Hold'em table

3-7 offsuit is one of the worst starting hands and I'm out of position against two players for a full bet; folding is clearly best with no reads yet.

Button folded, so KQo is strong heads-up against the big blind. A raise to 300 builds the pot and takes the initiative rather than just completing.

In a BvB confrontation, JTo has sufficient equity and playability in position getting 2 to 1 pot odds to call a 3bb open.

I have two overcards and the preflop initiative on a paired flop, so a small c-bet applies pressure and can win the pot immediately.

I hold top pair with a decent kicker on a paired dry board, and facing a small 1/3 pot bet, calling is standard.

King-queen high has no pair or draw on a paired jack-five board, and the flop caller is unlikely to fold to another barrel. Checking keeps the pot small and preserves a free river.

I have top pair with a mediocre kicker on a paired board; checking back controls the pot and realizes equity in position.

I have trips with KQ kickers and showdown value, but many full houses and ace-high kickers beat me. With no bet to call, checking is better than betting into a calling range that is mostly stronger.

I hold a full house (Fives full of Jacks). Checking behind ensures I realize my showdown value against missed hands and underpairs without risking a check-raise from better hands or getting called only by superior full houses.

J7s is a playable button open in three-handed poker, so I raise to 2.5bb to take the initiative rather than flat the big blind.

A5o has poor playability out of position against a button open, making fold the standard play from the small blind.

Calling 150 into a 400 pot needs only ~27% equity, and 54o has roughly that against a wide 3-handed button open, so it's a marginally profitable flop peek despite being out of position.

I hold 5-high with no pair and no meaningful draw on an A-Q-J board, so betting or raising has little fold equity against a preflop raiser. Checking minimizes cost; I plan to fold to serious aggression.

Jack-seven is only third pair with a weak kicker on a queen-ace-jack board that favors the big blind's calling range, so I check back for pot control and to realize equity.

My 54 has essentially no showdown value, but the 9h strongly favors a BB calling range while seat_2's flop check-back is often weak floats or small pairs, so a ~2/3-pot stab needs only ~40% folds to profit. I fold immediately to a check-raise.

I have third pair plus a diamond flush draw, so my equity is enough to continue against a 400 bet into 550. Calling realizes the draw and keeps the pot manageable rather than inflating it with a weak pair.

The river four gives me only a weak pair of fours, which loses to nearly every Ax/Qx/Jx/9x hand that would call a turn bet; a bluff folds out little, so checking and folding to aggression is the EV-maximizing line.

Pair of jacks has some showdown value against busted draws and small pairs, but worse hands fold and better aces or queens call a river bet. Checking back is the higher-EV line.

Open-raising with pocket eights on the button for value and initiative in a 3-handed game.

Ten-six offsuit is far too weak to defend the small blind against a 2.5x button raise; calling 200 more with a hand that rarely connects is -EV.

32 offsuit is too weak to continue against a button open, even with a cheap call, so I fold rather than play a dominated hand out of position.

Suited connector on the button 3-handed is a standard open; raising to 2.5x builds the pot with fold equity and positional initiative postflop.

A2o is too weak to continue from the small blind against a button open, especially out of position. Folding avoids a dominated ace and a poor postflop spot.

Q7o plays poorly out of position against a 2.5x button open and does not realize enough equity to defend profitably.

76o is a standard wide button open in three-handed play; raising takes the initiative rather than calling out of position with a weak offsuit hand.

Folding 3d 4c from the small blind facing a button raise, as this hand is too weak to continue out of position.

95o is dominated by the button's raising range and plays poorly out of position; calling 150 more has negative expected value, so folding is the best line.

T2o is too weak to open even on the button in 3-handed play. Folding is clearly the highest EV move.

Q4o is playable heads-up; calling 50 into a 150 pot with roughly 54% equity versus a random hand is profitable, and keeping the pot small with a weak kicker avoids tough spots against the big blind.

Pocket sevens are ahead of a heads-up limp, so I raise to build the pot and deny a free flop rather than check.

Q4 offsuit is far too weak to call a 4x raise from the big blind after limping; I'm dominated by most of their raising range and out of position, so folding saves 300 chips.
