I now gave them an additional Pawn odds for a new 400-game run. As predicted from the previous result, the Guanacas seem to be losing that substantially. I stopped the 2 Knights vs 2 Guanacas match after 300 gmes, with the Knights leading by 77.8%. Such an extremely unbalanced result cannot really tell me anything quatitative, So it makes no sense to try to reduce the error from 2.5% to 2%. In stead I started a match of 2 Knights vs 3 Alpacas, where I put the third Alpaca on d2,e2,d7 or e7, advancing the corresponding Pawn by 1 square. e.g. rnbqkbnr/pppppppp/8/8/8/4P3/PPPPAPPP/RABQKBAR w KQkq - 0 1 where A = Alpaca. This seems to go pretty even (but only 20 games so far, so can still easily be anything between 35% and 65%). I remember I did some divergent pieces sometime ago (in particular mNcK, mKcN, mQcN and mNcQ), and I thought I posted the rsults at CVP. But I don't remember where, and I cannot find it. What I recall was that mQcN was 450 and mNcQ 750, when N=325 and Q=950. I never did mQcK and mKcQ, but snce K and N are pretty close in value, one might expect nearly the same. Now R is about half a Q, and W is about half a K, so it does not seem that silly if mRcW would be about half a mQcK, which would be about equal to mQcN = 450. That would put mRcW around 225. Now the Guanaca is very similar to mRcW: its lacks the odd-stride distant non-captures, but as a compensation it jumps, and so it cannot be blocked on these odd-distance squares. So actually something around 225 would seem a quite reasonable value for something like the Guanaco. Edit Form You may not post a new comment, because ItemID MatsNewPieces does not match any item.
