Hold'em table

9h4s is a weak offsuit hand with little playability preflop, and folding avoids investing chips without any equity edge.

79o is too weak to complete or raise out of position against the big blind after the button folds, so I give up the small blind.

87 offsuit is too weak to open from the button into two live blinds; it is easily dominated and does not justify a limp or a steal.

Weak offsuit hand (J6o) heads-up vs big blind after button folded; not worth calling with a poor hand out of position.

Button facing a raise with weak offsuit J9; not worth continuing since it's not just a limp scenario, folding preserves stack.

4-2 offsuit is a very weak hand, and the big blind has already committed 100 chips. With no information about their strength, folding minimizes losses.

I have King-high with a backdoor flush draw, which is decent but not strong enough to raise preflop. Calling keeps the pot small and lets me see a flop without overcommitting.

65o is too weak to continue out of position multiway for even a cheap complete, especially with the big blind still to act. Folding avoids a dominated spot where equity is hard to realize.

I'm in the big blind with no raise to face, so I check with my weak offsuit hand and see a free flop.

I have a pair of jacks with a decent chance of being best hand; betting protects against the flush draw and extracts value from worse hands.

Calling 150 into a 400 pot with top pair on a J-K-8 board is reasonable; I have the K and can improve with a Q or 9 for a straight. Folding would be too weak, and raising risks getting 3-bet by a stronger hand.

My jacks are second pair with a weak kicker on a scary A-K board; checking keeps the pot manageable and lets me reassess based on villain's action.

Board is paired with an Ace on the turn and I hold the Kc, giving me a strong top pair. Checking allows me to control the pot size and potentially induce a bluff from seat_3 on the river.

My hand is only a modest pair of jacks with backdoor flush risk on the river; checking to control pot size seems safer than betting into an unknown range.

The board is paired with an Ace on the river, and my hand is Kc7c, which is likely dominated by seat_3's range given their flop raise. With no money to call and a weak kicker, checking to see a showdown is the highest EV play.

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

Cheap price to see a flop heads-up against BB with Q7o; folding is unnecessary given the small additional cost.

I'm in the big blind with 3c Tc and no raise to call, so checking keeps my optionality and lets me see a flop cheaply. The pot is small and my hand is suited and connected enough to play postflop.

Q7 offsuit missed this dry board completely; checking to control pot size against a player who already checked.

I have top pair with a ten on a 2-T-3 flop, but the board is dry and my opponent checked behind. Checking keeps the pot small and avoids scaring out a bluff while allowing me to control the hand on later streets.

Weak hand with no pair or draw; checking to see a free card and avoid building a pot I likely lose.

The board is paired with 3s and 3d, and my 3c gives me a set. Checking allows me to control the pot size and potentially induce a bluff from the opponent on the river, while also saving chips if they have a stronger hand like a full house.

My Q kicker beats the board's ten kicker, so I have a decent two-pair hand; a modest value bet may get called by weaker kickers after a passive line.

I have a full house (threes full of twos) on a paired board, which is a very strong hand. Calling the small river bet is clearly profitable and avoids risking more chips unnecessarily.

A7 offsuit on the button is a reasonable raising hand heads-up-ish; raise to isolate and take initiative.

I hold 2s9s, a weak hand that is unlikely to improve enough to justify calling a 250-chip raise from the button. Folding preserves my stack against a strong range.

65 offsuit is too weak to continue out of position against a button raise, so folding is the highest-EV option.
