Hold'em table

8-6 offsuit is a weak button holding for a three-handed unopened pot; folding avoids marginal reverse-implied-odds spots.

9-3 offsuit is a very weak hand out of position against the big blind. Calling costs 50 more to see a flop with poor equity, and folding loses only the 50 small blind already posted.

2-7 offsuit is the worst starting hand; folding on the button costs nothing and avoids a losing spot against two blinds.

Button folded, so it's SB vs BB heads-up; K5o is a standard open-raise from the small blind against a single opponent, and raising takes initiative rather than giving a free flop.

Jh9c is playable heads-up from the big blind against a small blind 3x raise, with favorable pot odds and position postflop.

Top pair of kings plus a backdoor-free but live 5h flush draw on a monotone Broadway board; a small 1/3-pot bet gets value from weaker pairs and heart draws while keeping the pot manageable given how coordinated the board is.

We have a king-high straight on a monotone broadway board. Raising for value and protection against flushes is preferable to flat-calling.

Top pair of kings plus a flush draw on a monotone board; getting ~3.7:1 on the call and opponent's check-raise range includes semi-bluffs with a single heart, so calling to see the turn is reasonable while raising would isolate against made flushes.

Out of position with second pair and a weak 5-high flush draw on a scary monotone-ish board after being check-raised; checking keeps the pot controlled and lets me evaluate the villain's turn action.

I have a strong combo draw: any heart makes an effectively nut flush, while any ten completes Broadway. A substantial turn bet can fold out marginal one-pair holdings and builds a pot when called.

Second pair with a weak 5-high flush draw on a monotone AKQ board facing a flop check-raise and a strong turn barrel; opponent's range is heavy with made flushes, straights and two pair, and our outs are tainted with poor implied odds, so folding is best.

AJo on the button in a 3-handed game is a clear value open; raising to 2.5bb puts pressure on the blinds and builds a pot in position.

T6 offsuit is too weak to defend from the small blind against a button raise with the big blind still behind.

5-2 offsuit is the worst starting hand. Calling 150 to win a pot of 400 out of position would lose chips over time, and the button's open range is wide, so a bluff re-raise is not worth the risk.

7-high offsuit is too weak to open from the button at this stack depth, especially with no prior action to exploit.

9-4 offsuit is a weak hand and would be out of position against the big blind. Calling 50 more is cheap, but the hand plays poorly postflop, so I fold.

7-6 offsuit on the button in a 3-handed pot is a marginal hand. Calling 100 to win a 250 pot gives good odds and I have position, so I'll take a cheap flop instead of folding.

AKo in the small blind facing a button limp is a clear value raise; isolate the limper and build the pot with a premium hand out of position.

2-5 offsuit is far too weak to defend against a small-blind raise with another player behind.

7-6 offsuit is a weak hand, and calling 350 to win 650 out of position against a small-blind raise isn't worth it. The pot odds are fine, but the hand plays poorly postflop and folding is the simpler choice.

J6 suited on the button in a 3-handed game is a standard open; raising to 2.5bb applies pressure on the blinds with position and playability.

9-high offsuit is too weak to defend from the small blind versus a button open, especially with the big blind still behind.

A7s-type hand (A7 offsuit) in the big blind against a button min-raise to 250 has good pot odds (150 to win 400) and position disadvantage is manageable; calling is better than folding or bloating the pot out of position. The ace blocker and decent equity make it a clear call. Correction: hand is A7 offsuit, still a profitable call at these odds.}

Top pair with a decent kicker (Ace-7) on A-3-5 against a button raiser who can have many weaker hands. I'll lead for value at roughly half pot, which also protects against draws and the wheel straight draws.

Jack high with no draw on an ace-high board facing a donk bet; no equity to continue and a bluff-raise is low value here.
