Hold'em table

On the button three-handed with Q8o, I have position and decent fold equity; a standard 3x open takes initiative and can win the blinds immediately.

AJo is strong enough to 3-bet the button open from the small blind; 900 is a standard size that builds the pot and denies equity.

Holding T6o facing an open and a 3-bet from the small blind is an easy fold.

Queen-eight offsuit has poor equity against a three-bet range that already showed strength by raising to 900 out of position. Calling 600 more risks too much for a dominated marginal holding.

Q7 offsuit is too weak to open from the button for a full big blind; folding avoids dominated spots and poor postflop play.

Q6o is too weak to complete or raise profitably from the small blind out of position.

Q6 offsuit is too weak to profitably open on the button even 3-handed.

Heads-up suited connector in SB plays well; raise to build pot and apply pressure.

62 offsuit is too weak to continue against a small-blind raise, so folding is the clear choice.

On the button in a 3-handed game, one big blind is a cheap price to see a flop in position with a suited ten-high that can flop pairs and draws; folding is too tight at these pot odds.

98o is speculative but the price is right: 50 more into 250 gives about 5:1, so I complete and see a flop rather than raise a weak offsuit hand.

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

Middle pair with a weak kicker on a king-jack board is too thin to lead multiway out of position, so I check and realize equity.

I have an underpair with negligible showdown value on a king-high board in a multiway limped pot, so checking is standard.

Both opponents checked through a limped pot, which often signals weakness; a half-pot stab with ten-high on the button needs only ~33% fold equity to profit, and I can simply give up if called or raised.

Bottom pair with a weak kicker on K-J-8 two-tone, facing a flop bet with the big blind still to act. Not enough equity or showdown value to continue.

I have an underpair of deuces on a board with two broadway cards and a bet from the button, leaving me with negligible equity to continue.

T4o is too weak and disconnected to open from the button even three-handed; folding avoids playing a dominated hand out of position postflop against two live blinds.

In a blind versus blind spot after the button folded, Q7s is a strong candidate to attack the big blind with an open-raise to 3bb.

T2o is nearly the worst hand I can hold and I'm facing a 3x raise from the small blind with 200 to call. Calling gives dominated, unplayable equity out of position, so folding is clearly best.

J5s is slightly too weak to open from the button in a standard 3-handed structure. Folding preserves chips.

T2 offsuit heads-up out of position for 50 more is not worth calling; fold and wait for a better spot.
