Hold'em table

AQo on the button is a premium hand; I open-raise for value and fold equity rather than just calling. A 3x open to 300 builds the pot while keeping the option to fold to heavy resistance.

A4o is too weak to continue out of position against a button open, and calling or raising would often leave me dominated or playing a poor hand OOP.

J3 offsuit is weak facing a raise; folding from the big blind is correct here.

86o is too weak to open from the button in a three-handed pot; folding avoids playing a low offsuit hand out of position postflop against two opponents.

Heads-up after button fold; Q9o is playable, raise to isolate and take initiative.

72o is the worst hand in poker and I'm facing a raise out of position; calling 150 more with 7-high has no profitable line postflop. Easy fold despite the small price.

AK offsuit on the button is a premium hand; raise to build the pot and take initiative.

62 offsuit is nearly the worst starting hand, and facing a 3x button raise out of position leaves no profitable way to play it. Folding preserves 250 chips that calling would waste with minimal equity.

ATs is ahead of a typical button open and plays better as a 3-bet out of position than as a flat. A raise to 900 is a standard size that denies equity and builds the pot.

AK is strong enough to 4-bet against a re-raise, applying pressure and building a pot with a premium hand.

ATs is too weak to continue out of position against a button 4-bet to 24bb; calling realizes poorly and a jam is not profitable enough.

T2 offsuit is one of the weakest hands in hold'em with no suit connectivity or pair potential; even on the button 3-handed, paying 100 to continue has negative expectation, so folding is standard.

Pocket queens is a premium hand heads-up versus the big blind after the button folded, so I raise to 3bb for value rather than just completing.

Q3o is weak facing a 3bb raise; folding is the standard play here.

KQo is a clear button open in 3-handed play; a 2.5bb raise builds the pot with a strong hand and applies pressure on the blinds.

3c5d offsuit is weak, facing a raise with a call price against two other players; not worth continuing.

Jack-six offsuit is far too weak to defend the big blind against a 2.5bb button raise heads-up; it flops poorly and plays badly out of position.

A4 offsuit on the button is a reasonable raising hand; raising to 250 builds the pot and takes advantage of position against two limpers/blinds.

9-5 offsuit is far too weak to call a 2.5bb raise out of position from the small blind; folding preserves chips for better spots.

ATo has enough equity and playability versus a button open to continue. Calling 150 into a 400 pot is the standard, lower-variance line rather than a light 3-bet.

Ace-high with no pair or draw on a paired flop, out of position against the preflop raiser. Checking keeps the pot small and avoids building a pot I am unlikely to win if called or raised.

Board is dry and paired; a continuation bet here can pick up the pot since my opponent likely missed as well, and I have overcard equity with Ace high.

Ace-high with no pair and no draw on a paired 9-8-8 board is too weak to continue against a half-pot c-bet from the preflop raiser. Folding avoids putting more chips in with almost no equity.
