Hold'em table

On the button in 3-handed play, pocket eights is a strong value hand warranting a standard 2.5x open raise.

94o is a weak hand facing a 2.5bb raise from the button; folding is clearly best.

Big blind facing a 2.5x button open, we need to call 150 into a pot of 400. T6s is a profitable defend at these odds against a wide button range.

Top two pair on a draw-heavy board; I lead for value and protection rather than risk the button checking back and giving free cards to straight draws.

We have an underpair to the board plus a gutshot straight draw in position, getting over 2.5:1 pot odds against a donk bet.

Top two pair plus a flush draw on a draw-heavy board. Betting about two-thirds pot gets value from tens, overpairs and draws while denying equity.

Villain has donk-bet the flop and fired a substantial second barrel on the turn; with second pair and no spade redraw on a coordinated board, folding is the disciplined play.

42 offsuit is the worst hand; folding preflop from the button is clearly best.

Blind vs blind, Q4o is a reasonable open from the SB against a single opponent. Raising to 3bb applies pressure and takes the initiative.

Holding pocket Kings in the big blind against a small blind open is a standard 3-bet for value.

Q4 offsuit is too weak to continue against a big blind 3-bet, especially out of position. Calling 600 more into a 1800 pot without a playable hand loses money.

62o is too weak to open from the button against two blinds at 100bb deep, so folding is the standard play.

Holding 64 offsuit out of position against the big blind is an easy fold preflop.

Q4o is too weak to open even on the button in 3-handed play.

Blind vs blind with Q4o, which has enough equity and fold equity to open from the small blind against a single opponent. A 3x raise pressures the big blind's wide range.

K7o is strong enough to defend in the big blind against a small blind open, getting 2:1 pot odds with in-position play postflop.

As the preflop raiser on a dry J-high board, I have the range advantage, so a small one-third-pot c-bet can fold out the big blind's many unpaired hands. My Q-high has little showdown value, which makes it a fine bluffing candidate.

I have King-high with no direct draw on a Jack-high board and cannot profitably continue against the continuation bet.

Q8o is a standard button open three-handed, with only the blinds left to act; a 2.5bb raise applies pressure and gives us position.

87s is a prime candidate to 3-bet from the small blind against a wide button opening range, gaining initiative and fold equity.

K3o is dominated against a raise and re-raise; calling 900 more with marginal equity is a clear fold.

Q8o is too weak to continue against a large SB 3-bet to 10bb. Calling 7.5bb into a 13.5bb pot with a dominated hand is unprofitable, even with position.
