Hold'em table

K4 offsuit is too weak to open profitably on the button in this configuration.

J8 suited is strong enough to raise heads-up from the small blind, giving me initiative against the big blind.

K8s in the BB facing a 3x SB open is getting 2:1 with position, which is a clear defend; calling realizes equity well without bloating the pot out of position for the opener.

A small continuation bet on this dry ace-high flop leverages my preflop range advantage without risking much with jack-high.

Against a small 1/3-pot c-bet we are getting 4:1, and K8s has a backdoor flush draw and some overcard equity, so it is a reasonable defend on this A-high board.

J-high has little showdown value, but this turn gives me no meaningful draw or strong blockers to support another bluff. I'll check and avoid investing more against the flop caller.

K8 has showdown value but gets little value from worse hands and gets raised or called by better ones, so I'll check back to control the pot and bluff-catch the river.

J-high has little showdown value. A 700-chip river bluff can pressure the opponent's weak pairs and missed draws after the turn checked through.

Second pair is a reasonable bluff-catcher: villain checked the turn, and the river bet is small at 41% of the pot, so I only need about 29% equity. Villain's range also includes missed draws and weaker holdings, so calling is profitable.

8-6 offsuit is a marginal button open against two players with full stacks. I’ll pass on this spot.

A2 suited is a strong hand in a blind-vs-blind spot, well ahead of the big blind's range. A 3x raise builds the pot and applies pressure.

K4 offsuit is too weak to defend against a small-blind raise, especially out of position.

J7o on the button 3-handed is a standard open; steal the blinds with a 2.5x raise.

A5 offsuit is too weak to defend from the small blind against a button open with the big blind still behind.

J9 offsuit is strong enough to defend the big blind against a button raise to 2.5 big blinds. Calling keeps the pot manageable out of position.

I have no pair or immediate draw on this flop. Checking avoids building the pot out of position.

Second pair with a backdoor straight draw on a wet board versus a BB check; a small bet gets value from worse pairs and draws and denies equity to overcards, while staying cheap if we're behind.

The small flop bet gives me a good price to continue against a wide button range. I can improve with a jack or nine and have backdoor straight and flush possibilities.

I have only a gutshot straight draw and no made hand. Checking avoids investing more out of position without a stronger draw.

Bottom pair has some showdown value but gets called only by better hands and the turn king improves many of the flop-calling hands, so check back and take a free river.

With third pair and no strong reason to expect a worse hand to call, I prefer to check and take my showdown value.

Two pair (jacks and sevens) beats most of a passive BB range that check-called the flop, including Qx, Kx and 7x. A small value bet gets called by worse while limiting losses to flushes and straights.

The river bet is small relative to the pot, so my pair of jacks needs to beat only a modest portion of the bettor’s range. Missed heart draws and other bluffs make a call worthwhile.

J2 offsuit is too weak to profitably open from the button in this stack-reset format.

A9 offsuit is strong enough to raise heads-up against the big blind. Raising to 300 builds value while keeping the pot manageable out of position.

Getting 2:1 in position against a wide small-blind steal range, so 74o is a reasonable defend. Calling keeps the pot small and lets me realize equity postflop.

A small continuation bet can fold out some unpaired hands while keeping the risk modest. Ace-high also has some chance to improve if called.

Middle pair in position getting 4:1 against a small c-bet is a clear call; raising would fold out worse hands and get called by better ones.

My nine improved to second pair, but a jack remains likely in the caller’s range. Checking keeps the pot manageable while allowing weaker hands or draws to bet.

Third pair has showdown value but can't comfortably bet for value or protection against the preflop raiser. Checking back keeps the pot small and gives a free river.

Second pair with an ace kicker can get thin value from weaker nines and other pairs. A small river bet limits the cost when called by a jack.

Getting better than 4:1 on a small river bet. The busted diamond draw is a plausible bluff, so a pair of sevens has enough showdown value to call.

T8 offsuit is playable as a button open three-handed. A 2.5-big-blind raise gives me a chance to win the blinds while keeping the pot manageable.

K4o from the small blind facing a button open, with the big blind still behind, is a weak, dominated hand that would be out of position. Folding is standard.

8d2d is a very weak offsuit-equivalent low hand despite suitedness, and calling or defending aggressively against the button raise is unprofitable.

J4 offsuit is too weak to open from the button in 3-handed play against two blinds with 100bb stacks, so folding is the lowest-risk choice.

QJs is a strong heads-up blind-versus-blind holding and benefits from building the pot while retaining playability.

K7 offsuit is strong enough to defend the big blind against a small-blind open. Calling keeps the pot manageable and gives me position after the flop.

I have top pair with a strong jack kicker and a diamond blocker. A modest continuation bet extracts value from worse queens, pairs, and draws while keeping the pot manageable.

The small flop bet gives me a reasonable price to continue in position with a king overcard and backdoor straight and flush possibilities.

The king is a poor card to barrel into after a flop call, while checking preserves our showdown value with queens and keeps our draw equity.

Top pair is likely ahead of many queens and draws that called the flop. Betting for value also charges those draws before the river.

I have a queen with a jack-high diamond draw and a gutshot, giving enough equity and showdown value to continue for the turn bet.

Our two pair is beaten by any king or ten, both plausible after the turn barrel. Checking preserves value against missed draws and weaker queens while avoiding thin value betting into a stronger range.

Top pair has showdown value, but the river completes several straights and improves many hands that would call a bet. Checking avoids a costly raise while collecting the pot when my pair is best.
