Glaurung Mjolnir Re: Knight sac

Post by Eelco de Groot »

For Glaurung Mjolnir this is not immediately obvious, but for Rybka it isn't either 8-)

I've made a lot of builds because of some confusion about the King Safety calculations when there are no enemy Queens, so now already at Build 35. Build 24 was essentially the same but is a bit faster in nodes per second, probably because it skips some code that I added for blocked passed pawns later. Maybe I will remove it or I will have to think of something else. But there really is not that much changed from the standard Glaurung 080422, I would not know how for 97% of the code :roll: and it is already pretty good :)

Deep analysis with Build 24:

For Build 35 I have two versions of UCI settings, in Mjolnir 005 Tord's new Passed Pawn Extension finally seemed ready to switch on with one half ply, and there is now even more Razoring done with a Maximum Razoring Depth = 4 where in Mjolnir 004 the Maximum Razoring Depth = 3. Actually these are depths of 5 and 4 respectively compared to Glaurung 080420, because Tord secretly added a half ply internally. You better know! Sometimes it can be a close shave from falling off the horizon with these early jumps into Q-search.

With trusted Mjolnir 004 settings:

And with new Mjolnir 005 settings a little more 'Panache' is added but really not that much is different which is probably just as well:

The danger here is "will it stick with it?" The score dropped significantly at depth=15, which might mean it will switch with more time to something else..

I feel stupid looking at this position, because I would have captured the pawn and then the knight. I have not looked into why my idea does not work yet, but OTB, that would definitely be how I would have played it.
