Hold'em table

On the button three-handed, 78o is a standard open-raise for fold equity and positional initiative; raising to 3x applies pressure on the blinds without risking much.

T5o is too weak to continue against a button open, especially out of position with the big blind still to act.

With pocket threes in the big blind getting 2.25 to 1 pot odds against a standard button open, calling is standard to set-mine and realize equity.

I have a weak underpair on an Ace-high flop out of position and should standardly check to the preflop aggressor.

As the preflop raiser on a dry ace-high flop, my range is perceived as very strong while my actual 7-high has no showdown value, so a half-pot continuation bet relies on the big blind's wide check-call range folding often enough to be profitable.

I hold an underpair on an ace-high board with no backdoor equity, making an easy fold facing a continuation bet.

Jack-ten offsuit is a standard button open in three-handed play, so I raise to 2.5 big blinds to take the initiative and fold out weaker hands.

Nine-six offsuit is far too weak to defend out of position against a button open.

I only need 150 more to call with the pot offering about 2.7:1, and K5o has roughly 40%+ equity against a wide 3-max button raising range, so defending the big blind is cheaper and more profitable than folding despite being out of position.

I have a gutshot to the Broadway straight (any Ten) plus a king overcard on a paired board, but no made hand worth betting. Checking keeps the pot small and lets me see a free turn card in position heads-up.

I have trip jacks on a queen-high paired board and the big blind checked, so I bet about two-thirds pot for value from queens, weaker jacks, and draws.

King-high with no draw on QJJ is nearly worthless against a preflop raiser who barreled the flop; folding is cheapest.

65 offsuit is too weak to open raise from the button even in a 3-handed game.

Heads-up against only the big blind, A-high with a decent kicker has strong equity versus a random hand, and raising builds the pot while I'll be out of position postflop. A standard 3x open applies pressure and often wins the blinds outright.

K2o is too weak to continue against a 3bb open even with position; the king is often dominated and the deuce adds little equity.

Q8s is well within a button opening range in 3-handed play, and raising in position applies pressure on both blinds while retaining fold equity and initiative.

J9s has enough equity and implied odds against a wide button open to call 2.5bb from the small blind; I can fold if the big blind squeezes.

T2o is a very weak hand that plays terribly multiway out of position, making an easy fold even getting pot odds.

Jack-nine has no pair, draw, or backdoor equity on an ace-king-three flop, so there is no value in betting into the preflop raiser. Checking keeps the pot small and preserves the option to fold to aggression.

As the preflop raiser on an A-K-x flop, my range is favored and the SB caller's check is often a hand that missed; a half-pot continuation bet generates good fold equity, and my backdoor spade/straight equity gives me a little recourse if called.

Jd9d has no pair and no real draw on AK3, and the preflop raiser's flop bet is likely to be ahead. Folding avoids putting more chips in with a hand that rarely improves to the best hand.

Q7 offsuit is too weak to open from the button in three-handed play, and calling would leave me dominated too often. Folding preserves my stack for better spots.

Q7o is slightly too weak to open or complete profitably from the small blind against the big blind, making fold the standard play.

On the button in 3-handed play, K5s is a standard open-raise to steal the blinds and realize equity in position.

Q8s out of position against a button raise with the big blind still to act is too weak to call or three-bet profitably; folding preserves chips for a better spot.

A3s has enough suited-ace equity and playability to call a button min-raise from the big blind, but it is too weak and dominated to 3-bet out of position.

Bottom pair with an ace kicker is too weak to lead into the preflop raiser on this flop. Checking keeps the pot small and lets me react to their action.

Top pair with a weak kicker plays well as a check back for pot control and to keep the opponent's dominated range in.

I have nines and threes with an ace kicker on a paired board, which is showdown value but vulnerable to any king or nine. Checking keeps the pot small out of position and avoids building a pot I may not win.

I checked back top pair on a dry flop and the board paired on the turn. After the opponent checks again, betting half pot targets value from lower pocket pairs and weaker made hands.

Bottom pair of threes with an ace kicker is too weak to continue against a turn bet on a paired board with a king; pot odds do not compensate for how often I am dominated.
