Opening Chess Problem (Ep#05): How to reach a position in 4

[SuperMyfamily01]

That is a frustrating problem!

1.e4 c6 2.Bb5 e6 3. Bxc6 dxc6 is the only one I can find...

Good puzzle. Now I will go watch some booty.

[MD3c0]

o damn i missed e6 forget my last comment haha

[MD3c0]

You could also solve the 4 mover with 1. e3 Nf3 2. Bb5 c6 3. Bxc6 dxc6 4. e4 Ng8

ow! i just kicked my knee on the desk

[mejnour]

Right!

[GoldeWC]

awesome, i couldn't solve it in one hour. Great puzzle.

[Fourpointo]

Doesn't 1. e4,e6(/c6) 2. Bc4,c6(/e6) 3. Bxe6,dxe6 also work for 3 moves?

[lachessleague]

That is true. However, the difficult problem is to do it in 4 moves.

[GreenCastleBlock]

Good job - you found the idea, and that's the hard part.

It's actually more efficient to shift the Rook to b8: 1.a4 Nc6 2.a5 Rb8 3.Ra4 Ra8 4.Rb4 Rb8 5.Rb6 axb6 5.a6 Na5 6.a7 Nc6 7.a8=R Na5 8.Ra7 Ra8 9.Ra6 Nc6 10.Ra1 Nb8

Nice. I remember when I first solved this puzzle. It is very difficult for most people to get.

See if you can solve this one. From the start position, remove both 'a' pawns and add a black pawn on b6. How is this position reached?

[lachessleague]

I love these types of problems.

Well, I came up with this solution. There is probably a much more elegant solution. But this is my first try.

1. a4 Nh6 2.Ra3 Ng8 3.Rb3 Nh6 4.Rb6 axb6 5.Nf3 Ra5 6.Ng1 Rb5 7.a5 Rc5 8.a6 Rb5 9.a7 Rc5 10.a8R Rb5 11.Ra1 Ng8 12.Ra2 Ra5 13.Ra1 Ra8

@GreenCastleBlock Cud u please message me and tell me how to do it, i can do it in 4 for white and 3 for black, but not 4 for both, i've been trying it for hours :(

[GreenCastleBlock]

@crazysaps Black can't castle in this position.
