Hold'em table

T9s on the button in a 3-handed game is a clear open; raising to 2.5bb takes initiative and plays well in position against the blinds.

Jack-three suited is too weak to continue against a button open with the big blind still to act, so folding is the highest-EV option.

Defend the big blind heads-up versus a small button raise with suited Q6; the price is favorable and the hand has playable equity.

This flop strongly favors the preflop raiser and Q-high with no heart has little immediate value. Checking preserves flexibility and avoids building a pot with a weak hand.

Top pair on a monotone board with no heart; a small c-bet (~1/3 pot) gets value from worse pairs and single-heart draws while keeping the pot manageable.

With no heart and only weak overcard equity on a monotone board, continuing versus the preflop raiser's continuation bet is unprofitable.

74s is too weak to open from the button for 100 chips into a 150 pot; folding preserves the stack.

Q2 suited is worth completing from the small blind heads-up for the excellent price, while keeping the pot small with a dominated-prone hand.

Button folded, small blind limped; 76o is a weak but playable hand with position postflop, so taking a free flop is better than bloating the pot with a raise.

Betting half pot can fold out many unpaired hands while retaining equity with two overcards to the board's lower ranks.

Open-ended straight draw (any 5 or T) facing a half-pot bet; getting 3:1 immediately with ~32% equity to improve by river plus implied odds, so calling is clearly profitable.

I improved to trip queens and should value-bet against weaker queens, pairs, and draws while charging the many straight and spade draws.

Open-ended straight draw (any 5 or T) with 8 outs; direct odds are slightly short but with 9500 behind the implied odds justify a call heads-up against a small turn bet.

I have a queen pair on a paired board and can target calls from weaker queens, nines, and curious bluff-catchers. A moderate river value bet keeps those hands in while limiting losses against an eight.

Missed open-ended straight draw; 7-high has no showdown value against a river bet after three streets of aggression, and a bluff-raise into a likely made hand is poor.

Open the button with 8-7 offsuit, which has reasonable playability and positional value in three-handed play.

Q6 offsuit in the small blind facing a 2.5x button open is a clear fold; it's dominated and plays poorly out of position.

3-5 offsuit is too weak to continue against a button open; folding avoids putting more chips in with a dominated hand.

T3 offsuit on the button is a weak, unsuited, disconnected hand that is outside a standard 3-handed button opening range; folding avoids playing a dominated hand out of position against two players.

86o is too weak to complete out of position against the big blind after the button folds; the extra 50 is not worth playing a dominated offsuit hand.

7-5 offsuit is too weak to open from the button against two live blinds, so folding preserves the stack.

Pocket eights is a strong heads-up blind-versus-blind hand. I raise for value and to deny the big blind an easy realization of equity.

9-5 offsuit is a weak hand facing a 3x raise from the small blind; calling 200 to see a flop out of position with poor playability is unprofitable, so fold.

5-3 offsuit is too weak to profitably enter from the button at this stack depth.

Button folded, so it's SB vs BB heads-up; J4o is a marginal but playable hand in a blind-vs-blind spot where a raise takes the pot down often and keeps initiative, better than completing out of position.

73s is too weak to continue against a preflop raise, even heads-up after the button folded.
