Hold'em table

Nine-three offsuit is one of the weakest hands even from the button in a 3-max game; folding avoids playing a dominated hand out of position postflop.

5-9 offsuit is weak, button folded, and facing BB with a mediocre hand isn't worth defending for 50 more chips.

5-2 offsuit is one of the weakest starting hands; folding from the button preflop is correct against a call requirement.

Button folded, so this is heads-up versus the big blind. 97o is weak but the price to call is only 50 into 150, which is enough to continue rather than fold.

A7s is a strong heads-up hand against a limper; raising to 300 builds the pot with likely the best hand and takes initiative.

97 offsuit is too weak to continue against a raise, especially out of position. Folding avoids putting more chips in with a hand that plays poorly postflop.

KTo is a standard button open in three-handed play; raising to 2.5bb builds the pot and takes the initiative rather than limping or folding.

QTo offsuit is frequently dominated by a button's opening range and plays poorly out of position with the big blind still to act. Folding is the highest-EV option.

J3 offsuit is weak; facing a raise with poor equity, folding is correct.

7c3s offsuit is one of the worst hands in hold'em; with only 150 in the pot and two players left to act behind the blinds, folding loses nothing and preserves chips.

K3 suited on the button is a reasonable raising hand heads-up-ish; raising to 250 to build pot and take initiative.

83 suited is too weak to call a button raise from the small blind with the big blind still to act.

QTo has enough equity against a 2.5x button open to defend my big blind cheaply, and I close the action preflop. I'll play cautiously postflop out of position.

As preflop raiser I'll continuation bet the ace-high flop; opponent checked, showing weakness, and I can represent the ace with a mid-size bet.

I hold TcQd with no pair and no meaningful draw on an A-9-2 board; calling 300 into this pot with only overcard-gutshot hopes is unprofitable, so folding is clearly best.

K3 offsuit is too weak and dominated to open from the button for 100 chips; folding preserves the stack.

Heads-up against only the big blind, J9s has solid equity versus a wide calling range. A min-raise builds the pot with initiative and fold equity rather than limping out of position.
