Holdem table

With T9o on the button in a 3-handed game, raising applies pressure on the blinds and uses position with a speculative hand. A 300 raise is large enough to take initiative without overcommitting.

4-5 offsuit is a weak hand, especially out of position as the small blind facing a raise to 300 chips. Folding is the mathematically sound decision against a 3x raise from the button.

Pocket sevens are well ahead of a button opening range and make a strong value/protection three-bet from the big blind.

T9o is too weak to continue against a big blind 3-bet, even in position. Calling 600 more would often leave me dominated, so folding preserves chips.

5-2 is the weakest hand in poker ("the five-deuce"). Even in position on the button, this hand is not worth defending. Folding here preserves chips for better opportunities.

3-2 suited is too weak to defend routinely from the small blind against the big blind.

J7 suited has reasonable playability on the button in a three-handed game; raising can leverage position and initiative.

T6o is too weak to continue against a button raise from the small blind.

K3o is a weak hand facing a 2.5x raise from the button after the small blind folded. Folding preserves chips when dominated by the raiser's likely range and avoids playing out of position postflop with a marginal holding.

Three-handed button with an ace, raising applies pressure and takes initiative with position. I will fold to a 3-bet.

Q-3 offsuit is a weak hand that struggles against a raise from the button. Folding preserves chips and avoids a marginal spot out of position.

6-5 offsuit is a marginal, poorly realized hand out of position versus a button 3x open. Folding avoids defending too wide.

5c-Jc is a weak hand in this position. With only a Jack-high and no connected cards, the odds are unfavorable against two opponents, especially facing a bet from the big blind. Folding preserves chips for better opportunities.

J6 offsuit is a weak small-blind holding versus the big blind, with poor playability and reverse-implied-odds risk. Folding preserves chips.

Pocket jacks are a premium button opening hand. I raise to build value and pressure the blinds.

8h3c is a very weak offsuit hand facing a button raise with the big blind still to act; folding avoids investing more chips out of position.

K5o is a weak hand in a 3-way pot, especially facing a raise to 300 from the button after the small blind folded. My position and hand strength don't justify calling a significant raise when there are better opportunities ahead.
