Hold'em table

7-5 offsuit is a weak hand, and out of position against two players who still have to act after me, folding on the button is the disciplined play. Calling 100 to see a flop with a hand this poor has negative expected value.

Ace-king suited is a premium heads-up hand. Raising to 300 builds the pot and puts pressure on the big blind.

73o is too weak to defend against a raise from the small blind. Folding is clearly the best EV decision.

T8 suited is a playable button open three-handed, and raising gives me a chance to win the blinds or play a pot in position.

A3o plays poorly out of position against a button raise with the big blind still left to act, making folding standard.

Getting 400 into 150 (about 2.7-to-1) in the big blind against a button min-raise-sized open, so 4h6d offloads cheaply. Defending is reasonable with a wide button range, and I'll play carefully postflop.

Holding 4h6d on a Th5d Qh flop, I have only a gutshot and a backdoor heart draw. The out-of-position pot is small, so I check and keep the price low against the preflop raiser.

Middle pair can get value from draws and weaker pairs. A small bet also denies free cards while limiting the pot against a queen.

I have a gutshot straight draw (needs a 7 for 4-5-6-7-8... actually 3-4-5-6-7 shape with 4,5,6 needs 3 or 7) plus a backdoor heart flush draw. The price is 180 to win 730, about 3.0 to 1 odds, so calling is reasonable against a button c-bet with a wide range. .

I have 6-high with a gutshot-type draw only (4-6 with board T-5-Q-K gives no real straight draw), so I have no showdown value; checking is cheapest and avoids bloating the pot against a button that bet the flop.

My pair of tens has showdown value, but the king improves many hands that called the flop. Checking keeps the pot manageable.

I have 6-high with no pair and no made draw on a Th 5d Qh Kd 9c board, so showdown value is nil. Seat 2 checked the turn, but a bluff into a range that called the flop is unlikely to work well enough, so I check.

My pair of tens has some showdown value, but the coordinated board makes a value bet unlikely to be called by enough worse hands. Checking avoids risking more chips against a stronger hand.

J7o is too weak to open profitably from the button in 3-handed play.

7h8s is a decent suited-ish connector-type hand heads-up against the big blind; completing for 50 more gets a good price (3:1), so calling is better than folding, and raising is unnecessary.

With 5-3 offsuit against a small-blind limp, I can see the flop for free rather than build a pot with a weak hand.

Top pair (8s on 8d-2h-4h) with a backdoor/gutshot-ish draw in a heads-up pot; bet small for value and to charge flush draws. I'm first to act out of position against the big blind, who checked preflop with a capped range.

I have an open-ended straight draw and position. The small flop bet gives me a reasonable price to continue.

I have top pair (8s with 8d on board) on a 8d 2h 4h Qd board with a heart draw possible. Betting about 65% of the pot for value and protection against flush and straight draws seems right while heads-up in position-less spot as first to act.The opponent just called the flop, so a moderate bet extracts value from weaker pairs and draws.

The straight draw has eight likely outs, but the 300-chip turn bet gives insufficient direct odds. The extra river payoff needed to justify a call is uncertain.

7-9 offsuit is a weak hand out of position postflop against two opponents, so folding on the button avoids a marginal, low-equity spot.

7-2 offsuit is too weak to continue from the small blind against the big blind.

KQ suited is a strong button hand three-handed, so I open for value while keeping the sizing modest.

Getting attractive pot odds with no rake to set-mine against the button's wide opening range.

Q6 offsuit is weak, and I'd be out of position against a button raise and a small blind call. Calling 150 to win 600 gives decent odds, but I'd have poor equity and playability, so I fold.

Holding an underpair with no diamond on a very wet monotone flop, checking out of position is the standard defensive play.

On this coordinated monotone flop, K-high has a gutshot and overcards but no diamond. Checking in position lets me see a turn without risking a check-raise.

The board has four diamonds and we hold pocket threes with no diamond, so checking is the only sensible play out of position.

With no diamond on a four-diamond board and only a gutshot straight draw, I prefer to check and take a free river card.

I hold pocket threes with no diamond on a four-flush board; bluffing without blockers is too risky, so checking gives a free showdown.

King-high has little showdown value. A modest river bluff can fold out weak pairs and other hands without a diamond.

Holding a pair of threes with no diamond on a four-flush board, we only beat pure no-diamond bluffs, making this a clear fold to a river bet.

K8s is a strong suited king well within our standard opening range from the button 3-handed.

7-5 offsuit is weak, and I'd be out of position against a button raise with the big blind still to act behind me. Calling 200 more isn't worth it.

The button can open a wide range, and with no rake, J6 offsuit has enough equity to defend the big blind for 150 more chips.

I have jack-high with no pair or immediate straight draw. Checking avoids putting more chips into the pot with a weak hand.

I have King-high with backdoor flush and straight draws in position; checking back allows me to realize my equity and see a turn card for free.

I have an open-ended straight draw, and the preflop raiser checked the flop. A turn bet can win the pot now while leaving me outs if called.

I only have a gutshot straight draw with poor pot odds (needing 28% while possessing roughly 9% clean equity) and weak implied odds on an obvious four-to-a-straight river.
