Hold'em table

A7 suited is a solid button open in three-handed play, so I raise to 2.5bb to build the pot and apply pressure.

Pocket sevens has strong equity against a button open in a 3-max game, and 3-betting from the SB isolates the opener, builds a pot, and discourages a cheap squeeze from the big blind. Calling OOP multiway with a medium pair is less profitable than applying pressure now.

A4 offsuit facing a raise and a large 3bet to 900 is not strong enough to continue; folding preserves chips.

A7s is too weak to continue against a 9bb three-bet; it is often dominated and does not have enough equity or implied odds to call.

On the button three-handed, Q7o is a marginal but workable steal hand; a min-raise attacks the blinds with position and folds out weak holdings cheaply.

KQo is strong enough to 3-bet a button open once the small blind has folded, and a raise to 650 builds the pot while still leaving room to continue.

Queen-seven offsuit is far too weak to continue against a 3-bet from the big blind; calling 450 more into a 900 pot with a dominated hand has poor equity and no implied odds. Folding preserves chips for better spots.

J5 offsuit is a weak hand from the button facing a raise-sized call; folding preserves chips for better spots.

Button folded, so I raise T7-offsuit as a blind steal; it has enough equity and straight potential if called and pressures the big blind out of position.

25s is near the bottom of the range and only gets about 30-33% equity against a small-blind 3x raise, below the ~33% needed to call 200 into a 400 pot, with poor equity realization even in position. Folding surrenders only the sunk blind.

K3o is too weak and disconnected to open from the button, even three-handed. Folding avoids playing a dominated offsuit hand out of position postflop against likely continues.

Getting 3:1 pot odds (call 50 into 150) with 43o heads-up vs the BB's wide range; my ~36% equity makes completing cheap and folding too tight, while raising risks 250 more with little fold equity.

J7 offsuit is weak; checking my option in the big blind for free is best.

I hold bottom pair (fours) on a K-J-4 board with no one showing aggression preflop; checking keeps the pot small and avoids building it out of position with a marginal hand.

I have top pair (Jacks) on a fairly dry board; betting for value and to charge draws.

I have bottom pair (4s) and only need ~27% equity to call 120 into 320; a small BB stab on K-high board includes enough draws and bluffs that my pair is often good, and folding a pair this cheaply is too tight.

I hold bottom pair (4s with the 4h on board), which has some showdown value, and checking is free with to_call 0. Raising into the flop aggressor with such a weak kicker risks bloating the pot, so I keep it small and reassess if he bets the turn.

I only have middle pair (jacks) with no additional draws on a wet board; checking keeps the pot controlled against a caller who may hold a king or flush draw.

Only a middling pair of jacks on a coordinated board with passive action all around; better to check back and take a cheap showdown.

On the button in a 3-handed game I should open wide, and J8o is a marginal but playable steal; a min-raise keeps risk low while applying pressure on both blinds.

AJ offsuit is a strong hand; 3-betting the button's open builds the pot and can win it outright.

J8o is too weak to continue against a button open and small-blind three-bet, especially out of position. Folding avoids putting more chips in with a dominated, poorly connected hand.

Jack-eight offsuit is far too weak to call a 3-bet, even getting 3:1 pot odds; when I flop a jack I'm usually dominated, and my equity rarely realizes well. Folding preserves chips for better spots.

6-8 offsuit is a weak hand out of position value-wise on the button facing a raise-limp scenario; folding is fine but with only 100 to call and being on button I could see limping - however hand is too weak, better to fold and preserve chips.

86o is too weak to complete from the small blind out of position against the big blind, and raising it as a bluff has poor postflop playability. Folding avoids putting more chips in with a hand that is usually dominated.
