Hold'em table

K4o is a playable king-high on the button in 3-handed play; raising applies pressure to the blinds and leverages position.

A-T offsuit plays well 3-handed against a button open; raising isolates, denies the big blind cheap odds, and can take the pot preflop.

Pocket nines do well against a small blind that 3-bets wide against a button open in a 3-handed game. If the button folds, I'll be in position against the small blind postflop, so calling is better than folding or 4-betting into a range that could push me off the hand.

K4o is weak and dominated facing a 3-bet to 900 and a big blind cold call; folding avoids playing a marginal hand for 650 more.

With Ace-high and no draw on a low, dry flop, checking is standard to keep the pot small and evaluate my opponent's action.

99 is likely ahead of the SB's checked unpaired broadway 3-bet hands on this low board. A small bet gets value and denies them cheap overcard equity, while keeping the pot manageable against overpairs.

With AdTs on a 5s2h6d board, I have no pair, no flush draw, and only weak backdoor straight potential. The 700 bet gives good pot odds, but I am out of position and have little chance to improve. Folding preserves my stack of 9100 and avoids a marginal situation.

Q6o is too weak to play from the button against two opponents; folding avoids committing chips with a hand that is often dominated.

T7 suited plays well blind vs blind, so I'm raising to 3x from the small blind. This takes initiative rather than limping.

Q8o has enough equity against a wide small-blind steal getting 2-to-1, and I will be in position postflop, so defending the big blind is preferable to folding.

The Q-J-2 board favors my preflop raising range, and my T7 has a backdoor straight draw, so a small one-third-pot c-bet works as a cheap bluff. It also lets me keep betting on good turns.

Top pair on Q-J-2 with a flush draw present is well ahead of a small 1/3-pot c-bet range and has good pot odds; calling controls the pot with a weak kicker while keeping draws and weaker pairs in.

T7 has no pair and no real draw on this turn, and the BB's flop call range is strong and draw-heavy, so barreling has little fold equity. I'll check and give up unless something changes.

Top pair with a weak kicker on a double-flush-draw board; after opponent's turn check, betting protects against draws and gets value from Jacks and weaker pairs.

Ten-high with no pair and no real draw on J-Q board facing a turn bet; folding is clearly best.

J9 suited on the button in 3-handed play is a clear opening hand, so I'm raising to 2.5bb to steal the blinds while keeping position.

As the small blind with a player behind, calling leaves me sandwiched out of position, so I prefer a 3-bet or fold strategy. Ace-six with an ace blocker is a good bluff candidate against a wide button open.

96o is extremely weak against a 3-bet; calling 700 more out of position with a trash hand is unprofitable.

Getting about 2.1:1 in position with 100bb stacks, J9s plays well enough postflop to call the small blind's 3-bet. It is too weak to 4-bet.

Top pair as the preflop 3-bettor; a small flop bet gets value from Qx and club draws and protects against overcards while keeping the pot manageable with a weak kicker.

J9 with no diamonds on board has no pair and no real draw on A-Q-4, facing a c-bet from a preflop 3-bettor whose range smashes this flop. A call can't continue profitably, so I fold.

J3 suited is below a profitable button opening range three-handed, with poor straight potential and a weak kicker that plays badly when called.

With J8s in the small blind and the button having folded, calling the additional 50 offers excellent pot odds and keeps the pot small while seeing a flop with a speculative hand. Raising would risk playing a larger pot out of position without a strong holding.

T5o is a weak hand against a small-blind limp, and checking gives a free flop in position. Raising with it doesn't gain much.

We have a flush draw with backdoor straight potential on a relatively dry board; a small bet can fold out weak hands from the big blind and build value when we hit.

T-high with only backdoor straight draws and no pair. Calling 100 into a 300 pot needs roughly 25% equity, which this hand doesn't have against a lead on an ace-high board.

On the button with T8o, it's a decent steal opportunity in a 3-handed game. Raising to 2.5bb puts pressure on the blinds without overcommitting.

95o in the small blind facing a button open with the big blind still to act is a clear fold. Calling out of position with a weak offsuit hand loses money.

2-7 offsuit is the weakest starting hand and facing a button raise to 250 from the big blind, calling 150 more has negative expected value.

KTo is a clear open from the button in 3-handed play. A standard 2.5bb raise takes the initiative and puts pressure on both blinds.

9s4s is too weak to call a button raise out of position with the big blind still to act; folding preserves stack versus poor postflop playability.

8c3o is a very weak hand from the big blind facing a button raise with no small blind to provide extra odds; calling or raising would be unprofitable long-term.
