Hold'em table

Button with suited one-gapper 9s7s in 3-handed game; raising to 2.5x to pressure blinds and build pot with a hand that flops well.

8-3 offsuit is one of the weakest hands. Calling 200 more out of position against a button raise with the big blind still to act is not profitable, so I fold.

KTo is a reasonable hand to defend the big blind against a min-raise from the button; calling keeps the pot small while seeing a flop in position relative to the blinds.

I have king-high with a gutshot/backdoor draws on a paired board; no made hand strength to bet, so I check and control pot size.

I raised preflop and got a call; this board is dry and paired, so a continuation bet represents a jack or overpair. I bet half-pot to pressure the caller into folding many hands that are currently ahead of my 9-high.

KT high on a J-J-2 board with no pair or draw; small flop bet but not worth continuing against a likely jack or overpair.

Q2 offsuit is a weak hand in a 3-handed pot. Folding on the button avoids a marginal call, though it gives up a small amount of equity.

Weak offsuit low cards (3-6) with only one opponent left to act after me; not worth completing the small blind.

3c7h offsuit is a weak, unconnected hand with no equity to justify calling from the button against two active players; folding preserves chips for better spots.

J4o is a weak hand out of position; calling from the small blind is unprofitable.

J3o is too weak to profitably raise from the button, and calling offers no equity edge postflop.

K8 offsuit in the small blind heads-up against the big blind is a playable hand, and completing costs only 50 more for a good price, so I call instead of raising or folding.

AT is a solid hand heads-up vs a limper; raising for value and to build the pot while isolating.

K8o out of position facing a 3.5x raise from the big blind, with a pot that's already 450 and 250 more to call. The hand is weak and dominated often, so folding is the disciplined choice.

QJo on the button in a 3-handed game is a playable hand with decent equity. Calling 100 to win a 250 pot is a cheap way to see a flop, and I keep position.

Cheap price to see a flop from the small blind with a speculative hand; folding here is unnecessary given the pot odds.

I have a weak hand (9s5o) and no reason to raise; checking lets me see a flop for free.

No pair or draw with 6-9 on an Ace-high board; checking as first to act is the safest, cheapest option.

We have bottom pair with a weak kicker on an Ace-high board. With two opponents still to act, building the pot out of position is risky. Checking controls the pot size and lets us see the turn cheaply.

On the button with a gutshot straight draw (K needed) and two overcards to the 5, after both opponents checked. A small bet of 200 into the 300 pot can win the pot now and gives me equity if called.

Gutshot draw at best on a dry board facing a flop bet out of position; not worth continuing against a button raise.

We have bottom pair with no draw on an A-T-x board facing a bet from the button. Out of position and unlikely to improve, folding is best.

Jd7h offsuit is a weak hand not worth playing from the button facing a raise-call dynamic; folding preserves chips.

9d6c is a weak hand out of position, and calling 50 more just to see a flop OOP with a bad hand is -EV. Folding preserves chips for better spots.
