Hold'em table

Q4 offsuit is a weak heads-up blind hand and does not justify completing from the small blind under this objective.

Raise the button with an ace in this short-handed configuration to capitalize on position and initiative.

KJo is well ahead of a wide 3-handed button opening range, and calling out of position with the big blind still to act is poor. A 3-bet to about 10.5bb takes initiative and isolates the opener.

Facing a raise and a reraise with 5-8 offsuit out of position, this hand is far too weak to continue for a large additional cost. Folding preserves chips for a better spot.

A6 offsuit is too weak to continue versus a large small-blind 3-bet after opening, especially at this sizing.

Three-handed on the button, T6o is at the edge of a wide stealing range, and position against the blinds makes a small open profitable.

Q9o is marginal but playable 3-handed, and I'm getting good pot odds to call the small blind completion. I'll keep the pot small and see the flop out of position.

9-6 offsuit is too weak to defend against a button raise and small-blind call out of position.

We have no made hand and no draws on this flop, so checking is the best way to see the opponent's action and avoid committing chips with a weak hand.

Middle pair with a weak kicker on an ace-high board has showdown value but can't comfortably take a raise. Checking back in position controls the pot and keeps villain's bluffs in.

Second pair plus a diamond flush draw is a decent hand. The opponent's timed-out check suggests weakness, so a ~60% pot bet takes value and protection with equity if called.

Heads-up versus the big blind, As2c is strong enough to raise and apply pressure with positional initiative after the button folded.

Q9o in the big blind against a small-blind raise to 3bb is a clear defend. I'm getting 2:1 on the call, and the small blind's range is wide in a blind-vs-blind spot.

A small continuation bet leverages my preflop initiative on this paired board while risking little with ace-high and a club blocker.

The bet is small at a third of the pot, so we only need about 20% equity. Q-high with two overcard outs, plus position on a paired board, makes this a profitable float.

Ace-high retains useful showdown value against missed draws and weaker unpaired hands. Checking controls the pot on a paired board after the caller continued on the flop.

Top pair on a paired board after the preflop raiser checks the turn is likely best. A 60% pot bet gets value from weaker pairs and club draws while denying equity.

With only ace-high and no meaningful draw on this paired board, folding to the substantial turn bet is best.

Q8 offsuit is a marginal button opening hand in this short-handed spot; folding avoids entering with a dominated, disconnected holding.

The button folded, leaving a blind-vs-blind spot, and 98o is a clear open from the small blind. A 3x raise takes the initiative and can win the blinds right away.

I have 2d6c, a very weak hand, and face a raise to 300 with 200 to call. Folding preserves chips.

K5 suited is a clear opening hand from the button in 3-handed play. A 2.5bb open steals the blinds often and plays well in position.

7-3 suited is too weak to defend against a button raise, especially out of position heads-up.
