Hold'em table

Nine-four offsuit is one of the weakest hands even three-handed; with no fold equity incentive and two players left to act, folding the button preserves my 100bb stack for a better spot.

79o is too weak to complete out of position against the big blind after the button folds, so I give up the small blind.

87 offsuit is too weak to open from the button for value, and limping is unattractive, so I fold and preserve my stack.

J6o is too weak to complete or raise from the small blind out of position.

On the button in 3-handed play, J9o is a standard open-raising hand to steal the blinds and take position postflop.

72 offsuit is the worst hand in the deck and I am out of position against a button raise. Folding preserves chips; calling 150 more has no profitable upside.

Ace-three offsuit is weak and easily dominated, but I only need to call 100 into a 350 pot after the small blind folded. That price is good enough to continue out of the big blind rather than fold.

Ace-high with no pair or draw on a coordinated QKT flop has little value, so I check rather than bluff into the preflop raiser. Checking is free and keeps the pot small.

Flopped a king-high straight on a monotone three-flush board without a diamond redraw; checking behind controls the pot and realizes equity safely.

Ace-high has no pair or draw on this coordinated turn, so I take the free card rather than bluff into a range that connects with QKT and the diamond flush.

I have a King-high straight on a board with three diamonds. After opponent checks twice, I bet for value against pairs and lower holdings while charging single-diamond hands.

Ace-high with no pair or draw on a coordinated three-diamond board is too weak to continue against a turn bet. Folding avoids putting more chips in with almost no equity.

K7s from the button is a standard open; raising builds the pot with position and folds out weaker hands. A min-plus raise to 300 applies light pressure while keeping the stack manageable.

56 offsuit is too weak to call a button raise from the small blind out of position. Folding avoids putting more chips in with a dominated, low-equity hand.

J4o is too weak to defend against a 3bb open from the button out of position.

Nine-deuce offsuit is too weak to call or raise from the button, even three-handed. Folding avoids putting a big blind into a hand with almost no equity or playability.

Q7o is too weak to comfortably complete or raise out of position against the big blind, making an easy fold.

A7o is well within standard opening range from the button in 3-handed play, making a 2.5bb raise standard.

T9s is far too weak to defend against a 2.5x raise from the button, especially out of position from the small blind. Folding preserves chips for better spots.

65 offsuit is too weak to defend out of position against a button open, even with a favorable price. Folding avoids a dominated, low-playability spot.
