Hold'em table

With a small pair on the button in a three-handed pot, raising is profitable and gives me initiative; 250 is a sensible open size.

Q9 offsuit is too weak to play out of position from the small blind against a button raise, especially with the big blind still to act.

T8o offsuit is far too weak to defend against a 2.5x raise out of position; folding is clearly best.

T3 offsuit is a very weak hand even on the button in a 3-handed game; calling 100 chips risks more postflop with poor equity and playability.

96o out of position heads-up is too weak to play profitably; folding the cheap 50 loses little and avoids dominated spots.

Completing the small blind is inexpensive with a king-high hand and keeps the pot manageable out of position.

With 4-8 offsuit I have a weak hand, but checking is free and lets me see a flop in position against the limping small blind.

K-high has no meaningful draw on this connected flop, which is likely to connect with the big blind's range. Check and avoid building a pot with little equity.

Middle pair with weak kicker on a coordinated T-9-8 board; checking in position controls the pot and lets me evaluate the turn without bloating it against stronger pairs or draws.

Check behind with only king high and a draw to a king-high straight on a queen river. The connected board is dangerous, and betting has little value against the big blind after the flop checked through.

With a pair of 8s plus an open-ended straight draw on a checked-through board, betting denies overcard equity, can fold better weak hands, and builds value if called while we have many river outs.

The board gives me an open-ended straight draw, but with only one card to come its roughly 17% chance is well below the pot odds for calling 150 into 350. I have no made hand to continue with, so I fold.

AQ suited is a strong button-opening hand three-handed. Raise to 2.5 big blinds for value and to apply pressure to the blinds.

Q8 suited has solid equity against a wide button open and good playability, with favorable pot odds to defend from the small blind rather than folding or over-raising out of position.

J7 offsuit out of position against a raise and a call; weak hand with poor playability, so folding is cheapest.

Q-high with backdoor flush and straight potential is too weak to lead into the preflop raiser, but has enough equity to check and evaluate a flop bet.

A small continuation bet takes advantage of my preflop initiative and can fold out some overcard hands while retaining a cheap bluff with two overcards and a backdoor flush draw.

Calling 200 into 800 needs only 20% equity; Q8 hearts has two overcards plus backdoor flush and straight draws against a wide button range and a small flop bet.

Q-high with no pair and no viable draw on an ace turn; checking is free and avoids bluffing into the preflop raiser's ace-heavy range.

Bet 450 into the 1,000-chip pot for value with top pair and a strong kicker, while charging draws and weaker pairs. The opponent has checked, and the board is still relatively dry.

Q-high with no pair and no viable draw on an ace turn; pairing Q or 8 likely still loses to the raiser's ace-heavy range, far below the equity needed to call 450.

6-4 suited is below a profitable button opening or calling range three-handed, and playing it out of a limp risks dominated draws and reverse implied odds.

AQs is strong heads-up against the BB; raising builds the pot with position and folds out weaker hands.

7♣5♥ is a weak offsuit hand and calling a 3x raise out of position is unlikely to be profitable despite the pot odds.

K5 offsuit is a reasonable hand to complete heads-up from the small blind. Calling keeps the pot small while preserving its decent equity against the big blind's range.

With 2-5 offsuit in the big blind and no amount to call, checking is free and lets me realize equity without investing more with a very weak hand.

K-high has little immediate equity on this ace-high board, and checking preserves its modest showdown value without risking chips against a range that can contain many aces.

In position after the limper checks a dry ace-high flop, a small semi-bluff can win immediately and I still have a gutshot to the wheel if called.

K-high has no pair or immediate draw, and calling 150 requires too much equity against a bet on this ace-high flop. Fold and preserve the remaining stack.
