Hold'em table

T9 suited is a strong, playable button opening hand three-handed. I raise to apply pressure and build the pot in position.

Jd3s is too weak to call a button open from the small blind with the big blind still to act.

Q6 suited in the big blind facing a 2.5x button open with 150 to call into a 400 pot gives good odds and closing action; it's a standard defend.

Q6 offsuit with no heart on a monotone Th3h5h board out of position; I have nothing but Q-high, so checking to the preflop raiser and evaluating is best.

Betting top pair for value and protection on this highly coordinated monotone flop. A modest sizing keeps worse pairs and draws involved while limiting exposure to made flushes.

Q6 offsuit with no heart on a monotone Th3h5h board has only a weak gutshot-less backdoor; facing a c-bet out of position with little equity, folding is correct.

74s is too weak to open from the button for value or as a bluff; folding avoids building a pot with a dominated suited rag.

Button folded, so it's SB vs BB heads-up; Q2 suited is a standard raise from the small blind in a blind-vs-blind spot to take initiative and often win the pot preflop.

Defend the big blind against the small blind's wide heads-up opening range; 7-6 offsuit has sufficient playability and pot odds.

Q2o completely whiffed on a wet, connected 9-8-4 two-tone board that favors the BB's calling range; with no draws and little equity, checking out of position avoids bloating the pot with air and keeps the hand cheap.

We flopped an open-ended straight draw with two overcards to the board's low pair structure, giving us substantial equity and fold equity. A two-thirds-pot continuation bet pressures overcards and weaker one-pair holdings while building a pot when called.

Q2 offsuit-ish (Qd2d, no spade draw) missed the 9s8s4h flop entirely; facing a 400 into 600 bet with just queen-high and no draw, folding is clearly correct.

7s8o on the button in a 3-handed game is a reasonable open-raise; it has playability and I have position for the rest of the hand.

Q-six offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still behind.

3-5 offsuit is too weak to continue against a button open, especially out of position.

T3 offsuit is too weak to profitably open from the button at these stack depths.

86o is too weak to play out of position against the big blind after the button folds, so I give up the small blind rather than continue.

75o is too weak to open from the button for a full big blind; folding preserves chips.

Pocket eights in the small blind vs big blind heads-up after button folds is a clear value raise; 3x open keeps initiative and builds pot in position-less spot with a strong hand.

9-5 offsuit is too weak to defend against a small-blind 3x raise heads-up out of position.

5s3h offsuit on the button is well below a standard open range even in 3-handed play; folding avoids a negative-EV spot.

J4 offsuit is a weak blind-versus-blind holding and does not justify continuing out of position.
