Hold'em table

A6o on the button in a 3-handed game is strong enough to open-raise; a 3x raise pressures the blinds and takes initiative.

4-2 offsuit is far too weak to defend from the small blind versus a button 3x open.

King-Five offsuit is a weak hand, and facing a 3x raise from the button after seat 2 folded, calling 200 more chips into a multi-way pot offers poor value with a hand that's likely dominated. Folding minimizes losses.

Button open with a playable suitedness-independent J7 offsuit can profit from initiative three-handed; use a standard 2.5bb raise.

5-2o is the worst hand in poker. Facing a raise to 250 from the button after posting the small blind, folding is the mathematically correct decision. This hand has no showdown value and minimal equity against a range that includes a raise from the button.

With 6h8c out of position against a button raise, calling 150 to defend is marginal and postflop playability is poor, so folding preserves chips.

Getting 3:1 pot odds heads-up with Q3o, calling is cheap and keeps a hand with reasonable equity versus the big blind's range. Raising out of position with a weak offsuit queen is riskier than necessary.

Checking preserves position and realizes equity with a weak king in a limped heads-up pot.

I have Q-high on a dry flop with no strong draw. Checking keeps the pot small and avoids bluffing into an unknown opponent who could easily have a pair or better.

I have top two pair on a dry board and should build the pot while drawing value from weaker kings, pairs, and loose floats.

86o is too weak to call a full big blind from the button in a 3-handed game; folding avoids playing a dominated offsuit hand with poor postflop potential.

With the button folded, K-high has enough heads-up value and fold equity to raise from the small blind. I use a standard 3x sizing.

7-Jack offsuit is a weak hand against a raise from the small blind. With 200 chips to call and a sub-standard holding, folding preserves chips for better opportunities.

A6 offsuit is a clear button open three-handed, with ace blocker and positional advantage. I use a standard 2.5bb sizing.

K2o is a weak hand that doesn't warrant investing further against an early raiser. Seat 2's raise to 250 from the button suggests strength, and folding preserves chips for better opportunities.

Closing the action with 150 to call into a 400 pot, J7o has enough equity against a button open, and the call is cheap. I'll defend but proceed cautiously out of position.

Middle pair with J kicker on a coordinated board; checking to control the pot and evaluate the button's action.

This connected flop favors the big blind's calling range, and our weak pair has limited value facing a check-raise. Checking back preserves showdown value and realizes equity.

I have two pair (9s and 7s) with a J kicker. The board is draw-heavy, so I bet for value and protection.

I have a pair plus the nut-flush draw, giving enough equity and river improvement potential to continue versus this modest turn lead.

I have nines and sixes with an ace kicker after the river check. A medium value bet can be called by worse pairs and sixes while limiting exposure to stronger nines or a straight.

King-high with decent kicker in late position (button) justifies an aggressive raise. This iso-raises the blinds and builds the pot with a playable hand, standard button strategy against weak action.

T2o is a weak offsuit hand out of position facing a button raise; folding avoids bleeding chips with poor playability.

J3 suited is too weak to defend against a button 3x open out of position, especially with the small blind already folded.
