Hold'em table

J8o is slightly too weak to open profitably even on the button in 3-handed play.

Q2o is too weak to continue out of position against the big blind after the button folds. Folding avoids putting more chips in with a hand that plays poorly.

AKo is a premium hand on the button, so I open-raise to 3x rather than limp or fold.

52o is far too weak to call 250 more out of position against a 3x raise. Folding is the clear +EV play.

Getting over 2.25:1 pot odds in the big blind against a button open; QJo is strong enough to defend 3-handed.

Checking out of position to the preflop aggressor with backdoor draws and overcards.

I have top pair with the ace kicker on a checked flop and want value plus protection against the spade and straight draws. A roughly half-pot bet keeps worse kings and draws in while building the pot.

I only have Queen-high with backdoor draws out of position facing a continuation bet on a King-high board.

On the button with a suited hand and only 1bb invested so far, a small open pressures the blinds and can win the pot outright; 95s plays fine in position 3-handed if called.

8c 2c is far too weak to defend out of position against a 3x open from the button.

83s is too weak to continue out of position against a 3x button open; the extra 200 does not justify the poor playability.

54 offsuit is too weak to open even from the button in a 3-handed game.

43o is too weak to continue out of position against the big blind, so I fold rather than call or bluff-raise.

K7o is a standard button open in three-handed play; a small raise takes the initiative and can fold out worse hands before the flop.

9s6s is a weak hand facing a raise from the button; folding is the standard profitable play rather than defending out of position with a marginal suited connector.

In 3-handed play against a button open, A3o has sufficient equity and pot odds (calling 150 to win 400) to defend the big blind.

Flopped two pair out of position against the preflop raiser; checking to let the aggressor continuation bet.

I have only king-high with no draw, but as the preflop raiser facing a check on an ace-high board, a small continuation bet can fold out much of a wide big-blind calling range.

I flopped two pair on a draw-heavy board and want to build the pot while charging flush and straight draws.

King-high with no pair or draw has too little equity against a flop check-raise, and calling 500 does not justify continuing.

A8s on the button is a standard open-raise; I'll build the pot with position and fold out weaker aces.

K3s is too weak to defend out of position against a 3bb button open with the big blind still to act.

K7o is too weak to continue out of position against a button open; folding avoids dominated spots and poor reverse implied odds.
