Hold'em table

4h5h is a suited connector on the button in a 3-handed game, so it has good playability. Calling 100 to win a pot of 250 is a fair price, and I would rather keep the pot small than raise.

K2o has terrible playability out of position multiway; folding the small blind to the limp is standard.

J8 suited is strong enough to raise against a button limp, especially with the small blind's dead money in the pot.

45s suited on the button, getting 600+350 pot odds of about 2.7 to 1 with position against a big blind 3-bet-sized raise; calling is profitable and keeps the hand playable postflop.

J-high has little connection to this paired flop and no backdoor flush draw. Checking avoids building a pot with a weak hand.

Heads-up on a 9-9-3 board after the big blind checked. I hold 4h5h with a backdoor flush draw and two overcards to the 3 only, so I have little showdown value. A small bet of about a third of the pot can win the pot immediately against a range that missed the flop, and I have some equity if called.

The small bet gives me a good price against a wide range of hands that may bet after my check. I can reassess on the turn.

J-high has little chance to improve on this turn, and betting into the flop bettor would risk more chips without a strong draw. Checking keeps the pot small.

I have a pair of fives plus a gutshot draw on a 9-9-3-5 board. Seat 3 checked twice, which shows weakness, so a bet of about 40% of the pot should take the pot often and still leaves me some equity if called.

J-high has little showdown value and no meaningful draw on this turn. Calling 600 against a second bet is unlikely to be profitable.

A9s is well ahead of random hands and a standard open from the button in 3-handed play.

T2 offsuit plays poorly out of position against a button raise, with the big blind still to act.

J9o in the big blind is getting 400 to 150, about 2.7-to-1 pot odds, against a wide button open. I will defend by calling, since it is not strong enough to raise and has enough equity to see a flop.

Middle pair (jacks) on a Jc 7d Qh flop with a gutshot to the straight (T for K-T... actually 9-T needs T and K/8), heads-up out of position. Betting about 64% of the pot for value and protection against overcards and draws seems best.

We completely missed the flop with Ac9c on Jh-Qc-7d, and facing a sizable donk bet into a multiway-turned-heads-up pot, folding is standard.

J9 offsuit is a profitable button open three-handed, and a 2.5-big-blind raise uses positional advantage without risking too much.

Q5 offsuit is a weak hand out of position in the small blind, facing a button raise to 250 with the big blind still to act behind me. Folding is the disciplined choice.

Holding 64 offsuit out of position against a button raise is an easy fold with negative expected value.

K8o on the button in a 3-handed game is a reasonable open. A small raise takes advantage of position against two players who have not yet acted.

Folding 42s from the small blind against a button open, as it lacks sufficient playability and equity out of position.

Pocket threes can profitably defend the big blind against a 2.5bb button open, with enough stack depth to pursue set value.

With an underpair on a dry flop, I prefer to check and avoid building a pot out of position.

Heads-up on a Q-9-4 rainbow flop, I hold king-high with a backdoor straight draw, and the big blind checked. A small bet of about half the pot can fold out weaker hands and takes the pot often, and I can give up on later streets if I'm raised.

Pocket threes are an underpair on this Q-9-4 flop, with little chance to improve against a bet. Folding avoids committing more chips out of position.

Opening K7s on the button in 3-handed play is standard for value and position.

A8 suited is strong enough to three-bet against a button open. Raising to 1,000 applies pressure and avoids playing a multiway pot out of position.

QJo facing a button open and a small blind 3-bet to 1000 needs to call 900 more with a likely cold-call or squeeze situation out of position; it is dominated often and not profitable, so fold.

K7s is an easy fold against a 4x 3-bet out of the small blind.

A7 offsuit is strong enough to open on the button three-handed. A 2.5 big blind raise can win the blinds while keeping weaker hands in.

Pocket fours have good set-mining value at 200 to call into a 400 pot. A 3-bet out of the small blind with the big blind still to act isn't attractive, so I'll call.

Getting 4 to 1 pot odds closing the action preflop with suited ace A6d is an easy call.

Pocket fours on a J-3-K board with two clubs is a weak showdown-value hand against two opponents, and the preflop raiser on the button is likely to bet. Checking keeps the pot small and lets me see what they do.

I hold Ace-high with no real draw on a King-Jack high flop, so checking to the preflop aggressor is standard.

With ace-high and no immediate draw on a K-J-3 flop, betting into two opponents is unlikely to get enough folds. Checking keeps the pot small and lets me use position on the turn.

Pocket fours are a weak showdown hand on a J-3-K-9 board with two clubs, against two opponents who both checked the flop. Checking keeps the pot small and lets me see the river cheaply. A bet would rarely get called by worse hands.

I have Ace-high with virtually no equity on a coordinated board, so checking multiway is the most prudent play.

Ace-high has some showdown value, but this connected turn gives me little equity when called by either opponent. I'll check and take the free river.

My pair of fours is a weak showdown hand on a K-J-9-7-3 board, and everyone checked the flop and turn. Betting would mostly get called by better hands, so I check and take the free showdown.

In a three-way pot checked down on flop and turn, Ace-high has decent showdown value and bluffing multiway into the original raiser is low EV.

Bottom pair has some showdown value, but a river bet into two opponents is unlikely to get called often by worse hands.
