Hold'em table

J4 offsuit from the button is far too weak to play even 3-handed; folding preserves chips for better spots.

With the button folded, J-7 offsuit is reasonable to complete heads-up, and calling 50 offers favorable pot odds.

I have 8d 4c in the big blind and the small blind just completed. Taking the free flop is standard with a weak holding.

My hand has no pair or flush draw, and this ace-high board favors the big blind’s range. I’ll take the free card rather than bluff with little equity.

I have second pair with a weak kicker on an Ace-high board; checking behind controls the pot and realizes equity.

With only jack-high and no meaningful draw, betting has little value. I’ll check and preserve the chance to reach showdown cheaply.

I have two pair with a weak kicker on a paired board; checking behind controls the pot and takes the free showdown equity.

I have a reasonable showdown hand with two pair, aces and jacks, but the river completes the spade draw. Checking avoids building a pot against stronger hands and lets me reach showdown.

I have two pair, Aces and Eights, with decent showdown value in a limped blind-vs-blind pot, so checking behind to realize equity is the safest play.

As the button, I can apply pressure to the blinds with a small open; 4-5 has some connectivity if called, though it is a marginal hand.

Holding T5 offsuit in the small blind against a button open is an easy fold out of position.

J4o is far too weak to defend the big blind out of position against a 2.5x button raise; I'm dominated too often and lack playable equity postflop.

62s is too weak to open profitably even on the button in 3-handed play.

Heads-up in the SB, 82c is playable and I have position; a small raise pressures the BB and can win the pot preflop or build a pot with a flush draw.

K♦T♦ is strong enough to defend against a small blind raise, and calling keeps weaker hands in while avoiding a large out-of-position pot.

My 2c8c has almost no equity on K-J-J; the big blind's calling range hits this board far too often for a bluff to profit, so I check and give up unless the turn changes things.

I have top pair with a reasonable kicker and can get value from weaker kings while charging overcards and straight draws. A small bet keeps worse hands in and limits the cost if raised.

I have 2c8c on a K-J-J board with no draw; seat_2's flop bet likely beats my air, so folding is cheapest.

JTs suited is a premium 3-handed hand and I have position on the button, so I open-raise to 300 to build the pot and apply pressure on the blinds.

9♥5♠ is too weak to call a 3bb button raise from the small blind, especially with the big blind still to act.

T6o is too weak to defend out of position against a 3bb raise from the button.

7♦4♣ is a weak offsuit hand, and calling invites the blinds in while playing poorly postflop. I’ll fold rather than invest from the button.

93 suited is too weak to complete or raise out of position against the big blind.

AJo is a strong opening hand on the button in 3-handed play; raising to 2.5bb builds the pot with a positional advantage.

85 offsuit is very weak facing a 2.5x raise out of position; folding is clearly best.

K2 offsuit is too weak to defend out of position against a 2.5x button raise, despite the pot odds. Folding avoids entering a pot with poor postflop playability.
