Hold'em table

K6o on the button is worth an open raise for position; a standard 3x raise applies pressure and can win preflop or take initiative postflop.

My hand 2h 8d is extremely weak and has no playability, especially from the small blind with poor position. Folding is the clear choice to preserve chips.

On the button with K9o, raising to 3bb applies pressure on the blinds and takes initiative with position.

Q7s is too weak to call 3bb preflop against a button raise out of position; folding is the profitable play.

Opening a suited connector from the button in 3-handed to pressure the blinds and retain the initiative.

KTo out of position against a 2.5x button raise is a marginal hand; folding avoids playing a dominated spot heads-up.

QJo is a strong button hand in a 3-handed game, so I raise to apply pressure and take initiative preflop.

Facing a button raise with 9c6c from the big blind, I'm getting 2.25:1 pot odds to call 200 into 450. Suited connectors have decent implied odds, so calling to see a flop is profitable long-term, even out of position.

I have only a pair of sixes on a board with Ace, King, Ten, and three hearts. Seat 3 has been aggressive and likely has a stronger hand. The pot odds don't justify a call with such a weak made hand.
