Hold'em table

Q8 suited is playable from the button in a 3-handed game, and a standard 3x open builds the pot with position. Raising also gives me fold equity against the blinds.

65 offsuit is too weak to defend from the small blind against a 3x open.

A4 offsuit is strong enough to defend the big blind heads-up, and calling keeps weaker hands in without inflating the pot.

With ace-high on a paired board, checking keeps the pot manageable and lets the preflop raiser act. I can reassess based on their response and later cards.

Seat_3 checked to me after flat-calling preflop, which often signals weakness; a half-pot continuation bet on this dry paired board can take the pot down now, and I have backdoor equity if called.

The small flop bet can be a routine continuation bet, and ace-high with a backdoor heart draw has enough equity to continue at these pot odds. Raising would risk too much with a weak hand.}

I have only ace-high on a paired board, and the button’s flop bet-call range can contain plenty of made hands. I’ll check and avoid building the pot without a meaningful improvement.

I have a flush draw plus gutshot to the 6, so a half-pot turn semi-bluff builds the pot when I hit and can fold out weak K-x or pairs now. Checking keeps pot control but gives a free card with little fold equity gained.

A-high has meaningful showdown value against a button double-barrel range that can contain missed overcards, and the pot odds require only about 24% equity. Raising would mostly fold out bluffs and get action from better hands.

The river ace improves me to aces and sevens, and a small value bet can get called by Kx after the flop and turn barrels. I’ll keep it modest because better Ax can beat me.

I hold only Q-high (no pair, no made flush with just four diamonds on board), so I lose to every pair. Seat_3 called two streets then led the river, a line that's almost always value; calling or bluff-raising is -EV.

J8o is on the weaker fringe of 3-handed button opening ranges, especially with no ante. Folding is clean and avoids playing a marginal offsuit hand postflop.

With the button folded, A3 offsuit is a reasonable heads-up value raise from the small blind; raising to 300 puts pressure on the big blind and takes initiative.

Eight-three offsuit is far too weak to call a 3x raise out of position; folding preserves chips for better spots.

Q7 offsuit is a reasonable button open in a three-handed game. I raise to 2.5 big blinds to apply pressure while keeping the size controlled.

Ten-eight offsuit is too weak to defend out of position against a 2.5x button raise; folding avoids playing a dominated, hard-to-play hand for 200 chips.

T7o is too weak to defend out of position against a button open.

Pocket deuces on the button in a 3-handed game play well as a small open-raise to build the pot and take initiative; I can fold to heavy resistance or set-mine cheaply if called.

J9 offsuit plays poorly out of position against a button raise with the big blind left to act, making folding standard.

AQ offsuit is strong against a button open in a three-handed game. I’ll 3-bet for value and take initiative while charging weaker hands to continue.

Pocket twos have poor equity against a 3-bet range and weak implied odds for set mining at 100bb depth. Folding the 600 call is the disciplined play.

Ten-six offsuit is too weak to open profitably from the button even three-handed.

With the button folded, K♦2♦ is a playable heads-up hand. I raise to 3 big blinds to take initiative while keeping the sizing moderate.

4-3 offsuit is too weak to open from the button against both blinds, and calling would invite a difficult, low-equity pot.

K8s in the SB heads-up is well ahead of BB's calling range; a standard 2.5x raise builds the pot with fold equity while keeping the hand playable postflop.

Calling the small blind's 2.5bb open in position with an Ace, getting favorable pot odds of 150 to win 350.

I missed the flop with K8s and have no draw; checking keeps the pot small heads-up and lets me see a free turn or fold to aggression cheaply.

I have bottom pair with an ace kicker in position; checking behind keeps the pot manageable and allows me to see a turn card cheaply.

I have second pair (eights) with a king kicker heads-up after a checked flop; a small turn bet builds the pot while charging draws and worse pairs.

Holding fourth pair on a wet board facing a turn bet after the flop checked through offers insufficient equity and poor reverse implied odds.
