Hold'em table

4-6 offsuit is a weak hand not worth investing chips in from the button facing a raise to call.

Button folded, so I am heads-up versus the big blind with JTo. A raise to 300 takes the initiative rather than completing the small blind.

8h2c is one of the worst hands in hold'em and I'm out of position facing a 3x raise from the small blind. Folding loses only the 100 blind already committed; calling or raising would invest more with almost no equity.

AJo is a strong button open; a 2.5bb raise builds the pot and applies pressure before the blinds act.

T5s is a weak hand out of position against a 2.5x raise; folding avoids losing more chips with a marginal suited connector.

Suited connector 5c8c on the button is a standard min-plus open; raising to 3x builds a pot with position and can win blinds immediately.

84s is too weak to continue against a button 3x open after the small blind folds, so folding is the highest-EV option.

A8o on the button in a 3-handed pot is a solid raising hand; raising to 250 builds the pot with position advantage.

QJo is playable from the small blind against a 2.5x button open, and calling 200 into a 400 pot keeps the hand in range without bloating the pot out of position.

Nine-five offsuit is far too weak to defend a 2.5bb raise out of position against two active players, even with good pot odds. Folding preserves chips for a spot with real equity.

Top pair with a queen kicker on a dry flop is strong enough to bet for value against a wide button open. A small donk builds the pot and charges weaker jacks and overcards.

Ace-high with no pair or draw facing a flop bet; not enough equity to continue.

72 offsuit is the worst starting hand and I am first to act, so folding avoids putting 100 chips in with almost no equity.

T9s plays well heads-up against a limper; a small iso-raise builds the pot with position and can win it outright preflop.

AK is a premium hand; I'll 3-bet to build the pot and isolate against the single raiser.

T9s is too weak to continue against a 3-bet out of position; folding preserves 600 chips rather than playing a dominated suited connector.

84 offsuit is a weak hand; button folded, but facing BB with weak holding heads-up isn't profitable enough to call, so I fold to save chips.
