Hold'em table

T3o is a weak offsuit hand with poor playability, and calling 100 chips from the button is not profitable enough to justify continuing.

6s7s is a weak hand in heads-up play against the big blind. With only 50 chips to call and no premium holdings, folding preserves chips for better opportunities in future hands.

8-T offsuit is a weak hand in early position that doesn't warrant investing chips. With a small blind and big blind already committed, folding is the prudent choice to preserve stack equity.

Q3 offsuit is a weak small-blind holding versus the big blind, and completing offers poor realization out of position.

Pocket fives are a solid button opening hand three-handed. Raising to 3bb applies pressure and builds value while retaining maneuverability.

Calling 250 into 450 with K8o; button's 3-handed open range is wide enough to justify a call despite being out of position.

Q4o is a weak hand in a 3-player game. Seat 3 raised to 300 and seat 1 called; facing 200 more to call into a 700-chip pot with a marginal hand out of position, folding is the prudent choice to preserve chips.

With king-high and no strong draw on a coordinated flop, checking keeps the pot small and avoids building a pot out of position against the preflop raiser.

Betting the overpair for value and protection on this moderately connected board after the caller checks. The small sizing keeps worse pairs and draws involved.

J9s is a playable button hand, so I open-raise to 3x to apply pressure on the blinds and take initiative.

T4o is a weak hand that doesn't warrant calling a 3x raise from the button. Folding preserves chips and avoids playing a marginal hand out of position.

8-4 offsuit is too weak to defend against a button 3x open heads-up from the big blind.

T-J offsuit is a reasonable hand in this 3-handed button position. Raising to 3x the big blind (300 chips) gains information, applies pressure to the blinds, and allows us to take down the pot immediately or play in position post-flop. This is a standard aggressive raise with a decent holding.

7-3 offsuit is too weak to defend against a button raise, especially out of position. Folding preserves chips for better spots.

On the button, T9 suited is a strong enough playable hand to open-raise and leverage position. A 2.5bb raise pressures the blinds while keeping weaker holdings in.

6-10 offsuit is a weak hand with poor winning potential against an early position raise of 250. With only 100 chips invested (big blind), folding preserves chips for better opportunities and avoids playing out of position postflop.
