Hold'em table

JTo is playable from the button; a 2.5bb open builds the pot with position and folds out weaker hands.

With Qc8c in the small blind facing a button raise, a 3-bet to 750 represents strength, allows me to take the initiative, and can win the pot preflop or on the flop, while still having playability with suited cards.

3h6c offsuit is far too weak to defend against a large open and a 3-bet-sized raise out of position.

JTo has enough equity and position versus a small-blind 3-bet to continue; a 4-bet would mostly be a bluff against a strong range.

I have Qc8c, missed the flop on 5s6s6d, no pair or draw. I'm out of position heads-up; checking is prudent to control the pot and see if my opponent bets.

JTo has no pair or draw on a paired board against a preflop 3-bettor, so checking back in position keeps the pot small and realizes free equity.

We have two pair but on a paired and straightening board, our hand is vulnerable and not strong enough to bet for value against a preflop 3-bet calling range. Checking controls the pot and avoids getting raised off our equity.

JTo has only overcards on a paired board against a preflop 3-bettor who checked twice, so checking realizes showdown value without bloating the pot.

I have a pair of eights on a paired board with no draws. My hand has showdown value but is vulnerable to better pairs or trips. Betting would likely only get called by better hands and fold worse ones, so checking to control the pot and see a showdown is the best play.

Jack-high has no showdown value, but a river bluff into the preflop 3-bettor is unlikely to fold out enough better hands. Checking realizes the free showdown.

74o is a very weak hand, even on the button. Folding avoids risking chips with a hand that plays poorly postflop.

Defend the small blind heads-up with an ace despite the weak kicker; the price is minimal.

Pocket threes have value heads-up against a limp, so I raise to 400 to build the pot and take the initiative rather than check.

A8 offsuit is strong enough to defend against a likely wide blind isolation raise, especially at this modest size. Calling preserves its equity without inflating an out-of-position pot.

I have the nut flush draw plus a gutshot and can apply pressure to the preflop raiser. Leading builds the pot when called while retaining strong equity.

I flopped a set of threes and want to build the pot while charging flush draws and worse made hands. Raising to 1800 is a clear value raise rather than a flat call.

I have the nut diamond draw, an open-ended straight draw, and an overcard. Shoving maximizes fold equity while retaining strong equity when called.

I flopped a set of threes and only need to call my remaining stack. Even against a flush draw or two pair I have strong equity, so folding is not an option.

T4 offsuit is a weak button holding; folding avoids entering a pot with poor equity and playability.

23 offsuit is too weak to continue even for a half-blind, especially heads-up against the big blind.

96s is playable as a button open in three-handed; a small raise applies pressure and can take the blinds or see a flop with initiative.

Qd2d is a weak, easily dominated hand out of position with poor reverse implied odds. Facing a button raise from the small blind, folding is the safer choice and avoids losing more than the blind.

Pocket sixes are strong enough to defend the big blind against a button min-raise, especially heads-up with favorable pot odds.

Checking preserves the opponent's wide continuation range and allows for a check-raise on this coordinated flop with bottom set.

I have a pair of sixes on a king-high flop after the big blind checked. A small c-bet can take the pot or get called by worse while keeping the pot manageable.

Bottom set is a very strong value hand on this coordinated board. Raising builds the pot against Kx, overpairs, and draws while charging the spade and straight draws.

Bottom pair with a weak kicker is too thin to continue against a flop check-raise; the price does not justify calling or raising.

In button position with T8o, raising to 200 to steal the blinds; if called or reraised, can easily fold on flop.

K7 suited has sufficient equity and playability to defend the small blind against a minimum button open, especially with the big blind still to act.

K2 suited is too weak to continue out of position against a raise and a call; folding avoids a dominated spot.

I have two overcards to the board’s low ranks, a club flush draw, and a gutshot straight draw. A small continuation bet can fold out unpaired overcards while retaining strong equity when called.

I have T8o, no pair, no draw, and facing a donk bet on a paired board. Fold is best.

Q5 offsuit is too weak to open profitably on the button at this stack depth; folding avoids entering dominated postflop situations.

72o is too weak to continue out of position against the big blind, even with a cheap completion.
