Hold'em table

K2 offsuit is a weak button holding in this structure and not worth entering against two blinds without reads.

5-3 offsuit is one of the weakest holdings in poker. With only 50 chips invested (small blind), folding preserves my stack for better opportunities in upcoming hands rather than risking additional chips against the big blind with a marginal hand.

T6o is a weak hand in early position, especially out of position. Folding conserves chips for better opportunities while maintaining a tight image.

With the button folded, it's effectively heads-up against BB; Js8s suited plays well here, so I raise for value/isolation.

Pocket sevens are well ahead of a small blind opening range heads-up and benefit from building the pot while denying overcard equity. I 3-bet to a standard size.

J8s facing a 3-bet to 900 from BB after my open is weak; not worth continuing given the reraise size and out of position with a marginal suited hand.

J4 offsuit from the button facing a call is a weak hand not worth continuing with three-way action; folding preserves chips.

8-4 offsuit is too weak to continue from the small blind against the big blind.

T9 suited is a playable button open in a three-handed game, and raising applies pressure while retaining positional advantage.

AK is a premium hand and I'm in position with the small blind. Seat 1's raise to 300 looks like a standard opening; I can apply significant pressure here and build a pot I'm happy to win immediately or continue with my strong hand.

8-5 offsuit is weak; facing a 3-bet to 1000 with weak reverse implied odds, folding is correct.

T9 offsuit is too weak to continue versus a large 3-bet, especially with the opponent representing a strong range.

Queen-seven offsuit is a weak hand in early position. With blinds posted and a need to call 100 chips, folding preserves chips for stronger opportunities.

Heads-up pot, cheap to complete with a marginal hand; no need to raise weak offsuit cards.

AQ suited is a strong heads-up hand against a small-blind completion, and raising builds value while denying equity to a wide limping range.

J5 offsuit facing a 4x raise from a wide-ish spot is not worth continuing, especially out of position.

Q6 offsuit is weak in a 3-handed pot facing action from both blinds already in; better to fold on the button rather than invest here.

J5 suited has sufficient equity to complete heads-up at this price, while avoiding inflating the pot out of position with a marginal hand.

I'm in the big blind with Q-3o (weak hand). Seat 3 folded, and seat 1 called. Checking keeps the pot small with a marginal holding and allows me to see the flop for free to evaluate my position post-flop with board texture and implied odds.

This weak unpaired hand has little value betting into the big blind on an ace-high flop. Checking preserves equity and avoids building a pot with minimal showdown value.

With Q-3o on Ad-2h-Ts flop, I have no made hand and weak queen-high. Checking allows me to see the turn cheaply while maintaining flexibility; betting would be unwarranted with poor showdown value.

A small turn stab can fold out unpaired high-card hands after the flop checks while risking little. I retain a gutshot to the wheel if called.

I hold 3c-Qc, which is a weak hand with no significant draw on a board of Ad-2h-Ts-4s. Seat 1 (small blind) has bet 100 on the turn, indicating strength. Calling would require another 100 chips with poor equity, and raising is not profitable against a likely stronger holding. Folding is the optimal play.
