Hold'em table

I'm on the button with a small pocket pair; raising to 300 builds the pot and isolates while keeping it manageable for a potential set-mine or continuation.

Holding 8c 4d in the small blind facing a 3bb open from the button is a clear fold.

A5s in the big blind getting 450 into 200 (about 2.25:1) against a button open is a clear call. It has good playability, and the button's range is wide, so I'll defend and see a flop rather than 3-bet out of position.

Top pair with ace kicker-ish (A5) on a 9h Ah Jd board, heads-up out of position against a button opener. A flush draw is possible, so I bet about 60% of the pot for value and protection.

Low pocket pair with no equity on an A-high board facing a raise; folding is best.

96 offsuit is too weak to open profitably even from the button in a 3-handed game.

J8 suited in the small blind getting 3-to-1 on a call of 50 into a pot of 150 against a single big blind. Calling is clearly profitable, and raising with a marginal hand is unnecessary.

I'm BB with weak offsuit low cards (3h2h is suited actually, but still weak); no raise needed, just check since SB only called.

Heads-up on a 7-Q-7 flop with J-high and a backdoor flush draw, I hold a pair-less hand with some equity. A small probe bet of 100 into 200 can take it down against a range that often misses, and I'm first to act with the opponent checked to.}

Weak holding (32 suited hearts, missed board) facing a bet on a paired board; folding is cheap and preserves chips.

J8 offsuit is a weak hand out of position against two players still to act behind me in the blinds' ranges; folding avoids a marginal spot, though on the button a call is close.

Heads-up against BB with an Ace, a standard raise to build pot and apply pressure.

94s is too weak to defend against a 3bb raise from the small blind, despite being suited.

96o is a weak hand; folding to avoid committing chips with a poor preflop holding in 3-handed play.

In a blind-vs-blind situation, A6o is strong enough to open-raise for value and pressure the big blind.

J4 offsuit is weak. Facing a small-blind raise to 300, calling out of position is marginal, and the pot odds (200 to win 500) don't justify it with a hand this poor. Folding costs only the 100 already posted.

Open-raising suited Ace on the button in 3-handed play to steal blinds and take initiative with position.

QJo out of position in the small blind facing a button open and a big blind still to act is marginal. Calling 200 more with a likely squeeze behind is unattractive, so I fold.

3h5d offsuit is a weak hand facing a raise; folding is correct rather than calling with a marginal low-card holding.

4c5s is a weak offsuit hand. Calling out of position against two players for 100 into a 150 pot is marginal at best, and folding costs nothing.

9-4 offsuit is weak; folding small blind is cheap when facing just the big blind heads-up with a marginal hand.
