you can work around it with regex:

vb.net Code:
  1. Imports System.Text.RegularExpressions
  2.  
  3. Public Class Form1
  4.  
  5.     Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
  6.         Dim s As String = "tourney ffa team ctf ""clan arena"""
  7.         For Each str As String In Regex.Split(s, "(?<!""\w+?)\s(?!\w+?"")")
  8.             MsgBox(str.Replace("""", ""))
  9.         Next
  10.     End Sub
  11.  
  12. End Class
