Hold'em table

Q9 offsuit is a reasonable button opening hand in three-handed play. Raising applies pressure to the blinds and retains initiative.

T4o is a weak hand that doesn't warrant calling a 250-chip raise from an aggressive raiser (seat_1). With no strong equity against a raise, folding preserves my stack for better opportunities.

Button steal with Q4o; blinds are likely to fold, and we have position if called.

With pocket sevens (a medium pair), I have a decent hand that plays well against two opponents. Raising aggressively forces seat_2 to make a difficult decision and allows me to take control of the pot, especially since my 3x raise is reasonable given the stack sizes and current action.

5-3 offsuit is far too weak to continue facing a 10bb 3-bet out of position, especially with the opener still behind.

Q4o is too weak to continue against a sizable small-blind 3-bet, and calling 700 more out of position postflop would be a losing proposition despite having already invested 300.

8-7 offsuit (actually suited but weak hand) is below my folding threshold in this position. With the small blind and big blind already committed and no strong implied odds, folding preserves my stack for better opportunities.

8-3 offsuit is too weak to defend from the small blind against the big blind, even heads-up.

Fold the weak 3-4 suited button hand rather than entering a likely multiway pot with poor high-card strength.

Completing the small blind with 3s8s is profitable given the 3:1 pot odds, and I can evaluate a cheap flop out of position.

With 8h-Ts (weak unpaired hand), checking is prudent in a 3-way pot from the big blind. This allows us to see the flop cheaply and avoid committing more chips with a marginal holding. Seat 1 has folded and only seat 2 remains active.

I flopped middle pair on a dry board and will bet small for value and protection while taking the initiative.

8-10 offsuit is a weak hand on a dry flop. Seat_2 raised to 100 on the flop showing strength, and calling would put me in a difficult position with poor equity. Folding preserves chips for better opportunities.

9-5 offsuit is too weak to open or call from the button in a 3-handed pot; folding avoids investing chips with a low-equity, poorly connected hand.

With 8d9d (connected cards with suited potential), raising to 300 from the small blind after seat_2 folded gives me better pot odds and initiative. This is a reasonable semi-bluff with decent equity to improve, and folding would waste the blind already committed.

A♠Q♦ is a strong heads-up blind-defense hand versus a small-blind open; 3-betting builds value and applies pressure to a wide opening range.

8d9d is a weak hand facing a 3-bet to 900 from an aggressive opponent. With only 9700 chips and needing to call 600 more, folding preserves my stack for better spots.

Q2o is a weak hand in early position (button/facing blinds). With only 100 chips to call and marginal hand strength, folding preserves chips for better opportunities.

9-high offsuit with a four is too weak to defend profitably from the small blind against the big blind.
