Hold'em table

Seven-three offsuit is one of the weakest hands, and folding it from the button avoids a marginal call of 100 chips with poor playability.

52 offsuit is near the bottom of my range and plays poorly out of position against the big blind. Without evidence that a steal would succeed often enough, folding avoids investing more in a weak hand.

A small button raise uses position and the king blocker to attempt a low-cost blind steal. K3 offsuit is marginal, so keeping the raise small limits exposure against stronger continuing ranges.

K6 offsuit is weak out of position facing a raise; not worth continuing for more chips.

Calling the 100-chip raise with 9-7 suited in the big blind gets good pot odds heads-up against a button open, and the hand has reasonable playability postflop.

I have 9-7 high with no pair on a 6-2-Q board, so I'm not strong enough to bet for value. Checking keeps the pot small and I can see the next card for free.

This dry queen-high flop favors the preflop raiser's range, making a small continuation bet an efficient bluff against the big blind's many missed hands. Betting one-third pot can win immediately while limiting exposure with weak showdown value.

I have only a gutshot plus a backdoor flush draw out of position, which doesn't justify calling 150 into a 600 pot against a preflop raiser who is betting again.

6-9 offsuit is a weak hand from the button facing a raise to 100 with two players already in; folding preserves chips for better spots.

Three-eight offsuit is a weak hand to play out of the small blind against the big blind, and the 50-chip completion doesn't justify the postflop difficulty.

A3 offsuit on the button is a playable steal spot against a small blind and big blind, so I raise to isolate and build the pot.

97 offsuit is too weak to continue profitably from the small blind against a 3bb button raise, especially with the big blind still to act. Folding avoids investing more chips out of position.

63 offsuit is too weak to profitably open from the button against two blinds at 100bb depth. Folding avoids investing in a hand with poor equity and playability.

Q2 offsuit is a weak hand not worth playing from the button facing a raise-less but unimproved position; folding preserves chips.

Getting 3:1 on the 50-chip call heads-up against the big blind, and 4-9 offsuit has roughly 40% equity against a random hand, so calling is slightly profitable without rake.

J5 offsuit is too weak for a routine isolation raise against the small blind's limp. Checking lets me see a free flop in position without building a pot with a marginal hand.

My 4c9h has no pair and no real draw on a J-K-K board, so I'll take the free showdown check rather than bloat a pot I'm unlikely to win.

My jacks have showdown value, but betting gets limited value from worse hands and builds the pot against kings or better jacks. Checking keeps the pot controlled and lets me reassess in position on the turn.

With 4c9h I have only a pair of fours on a K-K-J-4 board, so checking is the cheapest way to see the river without bloating the pot.

After two checks, my pair of jacks is likely ahead of much of the small blind's range. A half-pot bet can get calls from weaker pairs and draws while denying free equity to overcards.

I hold two pair, kings and fours, which is strong on this board, and calling 100 into a 300 pot is well priced against a turn bet.

I have only a pair of fours on a board with a king pair and no call is required, so checking keeps the pot small and avoids investing more chips with a weak hand.

My kings-and-jacks two pair has showdown value, but the river completes flush and straight draws. Checking avoids paying off stronger hands when few worse hands are likely to call a bet.
