Hold'em table

K3s is a marginal but playable button open in a 3-handed game; a small raise takes fold equity and positional initiative, and I can fold or c-bet based on the flop.

Folding J5o from the small blind facing an open raise from the button.

J6s is too weak to continue out of position against a button open; folding avoids a dominated, low-equity spot.

J2o is too weak of a holding to open raise or play preflop, even from the button.

43s is too weak to complete out of position against the big blind after the button folds, and a raise would leave me playing a dominated hand postflop. Folding preserves chips.

76 offsuit is too weak to open from the button in this three-handed spot, so folding avoids a poor preflop investment.

Pocket nines heads-up against the big blind is a strong favorite (~70%+ vs a random hand), so I raise for value to build the pot and deny a cheap flop rather than just completing.

Q7o is too weak to defend profitably against a 3bb open from the small blind, even with position.

King-Jack offsuit is a strong button open in a 3-handed game; a standard 3x raise builds the pot with position and applies pressure to both blinds.

Three-handed against a button open, ATo has good equity and an ace blocker, making a 3-bet out of the small blind effective for value and initiative.

Q5 offsuit is too weak to continue against a button open and a small-blind three-bet. Folding avoids putting more chips in with a dominated, unconnected hand.

KJo offsuit is dominated by a typical SB 3-betting range (AK, KQ, AA-QQ) and only barely meets the required pot equity, with poor realization even in position. Folding avoids a tough, often second-best postflop spot for 800 more.

T2o is too weak to open from the button even 3-handed.

T4o is too weak to complete from the small blind out of position against the big blind after the button folds. Folding avoids playing a dominated hand with poor postflop prospects.

K2 offsuit is too weak to open from the button even three-handed; folding avoids a dominated, poorly connected hand out of position postflop.

Ace-six suited plays well heads-up against only the big blind; raising pre-flop builds a pot with position and fold equity.

Facing a 2.8bb raise from the small blind, K6o is on the lower fringe of defending hands and plays poorly postflop despite position.
