Hold'em table

84o on the button 3-handed is below a standard opening range at 100bb deep; folding is fine.

Pocket fives are strong heads-up against the big blind's random range, so I raise to apply pressure and take initiative while still allowing folds.

K6 offsuit is too weak to defend against a small-blind raise in this heads-up pot, especially out of position postflop.

A3 offsuit is strong enough heads-up versus the big blind, and raising applies pressure while leveraging the ace blocker.

Getting 2:1 in position against a small-blind open; 93s is a standard defend against a 3x raise in this spot.

I have top pair heads-up on a relatively dry board and should value-bet while charging weaker aces, pairs, and draws.

9-high with only backdoor draws on an ace-high board that favors the preflop raiser; it is too weak to continue even at 25% pot odds.

6-4 offsuit is a weak button holding; folding avoids entering a marginal pot.

A5o is a strong hand blind vs blind, so I'm raising for value and to take initiative. The ace blocker and wheel potential make it a clear open.

Jh8h is suited and getting 3:1 pot odds to call 200, so seeing a flop is profitable in a 3-handed game.

On a dry paired board, a small c-bet with ace-high plus a backdoor diamond draw works well as the preflop raiser. It can take the pot down now and keeps our equity if called.

I flopped trips with a jack kicker, so I'm raising for value and to charge any diamond draws or overpairs that might continue.

I have a diamond flush draw plus ace-high overcard outs. That is enough equity for the 27% pot odds on a 600 call, and there is no need to bloat the pot against a raise.

I have ace-high with a gutshot-free weak draw, and the villain's check-raise on the flop signals strength. Checking lets me realize equity cheaply and avoid bloating the pot out of position.

Ace-high has some showdown value, but the opponent raised the flop and then checked the turn by timeout. A mid-size bet can fold out small and medium pairs, and if they time out again the fallback rule folds their hand.

AJo on the button in 3-handed play is a clear open-raise for value; 2.5bb is a standard sizing.

5-4 offsuit is too weak to continue out of position against a button raise, especially with the big blind still to act. Folding preserves chips for better spots.

QTs has solid playability heads-up versus a button min-raise, and calling preserves its equity without bloating the pot out of position.

I have a very strong made hand on this coordinated flop and should build the pot while charging draws and one-pair holdings.

AJ on QT5 has a gutshot to the nut straight plus an overcard, facing a donk bet of 400 into 550. Calling is clearly profitable, and raising would bloat the pot against a range that often has a Q or T.

Betting two pair for value against Kx, Qx, and draws while charging hands that can continue. The coordinated board makes a larger bet appropriate for protection.

We hold the nut Broadway straight on a two-spade board, so we raise for value and to charge flush draws and two-pair or set hands.

The king turn strongly improves much of the button's flop-calling range, and the large raise over my turn lead is heavily value-weighted. Two pair has insufficient equity and poor river realization against that range.

Pocket nines are a strong heads-up blind-versus-blind holding. Raising for value and initiative is preferable to merely completing.

A8o in the big blind against a small-blind open is well ahead of a wide blind-vs-blind range. I'm getting 2:1 and will have position postflop, so calling is clearly profitable, and mixing in some 3-bets is also fine.

Betting small protects our pocket nines against overcards while extracting value from worse pairs and ace-high hands that may continue.

Ace-high on a dry paired board has decent equity against a small c-bet (200 into 600), and the price is good. Calling keeps SB's bluffs in and lets me realize equity.

With nines on a paired board, checking controls the pot and retains bluff-catching value against missed draws or weaker pairs.

Ace-high has decent showdown value against a range that checked after a small flop bet. Bluffing is unlikely to fold out the pocket pairs that beat us, so checking back realizes our equity cheaply.

Our nines have modest showdown value on this paired board, but a river value bet is likely called mostly by better queens or trips. Checking keeps weaker holdings in and avoids a thin-value spot.

Two pair (eights) with an ace kicker is likely best after the preflop raiser checked the turn and river. A small value bet can get calls from worse pocket pairs and ace-high while risking little against a Queen.

Call the small river bet with pocket nines; the checked turn leaves enough missed draws and weaker bluff-catchers in range.

Qs9s is a playable button hand with strong positional value. A small open raise pressures the blinds while keeping the pot manageable.

T7o in the small blind facing a button open with the big blind still to act is a clear fold: it's out of position and dominated too often.
