Hold'em table

On the button with 8-7 offsuit, I can close the action cheaply for 100 chips and keep my options open to see a flop in position.

K6o is too weak to continue out of position against a button limp and the big blind still to act, so I fold rather than complete.

I have J4 offsuit in the big blind facing a limp and can see a flop for free.

I have J-high with no draw on a paired queen flop out of position, making an easy check.

I hold 8-7 offsuit with no pair against a paired board of Q-Q-3, so checking keeps the pot small and avoids investing chips with a weak hand.

I hold J-high with no significant showdown value or draws, so checking to see a free river card is standard.

I have no pair on a Q-Q-3-6 board, so checking is free and keeps the pot small without risking chips.

I hold second pair with Queens and Jacks on a checked-down board. Checking gives good showdown value and keeps the pot manageable.

I hold 8-7 high with no pair on a Q-Q-J-6-3 board, so I have little showdown value. Checking is free and avoids building a pot I can't win.

J6s is playable as a button open in three-handed poker; a 2.5bb raise steals the blinds with position and suited equity.

Folding K6o from the small blind against a button open; out of position with weak offsuit holdings is unprofitable.

Ace-eight offsuit closes the action with a good price of 150 to call into a 400 pot, and it is a playable hand to see a flop from the big blind against a button raise.

I have only ace-high on a J-T-6 board, so I can take a free card and keep the pot small rather than bloat it without a made hand.

I flopped two pair on a dryish board and the big blind checked, so a value bet of about three-quarters pot builds the pot while keeping worse jacks and tens in.

Ace-high with almost no straight or flush equity against a button raise after a flop check-raise line, and the call of 400 into a 950 pot needs more equity than this hand has.

Opening from the button with Q9o to apply pressure on the blinds in 3-handed play.

Holding 4s 2s out of position facing a 250 raise, calling 200 needs roughly 31% equity and this hand is well below that against a button raising range, so folding is the disciplined choice.

T3s is too weak to continue out of position against a button open; folding saves chips.

K9 offsuit is a reasonable button steal against two blinds in a 3-handed game, and a raise to 250 applies pressure while keeping the price low.

75o is too weak to continue from the small blind against a button open; folding saves chips.

In 3-handed play, J9o has sufficient equity and pot odds (calling 150 to win 400) to defend the big blind against a standard button open.

I missed the low paired board entirely with J9 offsuit out of position; checking to the preflop raiser is standard.

I have only King-high on a board pairing the fours, and seat_3 already checked, so checking keeps the pot small and avoids bloating it without a made hand.

I have Jack-high with no draw on a paired board; checking is standard out of position to see what opponent does.

I have only King-high on a paired board, so checking keeps the pot small and takes a free river card rather than bluffing into a player who has checked twice.

With only Jack-high, we have virtually no showdown value against the button's opening range. After both players checked flop and turn, the opponent's range is capped, so a bet of 300 into 550 can credibly represent a made hand and fold out better unimproved high cards.

I hold only King-high on a paired board facing a 300 river bet into 850, and villain's check-check-bet line likely means a made hand, so I need more equity than I have to call.

Q4 offsuit is too weak to open from the button for a full big blind, so I fold and wait for a better hand.

K3o has poor playability out of position against the big blind, making an easy fold.

95o is far too weak to open on the button, even in 3-handed play.

King-three suited is a playable hand heads-up against the big blind, so I raise to isolate and build the pot with initiative.

JTo has enough equity and playability versus a small-blind steal to defend the big blind for 200 into a 400 pot.

Top pair of kings heads-up against one opponent, so betting for value is reasonable on this dry board. A 400 bet into a 600 pot charges draws without overcommitting.

I have middle pair with a jack kicker and position, and the pot odds justify continuing against a single flop bet rather than folding or raising thin.

I have only a pair of kings with a weak kicker against a caller who may hold an ace or better, so checking keeps the pot controlled and avoids bloating it with a marginal hand.

I have middle pair on an ace-king board after the opponent checked the turn, so checking keeps the pot small and realizes showdown value without bloating.

We hold two pair (aces and kings) on a paired-ace board, which is likely best or close to it against a passive opponent who only called the flop and checked the turn, so a value bet of about half pot is reasonable.

Board pair of aces plus a king means my tens are crushed by most of a value-betting range, and there are few natural bluffs after a dry runout. 700 into 1400 is not enough to call.
