Hold'em table

67o is too weak to open from the button for 100 chips; folding preserves my stack for better spots.

A7o is ahead of a random big blind range in a blind-versus-blind spot, making a standard 3bb open raise profitable.

J4o is too weak to open on the button even in a 3-handed game.

J4s is a weak hand facing a raise from the big blind after the button folded; folding and preserving chips is the best play.

8s6d offsuit from the button is a weak hand with three players; folding preserves chips for better spots.

95o is too weak to complete from the small blind out of position against the big blind. Folding avoids a dominated, poorly connected hand.

KQs is a premium suited hand on the button, so I open to 3x rather than limp. This builds the pot and applies pressure before the flop.

K2o is far too weak to defend out of position against a 3bb button open.

Queen-five offsuit is too weak to defend against a 3x button raise while out of position; folding preserves my full stack for better spots.

Pocket threes is a standard opening hand on the button 3-handed; raising to 2.5bb applies pressure and builds the pot with position.

T6o is dominated and out of position against a 2.5x raise; folding is the highest-EV line.

Queen-ten offsuit is strong enough to continue against a button open, and calling 150 into this pot is better than folding or bloating the pot out of position with a dominated hand.

Top pair on a dry-ish flop; a small bet gets value from worse pairs and draws while keeping the pot controlled against the button's preflop raise.

Folding pocket threes on a Q-9-2 two-tone board facing a donk bet, as we have negligible equity and few outs.

73o is too weak to continue out of position against the big blind after the button folds. Folding avoids paying to realize little equity.
