Hold'em table

T2o is well outside standard opening range on the button even 3-handed, making this a clear fold.

With K4 offsuit heads-up in the blinds and closing the action for only 50 more, calling realizes sufficient equity at a low price.

Q4 offsuit is too weak for a routine value raise against the small blind's limp. Checking takes a free flop while retaining positional advantage postflop.

With bottom pair on an ace-high board in a limped pot, checking controls the pot and preserves flexibility against the big blind.

Bottom pair has some showdown value, but betting this dry ace-high board is unlikely to get called by many worse hands. Checking keeps the pot small and preserves the option to improve.

With only a weak paired four on an ace-high board, checking keeps the pot controlled and preserves showdown value.

My pair of fours has some showdown value, but a bet is unlikely to get called by many worse hands. Checking keeps the pot small and lets me realize my equity in position.

We have only a weak pair of fours on an ace-high board after passive action. Checking realizes showdown value without risking a thin value bet.

Our pair of fours has some showdown value, but a river bet is unlikely to get called by worse. Checking avoids risking chips against higher pairs in this small pot.

J9 suited is a playable button hand three-handed, and a small open-raise can leverage position while building a pot with reasonable risk.

AQ offsuit is a strong three-bet against a button open in a three-handed game. Raising to 1200 pressures the big blind to fold and extracts value from the button's weaker hands while compensating for being out of position.

Facing an open and a substantial 3-bet from the small blind, T9o is far too weak to continue with out of position.

J9 offsuit is too weak to continue profitably against a large small-blind 4-bet after opening.

8-4 offsuit is too weak to open profitably from the button without evidence that the blinds overfold. Folding avoids investing in a hand with poor connectivity and limited postflop potential.

Folding 96o from the small blind as it is too weak to complete or raise out of position.

Q7o is at best a marginal open from the button in 3-handed play; folding is standard and avoids weak offsuit holdings.

Complete the small blind with 9-6 suited-equity potential against the big blind, keeping the pot small and realizing position postflop.

J8 suited is a reasonable isolation raise against a small-blind limp, with position and good postflop playability. Raising to 4 big blinds applies pressure while building a pot when called.

Offsuit 96 is too weak to defend against a large 4bb raise out of position heads-up.

Raise premium suited AK on the button to build value and apply pressure while keeping weaker hands in.

Seven-deuce offsuit is too weak to defend against a button raise from the small blind, especially with the big blind still to act. Folding avoids investing more chips with poor equity and positional disadvantage.

86o is too weak to defend out of position against a button raise.

T6 suited is strong enough to open on the button in a three-handed game. Raising to 2.5 big blinds applies pressure to the blinds while retaining positional advantage if called.

9c 2s is unplayable trash out of position against a button raise, so folding is trivial.

Defend the big blind with suited 86 against a button min-raise, as the price is favorable and this hand has strong implied-odds potential heads-up.

With only six-high on a paired king-high board against the preflop raiser, checking preserves equity and avoids bluffing into a range that connects well.

This dry, king-high paired flop favors my preflop raising range, making a small continuation bet an efficient bluff against the big blind's missed hands. I also have a backdoor heart flush draw if called.

Call the small continuation bet with a club flush draw and favorable pot odds, retaining positional information for later streets.

I have two pair on a coordinated board and can extract value from worse sixes, draws, and stubborn pairs while charging diamond and straight draws.

My sixes and fives have limited showdown value against this substantial turn lead, which can represent a king, trips, or better. With few reliable improvement outs and no evidence of frequent bluffing, calling is unlikely to be profitable.
