Hold'em table

2c4s is a very weak hand with poor equity and playability, especially against two opponents. Folding preflop avoids investing chips with a hand that will rarely win at showdown.

Blind vs blind, Q5o is a reasonable raising hand from the SB against a single opponent; raising to 3bb applies pressure and takes the initiative.

AT offsuit is a strong heads-up blind-versus-blind hand. I 3-bet for value and to apply pressure against a likely wide small-blind opening range.

Q5o is too weak to call a 3-bet out of position; I'd be getting 600 into 1800, and this hand plays poorly and is dominated too often to justify the call.

62o is too weak to open from the button in 3-handed play against two blinds, so folding is the cheapest option.

Getting 3:1 pot odds heads-up, 8-5 offsuit is worth completing and realizing equity postflop.

I have a weak offsuit ace and already have my big blind in the pot. Checking lets me see a cheap flop with no additional risk.

A small continuation bet can profitably pressure the big blind's many unpaired holdings after their check. Our hand has little showdown value, so checking gives up too often.

I have top two pair (aces and jacks), which is likely best here. Raising for value against a weaker ace or a draw, while keeping the pot manageable if villain has a jack.

We have no pair, no meaningful draw, and virtually no equity versus a flop raise on this paired ace board. Folding preserves chips.

Pocket queens are a premium hand on the button. I raise for value and to narrow the blinds' ranges.

AK is strong enough to 3-bet for value against a button open; I'll raise to 1000 to take initiative and put pressure on the blinds.

62o facing a raise and a 3-bet with the original raiser still to act is a clear fold.

Queens are a premium holding heads-up against the small blind's 3-bet. A 4-bet to 2,700 builds value and applies pressure to weaker broadways and pairs.

7-4 suited is a weak hand with poor equity against two players; calling is -EV. Folding preserves chips.

52o is among the worst hands in the SB versus BB, and I'd play out of position; folding the extra 50 is the low-variance choice.

On the button 3-handed, K2o is a standard open against two blinds, so I'm raising to 2.5bb to steal.

9-5 offsuit is too weak to defend from the small blind against a button open, especially with the big blind still behind.

QTs is a strong suited hand and I'm getting good pot odds to call the small raise, especially with the small blind already folded. Calling keeps the pot manageable while seeing a flop in position relative to the raiser.

I have an open-ended straight draw with Q-T and a backdoor flush. Checking allows me to see a free turn or evaluate the opponent's bet, since I'm out of position with a drawing hand.

The ace-high board favors my button opening range. I hold the Kc blocker and have a backdoor straight draw, so a small c-bet puts pressure on the big blind's many misses.

Q3 offsuit is too weak to open from the button at this stack depth, especially against two blinds.

82 offsuit is a very weak hand out of position against the big blind, so folding saves chips with minimal loss.
