Hold'em table

74o on the button is a weak hand facing two players; folding is the profitable play.

Ace-king is a premium hand heads-up against the big blind. Raising to 3bb builds value against weaker calls and charges the opponent to play in position.

84o is a weak offsuit hand facing a 3x raise; folding is the disciplined play from the big blind.

Q8 offsuit is strong enough to open on the button three-handed. Raising pressures the blinds and gives us position if called.

9-5 suited is too weak to call a button raise out of position with the big blind still to act; folding preserves chips.

K3 offsuit out of position against a 2.5x raise is a clear fold; calling with dominated trash just loses chips.

On the button in a 3-handed game, 97o is a reasonable hand to raise with and try to take the blinds or play in position. A raise to 300 applies pressure while keeping the risk controlled.

7c3d is dominated trash facing a 3x open from the button; calling 250 more has no equity edge. Fold and wait for a better spot.

J5 offsuit is too weak to defend profitably against a 3bb button raise out of position. Its poor playability and domination risk favor folding.

6-2 offsuit is one of the worst hands in hold'em; folding from the button costs nothing and preserves chips.

J9 offsuit is strong enough to open blind versus blind after the button folds. Raising to 3 big blinds pressures the big blind and compensates for playing out of position.

6-4 offsuit is too weak to defend against a 3x small-blind raise, especially out of position; folding preserves chips.

65 offsuit is below a standard button opening range at 100bb and has limited postflop equity realization. Without evidence that the blinds overfold, folding is preferable to a marginal steal or limp.

With 3d5s out of position and only the big blind left, folding avoids investing more chips with a very weak hand.

Suited ace on the button, raising to steal blinds and take initiative with position.

T5o is far too weak to call 3x against a button raise with two players behind potential; folding is clearly best.

KJo is strong enough to defend against a button open, with only 200 to call into a 450 pot. Calling keeps weaker hands in the opponent's range and avoids inflating the pot out of position.

Middle pair has showdown value, but this ace-high board favors the preflop raiser. Checking keeps the pot controlled and allows weaker hands to bluff.

I have top pair on a draw-heavy board and position; betting for value and protection after the big blind checks.

Middle pair with a strong kicker has enough showdown value to defend against a button continuation bet of just over half the pot. Calling keeps bluffs in and avoids inflating the pot against stronger hands.

KJ has showdown value but gains little from leading into the preflop raiser on this paired, ace-high board. Checking keeps weaker hands and bluffs in the opponent's range while avoiding inflating the pot against aces or trips.

I have top pair with an ace on a paired board and position; betting for value and protection against draws or weaker jacks.

Against a second substantial barrel, my jacks are primarily a bluff-catcher with very little improvement potential against Ax or 9x. Holding a king also blocks several natural straight-draw bluffs, making this a reasonable turn fold.
