Hold'em table

Q6 offsuit is too weak to open from the button; folding avoids a dominated, poorly connected hand with no investment yet.

Suited 54 in the small blind after the button folds; completing for 50 into a 150 pot is a cheap price with a hand that can make straights and flushes. I can fold easily if the big blind raises.

J7o offsuit is weak; checking the big blind option for free is best rather than raising.

I have 5-high with no draws worth betting; checking is free and I can fold to aggression on this A-K-9 board.

No made hand or draw with 7s Jh on K-9-A board; check to control pot size.

I hold 5-high with no draw on a paired board; checking is free and I can easily fold to any bet.

No pair, weak kicker, board is heavily paired with aces; no value in betting with this weak holding, so check to see the river cheaply.

I hold 5-high with no pair; the board plays itself (aces). Betting can only lose money against a checked-down opponent, so checking to a free showdown is optimal.

I have no pair and no flush draw, just jack-high, so checking is best with no value to bet and no bluff equity given the board.

K9s on the button is a standard open; a min-raise to 300 builds the pot with position while keeping the range wide. Folding is too weak, calling gives blinds a cheap flop.

Weak offsuit low cards facing a 3x raise from the button; not worth continuing from the small blind.

AKo is a premium hand versus a button open, and a 3-bet to 1000 builds the pot while denying equity to weaker hands.

K9o is far too weak to continue against a big blind 3-bet; I'm dominated by stronger kings and crushed by overpairs, and calling 700 into a 1350 pot with poor equity is unprofitable. Folding preserves chips for better spots.

Suited connector on the button with two players to act; a standard raise builds the pot and lets me use position postflop.

Q3s is too weak to continue out of position against a button open, especially with the big blind still to act. Folding avoids a dominated, low-equity spot.

K5o from the big blind is dominated too often against a button raise and plays poorly out of position postflop; the pot odds are marginal at best, so folding is the clean play.

Three-handed on the button, 93s is a standard wide open with position and suited connectivity; a small raise is better than limping or folding.

K8o is far too weak to defend the small blind against a button raise, especially out of position with the big blind still able to continue. Dominated king hands make this a clear fold.

Q7 offsuit is weak, facing a raise heads-up with only a small additional call to fold; not worth continuing out of position.

K4s is a marginal suited hand, but on the button 3-handed I have position and only need 100 to see a flop. Calling keeps the pot small and lets me play postflop with the best position.

Cheap to complete the small blind with a weak king-high hand in a limped multiway pot; not strong enough to raise.

J7 offsuit is too weak to raise from the big blind against two limpers, and checking is free.

King high with backdoor draw only; no reason to bet into two players with a weak holding, check and see next card cheaply.

Two pair on an ace-high flop is strong enough to bet for value against ace-x and draws. A two-thirds pot bet builds the pot while keeping weaker hands in.

I hold a king-high flush draw with position on both opponents; calling 200 into a 500 pot needs only ~22% equity and my draw has ~35%, so folding is too tight and raising risks isolating better aces or higher diamond draws.

King-high with no pair or draw facing a bet and a call; not worth continuing on this board.

Two pair on a draw-heavy board is strong enough to bet for value and charge diamond draws rather than give a free card. A 500 bet into 700 keeps worse aces and one-pair hands in while building the pot.

Suited connector in position, cheap price to see a flop; no need to raise here.

AJo is strong three-handed and the button only limped, so I isolate to 4bb to build the pot and take the initiative before the big blind acts.

Queen-four offsuit is far too weak to defend the big blind against a raise, especially out of position. Calling 300 to chase a dominated hand loses more in the long run than folding.
