Holdem table

Q6 offsuit is weak from the button facing a raise-sized pot; not worth continuing in a 3-handed pot with no equity edge.

Heads-up with a suited queen, completing for 50 into a 150 pot needs only ~25% equity, and Q3s has well more than that even against BB's defending range. Cheap call, low variance.

68 offsuit is too weak to raise, and checking is free with no bet to call after the small blind completes.

I flopped trip eights and seat 2 checked, so I bet about three-quarters of the pot for value while keeping worse queens and pairs in.

I flopped top pair (Q with a weak 3 kicker) and face only a 150 bet into 350, giving me great pot odds to see one more street. Calling keeps the pot small since my kicker is weak and a raise would only isolate me against better queens or trips.

I have trip eights on a queen-ten board and the opponent checked, so a modest value bet can get called by queens, tens, and draws.

My Qd gives me two pair (queens and eights) on the Q-8-8-T board; calling 300 into an 800 pot is a good price, while raising would mostly isolate me against better queens, 88, or the J9 straight.

I have eights full of sixes and the opponent checked the river after calling earlier streets, so a modest value bet can get called by queen or ten hands.

A4s suited is a standard button open in 3-max; raising to 3bb applies pressure on the blinds and builds a pot with position.

A4o is too weak to continue out of position against a button open, with poor playability and domination risk. Folding preserves chips for better spots.

Qc2c is a weak offsuit hand facing a 3bb raise from the button; not worth calling out of position.

93o is too weak to open first-in from the button in three-handed play; folding avoids a dominated, poorly-playing hand.

K3 offsuit heads up against a big blind is weak with only one player left; folding avoids committing more chips to a marginal hand.

Weak offsuit low cards (4-3) on the button with a raise to consider isn't needed here; folding preserves chips against two live blinds with no strong hand.

On the button in 3-max, a min-raise to 200 applies pressure on the blinds and lets me play in position if called; I can easily fold to a 3-bet with 8-6 offsuit.

4h2h is too weak to continue out of position against a button raise, so folding is the highest-EV line.

Facing a min-raise from the button with QTo in the big blind, calling is cheap and keeps me in position to see a flop heads-up.

I have only a gutshot with queen-high on a King-high board; checking keeps the pot small and lets me see a free card or react to a bet.

I raised preflop and the K-high flop is unlikely to have connected with the big blind's call-check range, so a ~2/3 pot continuation bet takes the pot down often with my unmade hand; I can easily fold if check-raised.

No pair and only a gutshot draw facing a bet; pot odds are insufficient to continue profitably.

65o is too weak to open from the button in a three-handed pot; folding avoids a dominated, low-equity spot.

9-4 offsuit is weak, and facing a call with only the big blind left to act, folding is better than continuing with a poor hand.
