Hold'em table

Queen-six offsuit on the button in a 3-handed game is a standard open; I'll raise for position and fold equity.

Q3 offsuit is weak from the small blind facing a button raise with a BB yet to act; folding avoids investing more with a poor hand.

68o is too weak to defend the big blind against a button raise to 2.5bb; folding avoids playing a dominated, low offsuit hand out of position.

A4 suited from the button is a solid raising hand; a standard raise applies pressure to both blinds.

A4o is too weak to continue out of position against a button open; it is often dominated and plays poorly multiway.

Q2s is far too weak to defend my blind against a button raise out of position; I'm often dominated by better queens and the hand has poor postflop playability.

Nine-three offsuit is too weak to open from the button for a full big blind, so folding is the highest-EV line.

43s is far too weak to play even from the button against two blinds; folding preserves chips for better spots.

Getting 3:1 pot odds heads-up against BB with a live but weak hand; cheap to see a flop.

Heads-up versus a completed small blind, J9o is good enough to raise for initiative and fold equity rather than give a free flop.

J7 offsuit is too weak to continue against a raise; folding preserves chips.

Cheap price to see a flop from the button with a speculative hand in a 3-handed pot.

42s is too weak to complete out of position with the big blind still to act; folding avoids investing more with a dominated hand.

Button limped, indicating a weak range, and QTo has solid equity heads-up; a small isolation raise can win the pot immediately or build it while I'm ahead.

6-8 offsuit facing a raise with only two players left is weak and not worth calling out of position.

65o is too weak to open or limp from the button in a three-handed pot; folding avoids a dominated, low-equity spot.

9h4s is a very weak hand even suited; folding from the small blind heads-up avoids losing more chips with a dominated holding.
