Hold'em table

I'm on the button with A3 offsuit; a standard raise to 250 isolates the blinds and leverages my positional advantage.

With A-9 offsuit in the small blind against a 2.5x button raise, I have a strong enough hand to apply pressure. Raising to 800 (4x the raise) gives me favorable odds and initiative while building a pot I can win preflop or continue playing with my ace-high leverage.

65 offsuit is far too weak to defend against a large open and a substantial 3-bet out of position.

A3 offsuit is too weak to continue against a sizeable 3-bet; folding preserves chips for better spots.

3-10o is a weak hand in early position. With the small blind already committed and big blind to act, folding is the standard play to avoid losing chips with poor equity.

A7 suited has strong enough equity heads-up against the big blind to complete from the small blind at this price.

I'm the big blind with a weak, unsuited-off-suit-ish hand (4s8s is actually suited but low), no raise to call, checking is free and keeps pot small heads-up against limper.

Betting the limped heads-up pot with a strong open-ended straight draw and ace-high equity applies pressure while building a pot when called.

Cheap call getting over 3:1 with a gutshot straight draw and backdoor flush outs, plus I'll have position for the rest of the hand.

I have a gutshot to the eight plus ace overcard equity, while the turn check gives me a credible opportunity to pressure unpaired flop floats and weaker pairs.

I only have a gutshot straight draw (need a 7) with no other backup outs; the pot odds do not justify calling a second barrel with such weak equity.

Pocket queens are a premium button holding and should be raised for value. A 2.5bb open builds the pot while retaining maneuverability.

Weak offsuit low cards facing a raise; not worth calling from the small blind.

4d8c is a weak hand facing a raise to 250 from the button. With only 100 chips already committed as the big blind, folding minimizes losses against a likely stronger range rather than calling 150 more chips with a marginal holding.

9-5 offsuit is a weak hand not worth playing from the button facing a raise; folding preserves chips for better spots.

6-Tc is a weak hand with no strong potential. Being in the small blind after seat_1 folded, I face a bet from the big blind. The hand is not worth playing, and folding minimizes losses against a strong range.

9-6 offsuit is a weak hand in early position. With 100 chips to call and no particular advantage, folding preserves chips for better opportunities.

6-3 offsuit is too weak to defend the small blind against the big blind at this stack depth.

Pocket sixes are a strong enough button hand to open-raise for value and isolation. A 3bb raise applies pressure while retaining maneuverability.

Weak offsuit low cards facing a raise, not worth continuing from the small blind.

J5o is a weak hand unsuited in the big blind. With seat_3 raising to 300 and seat_1 folded, calling 200 more gives poor odds and is not profitable against a raiser with our weak holding.
