Hold'em table

75o is below a standard 3-handed button opening range at 100bb, so folding is the disciplined play.

AK suited is a strong hand, so I raise to take initiative and put pressure on the big blind while keeping the pot manageable.

7-3 offsuit is far too weak to defend against a small-blind raise heads-up.

I have a suited connector with position on the button, so I raise to take initiative and put pressure on the blinds.

A3o has an ace blocker and benefits from applying pressure against a button min-raise. A larger small-blind 3-bet can take down the dead money or play a lower SPR.

64o facing an open and a 3-bet with the original raiser still to act behind is a clear fold; calling 600 more out of position isn't profitable.

T8s is suited and I have position, getting good pot odds to call the 3-bet and see a flop.

With only ace-high on this coordinated flop after a preflop 3-bet pot, checking preserves flexibility and avoids inflating the pot out of position.

I flopped top pair and want to extract value from worse hands while charging overcards and draws, so a half-pot bet is appropriate.

I have the nut-heart flush draw plus an ace overcard against a small continuation bet. Calling preserves the opponent's bluffs and realizes my equity.

With the nut-heart draw and a gutshot, checking realizes substantial equity without risking a check-raise against a range that can contain strong kings and made hands.

My pair of tens is likely behind many of the opponent's 3-bet calling range on this K-Q-T board, and checking keeps the pot small while I still have showdown value.

The river completes the obvious Jx straight after our flop lead and turn check, giving us a credible polarized bluff. Ah also blocks some potential heart-draw continues while our ace-high has little showdown value.

J7 suited has reasonable button playability three-handed, and a small open can pressure the blinds while retaining positional flexibility.

87o in the small blind facing a 2.5x button open with the big blind still to act is a clear fold; calling out of position is unprofitable, and 3-betting with this hand is too loose.

3h5c is too weak to continue out of position against a raise, and calling would likely lose chips over the long run. Folding preserves my stack for better spots.

97o on the button in 3-handed play is a standard open; a small raise to 2.5bb applies pressure on the blinds.

7-2 offsuit is a very weak hand facing a raise, and calling 200 more out of position is not profitable.

T7 offsuit has sufficient equity to defend the big blind against a likely wide button min-raise-plus opening, especially heads-up with favorable pot odds.

Check to the preflop raiser with an open-ended straight draw, preserving flexibility to respond to a continuation bet.

An open-ended straight draw on a paired board makes a good semi-bluff continuation bet in position after the check. A small sizing works well on this dry, paired texture.

I have an open-ended straight draw and favorable pot odds versus the small continuation bet. Calling keeps weaker hands and bluffs in while preserving flexibility.

Our ten kicker is weak on this paired board, and a turn bet is unlikely to get enough better kickers or pocket pairs to fold. Checking preserves our equity and avoids being raised off the hand.

On a trips-8 board, we effectively have 9-high with an open-ended straight draw. A free card realizes our equity, and a bet is unlikely to fold the better hands that called the flop.

A river bet can credibly represent a full house or quads after the checked turn. Our showdown value is weak on this paired board, so I apply pressure to fold out unpaired overcards and weaker trips.

Our 9-high straight beats every trips hand and any bluff, but it loses to the many full houses in the big blind's range (any 5, 6, pocket pair or 8). Raising would mostly get called by those hands, while calling needs only about 27% equity.

KQs is a strong hand on the button, and I can apply pressure on the blinds while having position postflop. A raise to 300 should take the pot down often or give me control in a 3-handed hand.

Pocket threes are strong enough to defend the small blind against a button min-raise, especially with the big blind still behind. Calling keeps weaker hands and implied-odds opportunities in play.

Q6o is dominated often and realizes its equity poorly in a multiway pot, so it is a marginal defend even at 3.5:1 pot odds. Folding is fine here.

With a low pocket pair on a coordinated monotone flop, checking keeps the pot controlled and preserves showdown value.

Checking to keep the pot small with no made hand on a monotone board, and I can see a free turn after the opponent checked.

The fourth diamond is an excellent scare card after villain checked back the monotone flop. A small polarized bet can fold out non-diamond overcards and pairs while risking relatively little.

I have only king-high with no diamond on a four-flush board, so calling cannot be profitable against the turn raise.

K8 suited is a playable button open in three-handed play. Raising applies pressure and takes initiative with positional advantage.

75o from the small blind facing a button open, with the big blind still to act, is too weak to call out of position or 3-bet profitably. Folding.

J6o is too weak to continue out of position against a raise, and calling would likely lead to difficult postflop spots. I fold to avoid being dominated.
