Hold'em table

With the button folded, Q4 suited is worth completing heads-up from the small blind for the additional 50 chips.

A2o is well ahead of a small-blind limping range, so raising to 4bb for value and initiative is reasonable; checking is also fine, but a raise punishes the limp.

Q4 offsuit is too weak to defend against a 4x big-blind raise out of position.

A6 offsuit is a reasonable button opening hand three-handed, with positional advantage and ace blocker value. I use a small standard open size.

KJo plays well as a 3-bet from the SB against a wide 3-handed button open, avoiding a multiway pot out of position while taking initiative.

8-5 offsuit is too weak to continue facing a raise and a re-raise, and the pot odds do not justify calling out of position.

A6 offsuit is dominated too often against a small-blind 3-bet and lacks playability even in position. Folding preserves the stack.

On the button 3-handed, T6o is a reasonable steal with two players left to act; a small open pressures the blinds.

Q9 offsuit is too weak to continue out of position against a button raise, especially with the big blind still to act behind. Folding preserves chips for a better spot.

9-high offsuit is too weak to defend profitably against the button raise out of position.

On the button with a speculative hand, I raise to steal the blinds and take initiative while keeping position if called.

A2 offsuit is too weak to defend profitably from the small blind versus a button open with the big blind still to act.

Q9o in the big blind facing a 2.5x button open, getting 150 to win 400, is a clear defend against a wide button range; calling beats 3-betting with this hand.

Q-high on a paired board out of position against the preflop raiser; check and look for a cheap showdown or fold to heavy pressure.

C-bet with a gutshot and position to fold out overcards; if called I still have straight outs.

Getting better than 3:1 against a small c-bet on a dry paired board, Q9 has enough equity and overcard potential against a wide button range to continue.

Top pair with a weak kicker plays well as a check-call out of position. This lets the button keep bluffing while keeping the pot controlled against his stronger Qx hands.

I have only 6-high with a gutshot/straight draw, and the opponent called my flop bet, so checking to see the river for free is the safest play.

Top pair (queens with a 9 kicker) on a paired board is ahead of most of the button's turn check-back range, such as underpairs, 4x and ace-high. A roughly half-pot value bet should get called by worse hands.

I have only 6-high with no pair or draw, and the opponent's river bet indicates strength. Calling 550 chips with no made hand is clearly -EV, so I fold.

Q8 offsuit is a reasonable button open in three-handed play, leveraging position and initiative. I use a small opening size to risk little while pressuring the blinds.

98o out of position in the small blind against a button open, with the big blind still left to act, is a weak spot; folding is standard.

62 offsuit is far too weak to continue against a raise, and calling out of position with this hand has poor expected value.

K5 suited is a clear open from the button in 3-handed play, so I'm raising to 2.5bb to take the blinds or play in position.

T6s is suited and playable, and I'm getting good pot odds to call 200 into a 400 pot. Folding is too tight against a button open in 3-handed play.

7-3 suited is far too weak to defend against a button raise with a caller already in the pot.

I have no made hand and no real draw on this A-high flop, so I check to see what the preflop raiser does before investing any more chips.

The ace-high dry board favors my button opening range, and K5 with a backdoor diamond draw is a fine small c-bet against the small blind's check. A third-pot bet takes down the pot often.

I have only ten-high with no real draw on an ace-high board, and facing a preflop raiser's continuation bet, calling is not profitable. Folding preserves my stack.
