Hold'em table

A4 offsuit is a reasonable button open three-handed, with an ace blocker and positional advantage. Raising to 2.5 big blinds pressures the blinds without risking too much.

QJo in the SB facing a 2.5x button open is a reasonable defend; 3-betting is thin and folding gives up too much equity versus a wide button range, so I call and play postflop.

3h8h is a weak hand with minimal potential. Folding saves chips against two opponents who have already committed significant bets preflop, reducing variance and preserving stack for stronger spots.

Top pair with a queen kicker on a dry-ish flop out of position vs the preflop raiser; checking to let the aggressor c-bet and then call or raise is better than leading into them.

My pair has showdown value but is unlikely to get called by many worse hands. Checking keeps the pot manageable and lets me reassess in position on the turn.

Second pair with Q kicker on a three-diamond board with a K overcard is a marginal hand; out of position I prefer to check and keep the pot controlled, calling a reasonable bet rather than bloating it.

My pair has some showdown value, but betting would mostly fold worse hands and get called by better pairs or diamond draws. Checking preserves the pot and avoids building it with a weak hand on a three-diamond board.

Middle pair of jacks on an A-K-high three-flush board is too thin to value bet; worse hands mostly fold and better hands call. Check and evaluate if the button bets.

Rivered two pair is strong enough to value bet after three checks from the opponent. A modest sizing can draw calls from weaker aces and some king- or jack-pair hands.

Second pair with a queen kicker facing a half-pot river bet after the button checked back flop and turn; I need ~27% equity and the checked-back range contains enough missed hands and thin stabs to justify a bluff-catch.

7-5 offsuit on the button in a 3-handed game is below a standard opening range; folding avoids playing a weak, dominated hand out of position postflop against two live opponents.

Q6o is a weak hand in a 3-way pot where I'm out of position as small blind. With only 50 chips to call against a 100-chip big blind raise and the button already folded, folding is the mathematically sound play to preserve chips.

K4o is a weak hand out of position on the button. With 100 chips to call into a 150-chip pot against two opponents, folding preserves chips for stronger spots where position and hand strength align better.

With the button folded, A3 offsuit is a reasonable blind-versus-blind open. Raising to 3 big blinds applies pressure and gives us a chance to win the pot immediately.

Button folded, SB raised to 3bb; I have 98o in the BB getting 400:200 pot odds with position postflop. Calling with a playable connected hand is standard against a blind-vs-blind raise.

Top pair with a weak kicker has showdown value but is vulnerable to better aces. Checking controls the pot and keeps weaker hands and potential bluffs in the opponent’s range.

Bottom pair on an A-Q-9 board with an open-ended-ish gutshot (T,J needed); betting for value is thin and I'd often get check-raised or called by better, so checking back to realize equity and see a cheap turn is best.

Bet for value with trip aces after the flop checked through. This sizing can get calls from queens and straight or heart draws while charging them to see the river.

I hold nines up (pair of 9s with aces on board). Villain checked the flop then bet the turn, which is often a probe or bluff; I'm getting ~2.5:1 and my hand beats missed draws and Qx-less bluffs, so calling as a bluff-catcher is correct while raising folds out worse.

Trip aces have solid showdown value, but this river completes both heart flushes and JT straights. Checking avoids a thin value bet that is unlikely to get called often by worse and preserves the option to bluff-catch.

Board AAKQ with three hearts; my nines play as aces up with a 9 kicker, which loses to any A, K, Q, flush, or straight. No worse hand calls a bet, so I take the free showdown.

63 offsuit is too weak to open profitably on the button against two blinds without evidence they overfold. Folding avoids investing in a hand with poor equity and playability.

Button folded; A5 suited is a clear raise from the small blind heads-up versus the big blind. Standard 3x open to take initiative.

Jack-nine offsuit is a weak hand that doesn't warrant calling a 3BB raise from the small blind in a 3-handed game. Folding is the prudent play to preserve chips against an aggressive raise.

T8o on the button in a 3-handed game, first to act with 100bb deep; a standard open to 2.5bb is profitable with position against the blinds.

J7o is a weak hand that doesn't warrant investing further against a 2.5x raise from the button. With only 50 chips already committed as the small blind, folding preserves chips for better opportunities.

Suited connectors are a profitable big-blind defense against a button open at this size. Calling costs 150 into a 400-chip pot and preserves the hand’s straight and flush potential at 100-big-blind effective stacks.

Bottom pair with an open-ended straight draw and a backdoor flush draw has good equity, but checking keeps the pot controlled out of position. I can respond to the preflop raiser's bet based on its size.

Top pair with an open-ended straight draw on a 7-8-9 board; betting for value and protection after BB checks, ~2/3 pot sizing.

Bottom pair plus an open-ended straight draw and backdoor flush potential provides enough equity to call at 28% pot odds. Calling preserves weaker hands and avoids inflating the pot against a stronger continuing range.

Turning trips gives us a strong value hand with additional straight outs. Leading gets value from overpairs and draws while preventing those hands from checking behind for a free river.

Two pair (eights and sevens) with an open-ended straight draw on a paired board; the turn donk-lead is polarized but I beat 9x, overpairs, and bluffs and have 8-9 outs even against trips, so calling at ~28% pot odds is clearly correct while raising risks getting stacked by 7x or straights.

Trip sevens can extract value from Ax, pocket pairs, and other bluff-catchers that called the turn. Betting about 42% of the pot encourages those weaker hands to call without overcommitting against straights or stronger trips.

We hold two pair (eights and sevens) and get about 23% pot odds on a smallish river bet; opponent's lead range includes 9x, 8x and bluffs often enough to call, while raising only gets called by hands that beat us.

Q4o is a weak hand from the button in early position. Folding preserves chips against two opponents who have already committed, avoiding a marginal situation where we'd be out of position postflop.

Completing the small blind costs only 50 into a 150-chip pot. J5 offsuit is marginal out of position, but has enough equity against the big blind’s unrestricted range to justify a limp.

KJo is well ahead of a small-blind limping range heads-up; raising for value and to take initiative with position disadvantage mitigated by strong hand.

J5 offsuit is too weak to defend against this raise out of position. Folding avoids investing more with poor equity realization and frequent domination.
