Strange Material Balances?

Sort:
arceus2010

I just wanted to look at some fun endgames, but all the popular ones (such as Queen vs. Rook or Minor Piece vs. Pawn or something like that) are already in thousands of textbooks! So I wanted some new material balances - that you guys get to make all by yourselves! So far, I've made up a few myself - such as two bishops and knight vs rook! So I guess I've said it all -- go make material balances in the comments!

Thats a material imbalance, and a win for black no matter who is to move.

True, (and i admit i should have written "imbalance") but if you were Black, could you make a win?

So basically you are asking us to put pictures of any possible positions on this thread?

Are you thinking of something like this? I believe it was a 90/30 game. There probably isn't much quality chess here... None of white or black was interested in a draw.

I've had queen & rook v. 2 rooks & knight come up a bunch of times lately.  The three pieces have yet to be beaten in this combo (I've been on both sides of it).

@ Taskinen

 

No i am looking for endgames with few pieces on the board that u think one side can win

The position I originally used in this post is now analysed more closely in my blog: Adventures in endgame tablebases.

Rocky64, exactly post stuff like that! Also, do you know any good tablebases? The one you used, by the way, was Queen and Knight vs. Bishop, Knight, and Rook.

You could also put two engines up against each other in the position and see how they play.

The Lomonosov tablebases cover all possible positions with 7 units or fewer and so is the best. AFAIK, the only way to access it for free is through an Android app. Check their site for details: http://tb7.chessok.com/

For positions with 6 units or fewer, you can access the Nalimov tablebases for free here: http://www.k4it.de/index.php?lang=en&topic=egtb

It looked like a total crush for White, but for some reason, most of the moves were draws!!! Any ideas why?!!

Rocky64

That's a position where White has mate-in-67, but start the R on b1 instead, say, and it's a draw. So yes, it's bizarre but typically so for tablebase results and not really possible to understand. Still, you can play through some of the drawing lines and get some ideas of how Black does it.

I luckily found an online tablebase!!

That's a draw according to the tablebases, but some WK-moves allow Black to win. The most interesting case occurs after 1.Kh2, when Black has only one precise way to win and hence it works as a puzzle. The sequence is quite short too and understandable! So, how can Black win the WQ?

this one was actually one of my own games - https://www.chess.com/live/game/2996063212 checking and protecting is a endgame essential for getting positional chess advantages .

Nice to see some games being posted around. But here is a challenge: Find the longest endgame with 7 pieces or less where one side can actively win!
