Hold'em table

On the button with a playable hand in a 3-handed pot, raising to 250 to take initiative against two players who haven't acted yet.

Seat 1 raised to 250 with me in the small blind holding 3h-Ad, which is too weak to continue against a raise from the button. Folding preserves my stack for better spots.

6-2 offsuit is too weak to continue against a button open; folding is the highest-EV option.

I have a weak offsuit hand (Ts3c) and the pot odds don't justify calling a raise from the button. Folding preserves my stack for better opportunities.

Button folded, so this is heads-up versus the big blind with AQo. Raising to 3bb builds the pot with a strong hand and denies a free flop.

5-7 offsuit is weak, facing a raise heads-up out of position with no pot odds worth calling.

A3s is a standard button open in three-handed play; a small raise builds the pot with position and suited-ace equity.

Q9 offsuit from the small blind facing a raise plus a big blind still to act is not worth continuing; folding preserves chips.

With 9c7d, I have no pair and poor connectivity. Facing a raise to 250 after the BB posted, the pot odds and hand strength don't justify continuing.

K2 offsuit is weak from the button facing a raise scenario setup; not worth investing here, folding preserves chips for better spots.

I have a pocket pair and want to build the pot or isolate the big blind with a raise. 300 is a standard small raise that keeps the pot controlled while applying pressure.

A2o is too weak to defend against a raise; the ace is often dominated and the kicker plays poorly.

Calling 100 with Th-9h in position is reasonable; I want to see a flop and play post-flop rather than fold or raise with a speculative hand.

52s is too weak to continue out of position after the button limps, even with a cheap completion, because postflop realization is poor and the big blind can still raise.

K9 offsuit is a marginal hand; with only one limper and no raise, I check my option in the big blind rather than raising.

King-high with no pair on a paired board; checking to control pot size and see a free card.

The board is paired with 7s and I hold Th9h, giving me a backdoor flush draw and gutshot to an 8. Checking keeps the pot small and lets me see how seat_1 plays before committing more chips.

King-high with no pair and no draw; checking is free and I'm behind most hands that would bet, so I'll see the river cheaply.

Board is paired with an Ace and I hold a Ten-high with a gutshot to a straight; checking keeps the pot small and avoids building a big bluff catcher on a scary turn card.

King-high with no made hand and no draw completed; checking is free equity with no fold value to bet.

The board is paired with an Ace on the river and my hand is a weak Ten-high. With no draw completed and the opponent checking, I have little value and should minimize losses by checking behind.

JTs is a strong button open; a 3x raise takes the initiative and builds the pot with a hand that plays well postflop.

Q2 offsuit is a weak hand facing a raise from the button; folding is correct here.

My hand is King-high with a deuce kicker, which is too weak to continue against a preflop raise from the button. Folding preserves my stack for better opportunities.
