Hold'em table

King-eight suited is a solid button open; raising for position and fold equity with a standard 2.5x sizing.

T5s is a marginal but playable BB defend versus a 2.5bb button open; the price is good enough to call rather than fold or turn it into a weak 3-bet.

I have a heart flush draw plus some straight outs but no made hand, out of position on an ace-high board. Checking keeps the pot small and lets me realize equity before committing more chips.

I missed the A-high flop with king-high only, and my preflop raise got one caller who checked. Checking behind keeps the pot small and avoids bluffing into a likely ace.

I have a made heart flush on a paired board and act first, so I bet about two-thirds pot for value rather than give a free card.

I only have K-high with a mediocre flush draw (8h); calling 350 into 900 needs ~28% equity but I have ~20%, and when a heart lands my flush is often dominated by higher hearts in seat_3's betting range. Folding is cheapest.

Cheap price to see a flop with a suited hand on the button in a 3-handed pot.

Q5o is too weak to continue out of position after the button limps, with the big blind still to act. Folding saves the extra half-blind rather than playing a dominated hand multiway.

Q5 offsuit is too weak to build a pot, and checking as the big blind lets me see a free flop heads-up against a limper.

Q-high with no draw on a coordinated board heads-up; checking is free and I can fold to pressure rather than invest chips.

Villain signaled a miss; a small continuation bet with backdoor flush/overcard potential can take down the pot.

Pocket queens are a premium hand on the button, so I raise to 3x the big blind to build the pot and take the initiative before the flop.

6d2c is one of the worst hands in hold'em and I'm out of position facing a 3x raise from the button. Folding loses only 50 chips versus calling 250 with almost no equity or playability.

K7 offsuit facing a 3x raise from the button isn't worth defending; folding to preserve chips.

Queen-two offsuit is far too weak to play even from the button in a 3-handed game; folding preserves chips for better spots.

Only 50 more to call heads-up with a live connector hand; cheap price to see a flop.

74o is too weak to raise, and checking is free after the small blind just completes.

Bottom pair with weak kicker on a King-high board; checking to control pot size and see a free card against two players.

4c7h has no pair and no draw on K86 with two spades, so checking back is free and avoids bloating a pot I am unlikely to win.

I have bottom pair at best with no draw; checking keeps pot small and avoids bluffing into two live opponents.

I have only a weak gutshot with no pair or flush draw, and the pot is tiny after passive checks. Checking keeps the price right and avoids bloating a hand with little showdown value.

I have two pair (aces and sixes) which is likely ahead given the checked-down action; betting small extracts value while limiting risk.

I have 7-high with no pair or draw on a paired ace board, so calling a river bet is a clear loss. Folding preserves the rest of my stack.

Q9 suited on the button is strong enough to raise for value and to apply pressure on the blinds.

94 offsuit is too weak to continue against a button raise, especially out of position with the big blind still to act. Folding avoids putting more chips in with a dominated hand.

Q4o is too weak to open first-in from the button with two players still to act, so folding preserves the full stack.

T4s is a weak dominated hand out of position against the big blind; folding the small blind and saving 50 chips is the clean play.
