Hold'em table

Suited connected low cards have sufficient equity and playability to open from the button three-handed. I use a standard 2.5bb opening size.

K2o from the small blind facing a 2.5bb button open, with the big blind still to act, is a clear fold. Calling would leave me out of position with a dominated hand.

A9s on the button in a 3-handed game is a clear open-raise, so I'm making a standard 2.5bb open to take the blinds or play in position.

T2 offsuit is far too weak to continue out of position against a raise, and calling 200 more with poor equity is not profitable.

J9 offsuit has sufficient playability to defend the big blind against a button min-raise-like 2.5bb open, especially getting a favorable price heads-up.

Check to the preflop raiser with middle pair on this dry flop, keeping their bluffs and weaker hands in range.

A small c-bet in position on a board that favors the preflop raiser, with an ace overcard and backdoor straight and flush equity. It can fold out better hands or get value from worse ones.

Call with top pair and a reasonable kicker against the small continuation bet. Raising would isolate us against stronger queens and better jacks too often.

I will make a modest value/protection bet with my pair of jacks after the turn check, targeting draws and smaller pairs while avoiding an oversized pot.

The small turn lead gives good pot odds: 300 to win 1510, about 20% equity needed. I have a gutshot to a straight with any ten, ace overcards, and position, so calling beats folding. Raising as a bluff risks too much against a range that likely includes 7x and Jx.

Our pair of jacks has modest showdown value but is behind much of the opponent's likely continuing range, especially queens and sevens. Checking realizes equity without risking a thin value bet being called mainly by better hands.

Ace-high has some showdown value against the busted straight draws in the opponent's turn-lead range. A bluff is unlikely to fold out the Jx and 7x hands that check this river, so I'm taking the free showdown.

On the button with a playable hand, I raise to isolate the blinds and try to take down the pot preflop.

Qc5h offsuit is too weak to defend from the small blind against a button open, especially with the big blind still behind.

Getting about 3.7:1 against a wide 3-handed button open, 64o is a borderline but profitable big-blind defend. Calling keeps the pot small, and I can realize equity with position-independent draws.

This low monotone board favors the big blind's range. A pair plus an open-ended straight draw is a good candidate for a small lead that gets value, charges overcards, and gives some protection.

I have no pair, no diamond draw, and only overcards on a monotone flop, so calling is unlikely to be profitable against the opponent's bet.

K8 offsuit is a marginal button hand in this format; folding avoids entering a potentially difficult multiway pot.

Blind vs blind with suited 24, completing for 50 into 150 gives good odds, and the hand plays well enough for a limp, though we'll be out of position.

Pocket threes have decent equity but are not strong enough to raise for value here, so I take the free flop and realize my hand cheaply.

Bottom pair plus a backdoor flush draw in a limped pot, out of position; a small half-pot bet gets folds from overcards, protects my equity, and keeps the pot manageable.. BB checked back preflop, so their range is wide and weak.

Pocket threes have some showdown value against a wide small-blind range, and I'm getting 3:1 pot odds on a 100 chip call. I'll see the turn and fold to further aggression if I don't improve.

Bottom pair with no draw on a board that got worse for us. After villain called the flop, checking keeps the pot small and preserves some showdown value rather than bluffing into a range that likely beats us.

Bottom pair has modest showdown value against a big blind that checked through, so betting would mostly fold out worse hands and get called by better ones. Checking keeps the pot small.

With only pocket threes and the opponent checking both turn and river, checking gives us a chance to win at showdown against unpaired hands. Betting would only fold worse hands and get called by better ones.

K7 suited is a clear open from the button in 3-handed play, so I'm raising to 2.5bb to steal the blinds.

A8s has good equity and I am getting 2:1 pot odds to call 200, so calling is profitable. I avoid bloating the pot out of position with a marginal hand.

QsJh is a strong enough suited broadway hand to defend the big blind getting favorable multiway pot odds.

With no made hand and no club draw on a monotone board, I check to see the turn cheaply with overcards.

I have top pair with a solid kicker on a coordinated monotone board. Betting for value and protection pressures weaker queens, tens, and club draws.

K7 with no club on a monotone Q-T-4 board has almost no equity against a lead into two players, and there is still a player left to act behind me. Folding is clearly correct.

Pocket fours are well ahead of a typical big-blind defending range heads-up. Raising builds value and denies equity while keeping the pot manageable out of position.

A6 suited is well ahead of a small-blind open range, and calling 150 into a pot of 400 in position is a clear continue. Calling keeps the SB's weaker hands in; a 3-bet is also reasonable, but flatting in position works well.

With a small underpair on a king-high, two-club board, checking preserves showdown value and avoids inflating the pot out of position.

In position after the preflop raiser checked, a half-pot stab with ace-high, which blocks AK and AJ, can fold out better underpairs and deny equity. It also has backdoor diamond and wheel potential.

Pocket fours have little equity versus a flop bet on this overcard, two-club board, with few useful turn cards.
