Hold'em table

6-5 offsuit on the button facing a raise in a 3-handed pot is a weak, unsuited, unconnected hand not worth defending; fold to preserve stack.

A5o is a standard button open against two blinds; raising to 2.5x applies pressure and builds the pot with position.

Queen-ten offsuit out of position against a button raise is a marginal defend, and the big blind can still squeeze. Folding avoids a poor realization spot.

Pocket jacks are strong heads-up value against a single opener; 3-betting builds the pot and denies easy equity to weaker hands.

A5o is far too weak to continue against a 3-bet to 850 after my button raise; calling 600 into a small pot with a dominated ace is -EV. Folding preserves chips for better spots.

J4o is too weak and poorly connected to open from the button against two live blinds, so folding avoids a dominated spot.

Heads-up now that the button folded; A2o plays fine against just the big blind, so I raise to build the pot and apply pressure.

64 offsuit is a very weak hand that is dominated by most raising ranges, and calling 150 more out of position with poor playability is unprofitable. Folding is the clear choice.

I'm on the button with QJ offsuit, a decent hand in a 3-handed game; raising to isolate and take initiative.

T9o from the small blind against a 3x button open is dominated too often and plays poorly out of position with the big blind still behind. Folding is standard despite decent raw equity.

35s is too weak to continue out of position against a button open; calling 200 into 450 does not justify the reverse implied odds.

King-Queen offsuit on the button is a strong opening hand; raising to 3bb builds the pot with position and isolates the blinds.

K3 offsuit is too weak to continue out of position against a button open; folding avoids a dominated, poorly connected hand.

3h5h is a weak suited connector-ish hand facing a 3x raise from the button; not worth defending out of position for 200 more given weak equity and reverse implied odds.

46o is too weak to open even on the button in a three-handed pot; folding avoids playing a dominated offsuit hand out of position postflop.

Heads-up now with A5o, a decent hand; raising from the small blind to isolate against the big blind.

K7s has decent playability and I act last postflop against the SB raiser; calling 200 into a 400 pot is cheap with a suited king, while folding is too tight and 3-betting is too thin.

Ace-high with no pair or draw on a wet two-flush board; checking to control pot size out of position.

I have a king-high flush draw plus a gutshot on the flop, and the preflop raiser checked to me, so a half-pot semi-bluff builds the pot, protects my equity, and can win it outright.

Ace-high with no pair, no flush draw, and a scary two-spade flop; not worth continuing against a bet.
