Hold'em table

Q8s suited on the button in a 3-max game is a standard profitable open; I raise to 3x to take initiative and apply pressure on the blinds.

6♦5♠ is a weak offsuit hand facing a button raise, and calling from the small blind would leave the big blind behind with action. Fold rather than defend out of position.

A4o plays poorly out of position against a 3bb button open, making fold a disciplined and standard defense adjustment.

J8 offsuit is a marginal but playable button hand three-handed; raising applies pressure from position and can win the blinds outright.

A3o plays poorly out of position against a button raise with the big blind still to act, making folding the standard play.

Eight-three offsuit is far too weak to defend against a 2.5x button raise even with a small call price; folding is clearly best.

Q7o is slightly too weak to open profitably from the button even 3-handed, making fold the standard play.

J-9 offsuit is playable heads-up from the small blind, and completing costs only 50 chips while keeping the pot small.

AQo is well ahead of a small blind limping range, so I raise for value and position.

J9 offsuit is a weak, dominated hand out of position against a substantial raise. The pot odds do not justify continuing.

T6 offsuit is marginal but playable from the button in a three-handed game. Raise to apply pressure and take initiative.

K2s is too weak to call out of position against a button raise with the big blind behind us.

Suited jack in the big blind against a 2.5x button open is cheap to see a flop with decent playability; folding is too tight three-handed, and 3-betting J8s out of position is riskier than calling.

I hold jack-high with no real draws on an ace-high flop against the preflop raiser, who very likely has an ace. Checking keeps the pot small and lets me fold cheaply to any bet.

T-high has little equity on this ace-high, two-heart flop, and checking preserves the chance to improve without investing into the big blind's range.

I only have jack-high with a gutshot to the queen; betting into a preflop raiser who likely holds an ace (pairing the board) has little fold equity, so I take the free card and give up if pressured.

I have a modest pair with a reasonable showdown value, but the ace-high board and flush draws make a value bet unattractive. I’ll take the free card and avoid building the pot.

The four-heart board makes many opponent hands a flush, and my pair of tens has little value as a bet. I’ll take the free showdown rather than risk chips.

43o is too weak to play even from the button in a 3-handed game. Clear fold.

K8s is strong heads-up and the button folded, so I'll raise for fold equity and position against the BB.

A2 offsuit is a reasonable big-blind defend against a small blind raise, and the price is favorable. I’ll call rather than inflate the pot with a weak hand.

I'm the preflop aggressor on a dry T62 rainbow board, so a half-pot continuation bet has good fold equity even though I only have king-high; I can easily fold if raised.

Bottom pair with an ace kicker has enough showdown value and backdoor potential to continue against a single flop bet. I’ll call rather than inflate the pot.

The 8d gives me middle pair on a dry, draw-light board; a small turn bet extracts thin value from 77/99/8x and denies gutters while keeping the pot manageable against a flop-calling range heavy on tens.

Bottom pair is weak, but the 400-chip bet is small relative to the pot and my ace kicker gives some showdown value. Calling is preferable to raising and keeps bluffs in the range.}

I have only a weak pair of deuces, and the river completes several straight possibilities. Checking keeps the showdown cost-free rather than risking a bet against a stronger hand.
