Hold'em table

K5 offsuit is a reasonable button open three-handed, and a 2.5 big-blind raise gives me a chance to take the blinds while keeping the pot manageable.

7-3 offsuit is far too weak to defend from the small blind against a button open, especially with the big blind still behind.

KTs in the big blind against a button open to 2.5bb is a clear defend: I'm getting good pot odds with a hand that plays well. Calling keeps the button's weaker hands in, and I can 3-bet some of my other hands instead.

KTc with a backdoor flush draw and two overcards is out of position against the button raiser on a dry low board, so the standard play is to check to the raiser. I can continue against a small c-bet.

King-high has some showdown value on this dry flop. Checking in position controls the pot and avoids facing a raise with a weak hand.

The button checked back the flop, which caps his range. I have the nut-ish flush draw plus two overcards, so a semi-bluff of about two-thirds pot can win the pot now and still has lots of equity if called.

I have an open-ended straight draw and position. The small turn bet is worth calling, with some chance my king is also an out.

King-high has almost no showdown value against a range of weak pairs and ace-high draws. Barreling the queen with a two-thirds pot bet can fold out many of the 9x and small pairs that called the turn.

King-high has little showdown value. The five blocks some straights, and my turn call can credibly represent a straight, making this a reasonable river bluff.

With king-high after missing the club draw, I lose to almost any hand that would raise the river. Re-shoving as a bluff risks too much into what is likely a strong range, so I fold.

5-2 offsuit is too weak to profitably enter with against both blinds from the button in this spot.

Blind vs blind, Q4 suited is a reasonable open from the SB; raising to 3bb applies pressure and avoids playing out of position in a limped pot.

T2 offsuit is too weak to defend against a 3-big-blind raise, even with position after the flop.

On the button in 3-handed play, 75o is near the bottom of the opening range and plays poorly at 100bb deep, so folding is fine.

With 9♠3♠ in the small blind, completing for 50 chips is inexpensive, but the hand is too weak to build a large pot out of position.

T2 suited is too weak to inflate the pot, but we can see a flop for free in this heads-up limped pot.

Middle pair can get value from weaker pairs and draws while charging overcards on this wet flop.

I have a made flush on a coordinated board and should raise for value while charging single-heart hands, sets, and strong king holdings.

Middle pair with a weak kicker is a poor hand to defend against a sizable flop raise, especially out of position on a board with a flush draw.

Pocket aces are the strongest starting hand. A 3-big-blind button raise builds the pot while leaving room for weaker hands to call or reraise.

8h4h is too weak to defend from the small blind against a button 3x open with the big blind still behind.

Getting about 3.25:1 in the big blind against a wide 3-handed button open, T7o has enough equity and playability to defend by calling.

Gutshot plus backdoor flush draw out of position against the button raiser on a board that favors their range; checking keeps the pot small and lets me realize equity, and I can continue against a small c-bet.

Aces are strong on this draw-heavy flop. Betting about two-thirds of the pot gets value from kings, queens, and draws while charging them to continue.

Ten-high with only backdoor draws on K-Q-8. Calling 450 into 1100 would need about 29% equity, and my equity is far below that against a preflop raiser's c-bet.

Fold the weak 4-5 offsuit rather than enter a multiway pot with little high-card value.

T7 suited is a standard open from the small blind in a blind-vs-blind spot with 100bb deep stacks. Raising to 3bb takes the initiative and can win the pot uncontested.

42 offsuit is too weak to defend against a 3x raise, even with position after the flop.

A7o is a clear open from the button in 3-handed play; a standard 2.5bb raise works well against the two blinds.

Pocket jacks are strong enough to three-bet a button open. A larger size accounts for being out of position and discourages the big blind from calling cheaply.

6-5 offsuit is too weak to defend against a large 11bb squeeze in a three-way pot.

A7o is well behind a small-blind 3-bet to 11bb over a button open, and calling 850 into 2300 out of position... well, in position, but it plays poorly against a range heavy in dominating aces. The hand has too little equity and playability to continue profitably, so folding is best.
