Holdem table

AQ offsuit is a strong button open; a 3x raise builds the pot and applies pressure before the blinds.

A9 suited is strong enough to 3-bet the button's open and take initiative, especially with a player still to act behind.

K5 offsuit is dominated and nearly dead equity against a 3-bet after a raise and re-raise; calling 800 into this range is a clear losing play, so folding is the only sensible option.

AQo is strong enough to continue in position against a small-blind 3-bet; calling keeps the pot manageable and realizes equity postflop.

Middle pair with a strong kicker but no draw on a two-flush board; I'll check to control pot size and see what my opponent does.

I have top pair with the ace kicker on a wet board after the preflop 3-bettor checked. A roughly 40% pot bet gets value from worse queens and pairs while charging draws.

I have middle pair (9s) with an Ace kicker, decent enough to continue but not strong enough to raise against a range that could contain top pair or better.

Only a middle pair with an ace kicker on a coordinated board; checking controls pot size against an opponent who has shown continued aggression.

I have top pair with the ace kicker on a checked turn, so I bet about two-thirds pot for value against worse pairs and draws.

Opponent's flop check-raise followed by a big turn bet suggests a strong made hand (flush or straight), while I only hold middle pair with top kicker; the pot odds don't justify continuing against such a strong range.

J7 offsuit is a weak hand out of position facing action; folding preserves chips.

Heads-up after the button folds, K6o has solid equity against the big blind's wide range and I have position postflop. A standard 3x raise builds the pot and applies fold equity.

96o is too weak to defend out of position against a raise; folding preserves chips.

Button with J7o in 3-max is a standard steal spot against two blinds; a 3x open applies pressure and lets me take the pot with position or continue cheaply.

87o is too weak to call a button raise out of position from the small blind, so I fold rather than invest more with a dominated offsuit hand.

34o is too weak to open from the button for a full big blind, so folding preserves the stack.

KJ offsuit is a solid hand heads-up against the big blind after the button folded; raising to build the pot and take initiative.

53 offsuit is far too weak to call 200 more against a 3x raise from the small blind; my equity is well below the required pot odds and the hand plays poorly postflop.

76o is a weak hand and not worth defending from the button facing a raise in a 3-handed pot.

Seven-three offsuit from the small blind against the big blind is the worst spot to invest more chips; calling 50 out of position with no hand worth playing is -EV, so I fold and preserve my stack.

On the button three-handed with a cheap min-raise available, K4o has enough fold equity and positional value to steal the blinds; I can fold cheaply if 3-bet or play fit-or-fold in position if called.

Q6 offsuit is too weak to continue out of position against a button open, so folding is the highest-EV option.
