Hold'em table

On the button in three-handed play, 7-8 offsuit is a playable opening hand with useful straight potential. A standard raise applies pressure to the blinds and can win the pot uncontested.

5-10 offsuit is a weak hand facing a raise from the button; not worth calling from the small blind.

On the button with a suited-ish connector (T-J offsuit), a standard raise to isolate the blinds and take initiative is profitable in a 3-handed game.

6-9 offsuit is a weak hand with poor playability. Facing a 250 chip raise from the button and a big blind still to act, folding preserves chips for better opportunities.

K5 offsuit has sufficient equity and playability to defend the big blind against a button 2.5x open heads-up.

I have a made king-high flush on a paired board and should value-bet while charging diamond and pair-based hands. A moderate sizing keeps worse holdings involved.

I hold three jacks (trip jacks) with strong kickers on a paired board, a near-nut hand, so I want to build the pot and extract value from single-pair or two-pair hands while still being able to fold to a shove if a full house is out there.

I have a diamond flush draw plus a gutshot to a king-high straight, giving sufficient equity and implied odds to continue against the flop raise.

With only a gutshot to Broadway and no made hand after the flop raise, I check back to realize equity and avoid betting into a potentially strong checking range.

I hold trip jacks (Js plus board Jh,Jd) with strong kickers, a very strong hand on this action-heavy board; betting builds the pot for value against likely worse trips, two pair, or draws, while still leaving room to fold to a monster reaction.

With only a weak king-high draw facing a large turn barrel after a flop raise, the pot odds and likely opponent strength do not justify continuing.

5-6 offsuit is a weak hand with poor win probability. Folding from the button preflop against posted blinds is the standard play with weak holdings.

Heads-up from the small blind, A7 suited is strong enough to raise for value and initiative.

K2 offsuit facing a raise with a player already folded isn't worth defending; folding avoids putting more chips at risk with a weak hand.

Qs8s is a suitable suited broadway hand to open on the button three-handed, applying pressure to the blinds while retaining postflop playability.

2-10o is a weak hand in a 3-handed game, and facing a 250-chip raise from seat_1 (which represents a significant commitment of 2.5BB), folding preserves chips for stronger holdings. The risk-reward doesn't favor calling or re-raising here.

Q7 offsuit is a weak hand from the button facing action; not worth calling with two players still to act behind.

Q7o is a weak hand out of position in a 3-handed game. Folding the small blind costs only 50 chips and avoids playing a marginal hand against the big blind's likely stronger range.

Q8 suited is a reasonable heads-up blind-versus-blind raising hand, and applying pressure can win the dead blind immediately.
