Hold'em table

3d7h is a very weak offsuit hand with poor equity, so I fold to avoid investing chips with little chance of winning.

KQs is a strong heads-up hand after the button folds, and raising builds value while applying pressure to the big blind.

JTo in the big blind vs a small blind 3x open has good equity and plays well in position; getting 3:1, a call is clearly profitable, and 3-betting isn't necessary.

This paired board favors the caller's defended range, while KQ-high has limited immediate showdown value. Checking preserves flexibility and avoids inflating the pot.

Top pair with a decent kicker on a paired dry board after SB checked; a small bet gets value from worse Jx, 5x bluffs, and underpairs, and protects against overcards.

KQ has two overcards plus a gutshot on this board and comfortably continues versus the small flop stab. Calling preserves weaker hands and avoids inflating a paired-board pot out of position.

With only king-high on a paired board after calling the flop bet, checking controls the pot and preserves the chance to realize equity.

Top pair with a decent kicker on a paired, dry board. After the turn checks through to me, a roughly half-pot bet gets value from underpairs and weaker Jx and denies equity to overcards.

KQ high has no made hand or meaningful draw on this paired board, and the turn bet after a preflop raise and flop call is too strong to continue against.

J7 suited is a reasonable button open in short-handed play, with initiative and positional advantage.

A5o is a strong 3-bet candidate from the SB against a wide 3-handed button open: the ace blocks strong hands, it has playability, and it avoids a flat out of position with the BB behind.

5-4 offsuit is too weak to continue against a raise and reraise, especially out of position with poor equity. Folding preserves chips for better spots.

J7 suited performs poorly against a large small-blind 3-bet range, and calling 8bb out of position is not profitable.

Pocket eights on the button in a three-handed game are a clear open-raise. A 2.5bb open is standard and pressures the blinds.

T6o is too weak to continue out of position against a button raise, and calling 2bb with poor equity and no initiative is not profitable.

3-2 offsuit is too weak to defend against a button raise out of position at this sizing.

I have a suited connector in position, so calling one big blind is a reasonable way to see a flop cheaply.

I raise to isolate the limper and leverage my ace blocker, while giving the big blind and button a price that discourages loose multiway action.

Q7o out of position against a squeeze from the small blind, with a limper behind who can still act, is too weak to call 400 into 700. Folding is the clear choice.

My 4-3 suited is too weak to continue against a 5x raise from the small blind, and I'm not getting good enough odds to speculate. I'll cut my losses and fold.

7c6s is a playable suited-like connector only in structure, but offsuit; on the button it can profitably open at a modest size to leverage position and initiative.

34o from the small blind facing a button open with the big blind still to act is a clear fold; it plays poorly out of position.

95o is too weak to continue out of position against a button raise, and calling would put me at a big disadvantage postflop. Folding preserves my stack for better spots.

T2 offsuit is too weak to open profitably from the button against two blinds at 100bb, so I fold.

Q4o is weak, but I only need to call 50 into a pot of 150, giving good immediate odds to see a flop. I'll keep the pot small out of position.

Pocket sevens are well ahead of a typical small-blind limp range, and raising builds value while denying overcard equity.

Q4 offsuit is too weak to continue against a raise out of position, especially facing a 3x raise from the big blind. Folding preserves chips for a better spot.
