Another ruthless beating!

[Nay Lin Tun]

I personally would like to attack the black's king side. Trade the blacks' light color bishop and then open the f- file. White also have an advanced pawn on e5 for king's side attack.

I also noticed this difference in depth. It indicates that clusters computing power (slow CPUs + overhead) is much lower then the power of Clemens's 16CPU machine. Of course assuming that depth shown by the cluster is comparable to R4.1 which is more then fair assumption.
They should really pull the plug on the cluster or update its software and hardware. The way it is now, it looks pretty close to being a scam.

... the cluster is really designed more for deep analysis for professionals or using its analysis capability to search several lines deep very quickly...

What you say applies for all good chess engines, both amateurs and pros know to use them well.
You should be ashamed for upcovering the poor play of the cluster machine, in such a foolish way.
This match prooves it is nothing more than a clay giant when confronted with Houdini3 on a 16 core machine.

Sincerely I cannot understand the move 19 Ra2; it is like Rybka didn't see the very simple Bxa3.

So strange.

The move Bxa3 is not that easy(for most engines). But with hindside we are always nearer to the truth. But for me what comes in mind first as almost begging for playing is b6, instead of Ra2.
I analysed the game under Fritz12 gui, with compare analysis giving Rybka 4.1 4 cores and 300 sec thinking time. Rybka than also came up with this line at depth 21. That seems pretty more even than the played Ra2?!
