Hold'em table

Button open with suited connectors; a small raise builds the pot and takes initiative before the blinds.

J3 suited in the small blind facing a 2.5x button open with the big blind still to act is a clear fold; it plays poorly out of position and lacks the equity to call or 3-bet profitably.

Defend the big blind against a small button raise with suited Q6, which has adequate equity and playability heads-up.

With only queen-high on a monotone coordinated board, checking preserves equity and avoids bloating the pot against the preflop raiser.

I have top pair on a monotone flop and the big blind checked, so a small bet gets value from worse pairs and denies a free card.

Q-high without a heart has very little equity on this monotone flop and no meaningful draw. Folding avoids continuing against the button's bet.

On the button in a 3-handed game, 7s4s suited is a marginal but playable open against two blinds; a small raise takes initiative with position and decent playability.

Q2 suited is too weak to continue from the small blind against a button open with the big blind still behind.

67 offsuit is too weak to call a button open out of position, so I fold and save the 150.

7-8 suited has solid playability on the button in a three-handed pot. A small isolation raise leverages position while keeping the pot manageable.

Q6 offsuit is too weak to continue from the small blind against a button open; folding avoids putting more chips in with a dominated, unconnected hand.

3-5 offsuit is a weak hand facing a 2.5x button open out of position; folding is the standard play despite decent pot odds.

T3o is too weak to open from the button for a full big blind; folding avoids a dominated, poorly connected hand.

Button folded, heads-up SB vs BB with 100bb; 86o is a reasonable raise-or-fold steal candidate blind vs blind with some playability, so I raise to 3bb to take the pot or play in position-disadvantaged but with initiative.

8-4 offsuit is too weak to defend against a small-blind raise heads-up, especially out of position.

75 offsuit on the button in a 3-handed game is a marginal hand; it's below a standard button opening range and folding avoids playing a weak hand out of position against two blinds who can defend.

With 88 heads-up from the small blind, I raise for value and to deny the big blind a cheap flop.

95o is too weak to continue against a 4bb open; pot odds do not compensate for poor equity and reverse implied odds.

5-3 offsuit is a very weak button holding and does not justify entering against two blinds at this stack depth.

J4 offsuit is too weak to complete or raise out of position against the big blind, so folding the extra half-blind is the higher-EV line.
