Advantages and disadvantages

Haas's mood is very uncomfortable. The ACE ball has been challenged successfully by Zhang Guan for two consecutive times, which is a great blow to Haas in morale. Fortunately, the referee decided to let him serve again, so Haas still had two opportunities to serve.

"How did it happen, such a slight gap, even the Hawk-Eye system also needs to be enlarged to see clearly that it is an out-of-bounds ball, Zhang Guan even directly challenged it, so surely, he sees clearly that it is an out-of-bounds, does he have a super vision?" Haas shook his head unclearly, looked at the field in front, and began to hesitate to serve to the original landing point.

"Come on again! I don't believe it can go out of bounds again!" Haas flicked the ball and snorted. The tennis ball immediately flew out but was blocked by the net. Haas made a mistake this time and did not cross the net.

"The strength is a little worse." Haas shrugged his shoulders angrily. He felt that he had been affected by the previous two challenges, resulting in a deviation in the strength control.

For a mistake, Haas started his second serve. Compared to the first serve, Haas must be more conservative. The ball speed is about 20 kilometers slower than the first serve. The landing point is not very limited but he enhanced the rotation of the ball.

"Drink!" Haas yelled to boost his morale. The opposite Zhang Guan also relied on his ability to move and ran to a more suitable catching position.

"Zhang Guan's forehand! Is it a topspin or a side spin?" Haas saw Zhang Guan using his forehand to receive the ball and immediately became alert. He also knew Zhang Guan's forehand before the game, knowing that he might play something like Nadal's high spin ball.

However, Zhang Guan did not choose to spin up, nor did he choose to spin sideways. Instead, he hit a diagonal line with a forehand straight shot, and the position of the drop point was selected at the sideline.

"What? Zhang Guan received the ball directly back to the diagonal sideline. How could he make this choice!" Zhang Guan's serve was greatly unexpected by Haas. He was caught off guard and hurried toward the catch point.

Zhang Guan's choice is very unreasonable behavior in professional tennis. In the face of a second serve that is not very powerful, the best choice for the receiver is to seek stability, first to stabilize the situation, and then find the opportunity to fight back. Receiving the ball and directly adjusting the diagonal line is very difficult. Secondly, the turnover rate is extremely high. It has always been considered a very hard play. Players often use this style of play because their disadvantages are already so great that they fight for a goal. But now the game only came to the second game, Zhang Guan also kept his serve, so Haas would never expect Zhang Guan to catch the ball and directly hit it to the diagonal sideline.

Haas did not catch up with the ball, and the ball also fell within the boundary, the score came to 30-15.

"He was attacked by Zhang Guan. His luck on this ball was not bad. It didn't go out of bounds. The next ball still needs to be strengthened!"

Haas continued to serve while thinking, but the quality of the ball was still very good, but Zhang Guan still successfully received the ball, but the quality of the ball was more general, and there was an opportunity to get on the net.

Haas didn't choose to play before the net. He was a player with a predominantly bottom line and a very comprehensive player. Playing in front of the net was still a little too risky for Haas. Haas and Federer are very similar, not very sure of the opportunity before the net, so it is not easy to try the net serve.

Haas forcibly retaliated with a forehand and directly attacked Zhang Guan's backhand. Zhang Guan also responded with a backhand that was still vigorous.

"Sure enough, as expected before the game, although Zhang Guan is a one-handed backhand, his strength is close to the backhand shot of ordinary players. It seems that it is still the right choice to fight backhand against him!" In the past, it was found out that the opposite Zhang Guan had a very limited return.

The ball hit the inner edge of the sideline, Haas saved the ball thrillingly but allowed Zhang Guan to go before the net. Zhang Guan was not as cautious as Haas. He chose to be in front of the net without hesitation and scored again, the score came to 30-30.

The next ball, Zhang Guan still chose a marginal return point, the result was that he returned the ball towards the out of bounds, the score came to 40-30.

For the next goal, Zhang Guan made the same choice. The referee awarded the ball as the inbound ball, and Haas failed to challenge and the two sides evenly divided.

Immediately after Haas served and scored, Haas took the lead.

Zhang Guan then returned the ball out of bounds, Haas also kept his serve.

...

After the two games, the score of the first set of the two sides reached a 1-1 draw, and the game entered a short rest period.

Haas wiped the sweat from his head, drank some water, and then began to recall the previous two games.

"Whether it is serving or receiving, the choice of placement is very hard. Zhang Guan chose this extreme play, which is really beyond my expectations. But his luck is also really good, especially in the first game. All three challenges have been successful. If there weren't the three challenges, I should have been leading 2-0 now!"

"This style of play is too hard for luck, it is impossible to put every ball on the line! And also consider the factors of the referee. Always playing this limited ball, the chance of the referee's misjudgment will increase a lot, although there is a Hawk-Eye challenge, you can infinitely use the Hawk-Eye. If you fail once, you will have one less chance. Even if it is dragged to a tie-break, it will only be an extra challenge opportunity. I really don't understand, Zhang Guan's technique is very obviously not bad, but why does he choose such a fight? If he continues to play like this, I will win!"

On the other side, Zhang Guan also recalled the situation of the two sets just now and summed up his gains and losses.

"The odds of the referee's misjudgment are still quite high today. Thanks to the Hawk-eye system, otherwise the first game might have been judged to be my loss. I think maybe even the referee is a little bit unsuited to the Hawkeye system. The number of times the challenge has been restrictions does not matter to me. I am 100% sure I can challenge to succeed, but it is different for Haas."

Zhang Guan glanced at Haas secretly and then thought, "For Haas, there is one less chance every time a challenge fails. Now the first set game has only been played for two games, and there is still a long way. Now for both of us, it is still a balance of power. We can challenge the referee's misjudgment by challenging the Hawk-Eye, but once one of the challenge opportunities is used up, the balance of power is equivalent to being broken."

"So, we will continue to fight like this until I have exhausted the number of challenges of Haas! At that time, it will be the 'cross-point' where our strengths and weaknesses changes!"
