 flop with no pair, no draw, and only a weak backdoor straight possibility. Facing a bet from the preflop raiser, folding is best since calling or bluff-raising would risk chips with minimal equity.

J3 offsuit is below a solid button opening range three-handed with 100bb stacks against two blinds, so folding is the disciplined play.

85o is a weak offsuit hand with poor playability; facing a raise from the big blind with only 50 to call but out of position, folding avoids bleeding chips with a dominated hand.

94o is a weak offsuit hand with poor playability, and calling 100 chips out of position against two players is not profitable. Folding preserves chips for better spots.

J9o is a weak hand in 3-way play. With only 50 chips already invested and facing a 100-chip big blind raise, folding minimizes losses against likely superior holdings.

J7o is a weak hand from the button in a 3-handed game. With a 100 chip call required and two opponents already in the pot, folding minimizes losses on a marginal holding with poor playability post-flop.

Blind-vs-blind with a suited connector-ish hand; raising to 3bb applies pressure and takes initiative, which is standard SB strategy against a single BB.

With 4s2c out of position against a small-blind raise, folding avoids playing a very weak hand for 200 more chips.
