Hiarcs 15.3

[Fran66]

Another detail I forgot: Deep Hiarcs 15.3 seems to have a hard time quitting in absurd positions. I just won a game (level 1600) with a rook +5 pawns against rook... five pawns ahead and he didn't give up, he kept playing until he received mate.

H15.2 is unchanged and there is no change in HCE Pro that I am aware of that could affect H15.2 play.

The Elos are calibrated and while their can be slight differences as the engine evolves it should not significantly affect chess strength. It maybe it is playing more book moves which could help it and you can change that by setting Limit Book Knowledge to true in the engine settings.

If you do not like H15.3 play you can switch to H15.2 which is unchanged.

I haven't touched anything in the book, I always leave it as it is by default. Is there any way to install the previous version of Chess Explorer?

Yes, if you want to downgrade you can download the previous version from the download page and install it.

Thanks, Mark. I just downloaded version 1.2.1 of Chess Explorer Pro. One more question: with this version, would it be possible to use the Deep Hiarcs 15.3 engine?

Best regards!

[Mark Uniacke]

Yes H15.3.1 is a UCI engines so will run in HCE Pro 1.2.1

[Fran66]

Thanks, I'll try it...

But I just realized that previously I was using 8 threads of my AMD 6800H and now only 4 threads. It seems contrary to all logic, but is it possible that with 4 the program plays stronger than with 8?

[Fran66]

Fantastic, I can beat him again.

Nice game.

[Fran66]

Thanks, Mark. Your program is fantastic, it's the best I've tried along with Shredder 12.


Best regards!

Just downloaded the latest version onto my MS Go tablet. I’m using HIARCs in analysis mode with a Millennium Tourney 55 via a USB cable.

Basically it was used during gameplay between two players at my chess club to “broadcast” the game.

It worked except it crashed intermittently closing HIARCs and of course losing the game. Don’t know if it’s because it’s on a tablet or if it’s because of the eboard.

Not sure if anybody else has experienced this.
