Hold'em table

A3 offsuit is strong enough to open on the button in a three-handed game, and a 2.5 big-blind raise applies pressure without overcommitting.

A9o is a strong enough 3bet bluff/value hand from SB vs a button minraise; taking initiative and folding out BB's equity is better than calling OOP.

65 offsuit is far too weak to call a 3-bet to 10bb out of position.

A3 offsuit is often dominated by a small blind 3-betting range, and calling 750 more creates a difficult postflop spot despite having position.

T3o offsuit is too weak to open from the button against two blinds; folding avoids investing chips with a hand that has poor equity and playability.

A7s is a prime blind-versus-blind raising candidate; raising to 300 applies standard pressure on the big blind.

Heads-up against a small-blind raise, 8♠4♠ is worth defending at this price, especially with position after the flop.

Check out of position on a board that heavily favors the big blind's defending range with an overcard, gutshot, and backdoor flush draw.

The check gives me a chance to win the pot with a small bet. If called, I still have a gutshot straight draw and some ways to improve.

I have an open gutshot to the nuts with an overcard Ace and backdoor flush draw getting over 3:1 pot odds.

Check to control the pot with ace-high and a gutshot straight draw out of position.

The turn gives me an open-ended straight draw. Betting can fold out some better unpaired hands while leaving me outs when called.

Holding only an ace-high gutshot with no flush draw, calling a 68% pot bet on the turn offers insufficient pot odds and implied odds.

Opening with pocket Queens on the button for standard value and position.

42 suited is too weak to defend the small blind against a button raise, especially with the big blind still to act.

4d8c is too weak to defend out of position against a button raise; folding avoids playing a dominated hand.

Nine-five offsuit is too weak to open profitably from the button against two players.

The button folded and I only need 50 more to complete with T6o, which has reasonable equity against a random big blind. Calling keeps the pot small; I can fold if the big blind raises.

Holding pocket threes in the big blind facing a small blind completion, checking behind lets us see a free flop in position with good set-mining potential.

With T6 into an A-high flop and only one opponent, I have little equity and no strong draw; checking keeps the pot small and avoids putting chips in as a bluff out of position.

Holding an underpair on an ace-high dry board, checking behind takes a free turn card with minimal showdown value.

I have an open-ended straight draw and both opponents checked the flop, so a turn bet applies pressure and can win the pot outright while still improving on the river.

Holding an underpair of threes on a board of A-Q-J-8 with multiple straight and pair possibilities offers virtually zero equity or drawing outs to justify calling a turn bet.

9h6c is too weak to continue from the button against two opponents, even with position, and we are not closing the action preflop.

63o is far too weak to complete or raise from the small blind out of position.

Standard 2.5x open-raise on the button with pocket sixes in a 3-handed dynamic.

Nine-deuce offsuit is too weak to defend the small blind against a button raise, especially with the big blind still to act.

J5o is a weak hand out of position against a button raise; folding avoids losing more chips with a marginal holding.
