Hold'em table

T8o on the button 3-handed is a standard open; raise to 2.5bb to steal the blinds.

J8o is too weak to continue out of position against a button raise, especially with the big blind still to act.

Q8o is too weak to defend out of position against a 2.5bb button raise.

Button with an ace-high hand; raising to 250 takes initiative and may fold out blinds or isolate weaker hands, while still leaving room to fold to a 3-bet.

Folding JTo out of position in the small blind facing a button open.

Getting 150 into 400 with suited connectors against a button open, defending is clearly profitable. Calling keeps the pot manageable out of position.

98h on an A-J-2 board has no pair and no draw, and the ace-high flop favors the preflop raiser's range. Checking to the raiser out of position is standard; I can give up to a c-bet.

I flopped top pair with position on a coordinated board, so betting for value and to charge flush/straight draws is best. Checking would let weaker draws realize equity too cheaply.

With 98h on a J-A-2 two-tone board, I have no pair and no draw, only a gutshot-less backdoor, so I can't call a 400-chip c-bet into 550 profitably. Folding is the right play.

K3o is too weak to profitably open from the button, even in 3-handed play.

In a blind-vs-blind spot, JTo is a solid hand for a small-blind open. Raising to 3bb applies pressure and takes the initiative.

With 3c6s out of position against a small-blind raise, folding avoids playing a very weak hand for 200 more chips.

T8o on the button in 3-handed play is a standard open; a 2.5x raise to steal the blinds.

AJo is a strong 3-bet candidate from the small blind against a wide button open; raising to 900 applies pressure and takes initiative.

Holding Ten-Three offsuit in the big blind facing a raise and a 3-bet is an easy fold.

T8o facing a small-blind 3-bet: calling 650 into 1250 out of position-adjusted ranges is marginal and T8o plays poorly against a 3-bet range. Folding is the disciplined play.

J4o is a weak offsuit hand and calling 100 chips from the button invites blind completions or raises; folding avoids playing a marginal hand out of position postflop.

A7o is a solid hand to open-raise blind vs blind after the button folds. Raising to 300 exerts pressure and takes initiative.

A8o is well ahead of a wide blind-vs-blind SB raising range, and we have position and 3:1 pot odds, so calling is clearly profitable. Three-betting is also reasonable, but calling keeps their dominated hands and bluffs in the pot.

Out of position with Ace-high and no direct draw on a dry board, checking to control pot size and realize showdown value.

The SB raiser checked a dry, low board, which signals weakness. A small one-third-pot stab with ace-high can win the pot right away, and the hand keeps backdoor wheel and ace outs if called.

Facing a flop stab out of position with just Ace-high and no strong backdoors, folding is the disciplined play to avoid compounding mistakes on later streets.

J2o is too weak to open even from the button in a 3-handed game. Folding is standard.

Getting 3:1 to complete from the small blind against one player; 94o has enough raw equity to limp cheaply rather than fold or bloat the pot out of position.

With 4-2 offsuit and no call required, checking preserves chips and sees a free flop; raising with trash risks unnecessary chips.

A 9-high hand with only a backdoor flush draw on KQ7 is too weak to bet out of position into a big blind who checked a limped pot, so I'll check and see the turn cheaply.

With 4-high and no draw on a coordinated board, I have no value and no need to bluff into a caller; checking keeps the pot small and lets me see a free turn.

Both players checked the flop, which suggests weak ranges, so a small semi-bluff with a gutshot to the straight (any ten) can take down the pot often and still has equity when called.

I have 4-2 offsuit with no pair or draw on a Q-K-J-7 board, so calling a turn raise is not profitable.
