Hold'em table

Q6o is a weak hand in early position. Folding preserves chips for stronger opportunities, as this hand has poor win rate against likely 3-bet ranges.

With the button folded, J8 offsuit is strong enough to raise from the small blind heads-up and pressure the big blind's wide range.

Weak offsuit low cards facing a raise with a player already folded; not worth defending BB here.

7-3 offsuit is a very weak button opening hand in a 3-handed game, so folding avoids playing a dominated, low-equity pot.

68 offsuit is weak, button folded but BB still to act; not worth completing with a marginal hand out of position.

On the button with Ax offsuit, a standard raise to build the pot and take initiative against two limpers/blinds.

4-2o is one of the weakest hands in poker. Facing a 3x raise from the button, folding is the correct play to preserve chips and avoid playing out of position with a dominated hand.

J4 offsuit is too weak and dominated to profitably defend out of position against a 3bb button open.

J9 suited is a reasonable hand from the button with potential to improve postflop. Raising to 3x isolates the blinds and allows us to play positionally with a wider range, while folding here against moderate blind pressure would be overly passive.

4h3d offsuit is too weak to defend from the small blind against a button 3x open with the big blind still behind.

A7o has decent equity heads-up against a standard button open, and the pot odds justify a call rather than folding or raising.

I have ace-high with a backdoor draw on a dry-ish board; checking to see a free card and control pot size out of position.

I have a pair of nines on a 9-8-3 board, which is currently the best hand. Seat 3 checked, indicating weakness, so checking allows me to control pot size and see the next card while maintaining my lead. This is safer than betting into a hand that might have folded anyway.

Ace-high with no pair or draw on this board; checking to see a free card is best.

I have 9d-Jd with a pair of nines on a 9s-8d-3h-2s board. My hand is moderately strong but vulnerable to potential draws or overcards. Checking preserves value and allows me to control pot size; if seat_3 bets, I can reassess. There's no immediate threat to check back given the dry turn and my positional advantage.

Both opponents checked flop and turn showing weakness; my pair of 7s with top kicker likely has value, so a modest bet extracts value from weaker hands while limiting risk against a possible slow-played monster.

I hold 9d Jd (pair of 9s on a 9-8-3-2-7 board), but seat_3's river raise into the checked-through flop and turn strongly suggests a strong hand, likely better than my pair. Folding preserves chips in a losing spot.

J9 offsuit is a reasonable button opening hand three-handed; raising applies pressure and retains initiative.

9d7d suited connector-ish but facing a raise from button with BB still to act behind me; not worth calling out of position for marginal value.

I hold AK, the strongest hand in poker. Seat 2 raised to 220 from the button, and seat 3 folded. I need to repop this aggression with a strong 3-bet to build the pot and control the action with my premium hand.

J9 offsuit is too weak to continue profitably against the big blind's substantial 3-bet, even with position.

J2 offsuit is a weak hand not worth playing from the button facing a raise-sized call; folding preserves chips.

3-2 offsuit is the worst hand in poker. Facing a big blind bet with a hand this weak, folding is the only rational play.
