Hold'em table

9♣3♦ offsuit is too weak to open from the button, especially with both blinds still to act.

Holding King-Queen suited in the small blind after the button folds is a clear value raise against the big blind.

T6s is too weak to continue against a 3bb small-blind raise; folding avoids a dominated, low-equity spot.

Pocket sevens on the button in 3-handed play is a clear opening raise for value and position.

J9o is too weak to continue out of position against a button open, with the big blind still to act. Folding avoids a dominated spot and a bloated pot.

KTs is a strong hand against a button open and has good playability postflop. Calling the 150-chip difference keeps weaker hands in and avoids bloating the pot out of position.

This dry, low flop misses my hand, and checking keeps the pot controlled while allowing the preflop raiser to act.

Check back on a dry board to control the pot with second pair and realize showdown value in position.

With only king-high and a gutshot to a jack-high straight, checking preserves the chance to realize equity without investing into a range that may have queens or better. I can reconsider bluffing if the river stays favorable and action checks through.

Check back with third pair to control the pot and realize showdown value in position.

With king-high on a dry board, checking preserves showdown value against missed hands and avoids bluffing into pairs or ace-high that may not fold.

Pocket sevens have moderate showdown value after both players checked flop and turn; betting won't be called by worse.

T3o is too weak to open even from the button in a three-handed game, so folding is the highest-EV line.

With the button folded, 8♠4♠ is weak but has enough equity and playability to complete from the small blind at this price.

AJo is well ahead of an SB open-limping range, so raising to 3.5bb builds the pot with an equity and positional advantage.

84 suited is too weak to defend against a raise to 3.5 big blinds from the big blind, even with the small blind already invested.

A9 offsuit is strong enough to open from the button. A 2.5× big blind raise applies pressure to the blinds while keeping the pot manageable.

K4o is too weak to defend out of position from the small blind against a button open.

75 suited is too weak to continue out of position against a button raise, so folding preserves chips.

84s is too weak of a three-gap suited hand to open profitably from the button in 3-handed play.

9-5 offsuit is too weak to complete out of position against the big blind, so I fold the extra 50 rather than play a dominated hand.

A5o is a reasonable button open in three-handed play with position, so I raise to 2.5bb rather than flat or fold.

K3 offsuit is too weak to defend out of position against a button raise, especially with the big blind still to act.

J6o is too weak to defend out of position against a 2.5x button open.
