Hold'em table

Six-seven offsuit on the button is too weak to open profitably in a 3-handed 100bb spot without reads, and limping behind just builds a pot out of position-equity. Folding preserves chips for better spots.

Button folded, so this is heads-up versus the big blind with A7o. A small raise builds the pot with a playable ace and takes the initiative.

A8o has strong equity against a wide small blind opening range and we have position postflop, making calling the standard defense.

I have ace-high with no pair or draw on a paired king flop, and the preflop caller’s range includes many kings. Checking is better than bluffing into that range.

Checking back with Ace-high and the nut flush draw backdoor to control pot size and realize equity in position.

Ace-high with no pair or draw has little value on a paired-king board, so I check rather than bluff into the big blind.

I have Ace-high with the nut flush draw and position; checking behind takes a free card to realize my equity and keep worse hands in.

Ace-high with only the board pair of kings is too weak to value-bet, and a bluff is unlikely to fold out better kickers or made hands after two streets of checks. Checking realizes the showdown.

I hold a pair of kings with an ace kicker on the paired board; checking behind realizes showdown value against missed broadways.

J4o is too weak to open even on the button; folding avoids a dominated, poorly connected hand against two opponents.

J4o is too weak to complete or raise blind vs blind out of position.

86o is too weak to open profitably even on the button in 3-handed play.

95o is a weak hand even heads-up; folding the SB loses only the 50 already posted and avoids playing out of position with a dominated hand.

KQs is a strong suited broadway hand from the button; a standard 3x open builds the pot with position and applies pressure on both blinds.

K2o is too weak to continue against a button open; folding avoids a dominated, poorly playable hand out of position.

Q5o is too weak to defend out of position against a 3bb button open.

Pocket threes are ahead of most button opening ranges, so I raise to 2.5bb to build the pot and take the initiative rather than flat-calling.

Holding T6 offsuit in the small blind facing a button open is an easy fold out of position.

42o is far too weak to open even from the button in 3-handed play.
