Hold'em table

With Ace-high on the button in a 3-handed game, raising to 300 applies pressure and can take down the blinds or isolate weaker hands.

A3o is too weak to continue out of position against a button open with the big blind still to act. Folding avoids a dominated, low-equity spot.

T2o is a very weak hand with poor playability out of position against a preflop raiser; folding avoids further loss despite the pot odds.

52s is too weak to open from the button for a full big blind, so folding preserves chips.

A8o is a favorite against a random hand and we have fold equity. Raising to 3bb puts pressure on the big blind and builds a pot with a decent hand, while avoiding playing out of position with a marginal hand in a limped pot.

Ace-eight offsuit is strong enough to 3-bet against a small blind open, and raising to 800 applies pressure while keeping the pot manageable if called.

A8o is a weak hand to call a 3-bet out of position, and raising again would be an unnecessary bluff.

A5o is a marginal hand but in 3-handed play, raising from the button (first to act preflop) puts pressure on the blinds and can win the pot immediately. I raise to 2.5x to steal, folding to a re-raise.

K7o is a weak offsuit hand out of position against a button raise, and calling 200 more with poor playability is not profitable. Folding avoids further losses.

J5o is too weak to continue out of position against a button open; folding avoids a dominated, poorly connected hand.

K2o is too weak to call or raise from the button in a three-handed pot, so folding avoids playing a dominated hand out of position postflop.

K6 offsuit is too weak to continue out of position against the big blind after the button folds.

T5o is too weak and disconnected to open from the button, and limping would be worse. Folding preserves chips for better hands.

With the button folding, we are heads-up against the big blind. A2o is a marginal hand, but raising to 2.5x the big blind can steal the pot or build a pot with an ace if called. Folding loses the small blind, and calling out of position is weak.

Holding pocket aces in the big blind, I reraise for value and to build the pot against the small blind's open.

A2o is a weak hand that performs poorly against a 3-bet from the big blind, especially out of position. Folding preserves chips for a better opportunity.

AQs is a strong hand on the button; raising to 3x the big blind builds the pot and puts pressure on the blinds.

9d6h is a weak offsuit hand out of position against a button raise, and calling 250 into 450 with the big blind still to act is not profitable enough.

Q3 offsuit is too weak to defend the big blind against a 3x button open after the small blind folds.
