When using the Cloud Engines on Playchess.com I experience Lag which sometimes will cost me a game or two at Blitz computer play.At LTC I imagine there won't be much of a problem.The problem could be with my local timestamp or connection.Has anyone experienced this problem while using the Cloud for blitz?

yes I had this kind of problem too. Playing blitz games is not good because you lost on time whatever the engine you booked on the cloud.

If that's with Rybka 4, try increasing "TC buffer", that way the engine will account for the lag and will play faster, avoiding losing on time.

no, it is with houdini 2.0c pro x64

My point is that if Houdini doesn't have a buffer option, you'd get a better performance with Rybka 4 than with it for Cloud games. If the engine you're using is unsuitable for what you are doing, switch to a better one!

Lag is something that can't be avoided over the internet, any kind of cloud implementation is going to have lag by force and people will have to learn to live with it. The only way to play blitz without losing on time will be to use an engine with time buffer feature.

Even if you managed to make lag match your ping (best case scenario) the engine will have less time that it thinks for the game and will play worse.

There must be some way around this by "tricking" the Cloud.The Time Buffer idea for Rybka would be an interesting try but what about the others?The faster you make Rybka play the weaker she becomes.

> The faster you make Rybka play the weaker she becomes.


You're not making it play faster, you're making it play at normal speed, currently, all engines are playing too slow due to lag.

Suppose the time control of the game is 3 minutes. Oh wait, it isn't! The engine is losing time per move, the real time of the game is 2 minutes 45 seconds because the lag will make the engine lose 15 seconds. The engine doesn't know this, and will play as if she had those extra 15 seconds. The engine is playing too slow. The buffer tells the engine the truth: "you have 2:45 for the entire game", now, the engine will play at normal speed for the time she really has. The current problem is that as lag isn't taken into account, the engine is being given false information about what time she has left, that's why you get loses on time.

>what about the others?


I don't know. I guess you could use a program like InBetween to intercept the commands that the GUI sends to the cloud engine, take the time left for the game and change it so it takes the lag into account, getting the engine to play at normal speed.

just increase your increment in games... That way you have time added back with every move.
Parent - By Uly (Gold) Date 2012-06-26 11:02
Still, the engine will play too slow and will have its time management fudged up. Suppose you get 4 seconds of lag, and 5 seconds increment. The engine is getting 1 second increment but being wrongly told she gets 5, the time management wrongly uses 5 instead of 1 in its calculation of how much it should take to move, and the engine will play weaker than another engine that used the time management correctly thanks to the time buffer.

Why play blitz with a cloud engine:eek:, makes no sense to me
Parent - - By Uly (Gold) Date 2012-06-25 23:32
Why not?
Parent - By Geomusic (*****) Date 2012-06-26 05:53
obviously for the reason previously discussed i.e. lag :)
Parent - By FWCC (***) Date 2012-06-26 02:12
The Cloud gives us many different engines on many platforms(various processors/cores,ram etc...) so playing at whatever TC one desires gives interesting results,minus the lag LOL.
