Here is a way to get 18 queens, after that it's just a case of shielding the king with the new queens.
1. a4 a5
2. b4 c5
3. b5 d5
4. c4 d4
5. e4 e5
6. d3 b6
7. f4 f6
8. f5 g5
9. g4 h5
10. h3 h4
11. Nc3 dxc3
12. d4 Nc6
13. bxc6 b5
14. d5 b4
15. Ne2 Ba6
16. Ng3 hxg3
17. h4 Bb5
18. axb5 a4
19. h5 Ne7
20. Rh4 gxh4
21. g5 Ng6

Originally posted by stgrego78I think the reason some people think this is when you play OTB if nothing has been taken then you have nothing to use for the queen.
If my pawn reaches the other end of the board before there are any other pieces for me to recover, then I lose my queen, can I re activate her?
Also people I have played have expressed concern over my king having mutiple wives.
Here's a game with 5 queens (on the board at the same time). It was brilliantly contrived by Alekhine and never really existed. But he fooled many people into thinking it was an actual game. It is in Alekhine's "best game" collection.

There are many games with 4 queens, theoretically sound.
