Hold'em table

7-3 offsuit is a very weak button hand and not worth entering against two blinds at this stack depth.

KQs is a strong hand in blind-vs-blind, so it should be raised for value. A 3x open is a standard size from the small blind.

JTo has enough equity against a wide small blind opening range and I'm getting 3:1 pot odds, so calling is profitable.

On a paired, dry J55 board, we hold two overcards plus a backdoor flush draw, and we have the range advantage as the preflop raiser. A small c-bet of a third of the pot should take this down often while keeping our equity.

J7 suited is a reasonable button open in 3-handed play, so I'll raise to 2.5bb to take the initiative and attack the blinds.

A5o is dominated by many of the button's raising hands and I'm out of position, so calling is likely to lose chips over time. Folding preserves my stack for better spots.

54 offsuit has poor equity and playability against a button open, especially out of position. Folding avoids defending too wide.

Pocket eights are strong enough to raise from the button and put pressure on the blinds. A raise to 300 builds the pot while keeping control of the hand.

Ten-six offsuit is too weak to defend from the small blind against a button open with the big blind still to act.

32o is the worst hand to defend out of position against a 3x button open; needing 200 to win 650, it realizes too little equity to call profitably.

4-high suited is too weak to profitably open from the button in this short-stack-reset format.

A2o is a clear opening hand in a blind-vs-blind spot, so I raise to 3bb for value and fold equity rather than limping.

Q7 offsuit is a weak hand out of position against a raise, and calling 200 more with only 400 in the pot is not profitable. Folding preserves chips for better spots.

76o on the button 3-handed is a standard open; a small raise to 2.5bb puts pressure on both blinds.

3-4 offsuit is too weak to continue against a raise out of position, so folding preserves chips.

9-high offsuit with a weak kicker is too weak to defend against the button raise, especially out of position.

2-10 offsuit is a weak hand and not worth investing chips preflop, even with position on the button. Folding preserves my stack for better opportunities.

Getting a very favorable price in the small blind against the big blind, Q4 suited is sufficient to complete and see a flop heads-up.

77 is well ahead of a small-blind limping range, so raising for value and initiative in position is better than checking.

Q4 offsuit is too weak to defend from the small blind against a 4bb raise, especially out of position.
