Hold'em table

92 offsuit is too weak to open from the button in a 3-handed game, even with position. Folding costs nothing.

T5o is a weak offsuit hand with the button already folded; not worth contesting against the BB with no equity edge.

Q9 suited on the button is a solid raising hand; isolating the blinds with a standard open-raise.

4c6h offsuit is too weak to defend from the small blind against a button raise with the big blind still behind.

Getting 150 to win 400 (about 27% equity needed) in the big blind against a wide button 2.5x open; 94o is a borderline defend, and the SB has folded, so the pot is heads-up. Calling is better than folding here.

I have 9-high with only a gutshot to the K-J (needs a J) on a board that hits the preflop raiser's range well. Checking to the button is standard.

I have top pair with a decent kicker on a dry-ish board; betting for value against a checking opponent.

9-high with no draw on a Q-T-5 two-tone board, facing a bet of about two-thirds pot. The price needs roughly 28% equity and this hand is far below that, so it is a clear fold.

7-4 offsuit is a weak button opening hand; folding preserves chips rather than entering a likely dominated multiway pot.

A7o is a clear raise in a blind-vs-blind spot after the button folds; raising to 3x applies pressure and gives us the initiative.

98s on the button in 3-handed play is a clear open; a 2.5bb raise applies pressure on the blinds and keeps position.

Q2 offsuit is too weak to defend against a button raise, especially out of position.

7-4 offsuit on the button facing a raise-call scenario isn't strong enough to invest in; folding preserves chips for better spots.

Pocket threes are well ahead of the blind's random range heads-up and benefit from taking initiative. Raising builds value while retaining manageable postflop decisions.

KQs is well ahead of a wide small-blind opening range in a blind-vs-blind spot, so 3-betting for value and to take initiative is strong. I'm raising to 10bb to play in position.

Call with pocket threes heads-up at this 3-bet size; the pair has implied odds to make sets and retains some showdown value against a likely wide blind-versus-blind range.

I flopped quads in a 3-bet pot and use a small continuation-sized bet to keep overpairs and broadway hands continuing while preserving room to extract later.

KQ suited with two overcards and a backdoor flush draw is getting good odds against a small 1/4-pot donk bet on a low paired board (500 to win 2500), so calling is profitable. Raising would mostly fold out worse hands and get called by better ones.

I have flopped quads and want to build the pot while still allowing queens, overpairs, and draws to continue.

Queens up with a king kicker is strong but not the nuts. AQ, QQ and 44 beat it, and raising mostly folds out the worse hands while getting called by better ones. Calling keeps their bluffs and weaker pairs in the pot.

I have quads, and a substantial river value bet can be called by aces, queens, and full houses while preserving a wider calling range than an all-in shove.

Second pair with a king kicker only needs about 24% equity to call 3000 into 9600. Villain's three-street donk line still includes missed spade draws, middle pairs and weaker queens. Raising would only get called by better hands, so calling is best.

7-5 offsuit is too weak to profitably enter from the button at this stack depth.

Q5o is a reasonable SB-vs-BB open in blind-vs-blind; raising to 3bb takes initiative and wins the pot outright often, while limping out of position realizes equity poorly.

T4o offsuit is weak; facing a raise with poor equity, folding is best.
