Hold'em table

On the button with K3s I open to 2.5bb to steal the blinds and play in position; the hand is too weak to flat but has enough suited equity to raise.

Jd5c offsuit is a weak hand facing a raise; folding is standard here.

With Jc6c on the button facing a raise to 250 and only a 150 call, the pot odds don't justify continuing with a weak hand. Folding preserves my stack for better opportunities.

J2 offsuit is a weak hand out of position with no blind investment yet; folding is standard here.

Calling the small blind with 4d3d keeps the pot small and preserves my stack while I wait to see the flop; I have no strong made hand yet and a cheap look is the highest-EV play here.

52s is too weak to raise out of position against a completed small blind, and checking is free, so I take the flop.

I have a weak connected hand on a wet board and the pot is small; checking keeps the pot controlled and avoids building a bigger pot with a marginal holding.

5h2h has no pair, no draw, and no showdown value on Th-6s-7c, so checking back the free card is better than bluffing with zero equity.

Board is paired with a 6, and my 4-3 offsuit is weak; checking keeps the pot small and avoids building a bigger pot with a marginal hand.

I have no pair, draw, or showdown value on this paired board, and seat 3 has already checked. Checking keeps the pot small and avoids turning a weak hand into a bluff.

The board is paired with a 6, and my 4-3 offsuit is unlikely to be ahead. Since checking is legal and there's no cost, I'll take the free showdown and minimize risk.

I only play the board pair of sixes, so I chop with air and lose to any pair or straight. A minimum bet is too large to profit if better hands call and chops fold, so I check.

6s 7d is a weak hand with no pair and disconnected suits, and I am out of position on the button facing a raise. Folding preserves my stack for better opportunities.

Pocket nines are well ahead of the big blind's range heads-up after the button folds, so I raise to 400 for value and to build the pot.

Facing a 4x raise from the small blind with Q7 offsuit, a weak hand not worth defending against a strong opening range.

KJo is a strong button open in three-handed play, so I raise to 2.5bb to take the initiative and fold out weaker hands.

ATo is strong enough in a 3-handed pot to 3-bet the button's open and apply pressure, while still keeping the pot manageable.

My hand is weak (Q-5 offsuit) and I'm facing a large overbet raise to 800 from the small blind. The pot odds don't justify continuing with such a dominated hand, so folding minimizes losses.

KJo is ahead of a wide three-handed small-blind 3-bet often enough to continue in position; calling 550 into 1700 keeps the pot manageable without bloating it with a dominated offsuit broadway.

Top pair with strong kicker on a wet board; betting for value and to protect against flush/straight draws.

I have an open-ended straight draw to the nuts on either an ace or an eight, and the 1100 call into 2800 gives acceptable odds in position. Calling keeps the pot manageable and lets me realize equity rather than bloating it against a strong preflop raiser.

I have top pair tens with ace kicker and want to protect against flush/straight draws while extracting value; a sizeable turn bet fits my range and the board's texture.

I have the nut straight (K-Q-J-T-9) on the turn and seat_2 has barreled every street. Raising all-in charges draws and two-pair/sets before a club or pairing river can change the nuts, and the stack-to-pot ratio makes getting it in the highest-EV line.

Facing an all-in raise on the turn on a coordinated, clubby board that hits many straights/flushes/sets, my mere pair of tens with an ace kicker is far too weak to profitably call; the betting pattern strongly suggests a much stronger holding.

T2 offsuit is a weak hand out of position with no equity edge to justify calling from the button in a 3-handed pot.

I have 9-high with no pair or draw, and the small blind has already invested 50 chips. Folding avoids losing more chips with a weak hand.

I have 2c Kd on the button with no prior investment. The small blind opened with a min-raise to 200, and my hand is too weak to continue against a likely range of pairs and suited connectors. Folding preserves my 10000 stack.

Button folded, so this is heads-up versus the big blind. A6o is strong enough to open-raise out of the small blind rather than complete out of position.

Facing a min-ish raise heads-up with K6o and getting decent pot odds (200 to win 500), calling is reasonable against a wide SB opening range.

Top pair on a dry flop heads-up; a small c-bet gets value from worse aces and draws while denying free cards.

King-high with no pair, no draw on an Ace-high board; folding to the flop bet is correct with no equity.
