Hold'em table

I have a suited connector on the button, raise to 300 to steal blinds and build pot with position.

Q5 offsuit in the small blind facing a 3bb button open is a clear fold; it's dominated often, plays poorly out of position, and the BB is still to act behind.

T6 suited is too weak to defend the big blind out of position against a 3x button raise; its equity and realizability do not justify calling 200.

T7o on the button in a 3-handed game is a reasonable steal candidate against two blinds; a 2.5x open applies pressure with position.

A8 suited is strong 3-handed against a wide button open; 3-betting from the small blind builds fold equity, likely folds the big blind, and avoids playing out of position in a multiway pot.

K6s is too weak to call a 3-bet out of position, and the pot odds of about 1.56:1 require around 39% equity, which this hand lacks against a strong small-blind 3-betting range.

T7 offsuit is far too weak to continue against a 3-bet from the small blind; calling 650 more out of position-neutral but with a dominated hand is unprofitable, and 4-bet bluffing with no blockers is poor.

J6 suited on the button in a 3-handed game is well within a profitable opening range, with position and suited playability. Raising to 2.5bb pressures the blinds and gives fold equity plus initiative.

K2o is too weak to defend from the small blind against a button raise, and playing out of position with a dominated hand would lose chips in the long run.

7-4 offsuit is a weak hand with poor playability out of position against a button open; folding is the standard play despite decent pot odds.

Standard button steal attempt with Q6s; three-handed gives good fold equity against blinds.

A9 suited in the SB facing a button open at 2.5x is a solid 3-bet candidate in 3-handed play; raising to ~3.2x isolates the button opener and denies the BB a cheap squeeze or call.

Q7 offsuit is weak facing a button raise and small blind 3-bet to 800; calling 700 out of position postflop has poor equity and reverse implied odds.

Q6s is too weak to call a 3-bet to 800 from the small blind, even in position, given the 2.09:1 pot odds and poor playability postflop.

J7 suited on the button in a 3-handed game is a standard open; raising to 2.5bb to take initiative and steal blinds.

T9 suited is too strong to fold 3-handed against a 2.5bb button open, and calling keeps a playable suited connector in the pot at good odds despite being out of position.

Q8o is too weak to call from the big blind facing a button raise and small blind call, especially out of position; pot odds of 20% are not sufficient given reverse implied odds.

Top pair with ten kicker on a draw-heavy 9-8-4 rainbow board; betting for value and protection against overcards and straight draws from the button raiser.

Donk bet from SB into the preflop raiser is often weak/medium; I hold a gutshot plus backdoor flush and an overcard in position, so a semi-bluff raise applies fold pressure while retaining equity when called.

Top pair with a ten kicker needs only 25% equity to call 700 into 2100, and I am ahead of many draws and weaker pairs in a button raiser's wide range.

Turn gives me top two pair on a very straight-heavy board. Betting about two-thirds pot gets value from overpairs and worse two pair while charging J, Q and 7 draws and denying a free river.

J7 makes a jack-high straight on 4-8-9-T, second nuts (only QJ beats us). Opponent is leading big into us and likely has a set, two pair, or a draw; the board has a flush draw, so I shove to deny equity and get max value with effective stacks covering.

Two pair tens and nines is vulnerable on the 8-9-T board, and opponent raised the flop then shoved over my turn lead for a huge overbet. That polarized line is heavily weighted to straights and sets, against which I have only about four full-house outs and need 34% equity to call.

8-4 offsuit is too weak to call or raise from the button in a 3-handed game, with poor equity and playability postflop.

K8o is a playable hand heads-up against the big blind, and raising puts pressure on the BB to fold or call out of position. A raise to 2.5x the big blind is standard to steal the blinds and take initiative.

76s in the big blind facing a small-blind raise to 2.5bb heads-up: getting 150 to win 350, with position postflop, suited connectors play well enough to defend by calling.

We have an open-ended straight draw with Kh8d on a QdJhTs board. Out of position, checking controls the pot and allows us to see a free card or call a reasonable bet with good implied odds.

I have 76 of clubs on a Q-J-T rainbow board with no pair, no draw, and no backdoor flush draw; the board heavily favors the preflop raiser's range, so betting as a bluff is poor and checking back is best.

Semi-bluff with open-ended straight draw on a wet board. We have good fold equity after checking flop, and can still improve on river.

7-high with no pair or draw on Q-J-T-2 board facing a 300 bet into 500; no equity to continue.
