Hold'em table

A3o is a playable button open in three-handed poker; a 2.5bb raise takes the initiative in position rather than limping or folding a hand with an ace.

Facing a button open in 3-handed play, A9o has solid equity and plays better as a 3-bet to isolate or take down the pot rather than calling out of position.

6c5s is a weak hand facing a raise and a 3-bet; calling 750 more with no position and little equity is clearly -EV, so I fold preflop.

A3o is too weak to continue against a small-blind three-bet; calling or four-betting would put more chips in with a dominated, poorly playable hand.

T3o is too weak to open even from the button in 3-handed play.

Button folded, so it's heads-up against the big blind; A7s is a strong heads-up hand and raising builds the pot with fold equity while I'm out of position.

84s has enough equity and playability in position against a wide small-blind open, and the price to continue is reasonable.

I raised preflop with ace-high; on a dry low flop I likely still have the best hand, so I bet to build the pot and set the price.

I have only a gutshot with 4s8s on 6s9h5d and no pair or flush draw. Calling 400 into 1000 needs about 29% equity, which this draw does not have, so folding is best.

Pocket queens on the button is a premium hand; I raise for value to build the pot and isolate the blinds while keeping position for later streets.

42s is too weak to continue out of position against a button open; folding avoids paying 250 with a hand that flops poorly and has little equity.

84o is too weak to defend against a 3x button open out of position.

Nine-five offsuit is too weak to call or open from the button, even three-handed, so folding preserves chips.

T6 offsuit is too weak to complete or raise from the small blind.

96 offsuit is too weak to open from the button, even in 3-handed play.

Completing from the SB costs only 50 into a 150 pot, needing ~25% equity; 63s has enough against a wide heads-up BB defending range to justify seeing a flop rather than surrendering the blind.

75o is too weak to raise, and checking is free after the small blind just completed.

I hold 6-high with no pair, no draw, on a very coordinated J-T-Q two-club board, so betting has little fold equity and no equity when called. Checking and folding to aggression is the cheapest line.

7-5 offsuit has no pair, no draw, and no equity on this connected flop, so checking behind is the only sensible line.

I have 75 offsuit with no pair or draw on a paired, connected board, so there is no value in betting. Checking is free and keeps the pot small.

I only have the board pair of jacks and lose to most live hands, but seat_3 has timed out on the last two streets. A minimum bet risks the least if they wake up, and a timeout fallback must fold, so it is better than checking for a small chop.

My 6-3 doesn't connect at all, so my best hand is just the board's pair of jacks (J-J-Q-T-9) - the minimum possible holding. Any card seat_1 plays beats me, and the best I can do calling is chop with 8-high air, so calling has zero upside and folding loses the least.

Pocket sixes on the button in 3-handed play is a profitable open-raise; I take position and apply pressure on the blinds.

92o is too weak to continue out of position against a button raise, especially with the big blind still to act. Folding preserves the stack for better spots.

J5o is far too weak to defend the big blind against a 3x open.
