Hold'em table

Q8o is on the borderline of a 3-handed button opening range, so folding is a safe, zero-EV baseline play.

Button folded, so this is heads-up versus the big blind. A3o is strong enough to raise rather than limp out of position, and a 3bb open pressures weak big-blind holdings.

62 offsuit is one of the worst hands; facing a 3bb raise out of position, folding is clearly correct.

T3o is too weak and disconnected to open from the button, even three-handed. Folding avoids putting chips in with a hand that plays poorly postflop.

AQs is a premium heads-up hand with ~65% equity against a random holding; I raise for value to build the pot while seat_2 has already folded.

75 offsuit is too weak to defend against a 3bb open from the small blind.

A3s is a decent 3-max hand; button raise builds a pot and applies pressure on blinds.

Folding Q9 offsuit from the small blind facing a 3x button open out of position.

97o is too weak to continue out of position against a button open. Folding avoids a dominated, low-equity spot.

K2o is too weak to open profitably even from the button in 3-handed play.

Button folded and pocket eights are ahead of the big blind's range, so I raise to 3bb for value and initiative rather than just complete.

The button folded and the small blind's 3x raise is likely a wide steal, so I defend my big blind with an ace in position. Calling 200 into a 600 pot is cheap, and I keep the pot small with a weak-kicker hand rather than 3-betting.

Pocket eights are an underpair on a queen-jack flop, so I check to control the pot and realize showdown value rather than bet into a range that often has me beat.

I only have ace-high with no real draw on Q-J-3, and the preflop raiser checked to me. Checking behind in position keeps the pot small, preserves my showdown value, and lets me fold cheaply if they show strength on later streets.

I have jacks and eights on a paired board, which has some showdown value but loses to most continuing hands. Checking controls the pot and avoids getting called mainly by better.

Both players checked the flop and turn, indicating weakness; my ace high has no showdown value, so a half-pot bluff has good fold equity against checked-through hands.

Pocket eights are two pair on the paired board and beat unpaired queens, overpairs, and bluffs. Calling keeps those worse hands in; raising mostly folds them out and gets action from trips.

Pocket eights is two pair with the board jacks and has showdown value against unpaired hands, but it loses to queens, jacks, and higher pairs. With no bet facing me, checking is best since a bet mostly gets called by better.

T9s is a strong suited connector on the button in a 3-handed game, so I open-raise to 3bb to build the pot in position and apply pressure.

52s is far too weak to call a 3x button raise, especially with the big blind still to act behind me. Folding preserves chips for better spots.

Getting 2.25 to 1 direct pot odds closing the action against a button open in 3-handed play, K9o has sufficient equity to defend the big blind.

Check to the preflop raiser out of position with King-high.

As the preflop raiser I c-bet small on a paired flop after the big blind checks. Two overcards and a gutshot give enough equity to semi-bluff and apply pressure.

I have King-high with no made pair or direct draw on a paired board out of position, making an easy fold against the continuation bet.

JTs is a strong suited connector and I have the button in a 3-handed game, so raising for initiative and position is profitable; 300 applies light pressure while keeping the pot manageable.

Q2o is a very weak hand out of position facing a button raise, making it an easy fold.

K2o is too weak to continue out of position against a button open; folding avoids a dominated spot.
