let us solve chess with 7 piece odds

I have no doubt that theoretical value of chess is draw. but I wanted to do something different. I have adjusted the following position into droidfish 7:

If black has no any piece, I think 1.e4 is better than 1.d4. we have to release queen and bishop as early as we can.

I played white against Droidfish and mated in 18. May be faster mate was possible

well, go on please.

After this position we will add King's bishop.

then queen's bishop, then King's knight then queen's knight. COntrary to the endgames table base, we will start with the starting position. If experts do this they can have fast advancement in their works.

This is a really fun idea, I'll start now.

You would be very surprised with how many positive changes you can make in your life, if you can make it your top priority to mind your own business.

do you really think that asking him the question you asked was sometihng instead of nothing?

LoL

I have droidfish only which can not solve the thing I set.

I have one more idea:

when things will get difficult for engine we will remove a pawn or two. for ex: if engine can not solve when we are pursuing King+Bishops+knight, we will remove a pawn or two. like this:

if engines can not solve this, we shall remove a pawn from A7 or H7

I think anything above 1 or 2 major pieces of black is not solvable in reasonable time.

Ruhubelent,  can you give the original source you referred to ?

after this question, I googled the source I read it in many ways. I did not find the original one I read but I found this one: on wiki someone says he tried it with Houdini and Houdini took 5.5 hours, he claims to have found forced mate in 22 against King+Queen+Queen's bishop. It would be very great if he shared the line, I would try it with Droidfish.

I can not install stockfish into my windows 10. can someone explain me how to do it?

it would be great if Komodo owners too join us.

Houdini users would also be welcomed.

I think even though Stockfish seems to defeat the two engines they are better calculators than Stockfish. IN some puzzles I saw Stockfish fails to find the answer while Komodo/Houdini can solve it. but now I have no any engine on my computer. I have droidfish only in my phone.

thanks dude. I am gonna try this. 

what OS do you use? I use windows 10 and can not install stockfish. can you mail me the file of the stockfish so that I can use and search it so that we can get faster?

I think this may be the reason we need Komodo or Houdini. at the time I reached the 13th move, I thought there must be better moves than 13 Qc5 and the other engine approved it. let us compare it:

Could be..
