Hold'em table

K3 offsuit is a weak hand from the button facing a raise to call; folding preserves chips.

Button folded, so I am heads-up versus the big blind and only need to complete for 50 into 150. J2s has enough suited equity to continue rather than fold or inflate the pot.

I am in the big blind with Q♠ A♥ and the action is on me with no raise. Checking keeps the pot small and lets me see a flop cheaply with this strong hand.

Jack-high with no pair and no real draw on 8c Th 3h; checking keeps the pot small and realizes equity for free.

Checking keeps the pot small with a mediocre hand on a dry board and avoids building a bigger pot out of position.

Bottom pair with a weak kicker and no flush draw is not strong enough to bet into the big blind on the turn, so I check and keep the pot small.

Checking keeps the pot small with a weak showdown hand on a scary board where the opponent may have a strong draw or pair.

Bottom pair with a jack kicker has some showdown value but is too weak to bet for value, and a bluff is unlikely to fold out better hands after two streets of checks. Checking realizes the hand cheaply.

Board is a rainbow 8c-Th-3h-2h-Qd with no obvious flush or straight draws; my QsAh is a weak high-card hand with backdoor flush potential that missed. Checking keeps the pot small and avoids building a bigger pot with a marginal hand on the river.

6s3d offsuit is too weak to call or raise from the button against two live blinds. Folding preserves the full stack for better hands.

I have AcJc, a playable suited hand. The small blind has only 50 invested, so a 300 raise builds the pot and applies pressure while I still have 9950 chips behind.

Heads-up with an ace, I'll 3-bet to apply pressure and build a pot with initiative.

Seat 1's 900 raise with Ac is suspicious; I'll 3-bet to 1500 to apply pressure and test their strength with my suited Ace.

Facing a preflop 4-bet with A4o, my equity is too weak to continue for another 600 out of position; folding preserves my stack for better spots.

I hold Jd 8s on the button with no prior investment. The small blind opened to 50 and big blind to 100; calling 100 with this weak hand is unprofitable, and I have no read to justify a bluff raise. Folding preserves my stack.

A6s suited ace plays well heads-up against BB; raising to build pot and take initiative.

Jack-ten suited is ahead of a wide small-blind open and plays poorly out of position as a flat, so I 3-bet to 900 to take the initiative and deny equity.

Facing a big 3-bet from the big blind with only A6 suited, the pot odds don't justify continuing against a range likely to be strong.

AJ offsuit is a strong hand on the button in a 3-handed game; raising to 250 builds the pot and applies pressure.

J5 offsuit is too weak to call a button open out of position with the big blind still to act.

I hold 3s 8c, a weak offsuit hand. Facing a raise to 250 with only 150 to call, the pot odds don't justify continuing with this speculative hand.

25o is too weak to call or raise even on the button in a three-handed pot, so folding is the highest-EV option.

I have Ace-high with a backdoor flush draw, which is decent for a call given the opponent only has 50 invested. Folding would be too weak, and raising is risky without more information.

Heads up with a live ace, I'll raise to build the pot and apply pressure on the limper.

I have As8h, which is a weak hand out of position facing a raise to 350. The pot odds and implied odds don't justify calling with this speculative hand, so folding is the disciplined play.

I hold Kh 2c on the button with no callers yet; the pot odds don't justify a bluff raise, so folding is the most chip-efficient play.

9-4 offsuit is weak; facing a call with only heads-up equity vs BB, folding is best given poor hand strength.
