Holdem table

QJs suited is a strong 3-handed button open; I raise for value and fold equity with position, keeping the sizing standard at 3x.

Jack-seven offsuit is too weak to continue out of position against a button open, especially with the big blind still to act. Folding preserves chips for better spots.

7h Tc offsuit is weak against a button raise with only one opponent left; folding avoids investing more with a low-equity hand.

AJo is a strong button open in a three-handed game, so I raise to 3bb to build the pot and take the initiative rather than flat the big blind.

K3 offsuit facing a 3x raise from the button with a call still needed from BB behind is not worth defending; folding preserves chips for better spots.

Q7o is dominated by better queens and plays poorly out of position against a 3x raise. Calling requires ~31% equity, but realized equity with this hand is well below that, so folding is best.

K4 offsuit on the button facing a raise-limp scenario is weak; folding preserves chips since it's not worth defending out of position value with a marginal hand.

Pocket sevens heads-up against only the big blind is a clear raise for value and fold equity; a standard 3x build keeps the pot manageable while denying a free flop.

Q9o is marginal, but I have position heads-up and am getting 2:1 against a likely wide small-blind open, so a call is better than folding.

As preflop aggressor on a dry K-high board, a half-pot c-bet has good fold equity heads-up; my 77 beats A-high and can fold out wider BB call ranges. If raised, I can let go cheaply.

Queen-high with no pair and no draw on a king-high flop is too weak to continue against a half-pot bet.

On the button in 3-handed play, I can open wide; 68o has poor equity but position, and a 2.5x raise pressures the blinds to fold or lets me play postflop with initiative.

Pocket queens is a premium hand against a button open, so I three-bet to 1000 to build the pot and play for value out of position.

Q3o facing a big 3-bet is too weak to continue, easy fold.

6-8 offsuit is far too weak to call a 3-bet for 750 more, and 4-betting this hand would just burn chips. Folding preserves my stack for better spots.

J4o is too weak to open first-in from the button in this three-handed spot, so folding preserves chips.

Weak offsuit 8-6 with only one opponent left; not worth completing the small blind out of position.

Heads-up against only the big blind, 50 more into a 150 pot is cheap with a suited connector that can make flushes, straights, or disguised two pair. Calling keeps the pot small while retaining playability.

92s is too weak to raise for value against a limp, and I can see the flop for free in position, so checking is best.

Bottom pair with a weak kicker has some showdown value but is too thin to bet into a queen-high board after the opponent checks. Checking keeps the pot small and realizes equity cheaply.

I've paired the board with my 2 and heads-up versus a likely wide BB, a small stab can win the 200-chip pot outright with little risk.

Bottom pair with a weak kicker is not worth calling a pot-sized turn bet; I am often behind a queen, an eight, or a strong draw and lack the equity to continue.
