Hold'em table

Blind vs blind after the button folds, J8o is strong enough to open-raise for value and steal equity from out of position.

85 offsuit is too weak to continue against a raise, even heads-up from the big blind.

7h 3s is a weak, unsuited, disconnected hand that is an easy fold from the button.

Button folded, so this is heads-up versus the big blind. 68o has enough equity against a random hand to call 50 into a 150 pot.

A4o has solid equity heads-up against a small blind limper's weak range; a standard 3x raise builds the pot and takes initiative while folding out junk.

68o is too weak to continue against a 3x raise from the big blind; folding avoids putting more chips in with a dominated, unsuited hand.

A8o is a standard button open in three-handed play. A 2.5bb raise builds the pot with position and folds out weaker hands.

42s is far too weak to call a 2.5x button raise, especially with the big blind still to act behind me who could squeeze. Folding loses almost nothing versus the tiny equity this hand has.

J4o is too weak to defend out of position against a button raise.

Button with suited J9 in position against two blinds; a 3x raise takes initiative and pressure post-flop.

43 offsuit is far too weak to defend out of position against a button raise.

Heads-up versus a button open, A7o has enough equity and an ace to continue. Calling 200 into 450 is better than folding or turning a dominated ace into a bloated 3-bet.

Ace-high with no draw on 983 has little value to bet into the preflop raiser, and checking is free with position still to act.

I have top pair (jacks kicker) heads-up after the BB checked the flop. Betting ~60% pot charges straight draws (T7, 76) and worse nines while building the pot with a strong hand.

Ace-high with no pair and no draw on 9-8-3 is too weak to call a flop bet. Folding avoids putting more chips in with almost no equity.

J9o is playable from the button 3-handed; raising to 200 applies pressure and leverages position.

9-7 suited is too weak to continue out of position against a button open, and a 3-bet bluff is poorly placed. Folding avoids paying 1.5bb more with a dominated, low-equity hand.

AKs is a premium hand; I should 3-bet for value against the button's open rather than just call, building a bigger pot while I likely have the best hand.

J9o is too weak to defend against a preflop 3-bet from the big blind.

J2 suited is too weak and easily dominated to open from the button, so I fold rather than invest chips with poor reverse implied odds.

Heads-up after the button folds, a min-raise from the SB has strong fold equity; 32o is too weak to limp and play out of position, so I apply pressure cheaply and can release if the BB continues aggressively.

Q2o is too weak to defend even against a min-raise from the small blind.
