Hold'em table

Standard button open with a playable suited-ish connector-type hand in a 3-handed pot; raising here builds initiative since I act first preflop.

5-10o is a weak hand out of position in the small blind facing a raise. With 200 chips to call out of 10000, folding preserves chips for better opportunities. The raise from seat_1 suggests a decent hand, and my position disadvantage makes this fold mathematically sound.

Pocket threes have sufficient equity to defend the big blind against a button min-open-plus raise, especially heads-up.

With a weak underpair on an ace-high flop, checking preserves pot control and allows us to respond to the button's action.

As preflop raiser I'll continuation bet the ace-high board; BB checked which could indicate weakness, and I have decent fold equity even though my hand missed.

Call the small continuation bet with pocket threes; the opponent can have many unpaired overcards and we retain some showdown value and set-improvement outs.

Pocket threes have limited showdown value on this ace-king, three-heart board. Checking controls the pot and retains the chance to improve on the river.

I have no pair, no draw, and the board is heart-heavy (four to a flush) so betting air here is too risky against a caller.

Our pocket threes have little value on this coordinated board, but a bluff is unlikely to fold out enough of the opponent's ace-heavy range. Checking preserves our limited showdown value against missed holdings.

I have no showdown value (7-8 high) after opponent's passive turn/river checks, so a moderate river bet represents a strong hand and can fold out weak pairs or busted hearts draws.

Pocket threes are only a weak bluff-catcher on this ace-high, heart-heavy board. The river value bet after the flop continuation is unlikely to be bluffing often enough to justify a call.

Getting 3:1 from the small blind heads-up, 9-6 offsuit can profitably realize enough equity against the big blind's automatic range.

K5 offsuit is weak; checking for free to see the flop cheaply against a single limper.

Checking preserves equity with a weak hand and a low diamond draw on a paired board that favors the big blind's range.

I have king-high with no pair or strong draw on a paired board; checking is cheapest way to see next card.

With only a weak diamond draw and no made hand on this paired board, checking realizes equity cheaply and avoids building a pot against an opponent who can have many aces or jacks.

I have king-high with no pair or draw on a paired board with an ace; checking is free and safest.

A small river bluff can profitably target the opponent's many unpaired, missed holdings after they checked every street. Our hand has no showdown value, so betting is preferable to checking.

I only have king-high with no pair on a paired board with an ace out; a river bet here is very unlikely to be a bluff worth catching.

Button open with suitedness absent but connected 65 has playable equity three-handed; raising can win blinds and retain initiative.

K2o is a weak hand facing a 3x raise from the button. With limited equity against a raising range and poor position postflop, folding preserves chips for better opportunities.

Button steal with a suited hand in a 3-handed pot; raising to 250 applies pressure on both blinds.

J9o is a weak hand from the small blind facing a 250-chip raise (2.5x the big blind). The raise suggests strength, and we're out of position with marginal cards. Folding preserves chips for better opportunities.

T2 offsuit is too weak to defend against a button raise, even with the blind already invested.

Q7o is a weak hand in this position. Folding avoids playing a marginal hand out of position against two opponents who have already committed chips to the pot.

Closing the action in the small blind, Q7 suited has enough equity to realize value heads-up for the additional 50 chips.

I'm big blind with weak offsuit cards (5-9), no raise to call, so I check and see a cheap flop.

In this limped heads-up pot, Q-high with only a gutshot is not strong enough to build the pot out of position. Checking preserves equity and allows a response to a later bet.

No pair, no draw, and no bet to face, so checking back with 9-high is the right choice.

Betting the turn applies pressure to a passive checked range while leveraging an open-ended straight draw to the nut straight.

I only have a gutshot straight draw with no pair, and the pot odds don't justify calling a bet on the turn with such weak equity.

Button opening K5 suited is profitable three-handed; a 2.5bb raise applies pressure while retaining positional advantage.

Qd8d is a weak offsuit hand facing a raise from the button with a player still to act behind; not worth calling out of position.

Ad3d is a weak hand even with the ace. Facing a raise to 250 from button after folding small blind, folding preserves chips with a marginal hand that plays poorly out of position postflop.
