TCEC 10

[Nay Lin Tun]

I watched stockfish 8 vs stockfish 8 on my S7 edge handphone very often and noticed that Stockfish drew a lot of games with threefold repetition. May be a little bit randomness ( let say within 0.05 evaluation) might help to improve stockfish.

[Graham Banks]

Stockfish is drawing the weaker engines to much. It looks like there will be a new TCEC Champion this year.

Indeed - SF missed out this time.
Komodo v Houdini in the SuperFinal.

Also, a very nice showing by Fire 6.2 in Stage 2, the only other engine to finish above 50% in Stage 2 besides the Big 3.

[JJJ]

So I was right to hope for a Houdini / Komodo final this time. Now I would bet than Houdini is the slighty favorite here and says he will win with 52%.
I think contempt helped Komodo a lot but might be a little less strong in head to head, even if Houdini is not update. But I might be wrong if the next Komodo has won some more elo.

If so, I hope it will be a free upgrade for us H6 customers

[Jouni]

Stockfish is first engine, which goes WHOLE season UNBEATEN!! No word on that in chessdom page? In final Houdini is clear favorite. Komodo's win in stage 2 was position, which happens once in 1000 games.

[shrapnel]

+1. More than a slight favorite. These Long Games really suit Houdini and it is inherently the more aggressive Engine, updated or not.
Komodo, no doubt good, seems to get lost sometimes.
So, I confidently predict a Houdini win, but let's see.....

[Houdini]

It is, and Houdini 6.03 is already available to you - you can use the same download link we sent you by e-mail, it now refers to the updated version.

Houdini 6.03 corrects a stalemate bug which was reported to me this weekend. It occurs when there are white pawn captures available, for example this position:
[d]8/3R1pk1/5p1p/5PbK/B2p2PP/3P4/1r6/8 w - - 0 1

Try this position with the previous Houdini 6, set multi-PV to 4. You will get some surprising results .

The error was already present in Houdini 5, but apparently nobody has ever noticed it.
