Hold'em table

78o is playable as a button open in three-handed poker with position. A 2.5bb raise builds the pot while keeping the hand flexible.

5-T offsuit is weak against a raise with two players left to act behind; folding preserves chips.

I have a pocket pair of threes and the action is heads-up after seat_2 folded. Calling 150 to see a flop is a reasonable play with a small pair, keeping my stack intact while avoiding a raise that could isolate me further.

I have a pocket pair of threes and the board shows a Ten, Four, and Ace. Checking allows me to control the pot size and potentially induce a bluff from the button, who raised preflop.

I have 78 offsuit with no pair, draw, or backdoor equity on A-T-4. Checking is free and better than bluffing into a caller who can have Ax or a pair.

The board is paired and contains broadway cards, so my pocket threes are vulnerable to overcards and sets. Checking keeps the pot small and avoids building a big pot with a marginal hand.

78 offsuit has no pair, no draw, and no relevant blockers on A-K-T-4, so a turn bluff is poorly placed against a preflop caller. Checking keeps the pot small and avoids investing more with a hand that cannot win if called.

The board is paired with an Ace and King, and my pocket threes are unlikely to be ahead. Checking allows me to control the pot and potentially induce a bluff or see a cheap showdown.

Seven-eight offsuit does not pair or improve this ace-king-high board, so a bet has no value and a bluff is unlikely to fold the pairs in a preflop caller's check-down range. Checking realizes a free showdown.

TJ offsuit on the button is a reasonable steal/value raise against two blinds; sizing to 3x builds pot with positional advantage.

I have 6d 9c, a weak offsuit hand. The raiser on the button opened to 300, and calling 250 more with this hand is a negative expected value play. Folding preserves my stack.

K5 offsuit is too weak and disconnected to defend the big blind against a button open, so folding is the highest-EV line.

I have 5s6h on the button with no prior investment. The pot odds from calling 100 into 150 are marginal, and my hand plays poorly out of position postflop, so folding is the most disciplined choice.

Button folded, so this is heads-up versus the big blind with A7o. A small raise takes the initiative and applies pressure rather than limping.

K2 offsuit facing a raise from the small blind with only one opponent left; not worth defending.

Q8s is a playable suited queen on the button in three-handed, so I open to 3bb rather than limp or fold.

J9 suited is a reasonable speculative hand to see a flop at a decent price, and 3x isolation raises from the button are often light.

My hand is weak (2d Ts) and I'm out of position facing a raise and a call. Folding preserves my stack for better opportunities.

I have no pair and no strong draw on an A-K-3 board; checking to control pot size and see what the raiser does.

Queen-high with no pair or draw on an ace-king board has little equity if called, and checking is free, so I take the free card rather than inflate the pot.

Only a weak middle pair (9s) with A-K on board; better to keep the pot small and check for pot control given no clear value.

Queen-high with no pair or draw has little showdown value, but the pot is small and seat 2 has checked twice, so checking keeps the hand cheap rather than bluffing into a dry board.

I only have third pair (nines) with a weak kicker; no reason to bet into a likely stronger holding after two checked streets, so I'll check and take a cheap showdown.

Queen-high has no pair and little fold equity against a preflop caller who checked down; checking realizes the occasional win against air without bloating the pot.

Three-handed button play with wide opening range; Q7o has enough equity to raise for fold equity and positional advantage.

I have Q7o on the button with a 250 to call facing a 300 raise; the pot odds are poor and my hand lacks the equity to continue profitably.

Nine-five offsuit is too weak to continue out of position against a button open after the small blind folds. Folding saves the extra 200 chips.

I have King-high with a backdoor flush draw, which is marginal for a raise. Calling 100 chips keeps me in the pot without overcommitting with a weak hand.

Q8 suited is playable enough to complete the small blind for 50 into a limped pot, without committing more with a marginal hand against two opponents.

With two limpers and a suited ace in the big blind, a modest raise builds the pot and can isolate weaker hands while retaining good equity.

K5o is weak preflop and I'm out of position facing a raise to 400 from the button; folding preserves my stack for better spots.

Q8s is too weak to continue out of position against the big blind's isolation raise, with significant domination risk and poor postflop playability.
