Hold'em table

Button open with suited connectors 45s; a 2.5bb raise builds the pot with a playable hand and position.

K2 offsuit is far too weak to defend the small blind against a button raise, with the big blind still to act. The dominated-kicker risk and playing out of position postflop make folding clearly best.

J8s is a standard defend from the big blind against a 2.5bb button open, offering good playability and favorable pot odds.

Checking to the preflop aggressor on a paired dry flop with jack-high and backdoor equity.

I completely missed this dry paired flop, but as the preflop raiser a small c-bet can fold out much of the big blind's checking range.

Holding Jack-high with no flush draw and minimal backdoor equity on a paired board, folding to the flop continuation bet out of position is the standard play.

A9 suited is a strong opening hand three-handed, and raising from the button builds the pot with position while putting pressure on the blinds.

T2o is a very weak hand out of position facing a button open, making it an easy fold.

J9o is too weak to continue out of position against a button open after the small blind folds. Folding avoids paying 200 more with a dominated offsuit hand.

J9o is a profitable open from the button in 3-handed play to attack the blinds with position.

Q5o is too weak to continue against a button open; folding avoids paying 150 with a dominated offsuit hand.

K8o is a standard button open in three-handed play, so I raise to 2.5bb to take the initiative and fold out worse hands.

2d4d is far too weak to call a 2.5x raise out of position, especially with the big blind still to act behind me. Folding preserves chips for better spots.

With pocket threes in the big blind facing a button open and getting attractive pot odds of 150 to win 400, calling to set-mine and realize equity heads-up is standard.

I have an underpair out of position against the preflop raiser on a Q-high board, so a standard check is best.

As the preflop raiser in position on a dry Q94 board, a small c-bet pressures the checked range and can fold out missed ace-highs and weak pairs. K8 has little showdown value, so taking the pot down now is better than checking.

Holding an underpair of threes on a Q-9-4 rainbow flop with minimal equity and no redraws makes this a straightforward fold facing a continuation bet.

K7s is playable from the button three-handed, and a standard 3x open leverages fold equity plus position against both blinds.

A8s is a strong suited ace in a three-handed dynamic facing a button open; three-betting builds the pot and takes the initiative from out of position.

QJo is dominated too often by a 10.5bb small-blind three-bet, and calling 9.5bb out of position is a poor price. Folding avoids a bloated pot with a marginal offsuit broadway.

K7s is far too weak to call a 3-bet at 100bb depth; I'm dominated whenever I hit a king and lack the equity to justify paying 750 into 1450 against a strong SB range. Folding is clearly best.

Open-raising with A7o on the button in a 3-handed game is standard for applying pressure and stealing blinds.

Pocket fours have enough equity and set-mining implied odds against a 2.5x button open to flat from the small blind.

A6 suited plays fine in position against a min-raise; calling keeps the pot small and preserves fold equity for future streets without bloating an unraised pot out of the blinds.

Pocket fours are an underpair to both the jack and king, so I have little reason to bet into two opponents. Checking keeps the pot small and lets me see the turn for free.

A6-high missed the KJ3 flop; three players saw a raise preflop, so checking to realize equity cheaply is best.

In a three-way pot on a connected King-Jack flop, bluffing with Ace-high and no strong draw has low success, so checking back for pot control is prudent.

Pocket fours are an underpair to the king and jack on a multiway turn, so I check to realize showdown value rather than bet into two opponents.

Everyone checked twice, so I'll take a cheap stab with ace-high; fold equity is decent and I can easily fold if raised.

I have Ace-high with no draw on a coordinated board facing a bet and a player still left to act behind me, making this an easy fold.

Pocket fours is an underpair with no draw on a K-J-9 board, and a turn bet after the flop checked through is too often a made hand. Calling 400 needs more equity than this hand reliably has.
