plz help wid this tic tac toe code

im writin a tic tac toe code..bt theres is a problem my code cannot decide who the winner is ....i have checked the code and there seems to be nutthing wrong wid it any help is welcome
i am posting the code below:

Code:

#include<stdio.h>
#include<conio.h>

void main ()
{
int go=0;
int i =0;
int player;
int row=0;
int column=0;
int winner=0;
int line=0;
char board[3][3]={
		   {'1','2','3'},
		   {'4','5','6'},
		   {'7','8','9'}
		 };


 printf("\n\n");
 printf("%c| %c| %c| \n", board[0][0],board[0][1],board[0][2]);
 printf("---|---|--- |\n");
 printf("%c| %c| %c| \n", board[1][1],board[1][2],board[1][3]);
 printf("---|---|--- |\n");
 printf("%c| %c| %c| \n", board[2][1],board[2][2],board[2][3]);




 for(i=0;i<9;i++)
 {

player=(i%2)+1;

 printf("hi player %d please indicate position where u want 2 place %c \n", player,(player==1)?'x':'o');
 scanf("%d",&go);
 row=--go/3;
 column=go%3;




 board[row][column]=(player==1)? 'x':'o';

printf("\n\n");
  printf("%c| %c| %c| \n", board[0][0],board[0][1],board[0][2]);
  printf("---|---|---| \n");
  printf("%c| %c| %c| \n", board[1][0],board[1][1],board[1][2]);
  printf("---|---|---| \n");
  printf("%c| %c| %c| \n", board[2][0],board[2][1],board[2][2]);
  printf("---|---|---| \n");
    scanf("%d", board[row++][column++]);
}


if(i<9);
{
goto chk;
chk:
{
//this is the part where winner has to be decided and where the problem is its not working//

 if((board[0][0]==board[1][1]&& board[0][0]==board[2][2])||  
   (board[0][2]==board[1][1]&& board[0][2]==board[2][0]))
winner=player;

 }

{
   for(line=0;line<=2;line++)
 if((board[line][0]==board[line][1]&& board[line][0]==board[line][2])||
   (board[0][line]==board[1][line]&& board[0][line]==board[2][line]))
   winner=player;

}
if((board[0][0]==board[1][0]&&board[0][0]==board[2][0])||
   (board[0][1]==board[1][1]&&board[0][1]==board[2][1])||
   (board[0][2]==board[1][2]&&board[0][2]==board[2][2]))
   winner=player;
}


 printf("player%dwins\n",winner);
}

Code:

if(i<9);
{
goto chk;
chk:
{

That probably takes the prize for todays most pointless piece of code. What do you actually expect this to do? [What it actually does is: It checks if i is less than 9, if so do nothing (as there is a semicolon immediately after the i), then start a new block, which contains a goto to the immediately following label]. Removing that (and the corresponding end brace) will change NOTHING of what the code actually does.

Right now you'll say that the player wins, even if the computer wins, since that's what player always is. Once you find three-in-a-row, you'll have to figure out whether it's three X or three O.
