Hold'em table

On the button 3-handed, 67o is a standard wide open; raising 2.5x builds the pot with position and fold equity rather than limping into a multiway flop.

A7o out of position versus a button open is too weak to call or 3-bet, especially with the big blind still to act.

In 3-handed play, A8o has plenty of equity against a wide button opening range, and we are getting attractive pot odds to defend from the big blind.

I am out of position against the preflop raiser with Ace-high and a backdoor nut flush draw; checking my entire range here is standard.

As the preflop raiser on a dry KK6 board, a small continuation bet folds out A-high and small pairs, and my pair of sixes still has showdown value if called; I can cheaply fold to a check-raise.

We hold Ace-high with the Ah backdoor nut flush draw on a paired board where the button c-bets at high frequency, getting over 3:1 pot odds.

I am out of position with Ace-high on a paired turn board; checking to see what the button does is the standard line.

My kings-and-sixes two pair is behind most king-x hands that would check-call the flop, and only gets value from rare low pairs. Checking back keeps the small pot controlled while I retain showdown value and can reassess on the river.

Holding Ace-high with the nut flush blocker on a board with paired kings and three hearts, we have decent showdown value against missed draws and little value in betting.

I hold two pair (kings and sixes), but the villain's passive check-call line means a river bet is mostly called by better KX, 77+, or a completed flush, while small pairs may fold. Checking realizes my showdown equity with no risk.

J4o is too weak to open from the button for a full big blind; folding avoids a dominated, low-playability hand.

J4o has poor playability out of position against the big blind, making a fold the most standard and disciplined play.

86 offsuit is too weak to open profitably from the button even in 3-handed play.

KQs on the button in a 3-handed game is a strong value-raising hand; I open for 3x to build the pot with position and apply pressure on the blinds.

K2o is too weak to continue out of position against a button open; folding avoids a dominated, low-equity spot.

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

Pocket threes on the button are a clear open in three-handed play. A raise to 300 builds the pot and takes the initiative before the blinds act.

Holding T6 offsuit in the small blind against a button raise is an easy fold out of position.

Heads-up versus a button 3x open, my Q-To plays well as a light 3-bet: I apply pressure with fold equity while holding enough equity to continue if called.

Pocket threes are a marginal but playable call in position against a single 3-bet; the price is small enough to set-mine with position and a deep stack.

I flopped top pair with Q-T on a two-heart board; betting ~65% pot charges draws and worse queens while building the pot. I can fold to heavy aggression since AQ/KQ dominate me.

Pocket threes are an underpair with no flush draw on a queen-high flop against a preflop 3-bettor who is c-betting. Calling needs more equity than two set outs provide, so I fold.

42 offsuit is far too weak to open or play from the button, making folding the standard and most profitable play.

3-7 offsuit is one of the worst starting hands and I'm out of position against the big blind; the tiny preflop equity edge doesn't justify playing a hard-to-realize hand postflop.
