Hold'em table

On the button 3-handed with Q8o, a standard 3x raise leverages position and fold equity while keeping the pot manageable if called.

AJo is strong three-handed and ahead of a button open, so I 3-bet to 10bb to build the pot and take the initiative out of position.

T6o is completely unplayable facing a button open and small blind 3-bet.

Q8 offsuit is far too weak to call 700 more against a small blind three-bet, and four-betting this hand would just build a big pot with a dominated holding. Folding preserves chips for better spots.

Q7 offsuit is too weak to open from the button into two live opponents, and calling lets the small blind squeeze. Folding avoids a dominated, low-playability hand.

Q6o is too weak to play profitably out of position against the big blind.

Q6o is too weak to open profitably from the button even three-handed.

T2s is weak, but on the button it costs only 100 to see a flop with position on both blinds, so a cheap call is better than folding this suited hand.

98o is playable enough in a three-handed pot, and completing for 50 into 250 is a cheap way to see a flop rather than folding or bloating the pot out of position.

Checking our option with pocket deuces to see a multiway flop for free and set-mine.

I have a weak pair of eights on a king-jack board with two opponents still to act, so checking is the prudent line.

Holding bottom underpair on a board of King-Jack-Eight, checking to see a free turn is standard.

Both opponents checked a limped flop and I have position with T-high air, so a small stab has enough fold equity to be profitable; if called I can reassess cheaply on the turn.

Middle pair with a weak kicker and no real draw is behind too much of a bet on K-J-8 with two spades, and I am out of position with the big blind still to act.

We hold an underpair of twos on a king-jack high board with virtually no equity or drawing potential against the button bet.

T4o is too weak to call or open from the button; folding avoids putting chips in with a hand that plays poorly multiway or as a bluff.

In a blind-versus-blind spot, Q7s is well ahead of an open-folding range and plays well as an aggressive steal against the big blind.

T2o is dominated against a 3x raise from the small blind; calling 200 with trash out of position has no edge, so folding is clearly best.

J5s is on the weaker fringe of the button opening range in 3-handed play, making folding a standard and clean disciplined decision.

Ten-deuce offsuit is too weak to play out of position against the big blind, even at the cheap price of 50; folding avoids dominated postflop spots with a hand that rarely connects strongly.
