Hold'em table

7-3o is the worst hand in poker and has poor win equity against any reasonable hand. With no special position advantage and the need to maximize chip EV over the session, folding is the mathematically correct play.

KJs is a strong hand in a heads-up blind vs blind situation; raise to 300 to take initiative and build the pot.

Q9 suited is strong enough to defend the big blind against a small blind min-raise heads-up, with good playability postflop.

I flop top pair with a king kicker and a backdoor spade draw; as the preflop raiser, I'll bet for value and protection.

The small flop continuation bet is likely made with a wide range after the blind-versus-blind preflop action. Q9 has a gutshot plus some overcard and future bluffing potential, making a call preferable to folding immediately.

Villain’s flop c-bet followed by a turn check leaves substantial range weakness on this coordinated board. A half-pot stab credibly represents a J or stronger made hand and can fold out overcards and underpairs.

With top pair and a king kicker, I have enough equity to call the 700 bet given the 3:1 pot odds. Raising would likely only get called by better hands and fold out worse, so I prefer to call and evaluate the river.

Q-high has little showdown value, but the opponent's turn call makes a river bluff unlikely to succeed often enough. Check and take the free showdown.

2d7d is a weak offsuit hand facing a full big blind call from the button, so folding avoids unnecessary risk with poor playability.

7-3 offsuit is too weak to defend from the small blind against the big blind at this stack depth.

J2 offsuit is too weak to profitably enter against both blinds from the button at this stack depth.

5-3 offsuit is a very weak hand in poker. Even as the small blind with only 50 chips to call into a 150 chip pot, the hand is unlikely to win and folding minimizes losses in a weak position.

J8o is a weak hand in early position (button in 3-player game). Folding preserves chips against aggressive blinds, as this hand has poor win rate without favorable board texture.

QTo is strong enough to raise from the small blind against a single big blind, applying pressure and taking initiative.

7-4 offsuit is too weak to defend against a small-blind raise out of position.

KTo is a strong enough button hand in a 3-handed game to open-raise and apply pressure on the blinds. A raise to 300 builds the pot while keeping my range ahead of random blind defenses.

7-4 offsuit is too weak to defend from the small blind versus a button 3x open, especially with the big blind still to act.

K6o is a weak hand facing a 3x raise from the button. With only 100 chips invested and a significant skill disadvantage in a heads-up situation with a poor holding, folding minimizes losses and preserves chips for stronger spots.

7-5 offsuit is a weak button hand against two blinds and is not worth entering at this stack depth.

3c-Jc is a weak hand that lacks strong potential. Folding the small blind against a big blind who hasn't shown weakness is the correct play when facing a 50-chip call into an already contested pot.
