Hold'em table

A3 offsuit is a reasonable button open in a three-handed game; raising applies pressure while retaining positional advantage postflop.

A9 offsuit has an ace blocker and is strong enough to three-bet against a likely wide button opening range. Raising also avoids playing a multiway pot out of position.

65o facing an open and a 3-bet from the small blind, with the opener still left to act, is a clear fold with poor pot odds.

A3 offsuit is too weak to continue against the small blind’s large 3-bet; calling risks playing a bloated pot dominated by stronger aces.

T3 offsuit is too weak to open from the button at 100 big blinds.

A7s is a strong hand blind-vs-blind after the button folds, so raising for value and fold equity is standard. A 3x raise sets up a good pot while out of position.

8♠4♠ is too weak to defend against a 3x raise, especially out of position. Folding avoids investing more with a hand that will often be dominated or miss the flop.

Pocket queens on the button are a premium hand, so I open to 2.5bb for value and to build the pot.

4♠2♠ is a weak, low-playability hand from the small blind, and calling leaves me out of position with the big blind still to act. Fold rather than pay the raise.

8-4 offsuit plays poorly out of position against a button raise, and calling another 150 chips is unlikely to be profitable.

On the button three-handed, 9♠5♣ is playable as an open raise; a small sizing applies pressure to the blinds while limiting risk with a marginal hand.

T6 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act.

Getting 150 to win 400 in the big blind against a wide button open, and 100bb deep gives good implied odds to set-mine with pocket threes.

Small pair on an A-Q-8 board that favors the button's raising range; I'll check and give up to meaningful aggression, since there's little value in betting.

A small continuation bet leverages my preflop range advantage on this ace-high board. My hand is weak but has backdoor straight and flush possibilities if called.

Getting about 4:1 on a small c-bet, 33 has enough equity (set outs plus showdown value against the button's wide range-bet) to continue. Raising would only fold out worse hands.

A pair of 33 on the A-8-Q-J board with a flush draw out has almost no showdown value and very little equity. Checking lets me realize whatever it has and fold to a bet.

I have only a gutshot draw and no pair, so checking behind avoids inflating the pot with a weak hand while preserving the chance to improve on the river.

A pair of threes on a four-to-straight, paired river board is pure showdown value, and the opponent checked back the turn, so it may still be good. Betting would only get called by better hands, so checking is best.

With only nine-high and no showdown value, I’m making a modest river bluff after the turn checked through. The paired board and third diamond give me a credible value story and may fold out weaker pairs or missed draws.

On this board our pocket threes only play the board's pair of eights and lose to any ace, queen, jack, eight, higher pocket pair, straight or flush. The small river bet after the turn check-back comes mostly from made hands, so we have less than the roughly 23% equity needed to call.

On the button in a three-handed pot, 9-6 offsuit is a marginal but playable steal with position. A modest raise can win the blinds or let me play postflop in position.

63o from the small blind facing a button open, with the big blind still to act, is a clear fold. It plays poorly out of position.

Calling the small additional amount from the big blind gets a favorable price against a button open; folding would be too tight, while 7-5 offsuit is not strong enough to reraise.

I have no pair or meaningful draw on a coordinated flop, so checking avoids putting more chips in without a strong reason.

I have a straight draw, but this connected flop hits the big blind's calling range often. Checking back takes a free card while keeping the pot manageable.

I have only 7-high with no meaningful draw, so betting offers little value and risks being called or raised. I’ll take the free river card.

I have an open-ended straight draw but little showdown value. Betting after the big blind checks again can win the pot now while leaving a chance to improve if called.

I have no pair or meaningful draw on a paired, connected board, so calling the turn bet has poor odds.

Pocket sixes on the button in a 3-handed game are a clear open-raise; 2.5bb is a standard size.

9♥2♦ is a very weak offsuit hand from the small blind, and calling the raise would invite the big blind to continue as well.

J5 offsuit is a marginal defense against a button raise, and its poor playability out of position makes folding preferable.
