Hold'em table

JJ is a premium hand on the button in a 3-handed game, so I raise for value to 3x the big blind.

3d2d from the small blind facing a 3x open with the big blind still to act is a clear fold; it plays poorly out of position and lacks the equity to call or 3-bet profitably.

9-3 offsuit is very weak against a button raise to 300; calling 200 from the big blind would be unprofitable.

8-4 offsuit is a weak hand even on the button in a 3-handed game; folding avoids playing a dominated hand out of position postflop against two blinds.

Heads-up in the small blind after the button folded, T8o is ahead of a wide big-blind range and plays well as a raise to apply pressure and build value.

K3o in the big blind against a small-blind raise to 250 gets good pot odds (150 to win 350, about 30% equity needed), and heads-up the small blind's range is wide. K-high has enough equity and a reasonable post-flop playability to call, and a 3-bet bluff is unnecessary.

Second pair as preflop raiser on a rainbow K-T-7 board benefits from a small bet for protection and thin value against 7x, draws, and worse pairs, while keeping the pot manageable if called by a king.

Top pair with a king on a K-T-7 board is strong enough to continue against a small continuation bet from the small blind. Calling keeps weaker hands in and avoids bloating the pot with a mediocre kicker.

Middle pair of tens with weak kicker has showdown value but loses to kings and better tens; checking controls the pot and avoids being called only by better hands.

Top pair with a weak kicker, in position after the opponent checked the turn. A half-pot bet gets value from worse Kx and pairs and denies equity to draws.

Middle pair of tens with a weak eight kicker is out of position facing a half-pot turn bet after calling the flop; likely behind king pairs and better tens with few outs, and river play will be difficult.

T8o is a playable button open in 3-handed play; raising applies pressure to the blinds and leverages position rather than limping.

J9 offsuit out of position against a button raise, with the big blind still to act behind me, is a marginal hand that plays poorly. Calling 200 more is not worth it, so I fold.

7h4h suited in the BB facing a 2.5x button open; pot odds are 150 to win 400 (~27%), and suited connected-ish hands realize equity reasonably well, so a defend is fine at these stacks.

I have 7h4h with no pair, no draw on an Ace-high board that favors the preflop raiser; checking to see if I can realize equity cheaply or fold to a bet.

With two pair tens and eights on an ace-high board, betting in position gets value from ace pairs and draws while protecting against overcards and straight draws.

7h4h completely whiffed on T-A-8 rainbow with no draw; facing a 400 bet into 550 there's no equity to continue.

K3 offsuit is a weak hand in a 3-handed game. Even on the button, calling 100 out of position against two live blinds is marginal and unprofitable, so I fold.

Button folded, so it's SB vs BB with 6c4s; getting 3:1 to complete with a suited-less but playable connector-ish hand in position-disadvantaged spot, a limp is cheap and keeps the pot small.

With 2c3s in the big blind and only a small-blind limp, checking is free and avoids building a pot with a very weak hand.

I have 6-4 offsuit with no pair and only a backdoor straight draw on an A-Q-7 board; checking keeps the pot small and lets me realize equity or bluff later if the big blind shows weakness.

With 2-3 on an A-Q-7 board I have no pair or meaningful draw, so taking the free card is better than bluffing into a checked pot with almost no equity.

6c4s has only a gutshot (needs a 3 or 5) on A-Q-7-2 board; pot is tiny and heads-up after both checked the flop, so take a free card rather than bluff into a possible ace.

With bottom pair on an ace-queen board, checking keeps the pot small and preserves showdown value; betting would only fold hands I beat and get called by better.

Six-high has zero showdown value, and villain has shown weakness by checking flop and turn; a 3/4-pot bet only needs to fold out ~43% of a range full of missed hands to profit.

Opponent checked flop and turn in a limped pot, discounting Ace or Queen value hands, so the river bet is bluff-heavy. My two pair beats all unpaired bluffs and I need only about 30% equity at these pot odds.

86o on the button in a 3-handed game is marginal; folding avoids playing a weak offsuit hand out of position against unknown opponents. A raise is reasonable too, but a disciplined fold keeps variance low.

J8o is playable heads-up in the small blind for just 50 more; limping keeps the pot small while out of position postflop.

7-2 offsuit is the worst starting hand, so I take the free flop from the big blind instead of raising.

J-high with only weak backdoor draws on T-6-5; checking heads-up keeps pot small and realizes equity for free versus the big blind's wide checked range.

I have 7-2 on a 6-5-T board, which is an open-ended straight draw needing a 4 or 8. Seat 3 checked as the small blind, so a small bet of 100 into the 200 pot can take the pot now and still leaves me outs if called.

J-high with only one overcard and a backdoor straight draw has insufficient equity out of position against the big blind's flop bet, even at a small size.

Suited ace on the button in a 3-handed game is well ahead of a wide defending range, so I raise for value and initiative rather than limping.

J3 offsuit is a weak hand out of position against a button raise with the big blind still to act, so folding is best.

KTo in the big blind facing a 2.5x button open with 100bb effective is a standard defend; we get a good price (150 into 400) and close the action, while 3-betting KTo out of position is marginal.

K-high with a gutshot (J) on a Q-high two-club board, out of position vs the preflop raiser; checking to the aggressor is standard and lets me evaluate a continuation bet.

Semi-bluff with ace-high, an overcard and backdoor nut flush draw; a small c-bet can fold many BB hands that missed this Q-high board.

King-high with only backdoor straight equity on a Q-8-2 two-club board facing a 55% pot c-bet; calling 26% pot odds with little direct outs and poor turn playability is unprofitable, so fold.
