Holdem table

Calling with Q9s in position is reasonable; I can see a flop and potentially realize equity without committing more chips preflop.

A4o has enough equity to call the small blind completion in a 3-handed pot; raising out of position with a marginal ace risks bloating the pot.

I have a weak offsuit hand with no need to build the pot out of position, so I take the free flop.

I have ace-high with a gutshot to the nut straight on a coordinated board, but no made hand and I'm out of position. Checking controls the pot and keeps the option to call or fold based on action.

My hand is weak with only a gutshot straight draw (needing a Jack) and no pair. Checking gives me a free card to try to hit the straight while avoiding unnecessary risk against opponents who may have stronger hands.

The board is coordinated with a straight draw, and my hand is marginal. Checking keeps the pot small and allows me to see a turn card without committing more chips.

I hold the nut Broadway straight (A-K-Q-J-T) on the turn, so I am betting for value and to charge any flush draws or sets.

Seat 3 folded to the turn raise, leaving a heads-up pot. My 9h Qs is a weak gutshot to a 9 and has no pair; calling 300 into a 600 pot is a bad price. Folding preserves my stack.

7-3 offsuit is a very weak hand and calling 100 chips out of position against the big blind is unprofitable.

Button folded, and I have a suited T7 in position against the big blind. Calling 50 more gives me good pot odds with playable equity and keeps the pot small.

I am in the big blind with AcJd and the action is on me with no raise. Checking keeps the pot small and avoids putting money in with a speculative hand out of position.

I have a weak draw with no made hand, and checking keeps the pot small while seeing the turn for free.

Board is highly coordinated with two hearts and a King-Queen, and my hand is Ace-high with no flush draw. Checking keeps the pot small and avoids building a big pot with a weak holding.

Board is a four-flush with no pair; my AcJd is a bluff catcher. Checking keeps the pot small and avoids building a big bluff against a likely hand.

The board is a rainbow, unpaired river with no flush or straight completed, and my high-card hand is unlikely to be best; checking avoids building a bigger pot with a weak holding.

I have a decent ace with position on the button, so I raise to take initiative and potentially win the blinds preflop.

9d4c is weak and unsuited, and calling 200 more into a 400 pot with a big blind who raised to 250 is a clear fold. I'll preserve my stack for better spots.

J7o is a weak offsuit hand facing a 2.5x button raise; calling 150 out of position with a dominated, low-equity holding is unprofitable, so I fold.

With Q4o on the button and only 100 to call, the hand is too weak to continue profitably against two opponents who have already invested blinds.

Button folded, so A3o is ahead of a wide big-blind range; raising applies pressure and takes initiative.

Calling 200 into a 400 pot offers good pot odds with A4o, and the opponent's raise from the small blind could be a wide steal attempt. Folding would be too weak given the price, while raising with this marginal hand risks unnecessary chips out of position.

A-high missed the flop, but I raised preflop and a small continuation bet can fold out BB's overcards and weaker hands. I can shut down if called or raised.

KQo is a strong 3-handed button hand, so I raise for value and to take initiative rather than just call from the button.

QJs is strong enough to three-bet from the small blind against a button open, applying pressure and taking initiative while still having good playability if called.

With 6c8h and a 3-bet to 900, my hand is too weak to continue; I'll fold to preserve chips.

KQo has enough equity to continue in position against a small-blind 3-bet, and calling keeps the pot controlled while realizing equity on later streets.

I flopped a full house and should bet for value against an opponent who called a 3-bet and may hold an ace or a big pair.

4-6 offsuit is a weak hand from the button against the big blind's option, and calling 100 chips has poor expected value. Folding preserves my stack for a better spot.

I have 4c 3h, a weak offsuit hand. The small blind (me) faces a 50 call to see a flop with no equity edge, so folding preserves chips.
