Hold'em table

T7 offsuit is a marginal button open, but position and the unraised pot make a small raise reasonable.

64s out of the small blind facing a button open, with the big blind still left to act, is a weak spot: out of position with a hand that doesn't play well. Folding is standard here.

9-2 offsuit is too weak to defend against a button raise, especially out of position.

62o is too weak to open even from the button in 3-handed play against two blinds, so folding is the standard play.

Complete from the small blind with a suited-ish connected hand? 8-6 offsuit has enough heads-up equity to see a flop cheaply.

K-J suited is strong against a small-blind limp, and raising builds value while leaving room to play postflop in position.

8-high offsuit is too weak to defend against a 4bb isolation raise out of position.

KJs is a strong button opening hand three-handed and benefits from taking initiative with a standard open size.

K4 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act.

A5s in the big blind against a wide button open is a good 3-bet bluff candidate, since the ace blocks strong hands and the hand plays well when called. Calling is also fine, but a 3-bet to 10bb applies pressure.

KJs is a strong suited broadway hand with position and plays well against a big-blind 3-bet. Calling preserves flexibility while keeping weaker hands in their range.

The low connected 876 two-tone board hits the button's flatting range hard, so from out of position I'll check my ace-high gutshot and keep my range protected. I can decide on facing a bet based on sizing.

Check back with two overcards but no made hand or immediate straight draw on a coordinated board. This preserves equity and avoids facing a check-raise in the 3-bet pot.

Open-ended straight draw (a 4 or 9 makes the straight) with an ace overcard, and villain checked back the flop showing weakness. A semi-bluff of about 60% pot can fold out AK/AQ-type hands and still has solid equity when called.

K-high has no made hand or straight draw on this paired connected board, and the turn lead from the preflop 3-bettor is too strong to continue against.

Nine-three offsuit is too weak to open from the button, even three-handed.

Blind vs blind, 65o is a reasonable raise or limp; raising to 3bb applies pressure and takes the initiative against the big blind.

A5 suited is a strong heads-up blind-versus-blind hand with blocker value. A larger 3-bet can capture the dead money and retain initiative.

65o out of position against a 3-bet, with 600 to call into a 1,800 pot after calling, doesn't realize enough equity. It also lacks the blockers to make a 4-bet bluff worthwhile, so I'm folding.

On the button 3-handed, 74s is a reasonable steal; a small open to 2.5bb puts pressure on the blinds.

AJs is a strong three-handed hand and performs well as a value-oriented 3-bet. Raising also applies pressure to the button’s opening range and can isolate or take down the pot preflop.

A9 offsuit is often dominated by the small blind's large three-bet range, and the button has yet to act. Folding avoids a costly marginal spot.

74s does not realize enough equity against a large 9bb three-bet, even in position, so folding is the disciplined play.

7-3 suited is too weak to open from the button under standard three-handed ranges; folding preserves chips.

A9 offsuit is strong heads-up against the big blind’s wide range, so I raise for value and initiative.

In the big blind against a small-blind open to 3bb, 86o gets 3:1 pot odds (200 to win 600 total) and I have position postflop, so calling is profitable against a wide blind-vs-blind range.

Top pair with a heart flush draw is strong enough to value-bet and protect against weaker pairs and draws. A modest bet keeps weaker hands in without building the pot too aggressively.

We have a flush draw plus a gutshot to a 7, about 12 outs, and are getting better than 4:1 in position. Calling is clearly profitable, and raising a non-nut flush draw is unnecessary.

Top pair can get value from weaker aces and hands with a heart while charging draws. A moderate bet limits the pot against stronger made hands.

We have an 8-high flush. That beats many value hands, but larger flushes are plausible, so calling the small bet keeps the pot controlled and keeps villain's bluffs in.

Top pair can get thin value from weaker aces and kings. A small river bet keeps those hands in while limiting the cost when I'm behind.

I only have 8-high: the flush and straight draws both missed, so calling beats almost nothing. A bluff raise needs too many folds against a range that has been value-betting Ax on every street.
