Hold'em table

J9s is a solid speculative hand on the button in 3-max; opening for 3x builds the pot with position and folds out weaker hands.

K4o is too weak to continue from the small blind against a button open to 3bb; folding avoids a dominated, poorly connected hand out of position.

K3 offsuit facing a 3x raise from the button is a weak, dominated hand not worth defending out of position for more chips.

K7o is a standard wide button open in three-handed play; a 2.5bb raise takes the initiative rather than limping or folding a playable king.

53 offsuit is a weak hand facing a raise; folding is standard here.

Queen-nine offsuit is dominated too often against a button 2.5x raise, and playing out of position with a marginal hand risks more than the 150 call is worth.

Small pocket pair on the button; raise for value/set equity while chip stacks are deep.

Pocket tens is ahead of a button open range, so I 3-bet to 1000 for value and to take the initiative heads-up.

74s is far too weak to play even from the button 3-handed; folding the 100 chip call avoids bleeding chips with a dominated, low-equity hand.

Button folded, so this is heads-up versus the big blind. Q7 suited is strong enough to raise for initiative rather than just complete.

2-5 offsuit is a weak hand facing a raise; folding is correct here.

94o is too weak to open even on the button in a three-handed game; folding avoids playing a dominated, poorly connected hand out of position postflop if called.

Q5 offsuit is weak; button folded but BB still to act behind, not worth calling with a poor hand heads-up out of position.
