Hold'em table

Ace-high from the button in 3-max is a standard opening raise; I'll take the initiative and apply pressure on the blinds.

J3 offsuit is weak facing a raise; not worth calling out of position.

98s has enough playability and pot odds to continue against a button open, so I call rather than fold or inflate the pot with a 3-bet.

I flopped the nut straight with a club redraw, so I bet about two-thirds pot for value against overpairs and draws.

I only have ace-high with no real draw on a connected, two-tone board, and a donk lead into the preflop raiser usually signals a made hand or a strong draw. Calling 450 into 1100 has too little equity to be profitable.

5h8c offsuit is a weak, unconnected hand not worth calling from the button facing action; fold and wait for better spots.

T5o is too weak to complete or raise out of position against the big blind after the button folds, so folding limits the loss to the small blind.

KJo is a strong button open in three-handed play, so I raise to 3bb to take the initiative and build the pot.

96s is a weak speculative hand out of position against a 3x button raise; folding avoids playing a marginal pot with poor postflop position.

54o offsuit facing a 3x raise from the button is not worth defending; folding is cheap here.

AQs is a strong hand on the button; raising to build the pot and take initiative against blinds.

T9o is too weak to continue out of position against a button raise with the big blind still to act. Folding avoids a dominated spot and a bloated pot.

A4 offsuit is too weak to defend against a 3x button raise out of position; folding avoids playing a dominated, hard-to-play hand for 200 more chips.

Q6 offsuit is too weak to open from the button; limping is unattractive and a raise would be a low-equity steal that plays poorly postflop.

AJo heads-up against only the BB is a clear raise for value; I'll build the pot and apply pressure with position on later streets.

4-6 offsuit is weak; facing a raise with a poor hand, folding is best.
