En passant bug in Komodo?

1.d4 d5 2.e4 fxe4 3.Nc3 Nf6 4.Bg5 Nc6 5.d5 Ne5 6.Qd4 Nf7 7.h4 e5?!

To me looks like dubious move. You just take on e6 en passant and whites (presumably bad position according to theory from 1990s) looks suddenly ok for white.

After 7..c6 - black is obviously much better.

I was hoping you were right so we could gain some elo points by a simple bugfix. But no, there is no bug. Komodo evaluates the endgame after the queen trade as equal, whereas it shows a tiny White plus after 7...c6. You say "black is obviously much better" but my database stats favor White as does Komodo, and it's not at all obvious to me which side is better.

Database with games of my teammember who managed to blow this a lot with black by blundering

Allowing the En Passant for sure is a very bad move. c6 really only move.

For sure some sort of hashing bug that only shows itself if you have tons of cores that already were searching. They do not know much about massive parallel correct search in computerchess.

It's clearly not a bug because if you search the positions after the queen trade and after 7...c6, Komodo marginally prefers the 7...e5 line. I'm not saying you are wrong about 7...c6 being the best move, but if so it means that Komodo's eval is a bit off in this particular situation; that isn't a bug.

Just got back from the pub so sorry for the late blitz final results

1. Jonny
2. Shredder
3. Komodo

Komodo third in a blitz tournament, behind Jonny and Shredder is not a thing you ll often see.

[lkaufman]

Well, behind Jonny was no disgrace, as it ran on fifty times as many cores, but behind Shredder was a surprise.

[JJJ]

So maybe the next Shredder will have a very big elo jump. I also see it played a very nice game against Komodo in this WCCC where Komodo was to me close to loose.

[mjlef]

Shredder is greatly improved since last year, and is running on a 32 core machine. It is showing a lot of depth and it is clear Stefan has made a lot of progress.

Jonny also is much stronger. For instance, it is currently in second place on the TCEC round 2. Johannes Zwanzger, Jonny's programmer, says its performance in WCCC and speedchess on the cluster depends a lot on how lucky it gets on its pondering choices. Jonny ponders on multiple opponents moves. So you can some games where it is amazing and others where it gets draws against probably weaker opponents. But the core program does look a lot stronger to me.

The Software Championship this weekend has everyone running on identical machines, whihc will take out the hardware components in WCCC. It should be very interesting. I am happy to see all this hard work by all of these authors.

Jonny is on second place because of luck, but of course, everyone sees it plays a lot stronger. Still , I feel Komodo is still the unchallenged number 1.

Just got back from the pub so sorry for the late blitz final results

1. Jonny
2. Shredder
3. Komodo
4. Hiarcs

Does HIARCS have a time management bug?

It seems to get short of time in most games (if the times are reported right) and has issues in the final phase. Not sure we're seeing HIARCS in its full glory.

Hans hard at work operating Hiarcs until we woke him up because he was snoring!
