Hold'em table

A2o on the button is a standard steal attempt three-handed; a small raise pressures the blinds and I can fold if they play back. Calling is too weak with such a dominated kicker.

Pocket nines are a strong hand three-handed; 3-betting the button's raise builds the pot and could take it down or isolate against the big blind.

T7o is too weak to continue against a button open and a small-blind three-bet, especially out of position. Folding avoids putting 800 more chips in with a dominated offsuit hand.

A2o has poor equity and terrible playability against a 3-bet; calling 650 to win 1250 requires roughly 34% equity that this hand rarely realizes. Folding is clearly the best play.

4-5 offsuit is weak from the button facing a raise-sized pot; folding preserves chips for better spots.

J6 offsuit is too weak to continue out of position for another half-blind after the button folds. Folding avoids a dominated, poorly playable hand.

A7o is a standard button open in three-handed play, and a small raise takes the initiative while keeping the pot manageable.

53s is far too weak to defend from the small blind out of position against a button raise; folding avoids tough postflop spots with a dominated, low-equity hand.

K3 offsuit facing a raise is weak; folding avoids investing more chips with a low-equity hand.

42o is the worst starting hand; folding from the button against two blinds is clearly best with no fold equity worth pursuing.

With the button folded it's heads-up against BB; 5d7d suited plays well and a small raise applies pressure while building the pot in position-neutral heads-up spot.

64 offsuit is too weak to continue against a preflop raise; folding avoids putting more chips in with a dominated hand.

KJ offsuit is a decent button hand; raising to 250 to isolate blinds and take advantage of position.

3-4 offsuit is too weak to continue against a button raise to 2.5bb, especially out of position. Folding preserves chips for better spots.

I need only 150 to call into a 400 pot against a wide button opening range, and 87o has adequate equity and connectivity to defend my big blind, though I'll need to play carefully post-flop out of position.

The flop paired nines, giving me a weak pair with 8-7 and no draw worth betting. Out of position against the preflop raiser, checking keeps the pot small and lets me evaluate their continuation bet before deciding.

Opponent checked flop on a paired dry board; a continuation bet with overcards and backdoor equity can take the pot or build value if called.

AJs is a strong button hand in a three-handed game, so I open to 3bb to build the pot and take the initiative rather than flat the big blind.

Ace-six offsuit is too weak to defend against a 3x button raise out of position; folding avoids playing a dominated ace with poor equity.
