Hold'em table

Button open with suited connectors Ts9s; a 2.5bb raise builds the pot and takes initiative before the blinds.

J3 suited is too weak to defend from the small blind against a button open with a big blind still to act; folding is the standard play.

Q6 suited is too weak to defend against a button open in this short-handed configuration.

7s4s is a weak suited hand even on the button in 3-handed play; folding avoids spewing chips with a hand that plays poorly postflop against two opponents.

Q2 suited is worth completing heads-up from the small blind at this price, retaining equity and positional disadvantage without inflating the pot.

67o is too weak to raise out of position, and checking is free after the small blind completes.

With only queen-high and little board interaction in a limped pot, checking preserves showdown value and avoids inflating the pot against the big blind's range.

I have an open-ended straight draw on a checked flop and position, so a half-pot semi-bluff can fold out weak hands or build the pot when I hit.

Queen-high with no spade, no pair, and no meaningful draw has insufficient equity or bluffing prospects against the big blind's flop bet.

On the button in a three-handed game, 7-8 offsuit is playable as an open-raise and benefits from initiative and position.

Q6 offsuit is too weak to continue from the small blind against a button open; folding is the highest-EV option.

3-5 offsuit is a weak hand out of position against a button open; folding is standard despite decent pot odds.

T3 offsuit is too weak to open from the button for a full big blind, so folding preserves chips.

Button folded, so it's SB vs BB heads-up with 8s6h; a small raise to 3bb applies pressure and 86o has enough playability to open against a single opponent with position disadvantage mitigated by fold equity.

8c4h offsuit is too weak to defend against a small-blind raise even with the favorable price.

7-5 offsuit on the button in a 3-handed game is a marginal hand; folding first to act avoids playing a weak holding out of position relative to the blinds' decision to defend or 3-bet.

Pocket eights are strong heads-up against the big blind; raising builds value and avoids giving a free flop.

95o is too weak to continue against a 3bb open heads-up from the small blind; folding saves chips.

5-3 offsuit is a very weak button hand and not worth entering against two blinds.

J4o is too weak to call or raise heads-up from the small blind against the big blind.
