Hold'em table

I have suited connectors on the button and want to build the pot while isolating the blinds. A 3x open is a standard sizing that applies pressure and gets value from weaker hands.

8d3d is a weak, dominated hand out of position in the small blind, and the button's 3x raise plus a live big blind behind make calling unprofitable. Folding is the clear play.

I have a suited queen in the big blind and am getting good pot odds to call the small raise, so I will see a flop and play postflop.

I have top pair with a good kicker on a dry paired board, so I should bet for value and protection against overcards. A modest continuation-size bet around half pot is appropriate.

Seat 3 raised to 300 on a 9-2-2 flop, representing a strong hand like a set or two pair. My 7s-Js is too weak to continue against a raise and I have no backdoor draws.

AQo is a premium 3-handed button hand; raising to 300 builds the pot with position and pressures the blinds.

7-4 offsuit is too weak to continue against a 3x button raise, especially out of position. Folding preserves chips for better spots.

9c6c is too weak to call a 3x raise from the button, especially with only one opponent remaining. Folding preserves my stack for better spots.

T4o is a weak offsuit hand with poor postflop playability, and calling out of position against the blinds is not profitable. Folding preserves my stack for better spots.

With 2h8h and a folded button, I'm out of position and facing a raise to 100 from the big blind. The pot odds don't justify continuing with this weak suited hand, so folding preserves my stack.

I hold Qc 4d, a weak offsuit hand that is not strong enough to call a 100 big blind raise from the big blind. Folding preserves my stack for better opportunities.

84o is too weak to continue out of position, even with 3:1 pot odds; folding avoids marginal postflop spots.

72o is the weakest starting hand and offers poor playability even with position; folding avoids investing chips with very low equity.

Calling 50 to see a flop offers good pot odds with K4o heads-up, and folding would be too weak given the cheap price.

I am in the big blind with a weak offsuit hand and no one has raised, so checking keeps my costs low and lets me see a flop cheaply.

With two pair but a paired ace board, checking keeps the pot small and avoids value-cutting myself against a possible ace or better kicker. I can reassess on the turn.

Board is paired Aces with a weak kicker; my hand is marginal and I want to control pot size and avoid bluffing a likely strong hand.

The board is paired with two Aces, and I hold the third Ace, giving me a strong set. Checking keeps the pot controlled and avoids scaring out a bluff from the small blind.

I have a strong pair of aces with a king kicker, and my opponent has checked all streets, so I bet for value.

Top pair top kicker on a paired board is strong enough to call a small river bet; opponent's sizing is modest and I want to deny them a cheap showdown bluff.

K9o is strong enough to raise first in from the button, so I make a standard 3x big blind isolation raise to try to take the pot now or play in position.

I hold 3d Tc, a weak offsuit hand. Facing a raise to 300 from the button, calling 250 more is too expensive for such marginal equity, so folding is the correct play.

7-5 offsuit is too weak to defend out of position against a button raise, even with decent pot odds. Folding avoids playing a dominated, low-equity hand postflop.
