Hold'em table

87o is too weak to open first in from the button for 100 chips; folding avoids a dominated, low-equity hand out of position postflop if called.

K6 offsuit is a marginal hand, but completing the small blind for 50 more into a 150 pot is cheap and keeps the hand alive heads-up against the big blind.

I have J4 offsuit in the big blind after the small blind completes. Checking to see a free flop in position is the standard and highest EV play.

Holding K-high with no pair against a board of Q-Q-3, I have little showdown value, so I take the free check rather than bloat the pot out of position.

We have Jack high with minimal equity on a paired board in position. Checking behind to see a free turn is standard.

I hold two pair, queens and sixes with a king kicker, so I bet for value into the 200-chip pot while the big blind has shown weakness by checking.

I have Jack-high with no significant showdown value or draws against a turn bet, making an easy fold.

Jack-six suited is a playable hand in a three-way pot, and calling the 100-chip price keeps me in cheaply with good playability postflop.

Getting 5-to-1 immediate pot odds from the small blind against a button limp, K6o has sufficient equity to complete.

A8o is playable but not strong enough to isolate two limpers out of position, so I take the free option and see a flop.

Check bottom pair with an overcard kicker out of position in a three-way limped pot to control the pot size.

Ace-high with no pair or draw on JT6 is too weak to bet into two opponents, and checking is free.

I have two pair, jacks and sixes, on a board where both opponents checked, so betting about two-thirds pot builds the pot for value.

Holding bottom pair on a connected board with another player still to act behind, folding to a 2/3 pot bet is standard.

Ace-high with no pair or draw is too weak to continue against a flop bet, so folding is the best option.

On the button in 3-handed play, Q9o is well within a standard opening range to steal the blinds and realize position.

42s is too weak to continue out of position against a button raise with the big blind still to act.

Tc3c is a weak, disconnected offsuit hand facing a 100-chip raise to 200 from the button, so folding avoids a costly marginal call out of position.

K9o is a standard button open in three-handed; raising to 2.5bb takes the initiative with a playable king-high.

Seven-five offsuit is a weak hand that plays poorly out of position against a button raise, so folding the small blind saves chips.

J9 offsuit does not realize equity well out of position against a 2.5x button open, making folding the standard play.

Queen-four offsuit is a weak hand to play from the button for 100 chips, so folding preserves chips over the long run.

K3o plays poorly out of position postflop against the big blind, making it a standard fold.

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

K3 suited has enough equity heads-up versus the big blind to complete for 50 into a 150 pot; no need to fold or inflate the pot out of position.

I'm in the big blind with no bet to call, and T-J offsuit is a marginal hand that's better to see a free flop with than to bloat the pot out of position.

I have top pair on a dry flop and can bet half pot for thin value and protection against the big blind.

I hold a pair of tens with a jack kicker, which is medium strength on this King-high board, and the 100-chip bet only asks for a small call against a 300-chip pot. Calling keeps me in without risking a raise against a possibly stronger hand.

Turn ace devalues my king pair with a weak kicker, and I can check for free rather than bet into a card that improves many calling ranges.

I hold a pair of tens on a board with an ace and king, which is a medium-strength hand. Checking keeps the pot small and lets me see a river card for free after seat_1 checked the turn.

Two pair is ahead of most one-pair hands, but the paired aces make a bet get called mainly by trips or a king. Checking realizes showdown value without facing a tough raise.

I have aces and tens (two pair) on a paired board, which likely beats a checked-down range, so a small value bet extracts chips from weaker pairs or Ax hands.

I have aces and kings on a paired board and only need to call 250 into 650. That price is too good to fold, and raising would mostly get called by better hands.
