Hold'em table

Pocket aces on the button; open to a standard 2.5x to build the pot while keeping blinds in range to call with worse hands.

Holding 63 offsuit in the small blind facing a button open is an easy standard fold.

JTo is a standard big-blind defend against a button open to 2.5bb. Calling costs 150 to contest a final pot of 550, and the hand has sufficient equity and straight potential against a typical button range.

With two overcards and a gutshot but no club, checking preserves our equity without building a pot out of position. We can reassess against the preflop raiser's bet size.

Overpair on a wet, connected flop (6-9-7 with two clubs); bet for value and protection against draws after BB checks. Roughly 2/3 pot sizing.

Two overcards and a gutshot provide enough equity against a button continuation-bet range to continue at 28% pot odds. Calling preserves that equity without inflating the pot with a relatively weak draw.

Top pair with a gutshot has solid showdown value, but this coordinated board makes betting into the preflop aggressor unattractive. Checking keeps weaker hands and bluffs in their range without unnecessarily inflating the pot.

Overpair on a wet board; bet for value and protection against flush draws, pairs, and straight draws that called the flop, while keeping sizing manageable if check-raised.

Top pair with a jack kicker and a gutshot is strong enough to continue against this turn bet, which requires about 28% equity. Calling keeps bluffs and draws in the opponent's range without inflating the pot against stronger made hands.

Top pair has showdown value, but the river completes the club draw on an already straight-heavy board. Checking avoids a thin value bet that would mostly get action from stronger hands and preserves the option to evaluate an opponent bet.

River completes the club flush and any 8 makes a straight on 6-9-7-T-4; opponent check-called two streets with a range heavy in draws and pairs that now beat or fold to a bet. One pair of aces is a showdown-value hand here, so checking back avoids being check-raised and realizes equity.

73 offsuit is too weak to open from the button even in 3-handed play.

Completing the small blind costs only 50 into a 150-chip pot. With a suited hand against one opponent, this is a reasonable low-cost entry without inflating the pot out of position.

QJo in the big blind against a small-blind limp heads-up is well ahead of a typical limping range; raising for value and to take the pot down or play in position postflop with initiative is better than checking.

Calling requires 33% equity realization, and 8♦4♦ plays poorly out of position against a raising range. Its weak connectivity and domination risk make folding preferable.

T3 offsuit is too weak for a standard button open at 100 big blinds, with poor connectivity and limited postflop playability. Without evidence that the blinds overfold, folding is preferable to opening or limping.

Button folded, so I'm heads-up in the small blind vs the big blind with J8o, a hand well above the raising threshold in a blind-vs-blind spot; a 3x open takes the initiative and often wins the pot outright.

Q6o is too weak to defend against a 3x open from the small blind, so folding is standard.

AQo on the button in a 3-handed game is a strong hand; open-raise to 2.5bb to build the pot and take initiative against the blinds.

76o is too weak to defend out of position against a button open and with the big blind still to act.

Q7 suited is a profitable big-blind defense against a button open to 2.5bb, needing only 27.3% equity on the call. Its suitedness provides reasonable playability, while calling avoids inflating the pot out of position.

Middle pair with a queen kicker and a backdoor flush draw has useful showdown value. Checking to the preflop raiser keeps weaker hands in and avoids building a pot out of position with a marginal hand.

Standard small c-bet with two overcards on a dry 8-2-7 board after BB checks; takes down the pot often and keeps equity when called.

Middle pair with a queen kicker and a backdoor flush draw comfortably merits a call against this small continuation bet. Calling preserves the opponent's bluffs without inflating the pot against stronger hands.

The ace favors the preflop raiser's range, and our pair of sevens has limited showdown value. Checking keeps the pot controlled and avoids betting into stronger hands while folding out many weaker ones.

Turned top pair with a good kicker on a board where villain called a flop c-bet (likely 8x, 7x, draws, or pocket pairs); betting ~60% pot for value and protection against straight draws like 9T/65 is clearly best.

Third pair with no meaningful draw is a weak bluff-catcher against this second barrel, especially on an ace that favors the preflop raiser. Calling out of position risks further river pressure with few reliable improvement cards.

6h 3s is far too weak to open raise or play even from the button in a 3-handed game.

T9 offsuit is strong enough to complete blind-versus-blind at 3-to-1 pot odds. Limping keeps the pot manageable out of position while retaining useful straight and pair potential.

Button folded and SB limped; T3 suited is a marginal hand that plays fine seeing a free flop in position-less BB spot. Raising has some merit against a limper, but checking keeps the pot small with a weak hand.

T9 has no pair or immediate draw on this ace-high flop, only backdoor straight possibilities. Checking avoids investing with weak equity out of position.

Heads-up limped pot where SB checked to me on a dry A-K-8 board; a small stab with position-like initiative often takes it down since SB's limp-check range rarely connects, and my T3 has no showdown value.

Ten-high has only backdoor straight potential and no flush draw on this ace-king-high flop. Facing a half-pot bet out of position, there is insufficient equity or playability to continue profitably.

On the button in a three-handed pot, 5♣3♣ is a reasonable light open with position and suited straight potential. A small raise pressures the blinds while keeping the investment modest.

9-4 offsuit is a weak hand from the small blind facing a button raise with the big blind still to act; folding is clearly correct.

K6o is slightly too weak to defend out of position against a button open, making fold standard.
