Hold'em table

37o is too weak to call or raise from the button for a full big blind, so folding preserves chips.

Button folded so we're heads up against the BB; KQ suited plays well as a 3x squeeze to build a pot while retaining fold equity.

In a blind-vs-blind battle with position, JTo has plenty of equity and playability getting 2:1 pot odds to call a standard raise.

As the preflop raiser on a dry J-high board, a half-pot continuation bet is standard: my range dominates J55, and KQ retains fold equity plus overcard/backdoor equity if called.

Flopped top pair with a decent kicker against a half-pot c-bet in a blind-versus-blind pot; calling keeps their bluff range wide.

KQ-high has no pair and no live straight draw (I'd need both an A and T with only one card to come), so a second barrel into a flop-calling range full of fives, jacks, and pocket pairs has little fold equity. Checking keeps the pot cheap and wins only if they check back and I out-show an A-high float.

We hold top pair with a ten kicker on a paired board; checking behind controls the pot and allows us to see the river safely.

We hold fives full of jacks on the river. Betting 400 targets thin value from underpairs and takes advantage of the opponent's prior timeout.

J7s on the button has good playability and position against two blinds; a standard 3x open applies pressure and can win the pot preflop or build with a suited hand in position.

A5 offsuit plays poorly out of position against a standard 3x button open with the big blind still to act behind us, making it an easy fold.

54 offsuit is too weak to defend out of position against a button 3x open; calling needs more equity and playability than this hand has.

Opening with a pocket pair on the button is standard value play.

T6o is too weak to call a button open from the small blind, and it plays poorly postflop, so folding is the highest-EV option.

32 offsuit is the worst starting hand and calling 150 more out of position against a button raise has no equity edge or postflop playability. Folding is clearly best.

43s is playable from the button in three-handed, so I open to 2.5bb to take the initiative with position rather than limp or fold.

A2o offsuit is dominated too often against a button raise with the big blind still to act; calling out of position risks kicker problems, so folding loses the least.

Q7o is too weak to defend profitably out of position against a 2.5bb button open.

Suited connector on the button in a 3-handed game has good fold equity and plays well in position postflop; a standard 3x raise pressures the blinds without risking much of my 100bb stack.

Holding 43 offsuit out of position facing an open raise is an easy standard fold.

9-5 offsuit is too weak to continue out of position against a button raise, so folding is the highest-EV option.

Ten-deuce offsuit is well below the button opening range even 3-handed. Folding is the standard disciplined play.

Q4o is too weak to call or raise out of position against the big blind, so I fold and save the remaining stack.
