Hold'em table

J8o is a playable button open in three-handed poker with position, so I raise small to steal and can fold to a reraise.

Q3 offsuit in the small blind facing a 2.5x button open is a clear fold; it plays poorly out of position and dominated.

Pocket fives play well in position heads-up; calling 150 keeps the pot small and lets me set-mine or play postflop with a real hand against seat_1's 2.5x raise.

I hold 55 on an AK2 board with no bet to call; checking keeps the pot small and lets me see a cheap turn with a low pair.

J8o has no pair, no club draw, and little equity on AK2. Checking back is free and avoids spewing a bluff with a hand that cannot continue if called.

I hold 55 with no pair on a scary board; with no bet to call, checking is free and I can fold to pressure.

Jh8d has no pair, no draw, and no showdown value on an ace-king board. Checking behind avoids betting air into a range that can easily have a pair.

The board pairs aces, giving me trips with my 55; a small river value bet targets seat_1's preflop-raising range, and I can still call a raise.

Jh8d does not improve the paired ace board, so I only chop against a hand that also cannot beat the board. A river value bet makes that too unlikely to call.

K2o on the button in a 3-handed game is a marginal but playable open; raising to 2.5bb takes the initiative and often wins the blinds, and we have position postflop.

QTo is a marginal hand facing a 2.5x raise out of position with a player still behind; folding is the profitable play.

Nine-five offsuit is too weak to continue against a button open after the small blind folds, so folding saves the extra 150 chips.

53s offsuit is the worst hand in 3-max; folding on the button is standard.

Button folded, so this is heads-up versus the big blind with KJo. A standard raise to 300 builds the pot and applies pressure before the flop.

Button folded, SB raised to 3bb; I'm in the BB with 65o getting 2:1 (200 to win 400) and position postflop. Heads-up blind vs blind, this is a marginal but reasonable defend given price and position.

The 789 flop is connected and favors the big blind's calling range. With only overcards and a gutshot, checking is better than bluffing into it.

Flopped a straight (5-6-7-8-9) on a wet, two-heart board; betting ~75% pot for value and protection against flush draws and higher straight draws after villain checked.

KJo has only a gutshot and overcards on a connected 789 board, and calling 450 out of position is not justified against a flop lead.

Q5 offsuit is too weak and dominated to open from the button for a full big blind; folding preserves chips.

Button folded; blind-vs-blind with a suited ten I take the initiative and attempt to steal the blinds, with playable equity if called.

J5 offsuit is a weak hand facing a 3bb raise from the small blind; folding is clearly best.

Q8o on the button in a 3-handed game is a standard open; raising to 2.5bb takes initiative against the blinds.

J7 offsuit is too weak to call 2.5x out of position against a raiser; folding is clearly best.

26 suited is too weak to defend the big blind out of position against a button open; folding saves the extra 150.

A7o on the button in 3-handed is worth a standard open-raise to build the pot and apply pressure.

Pocket jacks are well ahead of a button open, so I 3-bet to about 10bb to build the pot and deny equity while still leaving room to fold to a large 4-bet.

A6 offsuit facing a 3-bet to 1000 with the original raiser still to act behind me is an easy fold; the hand is dominated by most 3-bet ranges and plays poorly out of position.

A7s is dominated against a 4x 3-bet range; folding and saving 700 chips is clearly best.
