Hold'em table

On the button in 3-handed play, Q8o is strong enough to open for a steal. Raising to 2.5BB pressures the blinds and wins the pot often; if called, I still have position.

A3o from the SB against a button open is a reasonable 3-bet bluff candidate, since the ace blocker plays better as a raise than a flat out of position with the BB still to act. Sizing to 10bb.

6-2 offsuit is far too weak to defend against a large open and 3-bet.

Q8o is too weak to continue against a 3-bet from the small blind, and I would be out of position facing a large bet.

T3 offsuit is too weak to open profitably from the button in a 3-handed game with 100bb stacks, even with only the two blinds left to act. Folding is the standard play.

A suited ace with a strong queen kicker is well ahead of the big blind's random range heads-up. Raising builds value and applies pressure while keeping the pot manageable.

5-7 offsuit is too weak to continue out of position against a 3bb raise, and it has poor playability postflop. Folding preserves chips rather than calling with a dominated hand.

Button open with suited ace; raising applies pressure and leverages positional advantage.

Q9 offsuit is a weak hand out of position against a button open, and the big blind can still act behind me. Folding avoids paying 2bb with poor playability postflop.

Getting 150 to win 400 (27% equity needed) against a button open, which is likely a wide range; 97o has enough equity and playability to defend from the big blind.

Middle pair on an ace-high board, out of position against the preflop raiser, who will c-bet often. Check with the plan to call a reasonable bet, since the hand has showdown value and a backdoor draw.

Betting top pair for value against weaker aces, nines, and draws while keeping the sizing small enough to retain those hands.

Middle pair against a small c-bet (200 into 550) gives me good pot odds, and button c-bets wide on an ace-high board. Calling keeps his bluffs in and controls the pot size.

Second pair on an ace-high turn that just brought a queen has showdown value but is weak against a button that c-bet the flop. Checking keeps the pot small and lets me decide on a turn bet with pot odds.

I have top pair and should value-bet against weaker aces, queens, and draws while charging equity. A medium sizing keeps worse hands in and protects my hand.

Third pair with a weak kicker on an A-Q-9-5 board is too weak to call a second barrel. The button's betting range here is heavily weighted toward Ax and Qx, and I have few clean outs.

Pocket eights are a strong hand heads-up from the small blind against the big blind, so I raise to 3bb for value and initiative. Limping would give the big blind a cheap look at the flop.

Ac2h is worth defending from the big blind against a small blind min-raise at this price, with position postflop.

Out of position with 88 on a Q-J high board that connects well with the big blind's calling range; checking controls the pot and keeps some showdown value.

The preflop raiser checked a board that often misses or gives up, so I will make a small heads-up continuation stab with ace-high and some backdoor club potential.

Small bet (1/3 pot) gives good odds of 200 into 800; 88 on a Q-J-3 board has decent showdown value against a BB defending range that stabs often. Calling keeps their bluffs in without bloating the pot.

Pocket 8s on a J-Q-J board have showdown value but are vulnerable to overcards, and villain bet the flop. Checking controls the pot size and keeps villain's bluffs in.

With only ace-high on a paired broadway board, checking takes the free showdown equity and avoids running into the opponent's many Qx and Jx continuations.

88 has showdown value on a paired, Q-high board but gets called by few worse hands if we bet. Checking keeps the pot controlled, and we can bluff-catch a small bet from the big blind's turn-check range.

Ace-high has some showdown value against missed straight draws and other unpaired hands after the opponent's passive turn and river line. A bluff lacks useful blockers to their likely Qx/Jx calling range.

T9s on the button in 3-handed play is a clear open-raise; 2.5bb puts pressure on both blinds while keeping us in position.

5-2 suited is too weak to defend against a button open from the small blind at this sizing.

K9o is playable heads-up in the big blind with good pot odds, so I call to see a flop rather than fold or inflate the pot with a marginal hand.

I have only king-high on a paired board, so checking keeps the pot small and lets me see the turn for free.

On the button with T9 suited on a 677 board, I have an open-ended straight draw (an 8 completes it). A small c-bet of about a third of the pot pushes out overcards and uses my range advantage, while my equity holds up if called.

JTs is a strong, playable button opening hand three-handed. I raise for value and initiative with a modest standard sizing.

Q2o is too weak to continue against a button raise, especially with the big blind still to act behind me. Folding preserves chips for a better spot.

The price is good: 150 to call into a pot of 400 needs about 27% equity. K2o holds up well enough against a wide 3-handed button range to defend by calling from the big blind.

Two pair on a dry K-high board. Checking to the preflop raiser invites a c-bet that I can check-raise, and it keeps his bluffs in the pot.

With only jack-high on a dry king-high board after the caller checks, I check back and retain equity rather than bluffing into an uncertain range.

Top two pair on a board where the button checked back the flop, which caps their range, so I lead the turn for value. A bet around 64% pot also charges flush draws and weaker Kx.

We have second pair with a jack kicker after the checked flop, and the turn sizing is small enough to defend in position. Calling keeps weaker bluffs and draws in while avoiding an inflated pot against stronger kings or tens.

Top and bottom two pair is well ahead of a range that checked back the flop and called the turn, which is full of Kx and Tx. The river brick is mostly safe (only A3/36 make a straight), so I bet about 64% of the pot for value.

Top pair is a reasonable bluff-catcher at this price after the flop checked through. The turn-and-river line can contain missed draws and weaker one-pair hands, so folding needs too much certainty.
