Hold'em table

Pocket jacks are a strong hand in 3-handed play on the button, so I raise to 3bb for value and to build the pot against two blinds.

3d2d from the small blind facing a 3x button open is a clear fold; it plays poorly out of position with the big blind still to act.

9-3 offsuit is too weak to defend the big blind against a button 3x raise out of position; calling would be unprofitable postflop.

8-4 offsuit on the button is well below a reasonable opening range in a 3-handed game; folding avoids playing a weak hand out of position postflop against two blinds.

T8o is ahead of a big blind's wide range after the button folded; raising applies steal pressure while retaining decent equity when called.

K3 offsuit is a marginal hand, but heads-up against a small blind raise to 3bb I get 2:1 pot odds (200 to win 500) and a K-high hand has enough equity to call. A 3-bet bluff with this hand is not attractive.}

Middle pair of tens on a K-T-7 board benefits from a half-pot bet for value and protection against overcards and straight draws, while keeping the pot manageable heads-up.

Top pair with a king on a K-T-7 board is strong enough to continue. The opponent's 300 bet into a 600 pot is a small continuation bet, so calling is the best price and keeps weaker hands in.

Second pair with weak kicker is marginal after opponent called preflop and flop; checking controls the pot and avoids being raised or called only by better Kings and Tens.

Top pair with a king on a dry board; seat_3 checked the turn after betting the flop, so I bet about 58% of the pot for value and to deny equity to draws and weaker pairs.

Out of position with second pair and weak kicker facing a 700 turn bet after flop call; opponent's value range of Kx and better Tx dominates and river play will be difficult, giving insufficient equity for the price.

On the button in a 3-handed game, T8o has enough playability and position to open rather than fold, and raising gives fold equity against the blinds.

J9o from the small blind facing a button open to 250 with the big blind still to act is a marginal hand that plays poorly out of position in a 3-handed pot. Folding is a reasonable, low-variance choice.

Facing a 2.5x button open with 150 to call into a 400 pot (getting ~2.7:1), 7h4h suited connector-ish hand has enough playability and equity to defend from the big blind heads-up in position-disadvantaged but closed action.

7h4h on Th Ad 8s flop gives me nothing but a backdoor flush draw and gutshot-ish nothing; out of position versus the preflop raiser, checking to the aggressor and folding to a bet is the standard line.

Two pair tens and eights beats any single Ace pair and most BB calling hands; bet for value and protection against overcards and draws.

7h4h on Th Ad 8s has no pair, no draw (only backdoor flush/straight), facing a 400 bet into 550; folding is clearly correct.

K3 offsuit on the button is a weak hand; with two players left to act behind and a dominated king, folding is a marginal but safe choice rather than paying 100 into a 150 pot out of position postflop vs. blinds. ::: Actually calling is close, but fold avoids dominated spots. ::: ok

Button folded, so it's SB vs BB heads-up; 64o is a reasonable open-raise from the small blind against a single opponent at 100bb with fold equity and playability, rather than limping or folding out of position.

2c3s is a very weak offsuit hand facing a raise from the small blind; calling 200 more has negative expected value.

86o on the button in a 3-handed game, first to act with 100bb deep; a standard open-raise to 2.5bb steals blinds and plays well in position, which is better than limping or folding this playable but marginal hand.

J8 offsuit is too weak to call a button raise out of position with the big blind still to act, and it is not a good 3-bet bluff candidate.

7-2 offsuit is the worst starting hand, and calling 150 more out of position against a button raise isn't profitable; folding loses only the 100 big blind already posted.

Suited ace on the button in a 3-handed game is a strong open; raising to 2.5bb pressures the blinds and builds value with position.

J3 offsuit is a weak hand out of position in the small blind, facing a button raise to 250 with the big blind still to act. Calling 200 more is not worth it.

KTo in the big blind facing a 2.5x button open with SB folded; getting 400:150 pot odds and closing action, calling is standard with a hand too strong to fold but not strong enough to 3-bet for value.

K-high with a backdoor/gutshot (J needed) on Qc-8c-2d; out of position against the preflop raiser, checking to the aggressor is standard and keeps the pot small.

As the preflop raiser in position I have a range advantage on this Q-high board. A small c-bet with Ace-high and backdoor spades pressures the big blind's wide checked range and can fold many weaker hands.

Facing a small ~1/3 pot c-bet from a wide button open range, KT with a king overcard and backdoor straight draws has enough equity and pot odds (~21%) to float; folding to such a small bet would overfold our BB defending range.

K-high with a gutshot (J for a straight) on Q-high board; out of position against the preflop raiser who bet the flop. Checking keeps the pot small and lets me see what the aggressor does; I can call a reasonable bet with my overcard and gutshot equity or fold to a large one.

Ace-high has some showdown value against missed club and straight draws, and with no meaningful draw or blocker a second barrel risks being called by Qx/8x while drawing nearly dead.

King-high has no showdown value after the straight draw missed; opponent checked back the turn showing weakness, and the river completed a flush and brought a four-to-straight texture, so a ~2/3 pot bluff only needs ~40% folds to be profitable.

Ace-high with no pair or draw on a three-club, connected river; opponent's 650 bet into 950 after calling flop is value-heavy and I lack the ~29% equity needed to call.
