**poll question:**

what do you think will accrue if engine A & F have hundreds of matches when engine A (elo 4000), engine B (elo 3900) and engine F (elo 2000) are on the list; do you think engine A's elo will go up or remain same or go down when A & F have hundreds of matches and the result of A Vs. F is 200 wins, 1 loss and 10 draws for A? what's gonna be the ranking after hundreds of matches between A & F (if you know how elostats work and how the elo is calculated based on which formula, you know the answer); what's gonna be the order of engines (the ranking) from the strongest to the weakest? (I'll post the answer later, but we can find the answer before)

stockfish / 1 ply search

I found out a bug or a weird symptom for SF engines

when SF is fighting with other engines

I can pause the tourney in winboard

winboard 4.70 is convenient cuz I can pause the tourney anytime

to do something else

then when I continue (un-pause) the tourney

only SF's search depth becomes 1 ply

(only when I watch a movie or I do some other things

which are CPU or RAM intensive)

then SF loses

since it can only search 1 ply ahead

elostat can't run .doc file

I just saved a plethora of matches in .doc file

the elostat 1.3 in Arena couldn't calculate for the rating list

perhaps cuz of the format and added functions of .doc file

so I saved the pgn file with wordpad or notepad

which don't support the fancy functions

then now the elostat can run the pgn well

elostat

having matches with weak engines is not good

I found out something extroardinary about elo calculating

I think there are 2 prominent elo calculating methods

and for instance,

engines ------------------------- elo ratings

A ------------------------- 3500

B ------------------------- 3450

F ------------------------- 2600

if there are 3 engines with the repective elo ratings

currently A is the best

and B is only 50 elo behind A

and F is nowhere around A or B

what do you think will accrue if A & F have hundreds of matches?

some may think

since A will have 100 wins and 0 losses

along with 0 draws

(the actual result should be something similar

like 100 wins, 1 loss and 6 draws)

A can gain more elo

which will result in A having higher elo

some may think

no, that's not the case

since the elo diff between A & F is too large

so even if A wins hundreds of rounds over F

A can't gain elo

so A's elo will remain as it is

no elo change will occur

but the answer is actually A's elo went down a lot

so if the strong engine A fights many matches

with weak engines like F

A's elo goes down

that's what I found out

I heard bouquet is not based on ivanhoe

it is based on ippolit

that was recently on the nTCET chat box

and bouquet is fantastic!

it is on top of the tourney now!!!

opening book match(tourney)

I can't understand how opening book Vs. opening book tourney can be organized

book is something that is used by 2 engines

how one engine can use book A

while another engine can use book B?

moreover, how can we get one book is better than another book?

I don't understand how opening book tourney can be done

stronger opening book means the book only has the strongest openings hence little variety in openings?

weak opening book means the book has multifarious openings hence the book is good?

if engine A choses a move from book A

then engine B choses a move from book B

and then some

how can this go on?

how can 2 opening books fight with each other?

is it even possible?

I don't have any knowledge on this matter!
