Hold'em table

Opening from the button with Q8o, which falls within a standard 3-handed button opening range.

Only 150 more to call into a 350 pot gives excellent odds, and A3o has reasonable equity against a wide button opening range. Folding is close, but the price justifies defending from the small blind.

62 offsuit is too weak to continue out of position against a raise and a call, even at a cheap price.

I only have top pair with a weak 3 kicker on a two-tone board and act first postflop, so checking keeps the pot small; I can call one bet but don't want to bloat against stronger aces, AQ, or sets.

I have second pair with a mediocre kicker on an ace-high board. Checking back controls the pot size and allows me to realize showdown value in position.

I flopped two pair (aces and threes) and should build the pot while charging club draws; betting around 70% of pot extracts value from weaker aces like AK without committing too much against sets or AQ.

Second pair with a weak kicker and no club redraw does not have sufficient equity or river playability to continue against a turn lead.

T3 offsuit from the button is too weak to play out of position against two blinds; folding is the standard play.

Button folded, so this is heads-up versus the big blind with AQo. A small value raise builds the pot and denies a free flop.

75o is too weak to defend against a 3x SB open, even in a blind vs blind confrontation.

A3s is playable from the button against unopened blinds, so I open to 2.5bb to take the initiative and fold out worse hands.

Q9o is too weak to defend out of position against a button open with the big blind still left to act.

9c7d is dominated trash facing a 2.5x raise out of position; calling with 150 more has poor implied odds. Folding is clearly best.

K2o is too weak to open raise from the button 100bb deep.

Pocket eights from the SB are strong enough to raise for value and fold out weaker limps; a small raise keeps the pot manageable.

Ace-deuce offsuit is too weak to continue out of position against a three-big-blind raise, so folding avoids a dominated spot.

T9s is a strong button open in a 3-handed game; raising to 3x builds the pot with a playable suited connector and puts pressure on both blinds.

52s is too weak to call a button raise from the small blind with the big blind still to act, so folding is the highest-EV line.

K9o has sufficient equity against a wide button open in 3-handed play getting better than 2:1 pot odds.

Check out of position to the preflop raiser with King-high on a paired board.

As the preflop raiser on a paired low board that mostly misses the big blind's calling range, a small continuation bet applies pressure while I hold a gutshot, two overcards, and a backdoor flush draw; I can easily fold to a raise.

I completely missed this paired flop with King-high and have minimal equity or backdoor potential out of position, making an easy fold against the continuation bet.

JTs is a strong suited connector on the button, so I open to 3bb to take the initiative and build the pot against the blinds.

Q2o is far too weak to defend out of position against a 3bb button raise.

K2o is dominated by a 3bb open range and out of position; calling 200 to win 450 with a weak king-high is -EV.
