I really don't understand about much "Lay"...Example: Germany - Mexico, i lay Mexico WIN with odds 100. If Mexico lose, i win? If they draw or win, i lose?
John,if you "lay" you are betting AGAINST a team.....so if you lay Mexico as per your example,should Mexico lose the game or tie the game you win your bet. If Mexico win,then you lose however much you staked against them.
If Mexico are 3.0 (equal to 2/1 in uk betting terms) you lose twice your stake if they win ,2 for every pound/euro/dollar/btc you "laid" them for, if mexico dont win you keep whatever stake you laid.
