Hold'em table

75o is too weak to open from the button even three-handed; folding avoids a dominated, low-playability hand out of position postflop.

Ace-king suited is a premium hand and I'm in position against the big blind after the fold, so I raise to build the pot and take the initiative rather than just calling.

73o is well outside any reasonable BB defending range against a 3bb raise from the small blind.

T8s is a strong button open in a 3-handed game with deep stacks; raising builds the pot with position and a hand that plays well postflop.

A3 offsuit plays poorly out of position facing a 3x button open, making an easy fold preflop.

4-6 offsuit is too weak to continue against a button open; folding is the clear choice.

J7o is too weak to open profitably from the button even in 3-handed play.

Button folded, so this is heads-up versus the big blind. 78o has enough equity to complete for 50 into a 150 pot rather than fold.

Trash hand 35o heads-up but I'm in the big blind with a free check; folding gives up equity for nothing, and I can fold later if seat_1 bets.

I have middle pair on a two-heart flop and am heads-up against the big blind. A half-pot bet gets value from worse pairs and overcards while charging draws.

With 3-high unpaired trash against a flop stab into a checked-through pot, calling 100 risks too much for negligible equity.

79 offsuit is too weak to open or limp from the button in a three-handed pot, so I fold and wait for a better hand.

KQs is a premium hand in 3-handed play and I have position on both blinds, so I open-raise for value and initiative. A standard 3x raise builds the pot while keeping the range wide enough to continue profitably postflop.

Small pocket pairs like 33 play poorly out of position facing a 3bb button open with the big blind still left to act.

Q6 offsuit is too weak to defend the big blind against a button open to 3bb; folding avoids a dominated, low-playability spot.

K8s is a strong suited King that plays well in position, making a standard 2.5bb opening raise profitable on the button.

57o is too weak to continue out of position against a button open; folding avoids putting more chips in with a dominated hand.

J6 offsuit is far too weak to defend the big blind against a button raise; calling 150 more with a dominated, unplayable hand has negative EV, so folding is best.
