MASSIVE UPDATE: I decided to play around with this again today, and I found MAJOR improvmemts for the B to G file games. See if you can beat me! If not, give proof as to why my game is optimal (To Rubio and others: This edit is NOT deviating from the orginal goal of this question.) I shall post new links along with PGN text.

UPDATE #2: It’s all posted! Go ahead and take a look at it all! The beauty of chess!

The pattern for the numbers goes as such (how many moves it takes, that is currently known, to do the goal for each file):

A-31 B-17 C-13 D-13 E-13 F-13 G-17 H-33

Due to the symmentry here, I suspect that my mirror game for the H-File could be rearranged to be the same as the A-File game. But this hurts my brain too much. If you can do it, please try!

This is an old question with anwser to the optimal solution get 6 pawns on the A-File: Get 6 pawns in file A or H

Since I’m really into chess theory, I decided to find fastest solutions I could find for the rest of the files of a chess board, which is from B to H.

I’m posting links to my solutions here to see if anyone can find a faster way. If there is no faster way for a certain file, just simply make a brief statement of what is all optimal in your answer.

Found a faster way to get 6 pawns in the B-File than your 21 moves solution. This is probably not optimal though.


1. b4 c5 2. d4 cxb4 3. d5 e6 4. Nd2 exd5
5. Nc4 dxc4 6. Rb1 f6 7. Rb3 cxb3 8. Qd6 g6
9. Qc6 dxc6 10. e4 h6 11. Bb5 cxb5 12. Bb2 Kf7
13. a4 Kg7 14. e5 fxe5 15. Nf3 Kh7 16. Nd4 exd4
17. c3 dxc3 18. a5 cxb2 19. Ke2 Qb6 20. axb6 axb6

  • $\begingroup$ @RewanDemontay You can't mirror this on the G-File since it requires the queen sacrifice for black at the end and a for the queen to move through the d-file, which is closed if you mirror it $\endgroup$ – Embodiment of Ignorance Mar 30 '19 at 18:52
