Hold'em table

Pocket eights play well 3-handed; a standard raise from the button builds the pot with position and can win it preflop.

94o from the small blind facing a 3x button open with the big blind still to act is a clear fold; it is out of position with poor equity.

Facing a 3x open from the button, T6s is slightly too weak to defend out of position.

42o is too weak to open, even from the button in 3-handed play, so folding is the clear choice.

Q4o is too weak to complete out of position against the big blind.

6h 2c is well below any reasonable button opening range in 3-handed play. Standard fold.

Blind vs blind, Q5o is a reasonable small-blind open against a single big blind; raising to 3bb applies fold equity and avoids playing out of position in a limped pot.

Defending the big blind in position against a small blind open with QTo getting 2:1 pot odds.

This ace-high flop favors my preflop raising range, so a small continuation bet can fold out the big blind's weak hands. My queen-high has almost no showdown value, so betting is better than giving up.

I have queen-high with only backdoor draws on an ace-high board, facing a c-bet.

In 3-handed play the button is first to act, and T6o is a reasonable steal hand against only two blinds. A small open to 2.5bb puts pressure on both of them cheaply.

Q4o is far too weak to defend from the small blind against a button open.

K7o in the big blind getting 150 to call into a 400 pot is cheap; defend and see a flop rather than fold a king-high.

I have king-high only on a J-high board with no draws; checking keeps the pot small and avoids building a hand I can't win at showdown.

As the preflop raiser in position on a dry J-high board, a small c-bet with bottom pair plus a backdoor flush draw gets value and protection, and it folds out overcards.

King-high with no pair on J62 two-tone board facing a flop bet from the preflop raiser; little equity or fold equity, so folding is cheapest.

Q8o is at the bottom fringe of playable hands on the button in 3-handed play; folding cleanly avoids marginal spots.

Suited connector heads-up vs BB; raising for fold equity and position, cheap enough to continue if called.

Blind vs blind, SB raises to 3x; I get 2:1 (200 to win 600) with K3o in position, which is a standard defend against a wide SB range.

I missed the J-high flop completely with 7s8s; heads-up I can check and fold to pressure rather than invest more.

The small blind checked on a paired, high board, which suggests weakness. A small one-third-pot stab in position can fold out underpairs and missed hands, and King-high keeps some backup equity.

I have 8-high on a wet J-J-Q board facing a bet after two players called a preflop raise. Only fold equity exists here; folding is cheapest.
