Hold'em table

T5o is a weak offsuit hand and I am first to act preflop; folding avoids investing chips out of position with poor playability.

Q4o is too weak to continue out of position against the big blind after the button folds, so I give up the small blind rather than inflate a dominated hand.

69 offsuit is too weak to open from the button for a full big blind, so folding preserves chips.

I have a weak offsuit hand (Jh2s) and the small blind has already entered the pot. With no other callers and a big blind of 100, folding minimizes losses on this marginal holding.

4s 3s is a weak speculative hand that needs good position and low cost to justify playing. Facing a 100bb raise with no prior investment, folding preserves my 10000 stack for better spots.

With the button out, K9o is strong enough to raise and attack the big blind rather than just complete. This applies fold equity and takes initiative.

Q5 suited has enough playability in position against a small-blind open, and the pot odds justify a call rather than a fold or a weak three-bet.

King-high has little equity on an A-high board out of position, so checking controls the pot and avoids bloating against the big blind's calling range.

Queen-high with no pair or draw on an ace-high flop. Seat 1 was the preflop raiser and checked, so I take the free card rather than bluff a weak hand.

I have only king-high with no pair and little equity on an ace-high board. Checking controls the pot and avoids bluffing into a range that called preflop and can contain many aces or pairs.

Queen-high with no pair and no real draw has little value or bluff equity against the preflop raiser, so I take the free river.

I have middle pair with a king kicker on a checked-down board; a small bet can get called by worse pairs and fold out missed draws.

Queen-high with no pair or draw loses to any made hand, and a small river stab is not enough reason to call 200 into this pot.

J4o is a weak offsuit hand and calling 100 chips out of position against two players is not profitable; folding avoids unnecessary risk.

Button folded, so I only need 50 more to see a flop heads-up with king-high. K7o is too weak to raise, but folding a hand that already has half a blind invested is unnecessary.

I am in the big blind with no raise to call, so checking is the correct play. My hand is weak and I want to see a cheap flop.

King-high with no pair or draw on an ace-high flop has little showdown value and no strong bluff equity out of position, so I take the free card.

Top pair with Ace kicker on a dry flop; checking keeps the pot small and avoids building a big pot with a weak kicker against a possible set or overpair.

King-high with no pair or meaningful draw on an ace-queen board; checking keeps the pot small rather than bluffing into a possible ace.

The board is paired with an Ace, and I hold the Ah, giving me top pair with a decent kicker. However, the opponent has been passive, and the pot is small. Checking keeps the pot controlled and avoids building a big pot with a marginal hand.

King-high has no showdown value, but a river bluff into a player who has checked and claimed an ace is unlikely to succeed. Checking is free.

The board is paired with an Ace, and my Ace-high is vulnerable to better pairs or two-pair hands. Since the opponent has checked twice on the turn and river, I will check behind to realize my equity without building a bigger pot with a marginal hand.

K7o is a marginal but playable button open in three-handed play, so I raise small rather than limp or fold.

I have Q♠6c, a weak offsuit hand. The button raised to 250 and I'm in the small blind with only a 50bb effective stack. Calling 200 more to see a flop with this hand is a losing play; folding preserves my stack for better spots.

Closing the action preflop with 2.67:1 pot odds and a suited hand; J2s has enough equity versus a button open to call, though I will proceed cautiously postflop.

I have an open-ended straight draw but no made hand, and the board strongly favors the preflop raiser's range. Checking controls the pot and lets me see a turn card without risking a raise.

Top pair with a weak kicker on a very connected K-Q-T board is not strong enough to build the pot; checking back in position controls the pot and realizes equity.

Semi-bluffing the turn with an open-ended straight draw; opponent checked back the flop and may fold to pressure.

I have top pair on a coordinated board and the turn bet is only about half pot, so folding is too tight and raising with a weak kicker is unnecessary. Calling keeps the pot manageable and realizes my showdown value.

My pair of jacks is weak on this coordinated board, and checking avoids putting more chips in with a marginal hand while allowing me to fold to a bet.

I only have a weak pair of kings on a four-straight board, so betting gets called by better and folds out worse. Checking back is the highest-EV line.

3s 6c is a very weak hand with no playability. I'm out of position on the button and facing a 100 chip call, so folding is the correct decision.

K2o has enough equity to complete against a random big blind, and calling keeps the pot small while out of position. Raising would bloat the pot with a weak offsuit hand.

5-9 offsuit is too weak to raise, and checking is free as the big blind after the small blind limps.

I have a marginal bottom pair on a coordinated board and am out of position; checking keeps the pot small and lets me evaluate the turn before committing more chips.

Nine-five offsuit has no pair and no draw on As-2s-Js, so checking behind after the small blind checks is the highest-EV line.

I have a weak pair of twos with a king kicker on a coordinated board. Checking controls the pot and avoids getting raised off my marginal showdown value.

I have nine-high with no draw on a three-spade board, so there is no value in betting. Checking keeps the pot small and realizes a free river.

Weak pair on a four-spade board; checking to realize showdown value and avoid bloating the pot against a possible flush.

I only have a pair of nines on a four-spade board, so a bet is unlikely to get called by worse and often loses to a flush or a better pair. Checking realizes the free showdown.
