Hold'em table

Q8o is slightly too weak to open profitably from the button even in 3-handed play, making fold the standard play.

AJo is a strong hand heads-up against the big blind after the button folded. Raising to 3bb for value and to take the initiative is better than limping.

T6 offsuit is marginal, but getting 2-to-1 against a small-blind raise and having position postflop makes a call reasonable.

Top pair with ace kicker on a dry K-8-4 flop, heads-up and first to act. A small value bet of about 2/3 pot builds the pot and charges worse kings-free holdings and draws.

Ten-high has no pair or immediate draw on this flop, so calling the bet is unlikely to be profitable.

Q7 offsuit on the button is a marginal hand that plays poorly against two opponents when out of position postflop, and folding avoids a weak call for 100.

With the button folded, Q6 offsuit is worth completing the small blind for 50 chips, but it is not strong enough to build a large pot out of position.

A high offsuit has strong equity against a small blind limp range; raising to 4bb builds value and takes the initiative in position.

Q6 offsuit plays poorly out of position against a large raise, so calling 300 more is unlikely to be profitable.

Q6 offsuit is a reasonable button open three-handed. Raising to 2.5 big blinds gives me a chance to win the blinds while keeping the pot manageable.

Three-betting 76s from the small blind as a balanced bluff against a button open to take initiative and fold equity.

6-2 offsuit is the worst kind of hand, and facing a 3-bet to 1000 with a button caller still to act, calling 900 more is clearly unprofitable.

Q6 offsuit is too weak to continue against a large three-bet, even with position.

T2s is too weak to open profitably even from the button in 3-handed play.

9s8c is a decent suited-less connector; button folded, so completing the small blind for 50 more gets good pot odds (3:1) heads-up against the big blind, and it keeps the pot small out of position.

Pocket deuces can see a free flop, and raising would build a pot with a hand that is difficult to play without a set.

Bottom pair (eights) with a backdoor flush draw and a gutshot (9-8 on J-8-K needs a 10 for Q-10... actually 9 with J, K needs Q/10 for a straight), heads-up out of position. A small bet of 100 into 200 gets value from worse pairs and draws, and denies equity cheaply.

A pair of deuces is unlikely to be ahead on this K-J-8 flop, and improving against a bet is too unlikely to justify calling.

T4 offsuit is a weak hand out of position postflop against two opponents, so folding on the button rather than paying 100 to call is the disciplined choice.

Q7 suited is strong enough to raise heads-up against the big blind, and a 2.5bb open keeps the risk modest.

T2o is too weak to defend even against a small blind open.

J5 suited is playable from the button in a three-handed game. A small raise gives it a chance to win the blinds while retaining position if called.

Holding T2 offsuit in the small blind facing a button open is an easy standard fold.

Q5o in the big blind getting 400 to 150 (about 2.7:1) against a wide button open in 3-handed play. Calling is profitable enough, and a 3-bet bluff with this hand is unnecessary.

Top pair (queens) with a weak kicker on a fairly dry board, heads-up and first to act out of position. A bet of about 64% of the pot gets value from worse queens and nines and draws, and denies equity to overcards.

J-high has little immediate equity on this flop, and the 350-chip bet makes chasing backdoor draws unprofitable.
