Hold'em table

Q8o on the button in 3-handed play is a standard open; a small raise attacks the blinds.

AJs is a strong three-handed holding and benefits from applying pressure to the button open. Raising to 8bb builds value while retaining room to fold if facing extreme resistance.

Weak offsuit hand with no draws facing a raise and re-raise; calling 700 out of position is too expensive. Folding preserves my stack.

Q8o is well behind a small-blind 3-bet range, and we'd be out of position... actually in position, but the hand is too weak and dominated to call 550 more profitably.

Q7 offsuit is a weak button opening hand in this short-handed configuration, and folding avoids playing a dominated range.

I'm getting 4-to-1 pot odds heads-up against the big blind with a playable hand, so calling is cheap and profitable.

ATo is well ahead of a small-blind limping range, so raise to 4bb for value and to take the initiative in position.

Q6o is too weak to continue against a raise to 400, and calling 300 more offers poor equity against the big blind's raising range. Folding preserves chips for better spots.

Q6o is a weak hand; folding from the button avoids investing chips with a dominated hand.

Blind vs blind with suited connectors, a raise to 3bb takes the initiative and has good equity. It also puts pressure on the big blind's wide defending range.

6-2 offsuit is far too weak to defend against a small-blind raise, even with the favorable price.

T2 suited is near the bottom of a 3-handed button opening range and plays poorly against two blinds with deep stacks, so folding is fine.

With the button folded, 9-8 suited-equivalent connectivity has enough heads-up playability to raise from the small blind. A 3x big blind sizing applies pressure while retaining maneuverability.

Calling 200 with pocket deuces offers good pot odds and strong implied odds if I flop a set against the small blind's raise. Folding is too weak and raising with 22 is unnecessary at this stack depth.

A small continuation bet protects our middle pair and can fold out unpaired overcards while keeping the pot manageable on this king-high board.

T4 offsuit is too weak to open profitably on the button in a three-handed game at this stack depth.

On the button with a suited hand, I can apply pressure and try to take down the blinds preflop with a cheap raise while keeping position.

T2 offsite is too weak to defend from the small blind against a button min-raise, especially with the big blind still left to act behind me.

Defend the big blind against a minimum button raise with Q-high suited; the price is low and the hand has reasonable postflop playability.

Check top pair to retain the opponent's bluffs and avoid inflating the pot out of position on a coordinated board.

The opponent checked to me on a Q-high flop, so I can take down the pot with a continuation bet. My J-high has little showdown value, so a bluff is better than checking.

Top pair is well ahead of the button's small continuation bet on this relatively dry board. Calling keeps worse queens and bluffs in while avoiding needless inflation.

Checking keeps the opponent's bluffs and weaker hands in range while controlling the pot with a marginal top pair. I can evaluate their turn sizing before committing more.

I have no made hand or meaningful draw on this turn, and my opponent called a flop bet, so checking keeps the pot small and lets me see a free river.

I have top two pair on a dry board after villain checked back the turn. A medium river value bet can be called by weaker queens, single-pair hands, and curious bluff-catchers.
