1. Physcological effect? Let opponent level of guard drop.
2. See opponent down.(I heard from one player's comment, not mine. Don't tulan me...)
3. Due to work. (But Saturday he also late)
4. Just a bad habit.

I am sorry that my comment create such upset. My apology. I didn't know 几度 is a busy man as I saw his posting here quite often and had the impression he is quite free person.
I always have the impression that players should start the game on time, just like we must try to be on time for an important appointment. However I realised my comment to 几度 was unjustified. Yes, work is always more important then chess. Sorry, please accept my apology.

Actually I do not mean anyone playing kelong. I just had the impression that since 几度 have time to login and discuss in forum during day time and night time, then his workload be quite light and be able to reach the CC before 8. Then I heard some chess players talking about his predictable frequent late during competition, thats why I post my message in hope to understand the real situation. I regret my kapo-ness and my tone in the message is not polite.
I agree that there are always last minute work to do. Its just coincidence that 几度 got stuck in last minute work during the first 4 rounds. I also realised I have cause much distress to many forumers here. I wish to offer my apology again.

吴宗翰，卢国龙and黄俊铭 has tried their best in 7 rounds. I feel that we cannot blame opponents trying to play 平稳 with these strong players. There is one say, 先以不可胜，待敌之可胜(something like that, my chinese no good)。It is normal that in chess we 优势求胜，劣势求和，均势求机。It is no shame trying to draw stronger players. Ask any national players whether he tried drawing with China players when faced them?
I feel that the opponents have choosen good strategy. Don't forget, they are group A players and they know how to play checkmate too. It is a pity that 卢国龙and黄俊铭 did not make it to top 4. I believe they will play their best in the last two rounds for the sake of their supporters.

And they lost to players who really play fighting chess. Can see some openings are fighting at the edge of the cliff type.

there are people who bribe opponents during the last games of match to buy 乙级 or 甲级。That really turn me off. Can't they just play honourably and stop insulting chess.
