Hold'em table

Q8o on the button in 3-handed play is a standard open; a 2.5bb raise pressures both blinds.

A♠J♥ is a strong three-handed hand, and a 3-bet can take initiative while charging the button and discouraging the big blind from entering. I choose a substantial out-of-position size against the 2.5bb open.

T6 offsuit is too weak to defend the big blind against a substantial three-bet, especially with the original raiser still to act.

Q8o is too weak to continue against a small-blind 3-bet to 8.5bb, even with position. Calling 6bb for a 12bb pot is dominated too often to be profitable.

Q7 offsuit is a reasonable button open three-handed; a small raise applies pressure to the blinds while keeping the pot manageable.

Q6 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act.

ATo in the big blind against a button 2.5x open is well ahead of the button's wide range, and calling 150 into a 400 pot is a clear continue. Flatting keeps dominated hands in, though a 3-bet would also be reasonable.

Ace-high with a backdoor nut flush draw on a K82 board that favors the button raiser. Checking to the aggressor is best out of position, and I can continue against a small c-bet.

A small continuation bet applies pressure on this dry king-high board, which favors my preflop raising range, while keeping the risk modest with Q-high.

Ace-high with a backdoor nut flush draw is getting great odds against a small c-bet (180 into 550) and is well ahead of the button's air. Calling keeps his bluffs in and lets us realize our equity.

With only ace-high and no real draw on this turn, I'm checking to see a free card or keep the pot small rather than bluffing into the preflop raiser.

I have only queen-high on a dry board and no meaningful draw. Checking takes a free card rather than bluffing into a player who already called my flop bet.

Second pair with an ace kicker has showdown value, but the flush got there on the river. Betting only gets called by better hands, so I'll check and look to call a reasonable bet.

Q-high has some showdown value against missed draws, while a river bluff is unlikely to fold many hands that called the flop. Check and avoid risking chips against the opponent’s likely pair-heavy range.

Q6 offsuit is playable as a button open three-handed. A small raise takes advantage of position without risking much.

Against a wide 3-handed button open, 76s is a good 3-bet candidate from the small blind. It has playability and fold equity, and a 3-bet is better than flatting out of position with the big blind still to act.

6♠2♦ is a very weak offsuit hand, and calling 850 against the raise would require far too much equity.

Q6 offsuit is too weak to continue against a large three-bet, even with position.

Three-handed on the button, suited hands like T2s are at the edge of a wide opening range. A small open to 2.5bb applies pressure on the blinds.

9♠8♣ is a weak offsuit hand from the small blind against a button raise, and the big blind still has a decision behind me. I fold rather than defend out of position.

A small pocket pair is worth defending against a button raise at this price, with potential to win a large pot when it flops a set.

My pocket deuces are an underpair on a connected, high-card flop. Checking avoids building a pot out of position with a weak hand.

The K-J-8 board favors the button raiser's range, so a small c-bet with T-high and backdoor straight equity should take the pot often against a big blind who checked.

Pocket deuces are unlikely to be ahead on this K-J-8 flop, and there are few good turn cards. Calling out of position against a continuation bet is not worth it.

T4 offsuit is too weak to continue from the button, especially with the small blind still to act. I fold rather than invest more chips with poor playability.

Q7 suited is strong enough to raise heads-up against the big blind, and a 3bb raise applies pressure while keeping the pot manageable.

T2o is too weak to defend against a 3x small-blind open. Calling means putting in 200 to win a 400 pot out of position with poor equity, so folding is best.

J5 suited is a playable button open three-handed. Raising to 2.5 big blinds uses position and gives the blinds a chance to fold.

T2 offsuit is far too weak to defend from the small blind against a button open, especially with the big blind still to act behind me.

Q5 offsuit is marginal, but the button’s small open and favorable pot odds make defending the big blind preferable to folding.

Top pair with a weak kicker has showdown value, but checking out of position controls the pot and lets the preflop raiser act.

With no pair, flush draw, or strong straight draw on this board, I prefer to take the free card in position rather than bluff into the big blind's continuing range.

I have top pair and can get value or protection from weaker pairs and draws after the flop checked through. A modest turn bet keeps the pot manageable with my weak kicker.

J-high has no meaningful draw on this turn. Calling the bet is unlikely to be profitable, and there is no strong reason to bluff-raise.
