Hold'em table

A3 offsuit is strong enough to open on the button three-handed. A 2.5 big blind raise applies pressure while keeping the pot manageable.

A9o is a decent hand in 3-handed play against a button min-raise-ish open of 2.5bb. Calling 200 more is reasonable, though out of position with the big blind still to act. A 3-bet with this hand is marginal, so I'll just call.}

Holding 65 offsuit out of position against a raise and a call, the hand lacks playability and equity realization despite decent pot odds.

Ace-high on a paired low board, first to act out of position heads-up against a button raiser. A small bet of about half the pot takes the initiative and may fold out hands like king-high or an underpair, while limiting losses if I'm behind.

The half-pot bet gives me a reasonable price with a gutshot, an ace overcard, and position. I’ll call rather than inflate the pot with ace-high.

I hold ace-high with a gutshot-ish nothing on a paired board, so I have a marginal hand with some showdown value. Checking out of position controls the pot size against a button opener who called the flop bet.

Ace-high has some showdown value against missed draws, and a river 2 would complete a straight. Checking in position keeps the pot small while preserving the option to bluff or value bet on the river.

Ace-high on a 5-5-4-T-7 board is mostly a showdown-value hand, but the opponent checked back the turn, so their range is weak. A small thin bet of about a third of the pot could get worse hands like 9x or small pairs to fold, or call and lose to us. It risks little if we are behind. Checking is also reasonable, but the small bet picks up some fold equity. ,

The small river bet gives ace-high a good price to bluff-catch after the turn checked through. My 3 also blocks some possible straights.

T3 offsuit is a weak hand out of position against two players in a three-handed pot. Folding gives up nothing worth keeping, and calling or raising with it has negative expectation.

In a blind-versus-blind scenario with A7s, opening with a standard 3x raise is optimal for value and taking initiative.

The small blind can raise a wide range, and 8♠4♠ has enough equity and postflop playability to defend in position for 200 more chips.

On a connected low board that favors the big blind's calling range, checking with gutshot and overcard allows me to realize equity comfortably out of position.

The preflop raiser checked a flop that connects well with my defending range. A half-pot bet can win now, and my gutshot gives me equity when called.

I have a gutshot straight draw to the nuts, an overcard ace, and backdoor nut flush potential; getting 3 to 1 pot odds makes calling profitable.

Check out of position on the turn with our ace-high and gutshot straight draw to see what the opponent does.

I have an eight-out straight draw. Betting can fold out weak hands that called the flop while building the pot when I improve.

We have a gutshot straight draw with an overcard, needing 28.6% equity to call an 800-chip bet into a 2000 pot, but our direct draw offers only ~9% equity out of position.

I hold pocket queens on the button and enter the pot with a standard 2.5bb open raise for value.

4♠2♠ is too weak to defend from the small blind against a button raise, especially with the big blind still to act.

4-8 offsuit is a weak hand; calling 150 to win 400 gives about 27% pot odds, but I'd be out of position against a button raiser with poor equity and playability, so folding is best.

Nine-five offsuit is too weak to open from the button against two players with full stacks.

Button folded, so I'm heads-up against the big blind with T6o. Only 50 more to call for a pot of 150 (3:1), and being closed out of the raise by a mostly random range makes calling a reasonable price, though the hand is marginal. I'll complete and play postflop carefully.

I check my option with pocket threes in the big blind to see a cheap flop in position.

Ten-high with no pair or real draw on an Ace-Queen-8 flop; checking keeps the pot small and I act first heads-up out of position against the big blind, who checked preflop and may hold a wide range.

With bottom pair/low underpair on an Ace-high board in a limped pot, checking back to see a free turn is standard.

I have only a gutshot draw (T with A-Q-J-8 needs a K) and no showdown value. Checking keeps the pot small and lets me see the river cheaply, and a bluff into a checked-through big blind isn't clearly profitable.

I have bottom pair with very low equity on a broadway-heavy board; checking behind to see a free river is standard.

Ten-high with no pair on a paired, connected board is essentially a pure bluff-catcher. Both players checked the flop and turn, so the opponent's range is capped and weak. Checking is safe, and a bluff is unlikely to fold out hands that beat ten-high.

The board plays two pair eights with Ace-Queen-Jack kickers, meaning we chop against almost all of opponent's unpaired low hands without risking a bet.

9-6 offsuit is a weak hand out of position postflop against two opponents on the button, so folding is the safer choice than calling 100 to see a flop.

Holding weak offsuit rag cards 6h 3s in the small blind, it's a clear fold even getting 3:1 pot odds.

Opening with a pocket pair on the button is standard in 3-handed play. A 2.25bb open is well-sized for 100bb stacks.

Nine-deuce offsuit plays poorly out of position against a button raise, especially with the big blind still to act.

J5 offsuit is a weak hand. Calling 125 to win 375 gives about 25% pot odds, but I would be out of position with poor equity against a button open that is likely wide, so folding is fine.
