Hold'em table

Two-jack offsuit is a weak holding, and facing 100 to call into a 150 pot against two blinds, the price is not good enough to continue.

A5o is strong enough to raise in a heads-up small-blind vs. big-blind pot after the button folds, and raising can take it down preflop or isolate the big blind.

A9 suited is strong against a typical small-blind opening range. I can three-bet for value and play the rest of the hand in position.

A5o is dominated by the big blind's 3-betting range, and calling 600 out of position with a weak ace leads to difficult postflop spots. Folding preserves chips.

QJo on the button is strong enough to raise for initiative and position. A 3x raise can fold out weaker blinds or isolate with position.

A4 suited is a good three-bet from the small blind against a button open: it has an ace blocker and plays better heads-up than in a multiway pot.

Holding 2-8 offsuit facing a 1200 raise with 1100 to call, I'm well short of the roughly 40% equity needed against a likely strong range, so folding is correct.

QJo is dominated by the small blind's 3-betting range, and calling 900 more out of position for the rest of the hand is not profitable enough. Folding preserves chips for better spots.

Six-deuce offsuit is too weak to open from the button at 100 big blinds, even with position.

K-8 offsuit is a marginal holding, so completing the small blind for 50 is a low-cost way to see a flop heads-up against the big blind rather than raising with a weak hand.

With 6d3h in the big blind and no call required, checking keeps the pot small and lets me see a flop with a weak hand.

I have an open-ended straight draw with 8-high on a 5-6-7 board, which is worth seeing a free card with, and checking keeps the pot small.

I have a pair of sixes plus a gutshot on a draw-heavy board, so betting protects my equity and can get value from worse pairs or draws.

I have an open-ended straight draw with King-high and no made hand, and the 150 call is roughly break-even against about 32% equity with the pot odds offered, so calling is reasonable over folding or raising.

I have only an open-ended straight draw with no made hand, so checking keeps the pot small and avoids facing a large raise from seat_2.

I have a marginal pair of sixes with a gutshot; checking controls the pot and avoids getting raised on a scary turn.

I have king-high with no made hand on a paired-free board, and seat_2 checked the turn, so checking keeps the pot small and avoids a bluff-raise I can't profitably call.

T7 offsuit on the button in a 3-handed pot is a marginal hand, but calling 100 to see a cheap flop is reasonable given the late position and the small price.

Q4s is weak but closing the preflop action for only 50 more into a 250 pot gives good odds, and raising into a limper and the big blind risks unnecessary chips.

J5 offsuit is too weak to raise against two limpers, and I can see the flop for free.

Semi-bluffing with a flush draw and queen-high; decent fold equity and equity when called. Betting also builds the pot for when a heart arrives.

With no pair and only weak backdoor draws on a two-heart flop, calling the bet with another player still to act is unlikely to be profitable.

Holding a pair of sevens with a T kicker against a single opponent, I have enough equity and pot odds of about 28% to call the 200 flop raise, and I can reassess on the turn.

We have a strong combo draw (flush draw plus gutshot straight draw) and can apply pressure as the flop aggressor. Betting the turn builds the pot and may fold out weaker pairs.

I hold two pair (tens and sevens) and the opponent has been betting aggressively, so raising for value against a likely wide range is reasonable. The minimum raise keeps the risk modest while building the pot.

I have a flush draw with Qh4h on a two-heart board and am getting nearly direct odds to call the min-raise; calling preserves stack and lets me see the river.

Q-high with a missed flush draw has no showdown value, and seat_1 has shown strength by raising the turn. I check and will fold to a bet.

Holding Tens and Sevens, a medium-strength two pair with no obvious straight or flush on this board, so checking keeps the pot controlled and lets me get to showdown.

Three-handed on the button with a suited connector; raising applies pressure, can take the blinds, and lets me play a pot in position.

K2 offsuit is too weak to call a button raise from the small blind with the big blind still to act.

Facing a 200-chip call into a 450-chip pot heads-up against a wide button range, 89 offsuit has enough equity and playability to continue.

Two pair (nines and eights) is strong on this board, so I bet about two-thirds pot for value while the button and small blind have shown little strength.

My 3d6d has no pair, no real draw, and only low cards on a coordinated board. Facing a 400 bet into 1050, folding is the disciplined choice.

Pocket eights are strong on the button in a three-handed game, so I open-raise for value and initiative.

Facing a 250 open from the button with 200 to call and 400 in the pot, J6 offsuit has enough playability in a three-way 100bb pot to justify a call over folding.

Getting 5:1 pot odds with a suited ace, calling to see a flop in position.

I have Jd 6s on a King-high board with no pair and no strong draw, so checking keeps the pot small and avoids bloating it out of position.

Check to control the pot with the nut flush draw on a paired board; there is no need to bloat it multiway before seeing the turn.

With pocket eights on a K-K-Q board against two opponents, a bet is unlikely to get called by many worse hands. Checking in position keeps the pot manageable.

I have J-6 with no pair on a K-Q-K-2 board, so checking keeps the pot small and avoids investing more chips without a made hand.

Semi-bluffing with the nut flush draw and an overcard; both opponents checked flop and turn, so betting can take the pot or build value if I hit.

My pocket eights can beat a turn stab or a heart draw, and the 500-chip bet offers sufficient pot odds to continue. Raising would risk too much against kings and queens.

I have J-6 with no pair against a turn raise on a K-Q-K-2 board, so I'm behind a likely king holding and have only a weak backdoor draw. Folding avoids putting 500 more chips in with little equity.

My hand is only ace-high with trips on board; checking avoids putting more chips in when many hands beat me, and I can fold to a bet.

My eights make a full house, but a queen, a higher pocket pair, or a king beats me. Checking takes the showdown without risking a bet that worse hands may not call.
