Hold'em table

2c4s is a very weak button hand in a 3-handed game and not worth entering without a compelling exploitative reason.

The button folded, so I can apply pressure on the big blind with a modest raise. Q5o is worth taking initiative with here, and I can win the pot preflop or continue selectively on the flop.

ATo is well ahead of a wide small-blind min-raise range, so I 3-bet for value and to take the initiative in position.

Q5 offsuit is too weak to continue against a 3-bet for 500 more, so folding preserves chips.

Holding 2d6s is very weak and not worth investing chips to call the big blind. Folding preserves my stack for better spots.

Blind vs blind, 85o is a reasonable open-raise from the SB against a single opponent; raise to 3bb to take initiative, and it plays poorly as a limp out of position.

A2 offsuit is strong enough to defend the big blind against a small blind 3x open heads-up, with favorable pot odds and position postflop.

The dry A-J-J board favors my preflop raising range, so a small one-third-pot continuation bet can fold out many of the big blind's weak hands at low risk. My 8-high has little showdown value, which makes it a good candidate to bluff.

Top two pair is well ahead of many ace-x hands and smaller pairs that can continue. Raising builds value while charging potential overcards and draws.

I have 8-high with no draw on an A-J-J board, facing a check-raise from the big blind. Calling 500 into 1500 has little equity, and re-bluffing into a strong range is too costly.

QQ on the button is a premium hand, so I'm opening to 2.5bb to build the pot and get value from both blinds.

Ace-king offsuit is a premium hand that benefits from building the pot and denying equity while out of position. A 9bb three-bet applies pressure to the button opener and the big blind.

6-2 offsuit is a terrible hand facing a raise and a re-raise; calling 800 more is not profitable.

QQ on the button is well ahead of a small-blind 3-bet range in 3-handed play, so I 4-bet for value while keeping stacks deep enough to fold to a shove if needed.

AK is a strong 5-bet shove candidate heads-up versus a button 4-bet, gaining fold equity while retaining solid equity when called.

QQ needs about 39% equity to call. Against a 3-handed 5-bet shoving range that includes AK and some looser hands, it should meet or beat that price.

7h4h is too weak to profitably open from the button at this stack depth; folding avoids playing a dominated hand.

Blind-vs-blind with 95o. A small raise works as a steal against a single big blind and plays better than a passive limp out of position.

QTs is a strong heads-up blind-defense hand with position after the flop, and calling preserves the opponent's wider raising range.

Bottom pair out of position on an ace-high, two-spade board has showdown value but can't comfortably handle a raise. Checking keeps the pot small and lets me bluff-catch.

Betting half pot applies pressure to missed hands after the preflop raiser checked, while retaining equity with a gutshot to Broadway.

Getting 4:1 against a small third-pot bet, bottom pair has enough equity against a wide big-blind range that includes draws and air, so a call is justified.

Bottom pair with no draw on a board where the Ks completed the flush draw and helped broadways, facing a flop bettor. Check to control the pot and realize showdown value cheaply.

I have a Broadway straight and can value bet against many one-pair hands that checked the turn. A modest sizing limits exposure on the four-spade board, where a check-raise would represent substantial strength.

Bottom pair on an A-K-J board with three spades, facing a second barrel, is almost always behind and has very few clean outs, so it can't reach the roughly 23% equity needed to call.

Q3o sits at the very bottom of a 3-handed button opening range and plays poorly against two blinds, so folding is the low-variance choice with near-equal EV.

8-2 offsuit is too weak to complete from the small blind against the big blind.
