Hold'em table

K5s on the button has position and a king-high; a small raise applies pressure and can take the pot down postflop.

7d4c is a weak hand that cannot withstand a 300 preflop raise from the button. Folding preserves my 9950 stack for better spots.

7d4h is a weak hand that doesn't play well out of position. The small blind limped and the big blind completed, so there's no strong reason to continue with such a marginal holding.

Cheap price to see a flop heads-up against the big blind with a live hand; folding here loses value given the pot odds.

72o is nearly worthless; I already have the BB in and can see a free flop, so checking is clearly best.

Top pair with a flush draw on board; betting for value and protection against spades and open-ended draws.

I hold 7h2c with no draw on a J-high board facing a bet; folding is clearly best.

T5 offsuit is a weak hand not worth entering a 3-bet pot or facing two players with; fold from the button.

I have a pocket pair of sixes, which can make a set on the flop. Calling the small blind's 50 chips is cheap and keeps me in the hand without overcommitting preflop.

J5 offsuit is weak; with no raise needed I check and see a cheap flop from the big blind.

I have a pocket pair of sixes and the flop is Ac-4h-Ks, which is a dry board with no immediate threat to my hand. Checking is the safest play to control the pot and avoid building a bigger pot with a mediocre holding.

I have no pair and no draw with J-high on an A-K-4 board, so checking is best with no value to bet and nothing to protect.

Board is dry and unpaired with a King high; my sixes have limited play and I want to control pot size and keep the opponent's range wide. Checking also preserves the option to take the lead on the river if it improves.

I have Jack-high with no pair, weak equity; checking to see a free river is best.

I have a pair of sixes on a paired board with an Ace and King, so my hand is vulnerable to overcards and two-pair hands. Since the opponent checked behind on the turn, checking back keeps the pot small and avoids building a bigger pot with a marginal hand.

Board pairs fours and my Jack kicker likely beats a weak board-only hand; no reason to bet into a dead-looking pot, just check and show down.

5s 6h is a weak hand with limited playability, and calling 100 into a 150 pot from the button leaves me out of position with poor implied odds. Folding preserves my stack for better spots.

9c2c is a weak offsuit hand; folding from the small blind facing a call is fine, no need to invest more with such low equity heads-up against the big blind.

4-7 offsuit is a weak hand not worth playing from the button facing a raise-free pot; folding preserves chips for better spots.
