Hold'em table

K7o on the button 3-handed is a standard open; a 2.5bb raise pressures the blinds.

2-Jack offsuit is a weak hand from the small blind facing a raise to 250. Folding is prudent against the aggressor's bet, preserving chips for stronger opportunities.

Closing the action with ace-high against a small button raise, I have enough equity and pot odds to call rather than fold or bloat the pot out of position.

Ace-high on a paired king-high flop has some showdown value but no need to bloat the pot out of position against the preflop raiser; checking keeps the pot small and lets me see a turn.

Top pair on a dry paired board, checked to me in position. A small c-bet gets value from worse kings, threes-less hands and draws, and denies equity.

Ace-high with no pair or draw on a paired king-high board is too weak to continue against a preflop raiser's flop bet.

9-3 offsuit is one of the weakest hands in poker. Even in late position on the button, this hand has poor win equity against the small blind and big blind. Folding minimizes losses early in the match.

Closing the preflop action for 50 into 150 with a suited hand; pot odds are good enough to see a flop heads-up.

J6o is a marginal hand; checking keeps me in position against the small blind's limp and lets me see a free flop. Raising it would be thin.

Betting small on an A-high flop to take down the pot; our hand has no showdown value and opponent likely missed.

Jack-high with no draw on an ace-high board isn't worth calling even at 3:1, and bluff-raising into a range full of limped aces is unprofitable.

8-2 offsuit is too weak to call 100 with only 2.5:1 pot odds, even on the button.

A9s is a strong hand in a blind-vs-blind spot, so I'm raising to 3bb for value and initiative.

9-Jack offsuit is a weak hand. Seat_1's raise to 300 from small blind after button folded suggests strength. Folding preserves chips in a marginal situation.

J3o is below a reasonable 3-handed button opening range at 100bb, especially with two players left to act behind me.

5-8 offsuit is a weak hand. Folding the small blind preserves chips against an opponent who has position and has already committed to the pot with a raise.

4-9 offsuit is a weak hand out of position on the button. Folding avoids putting chips into a pot with poor equity against likely better hands from the small blind and big blind.

J9o has a significant equity edge against a random big blind, and the button has folded. A min-raise to 200 builds the pot while keeping the big blind's calling range wide, maximizing value with our marginal made hand.

Facing a min-raise from the SB, I only need about 25% equity, and I'll have position postflop, so 42o is a profitable defend.

I have middle pair plus a flush draw on a monotone board, so betting for value and protection against overcards and weaker draws is best.

A diamond on the turn or river gives me a flush, though a low one, and a 5 gives me the wheel straight, so I have about 12 outs. Paying 250 to win 900 is a reasonable price to see the turn.

I have two pair and want to charge flush draws and get value from Ax with a diamond. Betting 600 into 900.

I have a 2-high flush draw plus a gutshot to the wheel, roughly 12 outs. Calling 600 into 1500 needs about 29% equity, and deep stacks add implied odds, so a call is close but fine. Raising would bloat the pot with a draw that is often dominated by higher diamonds.

I have two pair but the board is highly coordinated with a diamond flush and straight possible; checking controls the pot and avoids getting raised off my marginal showdown value.

I have zero showdown value with 4-high. My calls on the monotone board represent a flush, and villain checking the river after two barrels shows weakness, so a 70% pot bluff should fold out many hands.

Opponent called flop and turn then raised river on a coordinated board; my two pair is likely behind straights, flushes, and better two pairs. Folding to the 1500 raise.

Three-handed on the button, J7o is playable; raising applies pressure and takes initiative with position.

64s from the small blind facing a button open, with the big blind still to act behind, is a marginal hand that plays poorly out of position. Folding is cleaner than calling, and 3-betting as a bluff here is not clearly profitable.

4-2o is the worst hand in poker. Against a button raise to 250 and facing a 150 chip call, folding is the only rational play. Even if seat_3's raise is a bluff, 4-2o has virtually no equity and will lose money long-term.
