Hold'em table

A4o on the button in a 3-handed game is a standard open; raising 2.5x applies pressure on the blinds and takes initiative with position.

QJo is a reasonable three-bet candidate against a wide button opening range, with blockers to strong broadway hands. Raising to 11 big blinds applies pressure and discourages the big blind from joining while compensating for our positional disadvantage.

3h8h is a weak hand facing significant aggression. Seat 1 raised to 250, seat 2 re-raised to 1100, and I would need to call 1000 more with a hand that has poor equity against likely stronger holdings. Folding preserves chips.

A4o facing a large 3-bet (to 11bb) from the small blind plays poorly out of position-ish and is dominated by most 3-bet ranges; calling 850 more with a weak offsuit ace is unprofitable and 4-betting as a bluff with 100bb stacks is marginal. Fold.

Seven-five offsuit is too weak for a standard button open at 100bb without evidence that the blinds overfold. Folding avoids investing in a hand with poor equity and limited playability.

Queen-six offsuit is a weak hand from the small blind. After the big blind, calling 50 more chips to see a flop is marginal at best, especially since folding preserves chips for stronger hands. Folding is the prudent choice.

King-four offsuit is a weak hand in the big blind. With action to act preflop from the button facing a call to the big blind, folding is the correct play to minimize losses with a hand that has poor equity.

Button folded, heads-up vs BB with A3o from the SB at 100bb; any ace is a standard open-raise here rather than limping and giving a free flop.

Against a small-blind open, 98 offsuit is a reasonable big-blind defense with position postflop. Calling costs 200 into a 400-chip pot, and its connectivity offers enough potential against a typically wide opening range.

Top pair with a weak kicker on a Q-A-9 board heads-up out of position; a half-pot c-bet for value and protection against straight draws and worse pairs is standard after raising preflop.

Bottom pair has enough showdown value to defend against a half-pot continuation bet in a blind-versus-blind pot. Calling in position keeps the opponent's bluffs in and lets me reassess on the turn.

Trips aces with a weak kicker on a board where opponent called the flop; bet for value against Qx, 9x, flush and straight draws while charging draws, keeping sizing moderate given kicker issues.

My aces and nines lose to any ace, queen, or higher pocket pair, and I have very little improvement potential. Against this sizable second barrel, calling would rely too heavily on the opponent bluffing.

6-3 offsuit is a clear fold from the button even in a 3-handed game; it's well below a reasonable opening range and plays poorly postflop.

A5 suited is a strong blind-versus-blind opening hand with an ace blocker and good postflop potential. Raising to 3 big blinds pressures the big blind while building a pot with a hand that plays well.

Jack-nine offsuit is a weak holding, and facing a raise to 300 from the small blind with only 200 to call requires hitting a strong flop to win. Folding preserves chips against a positional disadvantage postflop.

T8 offsuit is a reasonable button open three-handed. Raising to 2.5 big blinds pressures the blinds while retaining positional advantage if called.

J7o is a weak hand facing a raise from the button. Folding preserves my stack and avoids playing a marginal hand out of position in a pot that's already grown to 400 chips.

76s in the big blind facing a 2.5x button open with 150 to call into a 400 pot is a standard defend; suited connectors play well postflop and we're getting good pot odds heads-up.

Pair of sevens plus open-ended straight draw and backdoor spades on a coordinated board that hits my BB calling range; leading builds the pot with strong equity and takes initiative versus a button open.

Middle pair plus an open-ended straight draw has enough equity to continue against this bet. Calling in position preserves weaker hands in the opponent's range and avoids inflating the pot against strong made hands.

Turn gives us trips with an open-ended straight draw on a coordinated board; betting ~2/3 pot for value and protection against overpairs and draws that called the flop.

My pair and open-ended straight draw retain enough equity against a range containing draws and one-pair hands to continue in position. Calling preserves showdown value without inflating the pot against trips or stronger hands.

Trips sevens on a board where the river ace likely improved many of villain's calling hands (Ax, and overpairs still call); bet ~60% pot for value while keeping it manageable against the few full houses/straights.

My eights and sevens are only a bluff-catcher against three substantial bets, and the river ace further weakens their showdown value. Calling requires about 27% equity, which is unlikely against this line without evidence of frequent bluffing.

Q4o is a weak hand in early position (button here facing two opponents). With no fold equity and poor playability, folding is the mathematically sound decision to preserve chips for better spots.

Button folded, so it's SB vs BB heads-up; J5o is a marginal hand but SB open-raising against a single opponent with 100bb is standard and folds out many hands, taking the pot down often. Completing invites BB aggression with no initiative.

KJo is a strong defend against a small-blind opening range, and calling costs 200 to contest a 600-chip pot. Calling preserves weaker hands in the opponent's range and lets us play in position postflop.

I'm the preflop aggressor out of position on an ace-high dry board with bottom pair; a small c-bet (1/3 pot) leverages range advantage, denies equity from overcards, and often takes it down cheaply.

K-high has no pair or immediate draw on this ace-high flop, and pairing a hole card may still leave me behind. With only a weak runner-runner straight possibility, folding is preferable to paying for a speculative float.
