Hold'em table

Calling the big blind with Q8 offsuit in the big blind position is a standard, low-risk play to see a flop without overcommitting. I will continue postflop with position advantage.

AJ offsuit is strong enough to raise for value from the small blind after a limp; sizing to build pot while limiting multi-way risk.

T6o is too weak to continue against a preflop raise; folding avoids putting more chips in with a dominated offsuit hand.

I have Q8 offsuit in the big blind position after a raise to 400. The pot odds don't justify calling with this weak hand, and I'd rather preserve my stack for better spots.

Q7 offsuit on the button facing a raise-less pot with SB and BB still to act is a weak, non-premium hand; folding preserves chips.

Queen-six offsuit is too weak to complete or raise out of position against the big blind after the button folded. Folding saves the extra half-blind for better spots.

Q6 offsuit is too weak to open from the button; it is dominated often and plays poorly postflop, so folding is the higher-EV choice.

I have a suited connector in position with a folded opponent, so calling the small blind to see a flop is a low-cost way to realize potential equity without overcommitting preflop.

I'm the big blind with weak 6-2 offsuit and no raise to face; checking to see a free flop is the standard, cheapest option.

I have a backdoor flush draw with 6h7h on a ThJsQc board, but no made hand. Since I can check and there's no cost, I'll see the turn card for free while keeping my options open.

No pair, no draw, and board is coordinated; checking behind is cheapest way to see turn.

The board is dynamic with a flush draw possible, and I hold a gutshot straight draw plus backdoor flush potential. Checking keeps the pot small and lets me see a free river card while preserving my stack.

Weak hand with no pair and a scary board; checking to see a free river is best.

The board is King-high with a Ten-Jack-Queen straight draw that missed; my 6h7h is a weak high-card hand with no made value. Checking is the safest play to avoid building a bigger pot with a marginal hand against a likely stronger range.

Only a weak pair of sixes on a scary board; no value in betting, just check it down.

I have a suited Ten with a backdoor flush draw and gutshot, which is playable but not strong enough to raise. Calling 100 keeps the pot manageable and lets me see a flop without overcommitting.

Pocket deuces are ahead of a wide button limp, and a small isolation raise builds the pot heads-up while taking the initiative.

I hold 2c-Tc, a weak hand that is dominated by seat_3's preflop raise to 400. Folding avoids losing more chips with poor equity against a likely strong range.

Weak offsuit hand (T4o) from the button facing a raise-limpish pot with two players still to act; not worth investing chips.

Button folded, so this is heads-up versus the big blind. Q7 suited has enough equity and playability to raise for initiative rather than complete out of position.

My hand (Tc2d) is weak and unsuited, and I am out of position facing a raise. Folding preserves my stack for better opportunities.

Js5s is suited and playable as a button open in three-handed poker, so I raise to 2.5bb to take the initiative with position rather than limp or fold.

I have Td2c, a weak offsuit hand, and face a raise to 250. The pot odds and hand strength don't justify continuing, so folding minimizes losses.

Q5 offsuit facing a raise is too weak to continue, easy fold from the big blind.
