Dices tips

If the number of the dice is equal or bigger than the number of the row (see 1) that your stone (2) is located you take off. If the dice number is smaller than the row number you must play that number by moving your stone towards rows with smaller number.  
  
(1) Row: the space, the slot, the field... that you play or place your stones. 24 rows exist on the backgammon board.  
  
(2) Stone: the stone, the piece... that you play on the board. There are 15 stones for each player. 
  
It may seem to be complex. It's not. To start to take off you should enter all your stones into your "home area" and in your "home area" you have 6 rows. Let's put a number to each of these 6 rows. The first one is "r1" which is also the row that your opponent's 2 stones are placed on the beginning of the game. Then you have "r2", "r3", "r4", "r5" lined side by side and the last one is "r6" in which you place 5 stones on the beginning. The row number is a number between 1 and 6. Same as the dice number. 
  
Use your real backgammon board and simulate those possibilities - Let's say you have one stone in row 5 and one stone in row 2 and you have rolled a "6 + 3", 6 is bigger than 5 and 3 is bigger than 2, and you take off your two stones. 
  
Suppose you have 2 stones in "r4" and one stone in "r1", you have rolled a "4 + 3", you take off one stone from "r4" with your dice number 4, and for dice number 3 you must move one stone from "r4" to "r1". 
  
You have 3 stones in "r6" and 2 stones in "r3", 4 stones in "r2" and 3 stones in "r1". You have rolled a "5 + 4". Unfortunately you will move 2 stones from "r6" to "r2" and "r1", and you can not take any stone off. 
  
You have 3 stones in "r6", 3 in "r5", 2 in "r4", 4 in "r2" and 3 in "r1", and you have rolled a "double3", because your "r3" is empty you must move 2 stones from "r6" to "r3" and take 2 stones off from "r3". 
  
You have 3 stones in "r3", 4 stones in "r2" and 5 stones in "r1", you have rolled a "5 + 4". You will take 2 stones off from "r3". 
  
You have 2 stones in "r6", 4 stones in "r5", 1 stone in "r4", 3 stones in "r3", 3 stones in "r2" and 2 stones in "r1". You have rolled a "double4". You will take 1 stone off from "r4", move 2 stones from "r6" to "r2" and 1 stone from "r5" to "r1". Only one stone to take off. 
  
the worst position perhaps is when you have only two stones remaining in "r2" and you roll one dice a "1", for example a "3 + 1". While 3 is bigger than "r2", 1 is smaller, and you will take one stone off but move the last one to "r1" and wait for the next hand.
