Hold'em table

Q8 offsuit is a reasonable button opening hand three-handed. Raising applies pressure to the blinds and retains initiative.

3-Ace offsuit is a weak hand that doesn't warrant continuing against a raise to 250 from early position. Folding preserves chips and avoids playing out of position with a marginal holding.

6-2 offsuit is a trash hand facing a raise; folding is correct even from the big blind facing additional cost.

T3o is a weak hand that plays poorly out of position. Folding is the standard play against a raise and small blind, especially with no promising situation ahead.

AQ offsuit is a strong hand heads-up against just the big blind after the button folded; raising builds the pot and takes initiative.

7-5 offsuit is too weak to defend against a small-blind 3x open at this stack depth.

Button raise with Ad3d, a suited ace with good playability against two blinds.

Qs9d is too weak to defend from the small blind against a button open with the big blind still behind.

9-7 offsuit is a weak hand facing a 2.5x raise from the button after the small blind folded. Folding preserves my stack for better spots.

K2 offsuit is a weak button opening hand in this short-handed spot and performs poorly when called. Folding avoids entering a marginal pot.

With pocket eights in the small blind after the button folded, I have a strong hand that's ahead of most ranges. A 2.5x raise is a standard aggressive play that builds the pot while applying pressure preflop, giving me good value and initiative.

T9 of hearts is a decent connector with flush potential. Raising to 400 from the button applies pressure and lets us play profitably in position against the blinds. This is a standard button raise that builds the pot when we have a playable hand.

Weak offsuit low cards facing a 4x raise from the button with another player yet to act; folding is best.

Defend the big blind against the button's modest 4bb open with K9 offsuit heads-up; it has sufficient equity and playability at this price.

Check to realize equity with the king-high club flush draw on this paired board while keeping the pot manageable out of position.

I have T9h on a 6-7-7 board, giving me an open-ended straight draw with two overcards. Checking allows me to see the turn cheaply while keeping the initiative; if my hand improves, I can bet aggressively later. Seat 1 has checked, so there's no immediate pressure.

The ace is a strong range card after the flop checks through, and my club provides useful equity if called. A medium-sized probe can fold out pocket pairs and unpaired hands.

I hold T9o, a weak hand with no strong draw prospects on this board. My opponent raised the turn after checking the flop, suggesting strength. With only a gutshot (needing a K for a straight), I cannot justify calling 500 chips against likely a stronger holding.

JTs is a decent button steal/value hand; raise to build pot and take initiative against blinds.

Q2 offsuit is too weak to defend from the small blind against a button raise with the big blind still behind.

King-deuce offsuit is a weak hand. Seat 3 raised to 250 from the button after seat 1 folded, indicating strength. Calling 150 more chips with a marginal hand out of position against a likely stronger range is not profitable long-term.
