Hold'em table

A♥9♠ is a strong button opening hand three-handed; raising to 2.5bb applies pressure and builds value.

KQo is strong enough to 3-bet against a button open in a 3-handed game; raising to 800 applies pressure and takes initiative.

Jack-Ten offsuit is a marginal hand facing aggressive action. Seat 1 raised to 250, seat 2 re-raised to 800, and I need to call 700 more. This is a 3-way pot with strong action from early positions, and my hand is unlikely ahead. Folding preserves chips for better spots.

Ah9s is strong enough to continue in position versus the small blind's 3-bet, while avoiding unnecessary variance from a 4-bet against an unknown range.

I 3-bet preflop and the low, semi-wet board favors a continuation bet to fold out A-high and weaker hands while denying equity to draws. If raised, I can easily fold.

I have the nut-heart flush draw plus an overcard in a 3-bet pot. Calling keeps weaker hands and bluffs in while retaining strong equity.

Semi-bluffing with a flush draw plus two overcards; betting the turn applies pressure and builds the pot for when I improve.

I have the nut-heart draw with additional potential ace outs, and the price is reasonable given direct equity plus implied value when a heart arrives. Calling preserves those outs without overcommitting into a strong multi-street line.

I have the nut flush with the ace of hearts on a three-heart board. Shoving maximizes value against lower flushes and strong ace holdings after villain's river check.

My K-high has no pair, no flush, and no straight on a coordinated board, and the all-in river shove represents a very strong range after calling flop and turn bets. Calling 6300 would require over 31% equity, which this hand almost never has against that line.

Three-handed on the button with a suited queen; opening to 2.5bb applies pressure and can steal blinds, while the hand has enough equity to continue if called.

King-three offsuit is a weak hand that doesn't merit calling a 2.5x raise preflop from the button. Folding preserves chips when equity is poor.

A5 suited is a strong blind-versus-button defending hand and plays well as a polarized 3-bet. Raising applies pressure while retaining useful blockers and wheel potential.

Q2s is too weak to continue against a big blind 3-bet, especially with the small blind already folded and only 600 more to call offering poor implied odds.

7-4 offsuit is one of the weakest hands in poker. Folding is the correct decision from the button against standard opposition, as the hand has poor win equity and will likely be dominated if called. The cost of playing dominates the infrequent wins.

KJ offsuit is a strong heads-up blind-versus-button-fold hand and benefits from taking initiative. I raise to 3bb to apply pressure and build a pot with a range advantage.

With 2h4s out of position and facing a raise, this is a clear fold; the hand has very poor equity and no profitable call or bluff-raise is warranted.

4-3 offsuit is too weak to open from the button in this short-handed configuration.

Button folded, so I only need 50 more to see a flop heads-up against the big blind with a suited hand. T2s is weak, but the pot odds are good enough to complete rather than fold or bloat the pot with a marginal raise.

I'm in the big blind with Q8o, a marginal hand. Since seat_1 folded and seat_2 only called my big blind rather than raising, checking allows me to see the flop cheaply in position against one opponent with a relatively weak preflop action from them.

I have no club on a monotone flop and only ten-high, so checking keeps the pot small and avoids building a pot out of position with a weak hand.

I hold Q8 (pair of Queens with 8 kicker) on a Q84c flop with two clubs. With a 3-handed game and only one opponent still in, checking is prudent to control pot size and see the turn while maintaining position; my hand is moderately strong but vulnerable to flush draws.

With T-high and no club on a monotone board, I have little showdown value and no need to build a pot out of position. Checking keeps the pot small and lets me evaluate the river.

I have a pair of Queens with an 8 kicker on a board with three clubs. With two opponents who have checked throughout, a check here keeps the hand in play cheaply while I see the river. My hand is moderately strong but vulnerable, so I avoid inflating the pot unnecessarily.

My hand has no pair and only T-high, so betting would risk chips with little chance of folding a better hand. Checking keeps the pot small and gives a chance to win if opponent also missed.

On the river with a pair of Eights and pair of Queens, I have a modest two-pair hand. Seat 2 has checked throughout all streets, indicating weakness, so checking is the optimal play to avoid inflating the pot against likely weaker holdings while securing a showdown.

KQo on the button in a 3-handed game is strong enough to raise for value and take initiative. A 3bb raise applies pressure to the blinds while keeping the pot manageable with a non-premium broadway hand.

K7o is a weak hand from the small blind. Facing a 3x raise from the button with a small blind of 50, folding preserves chips rather than committing more to a marginal holding against an aggressive opponent.

Defend the big blind against the button min-raise with QTo; it has adequate equity heads-up and realizes reasonably well.

Check with queen-high and a diamond draw on this paired board, preserving flexibility versus the preflop raiser.

I will continuation-bet with two overcards and position on a low paired board; this can take down the pot immediately and I can shut down if raised.

Call with a diamond draw, two overcards, and favorable pot odds versus a likely frequent continuation bet.

Villain's turn check after betting the flop can contain many missed overcards and marginal hands. A modest bluff applies pressure to that portion of their range while risking less than a large bet.

A5o is a weak holding in a 3-player game, especially out of position on the button facing a big blind raise. Folding preserves chips for better opportunities.

8-9 suitedness is absent, but 9-8 offsuit has sufficient equity heads-up to complete from the small blind at this price.

With a weak suited gapper in the big blind and no need to call, checking keeps the pot small and sees a free flop.

This weak 9-high hand has no made value and only tenuous backdoor prospects on this coordinated board, so checking preserves the pot.

With 8-high and no strong draw on a King-high flop, I prefer to check behind and see a free turn rather than bluff into an opponent who may have connected.

The ace is a favorable scare card after the flop checks through, and a small turn stab can fold out many missed hands cheaply. I retain a gutshot to the queen if called.

With 8-high and no pair or draw on an ace-high board, calling 100 into 300 is not profitable, so I fold.
