Hold'em table

6-2 offsuit is far too weak to open from the button under these stack depths.

A2o is a weak hand in 3-handed play, especially out of position on the button. Folding preserves chips and avoids marginal situations where dominated hands lead to chip loss.

62o is the worst starting hand and plays poorly out of position; folding avoids further investment despite the small blind already being posted.

42o is the worst starting hand in hold'em with very low equity even 3-handed and poor playability; folding preflop for 100 chips is clearly the highest-EV choice.

With the button folded, Q6 offsuit is strong enough to raise from the small blind heads-up and pressure the big blind's wide defending range.

On the button, 65 offsuit is a reasonable steal candidate against the blinds; raising applies pressure and retains positional advantage.

King-six offsuit is a weak hand, especially from the small blind against a raise to 250 chips (2.5BB). Folding avoids further losses in an unfavorable position.

With 6-3 offsuit in the big blind facing a button raise, this hand is too weak and dominated to continue profitably, especially out of position.

5-8o is a weak hand with poor win equity against likely raises from strong positions. Folding conserves chips for better opportunities, especially from the button where positional advantage is limited when acting out of position.

J4s is weak, but calling 50 into a 150 pot gives good odds to see a flop; raising would bloat the pot out of position with a marginal hand.

Check the big blind with Q5 offsuit in a limped pot; it has enough equity to see a flop without inflating the pot.

I flopped two pair (6s and 4s) and the board is paired; betting for value and protection against overcards/draws is best.

Q-high has two gutshot straight draws plus potential overcard value against a likely wide heads-up flop stab. Calling preserves flexibility with positionless but adequate equity.

With only queen-high and a gutshot, betting is preferable to checking behind. The paired board can make it difficult for an opponent with unpaired overcards or weak holdings to continue.

I have two pair with a J kicker, but the paired board and turn raise mean I could be behind to trips; calling controls the pot and keeps worse hands in.

With only queen-high, checking is unlikely to win. The river heart and paired board let us credibly represent a made heart or a stronger pair, and a substantial bet can fold many weak one-pair and missed-draw holdings.

Q8s is a reasonable button hand in a 3-handed game, and raising applies pressure on the blinds while taking initiative. A 3x raise is a standard size with position.

Kings are a premium hand; I 3-bet for value from the small blind and build the pot against the button's opening range.

4-3 offsuit is the weakest possible hand in hold'em. Facing a raise from seat 3 and a 3-bet from seat 1, I'm in the worst position with the worst hand. The pot is already bloated and my equity is minimal against likely stronger holdings.
