Hold'em table

J9 offsuit is a reasonable button open three-handed. Raising to 2.5 big blinds pressures the blinds while letting us play in position if called.

J6 suited is too weak to call a button raise out of position from the small blind with the big blind still to act; realization will be poor despite suitedness.

KTs is a strong hand in a 3-handed game; 3-betting from the big blind puts pressure on the button's wide opening range and builds a pot with a hand that flops well.

J9 offsuit is a weak defend against a big-blind three-bet, with substantial domination risk and limited playability. Position and the small sizing do not justify continuing without evidence of an unusually wide three-betting range.

On the button in 3-handed play, K6o is strong enough to open and pressure the blinds rather than fold or limp. A 2.5bb raise gives fold equity while keeping the pot manageable if called.

Q4s is a marginal hand from the small blind and playing out of position against a button raise is unfavorable; folding preserves chips for better spots.

Calling costs 150 to contest a 550-chip pot, giving favorable odds against a button opening range. A4 suited has enough equity and nut-flush potential to defend without inflating the pot out of position.

Top pair with an ace kicker, a gutshot, and backdoor clubs has solid showdown value and room to improve. Checking keeps the button’s weaker hands and bluffs in while preserving the option to continue against a bet.

In position with a gutshot to the straight and a king overcard, a semi-bluff c-bet can take the pot now and still has good equity if called.

Top pair with an ace kicker, a gutshot, and a backdoor nut-flush draw comfortably supports calling this bet. Calling keeps the button’s bluffs in and avoids inflating the pot against overpairs and stronger hands.

My pair of fours has showdown value and a gutshot, but the queen favors the button’s range. Checking keeps the pot controlled and lets me assess their sizing rather than lead into stronger hands.

With a spade flush draw plus a gutshot to the straight on the turn, betting after the check applies fold pressure while building the pot for my many outs.

I have a pair plus a wheel gutshot, with additional improvement possibilities against one-pair value hands. At roughly 27.5% required equity, calling is reasonable against a button range that can also barrel unpaired hands and new spade draws.

My pair of fours retains some showdown value against missed draws and unpaired bluffs, but a value bet is unlikely to get called by worse. Checking avoids turning that showdown value into a bluff on a four-to-a-straight board.

With only a pair of sixes after opponent check-called flop and turn, a river bet is called by queens, straights and better pairs while worse missed draws fold and already lose at showdown, so checking realizes equity.

A4o is a marginal but playable hand from the button, especially 3-handed. Raising aims to steal the blinds or take control with position, while folding is too tight and calling invites multiway action without initiative.

73 offsuit is too weak to defend against a button raise from the small blind, with poor equity realization and the big blind still to act.

J8 suited is strong enough to defend the big blind heads-up against a wide button 2.5x open, getting good pot odds for only 1.5bb more.

Out of position with only jack-high on a paired queen board and weak backdoors; checking preserves equity and avoids building a pot against the preflop raiser.

I have Ace-high with no draw on a paired board; checking behind to see a free turn card and avoid building a pot with a weak hand.

Semi-bluff with the club flush draw on a paired board; opponent checked back the flop showing weakness, so betting can win by fold equity while still having outs if called.

I have the nut flush draw and an overcard, and calling gives me good implied odds to hit on the river while keeping the pot manageable.

I missed my club and gutshot draws and only have a pair of queens with a jack kicker. Checking keeps the pot controlled and gives free showdown against missed heart draws and weaker kickers, while a bluff is likely called by better queen kickers, two pair, or trips.

We have Ace-high with no showdown value. Seat 2 checked the river after betting the turn, often indicating a medium-strength hand that might fold to pressure. A bluff raise of about 2/3 pot risks 900 to win 1350, needing folds around 40% of the time, which seems plausible given their line.

I only have board pair of queens with a jack kicker and a missed club draw. Opponent's check-back, turn call, and river bet is consistent with trips or better, and even ace/king-high bluffs outkick me, so calling 900 is unprofitable.

A3 offsuit is a reasonable button open three-handed, with an ace blocker and positional advantage. Raising to 2.5 big blinds pressures the blinds without investing too much with a weak kicker.

K6 offsuit is too weak to continue out of position from the small blind against a button raise with the big blind still to act.

62s is too weak to defend out of position against a button raise, especially with no additional equity from antes.

On the button in 3-handed play Q7o is a borderline wide open with position; raising applies pressure to the blinds and gives fold equity plus positional advantage if called.

K2s is too weak to play from the small blind facing a button raise, especially out of position with the big blind still to act.

Calling costs 150 to contest a final pot of 550, making 9-7 offsuit a reasonable big-blind defense against a button open with no rake. Its straight potential supports calling, while its weak blockers make a bluff three-bet less attractive.

With an open-ended straight draw and a backdoor heart draw, checking preserves options against the preflop raiser. This king-high board generally favors their range, so leading is less attractive.

As preflop raiser heads-up, a small continuation bet can fold out many hands that missed this K-high board. I have only queen-high, so taking the pot now is better than checking and likely losing at showdown.

I have an open-ended straight draw and a backdoor heart draw against a modest continuation bet. Calling preserves my implied odds without inflating the pot out of position with nine-high.

I turned the nut straight. Checking lets the aggressor continue betting and sets up a value check-raise on this draw-heavy board.

With Q-high and only a gutshot to the 9, betting into a flop caller on a king-high board risks calls from Kx and flush draws; checking in position takes a free river cheaply.

Nine-high has almost no showdown value, and the turn check leaves the opponent with many missed draws and marginal hands. A two-thirds-pot bluff can credibly represent a king or better and needs folds only 40% of the time to break even.

Queen-high with no pair has little showdown value against a flop call and 2/3-pot river lead; most of villain's calling range is pairs or ace-high draws that beat us, so calling 700 is not profitable.

4s Tc is a very weak hand, especially from first position preflop. Folding avoids losing chips with a hand that has poor equity and playability.

Q8 suited is a good blind-versus-blind opening hand. Raising to 3bb pressures the big blind while retaining reasonable postflop playability when called.

Heads-up in position as big blind, K4o has enough equity against a wide small-blind steal to defend for 200 into 400, needing only about 33%.

A one-third-pot continuation bet leverages my preflop range advantage on this paired board and can fold out unpaired hands, including some better queen-high and king-high holdings. The small sizing keeps this low-equity bluff inexpensive.

In position facing a small one-third pot bet on a paired flop, King-high has enough showdown value against a wide small-blind opening and frequent continuation-bet range to justify calling at 25% pot odds.

With queen-high and no diamond, I have little equity and no useful flush blocker for a turn bluff. Checking avoids investing further against a flop-calling range strengthened by the third diamond.

Opponent checked the flush-completing turn after a small flop bet, showing weakness. I have only king-high, so betting to represent the diamond flush gives better fold equity than checking to showdown.

Queen-high with no diamond and no meaningful draw is too weak to continue against this turn bet. We lack both sufficient equity to call and useful blockers for a bluff-raise.
