Hold'em table

Q7o is slightly below the standard 3-handed button opening range threshold, making it a clear fold.

Heads-up in the small blind, A6o has solid equity against the big blind's range. A min-raise builds the pot with an ace and applies pressure.

With 5-high connected cards, calling the small raise from the big blind is a reasonable, inexpensive defense against the small blind’s wide range.

I have the nut flush draw with backdoor straight potential, so a continuation-bet semi-bluff builds the pot when called and often wins outright via fold equity, especially out of position.

A low pair with a weak kicker is unlikely to hold up against a sizable flop bet on a king-high board. The backdoor flush possibility is not enough to justify calling.

A9s is a strong suited ace on the button in 3-handed play; raising for value and position with a standard 3x open.

K♦2♠ is too weak to continue against a button raise, especially with the big blind still to act.

Q5o is too weak to defend out of position against a 3x open from the button.

K6 offsuit is a marginal hand, but on the button in a three-handed pot it is strong enough for a small open raise. A raise to 250 applies pressure to the blinds while keeping the risk controlled.

75s is too weak to flat or 3-bet from the small blind against a 2.5bb button open, especially with the big blind still to act.

AK is a premium hand and I have position disadvantage postflop, so I 3-bet to build the pot with a hand that dominates their likely raising range and to take initiative.

K6 offsuit is too weak to continue against the big blind’s three-bet, even with position. I’ll fold and avoid putting in more chips.

On the button in a 3-handed game, A2s is a standard profitable open raise to 2.5x to take initiative in position.

K9s is too strong to fold against a wide 3-max button open, but calling out of position invites a squeeze from the big blind. A 3-bet to ~3x builds fold equity while keeping risk manageable at 100bb.

KJo offsuit is dominated too often against a button open followed by a substantial small-blind 3-bet, and calling leaves me out of position with poor realization. Fold rather than continue at this price.

Calling in position with A2s against the SB 3-bet given good playability and implied odds.

I completely missed the A-Q-Q flop with K-high, and bluffing into an opponent who called my 3-bet on an ace-high board is unprofitable. Checking behind keeps the pot small and preserves chips for a better spot.

Holding top pair with a weak kicker on a paired board, checking behind in position controls the pot and realizes showdown value against the 3-bettor's range.

I have king-high only on a paired board against an opponent who called a 3-bet preflop; betting has little fold equity and checking keeps the pot small with no showdown value invested.

I have top pair with a weak deuce kicker on a paired board; checking behind controls the pot and preserves showdown value.

We hold top pair with a weak kicker on a paired, monotone river. Checking behind allows us to showdown against missed holdings and pocket pairs without risking a call from better Aces.

K9s is a playable suited hand and I have position on both blinds in a 3-max game, so a standard 3x open-raise builds the pot while retaining the initiative.

Q2 offsuit is too weak to continue from the small blind against a button raise, especially out of position with the big blind still to act.

83o is far too weak to defend out of position against a 3bb open.

A6 offsuit is a reasonable button open in a three-handed game. Raise to 2.5 big blinds to apply pressure while keeping the pot manageable.

Holding 85 offsuit from the small blind against a button open is an easy standard fold.

Queen-six offsuit is far too weak to defend against a 2.5bb button raise out of position; folding loses only the blind already committed.
