Hold'em table

On the button with a playable hand, I raise to apply pressure on the blinds and take initiative preflop.

A3 offsuit is too weak to defend from the small blind against a button open with the big blind still behind.

62o is among the weakest hands; even getting 200 to win 650, it plays poorly out of position against a 3x button open.

T3 offsuit is too weak to open from the button in this setup; folding avoids dominated and reverse-implied-odds situations.

AQo is a strong hand for blind-vs-blind play, so I'm raising for value to 3bb from the small blind.

A3 suited on the button in a 3-handed game is a clear open-raise; 2.5bb puts pressure on the blinds.

Defend the big blind getting favorable pot odds with a suited/gapped-equivalent 97 offsuit against a button min-raise, especially heads-up after the small blind folds.

We have middle pair with modest kicker on an ace-high board. Checking controls the pot and lets the preflop raiser act.

Top pair with a weak kicker plus a gutshot wheel draw on a dry ace-high board; a small c-bet gets value from worse aces and 5x/9x hands while denying equity.

Call the small continuation bet with middle pair heads-up; folding would be too tight, while raising mostly gets called by better hands.

Our pair of nines has limited value on this ace-high board against the preflop raiser's continuing range. Checking keeps the pot controlled and preserves showdown value.

Top pair with a weak kicker is dominated by the better aces that call the flop, so checking back controls the pot. It also keeps worse hands like 9x and 5x in and avoids facing a check-raise.

We have two pair on an unpaired board and can extract value from many one-pair aces, queens, and stubborn nines. A moderate river bet targets those calls while limiting losses against stronger two-pair or sets.

Top pair with a weak kicker is getting about 3.9:1 odds against a half-pot river lead. The big blind's range still has enough bluffs, missed draws and worse pairs to make a call profitable, even though better aces are present.

K2o is a weak offsuit hand with poor postflop playability, and folding from the button costs nothing here. Calling or raising out of position relative to the preflop action is not worth the risk against two blinds.

Pocket eights are a strong heads-up blind-versus-blind holding and should be raised for value while denying equity.

A2o in the big blind against a small-blind open has plenty of equity at these pot odds, since I'm calling 200 to play for a 600 pot. I'll be in position postflop, so calling is fine, and a mixed 3-bet isn't necessary.

A small continuation bet on this dry high-card board pressures unpaired hands while risking little with our medium showdown value.

We are getting 5:1 on a small c-bet and will be in position for the rest of the hand. Ace-high with a backdoor nut-flush draw has enough equity against a wide small-bet range to continue.

With a medium pocket pair on a paired board, checking controls the pot and preserves showdown value. A turn bet is unlikely to get called by many worse hands while stronger Qx and Jx continue.

The SB checked the turn after c-betting the flop, which suggests weakness. Our calling range credibly holds Jx and Qx, so a roughly half-pot stab can fold out middle pairs and missed hands. Our ace-high has little value at showdown against the pairs that make up much of their range.

Pocket eights are a weak bluff-catcher on this paired, queen-high board after the preflop caller bets large when checked to. Folding avoids continuing against a range with many queens, jacks, and stronger pairs.

T9 suited is a strong, playable button opening hand with good postflop potential. Raising to 2.5bb applies pressure to the blinds while keeping the pot manageable.

52 suited out of the small blind facing a button open, with the big blind still left to act, is too weak to call or 3-bet profitably. Out of position, folding is the standard play.

K9o is playable against a button open, and I'm getting good pot odds to call only 150 more into a 400 pot.

I have only king-high with a backdoor flush draw on a paired board, so I take the free card and see what the preflop raiser does on the flop.

Betting our open-ended straight draw with two overcards to the board can fold out unpaired overcards and builds a pot when we improve.

We have only King-high with a flush draw, but we are out of position and the board is paired. The opponent's bet suggests strength, and calling would risk more chips on a draw that may not be profitable out of position.

JTs on the button in 3-handed play is a clear open-raise; a 2.5bb open applies pressure to the blinds while keeping the pot manageable.

Q2 offsuit is too weak to continue out of position against a preflop raise, so folding saves chips for a better spot.

King-deuce offsuit is too weak to defend against a button open at this sizing, especially out of position.
