Holdem table

Weak offsuit low cards (4-6) with no suit connection facing a raise-heavy 3-way pot; not worth investing chips from the button in a marginal spot.

Button folded, so Q9o is playable heads-up against the big blind. A small raise takes the initiative and can win the pot immediately or build it with a hand that flops well.

J2 offsuit is too weak to open from the button for a full big blind; folding avoids a dominated, low-playability hand.

K6s is a reasonable suited hand to complete from the SB for only 50 more, giving position and fold equity potential on the flop against a single opponent.

I can check for free with a weak suited hand, no reason to raise.

I have second pair (K on an A-high board) with a diamond draw; checking keeps the pot small and gets a free card.

Weak hand with no pair or draw; checking behind is free and avoids building a pot I can't win.

I hold Kd giving me the nut ace-high flush on this turn, so I bet for value against seat_1's checking range; a modest 200 into 200 keeps weaker flushes and draws paying.

I have no pair, no diamond, and no meaningful equity on this board; folding to the bet is correct with air.

KTo is a solid opening hand on the button in 3-handed play, and raising builds the pot while keeping positional advantage postflop.

4s9h offsuit is weak and out of position against a button raise; folding is standard here.

J4o is too weak to call a button open out of position; the price does not justify continuing.

6-7 offsuit from the button facing a raise-limp situation isn't strong enough to continue in a 3-handed game with no equity edge; folding preserves chips for better spots.

K7o is too weak to play out of position against the big blind after the button folds, so I give up the small blind rather than call or inflate the pot.

Q6s is suited and playable from the button in three-handed, so I open to 2.5bb rather than limp or fold.

98 offsuit is too weak to defend out of position against a button raise with the big blind still to act; calling risks playing a marginal hand multiway OOP for 2.5x. Folding preserves chips for better spots.

A3 offsuit is a marginal hand but getting good pot odds heads-up against a single raise, so calling is fine.

I hold three aces (trip aces with top kicker) after flopping into a strong hand on an A-A-9 board, so I bet to build the pot while the dry board limits opponent's outs.

Queen-high with no pair and no draw on a paired-ace flop has too little equity to call a 350 bet. Folding avoids putting more chips in with a missed hand.

7h4d offsuit is a very weak hand even from the button in 3-handed play; folding preserves chips for better spots.

J6 offsuit is a weak hand heads-up against BB with only a small blind invested; folding is cheaper than calling with poor equity.
