Hold'em table

A9s is a strong suited ace on the button in 3-handed play; raising for value and position with a standard 2.5x open.

J6 offsuit is too weak to continue out of position against a button open, so folding is the highest-EV option.

3-4 offsuit facing a raise with a fold already in front is not worth defending; fold to preserve chips.

A6s is playable from the button in a three-handed game, so I open to 2.5bb to take the initiative rather than flat the big blind.

7c4c offsuit is weak, facing a raise out of position; not worth calling.

A7o in the big blind vs a 2.5x button open is a standard defend: I only need ~21% equity getting 150-to-700, and the ace-high dominates his likely wide range enough to see a flop. 3-betting is too thin with a dominated kicker.

Ace-high with a weak gutshot on a coordinated flop against the preflop raiser; checking keeps the pot small and avoids bloating without a made hand.

I have middle pair with an ace kicker as the preflop raiser, and the big blind checked. A small continuation bet pressures weak hands and draws while keeping the pot manageable.

Cheap call with ace-high and decent pot odds; I can fold the turn if seat_2 keeps firing without improving, and raising here risks bloating a marginal spot.

I only have ace-high on a paired board, so checking back is best; I avoid putting in chips with no showdown value and can evaluate a river bet cheaply.

I have trip sixes with the ace kicker on a paired board, so I bet for value against worse pairs, two pair, and draws while keeping the river pot manageable.

I only have ace-high on a paired board with a flush draw possible, and villain has shown aggression on every street. Calling 600 with no made hand and no fold equity is -EV, so I release the weak ace.

Weak offsuit hand (J2o) with no pair or connectivity, not worth calling from the button facing action.

4d2d is far too weak to play even from the button in a 3-handed game; folding preserves chips for better spots.

Button folded, so this is heads-up with position postflop. Q7o is too weak to just complete, but a small raise can fold out part of the big blind's range and take the pot.

32o is a weak hand facing a raise; folding is standard here.

A5s is a solid button open in a three-handed pot, so I raise to 2.5bb rather than limp or fold.

QQ is a premium hand; 3-betting for value against a single raiser builds the pot and narrows the field.

A2o is far too weak to call an 8bb 3-bet out of position against what looks like a strong range; folding preserves chips for better spots.

A5s has suited-ace playability and position against the small blind's 3-bet, and the price is acceptable, so calling is better than folding or turning it into a 4-bet bluff.

I hold an overpair (QQ) on a low, disconnected 7-3-2 board; a solid continuation bet extracts value and denies equity to any drawing hands.

Ace-high with no pair or draw on a dry board does not have enough equity to call a two-thirds-pot continuation bet from the preflop three-bettor.

3c6c offsuit is weak and not worth calling from the button with no reads yet.
