Hold'em table

Opening small on the button pressures both blinds while preserving positional advantage. Suited 7-4 has enough postflop playability to serve as a marginal steal candidate.

5c9c is too weak to defend from the small blind against a button raise, especially out of position and with the big blind still to act.

92 offsuit is too weak to defend against a button raise, even with favorable pot odds. Its poor playability out of position makes folding preferable to calling or bluff-raising.

A7o on the button in 3-handed is strong enough to raise for value and to steal the blinds; 2.5x is a standard sizing.

73 offsuit is too weak to defend against a 2.5bb button raise from the small blind, with poor playability out of position and the big blind still to act.

Calling costs 150 to contest a final pot of 550. Against a button opening range, 5♣4♣ has sufficient equity and suited-connector potential to defend the big blind at 100bb depth.

With no pair beyond the board and only a backdoor club draw, this hand has little equity. Checking to the preflop raiser avoids investing chips with a weak bluff candidate.

干燥翻牌，作为翻前加注者持续下注代表K，期望迫使对手放弃未击中的牌直接收池。

Five-high has negligible showdown value and no meaningful draw on this paired, high-card flop. With no useful blockers or strong backdoor prospects, folding is better than calling or bluff-raising.

Pocket sevens are a clear button open three-handed. Raising to 2.5 big blinds builds value against weaker hands and pressures the blinds while retaining positional advantage.

T6 suited is too weak to defend profitably from the small blind against a 2.5bb button raise, with the big blind still to act. Folding avoids a marginal pot out of position.

Q7s is playable from the big blind getting 150 to 400 against a button open, and it can flop well; folding is too tight and raising out of position with this hand is unnecessary.

I have top pair with a weak kicker out of position; checking to the preflop raiser is standard to control the pot and gather information.

Sevens have showdown value but get limited value from worse hands on this two-overcard flop. Checking back controls the pot and preserves our ability to call selectively on later streets.

Betting for value and protection with top pair, weak kicker, on a board with a flush draw.

The big blind can probe this checked-through flop with draws and weaker hands, so 77 has enough showdown value to call at roughly 26% required equity. Calling keeps those bluffs in while allowing a river reassessment in position.

We have second pair with a weak kicker and the river brings an overcard. Checking controls the pot and lets us see the opponent's action before committing more chips.

Sevens retain showdown value against missed draws and weaker turn stabs. Betting is unlikely to get called by worse, and without useful blockers, bluffing to fold out a queen or nine is less attractive than checking back.

86 offsuit is a marginal button open with weak high-card value and limited playability. Without evidence that the blinds overfold, folding avoids a low-value investment.

Q3o is too weak to play out of position against the big blind, especially with no fold equity and poor postflop playability.

On the button with Ac6c, a standard raise puts pressure on the blinds and can win the pot immediately or play with position.

J9 offsuit is too weak to defend profitably from the small blind against a 2.5bb button raise with the big blind still to act. Its limited playability and domination risk make folding preferable.

Calling costs 150 to contest a final pot of 550, and T8 offsuit has enough equity against a typical button opening range to defend the big blind without rake. Raising would unnecessarily inflate the pot out of position with a marginal hand.

With ten-high and no direct draw on a dry queen-high flop, checking is preferable to leading into the preflop raiser. This board generally favors their range, and our hand has little equity to support a bluff.

We have middle pair with overcard kicker on a dry flop. Checking back controls the pot and may induce a bluff or get value on later streets.

Ten-high has no direct draw, and the king favors the button's preflop raising range. Checking avoids investing in a low-equity bluff on an unfavorable turn.

I have a weak pair of sixes with ace kicker, and my opponent has shown no aggression by checking twice. Checking behind allows me to see a free river and avoid a potential check-raise while still having showdown value.

Ten-high has very little showdown value, while the opponent's checks on both streets leave many unpaired hands in their range. A roughly two-thirds-pot bluff can fold out ace-high and other hands that beat mine.

I have a weak pair of sixes with an Ace kicker on a board that contains a King and Queen. My opponent's river bet represents a made hand, and I beat almost no value hands. The pot odds are close but my hand is too weak to call as a bluff catcher.

With no rake and the button, K3 offsuit is a reasonable marginal steal at a minimum raise. The king blocks some strong defending hands, and the small sizing limits risk while preserving position postflop.

42 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act. Folding avoids investing more with poor equity and positional disadvantage.

J4o gets 3.5:1 pot odds against a wide button open in a 3-handed game, so calling is slightly +chip EV despite position disadvantage.

We have J4o on a paired board with no draws; checking is the only sensible option given our weak hand.

A one-third-pot continuation bet pressures the big blind’s unpaired hands at low cost. As the preflop raiser, I retain the overpair advantage on this paired board.

We have J-high with no pair or draw on a paired board, and facing a bet, folding is the best play to preserve chips.
