Hold'em table

Button open with 78o is a standard steal; a 2.5bb raise applies pressure on the blinds and realizes equity better than limping or folding.

Ten-five offsuit is far too weak to continue against a 2.5x button raise, even with the small blind discount. Calling 200 more into a 400 pot with dominated, disconnected cards is -EV; folding is standard.

Getting attractive pot odds of 2.67:1 closing the preflop action, calling with a pocket pair to set-mine is profitable.

Check out of position with a weak underpair on an ace-high board.

I have no pair, draw, or meaningful equity on A-T-4, so I check back rather than bluff into the preflop caller.

Holding pocket threes on an Ace-King-Ten heavy board gives us minimal showdown value, but checking is free and allows us to see the river.

I have 78o with no pair and no draw on A-K-T-4, so there is no value in betting. Checking keeps the pot small and realizes the free card.

I am playing the board with pocket threes. Checking allows me to see a showdown for free or easily fold to a river bet.

I have complete air on a board with an ace and king, and the pot was checked down. Checking behind avoids turning a small pot into a bluff that any pair can call.

JTo offsuit is a standard button open three-handed; raising to 3bb isolates the blinds and leverages my position, with an easy fold if either blind three-bets.

96 offsuit is too weak to call or 3-bet from the small blind against a button open.

K5 offsuit is too weak to continue against a button open after the small blind folds. Folding avoids paying 200 more with a dominated, low-equity hand.

65 offsuit is too weak to open from the button, even in 3-handed play.

Button folded, so this is blind versus blind with A7o. A raise to 300 takes the initiative and applies pressure before playing out of position.

K2o is far too weak to call a 3x raise even with position; I'm dominated by every king-x hand and the hand flops poorly, so folding and saving 200 chips is clearly best.

Q8s is a playable suited hand on the button, so I open to 2.5bb to take the initiative and fold out weaker hands.

J9s is a weak one-gap suited hand to defend out of position from the small blind against a button raise, with the big blind still to act and squeeze risk. Folding avoids dominated, hard-to-play postflop spots for a small investment.

T2o is an unplayable hand out of position facing a button open.

On the button with both blinds already committed, a small raise to 250 attacks the dead money with good fold equity, and Q7o plays fine with position if called.

Q7o is too weak to defend out of position against a button raise with the big blind still to act.

5-9 offsuit is too weak to continue out of position against a button open; folding avoids paying 150 more with poor equity and playability.

K5s is a profitable open from the button in 3-handed play with position.

Q8s is too weak to continue out of position against a button raise with the big blind still to act. Folding avoids a dominated, low-equity spot.

Calling 150 into a 400 pot needs only ~27% equity, and A3s has ~45% raw equity against a wide button opening range, with flush and top-pair potential. The price is too good to fold despite being out of position with a weak kicker.

I flopped bottom pair (threes) with an ace kicker against the preflop button raiser. Checking keeps the pot small and lets me evaluate his aggression rather than donk-betting a weak marginal hand.

Flopped top pair on a dry board in position; placing a small continuation bet of roughly one-third pot for thin value and protection.

Facing a small ~35% pot c-bet, I only need ~19% equity and my bottom pair plus backdoor draws likely has ~30% against a button c-betting range that includes bluffs. Calling is cheap; I can fold to further aggression on the turn.

The turn 9d gave me two pair (nines and threes), but seat_3's flop-betting range is full of Kx, 9x, and 33 that dominate me, so I'll check and keep the pot controlled rather than bloat it out of position. I'm too strong to fold a reasonable bet but too vulnerable to raise for value.

I have top pair with a weak kicker on a paired board; checking back keeps the pot manageable and controls showdown value in position.

I have top two pair with a weak kicker on a paired board; checking back preserves showdown value against missed draws and avoids value-owning myself against better Kings or trip Nines.
