help in checkers game

[m0bb1n]

Hello,

I am currently making a checkers game and need some help on labeling the 3rd row different numbers than the first. At the moment it prints this out:
R2 R4 R6 R8
R1 R3 R5 R7
R2 R4 R6 R8

How do I make the 3rd row, R9 R10 R11 R12? The part that assigns that is here.

//puts all RED PIECES DOWN
    int piece=0;
    for(int row=0; row<8; row++)
    {
        int& piece=piece;
        piece++;
        std::string tempPiece=std::to_string(piece);
        for(int col=0; col<3; col++)
        {

            if (row%2==1)
            {
                if(col%2==0)
                {
                        playboard[col][row]="R"+tempPiece;
                }
            }
            if (row%2==0)
            {
                if (col%2==1)
                {

                playboard[col][row]="R"+tempPiece;
                }

            }
        }


AND BELOW IS THE FULL CODE TO TEST

THANKS IN ADVANCE! 

#include <iostream>
#include <algorithm>
#include <ctime>
using namespace std;

//bool checkAlive(char )

{
    //sets up all the spaces
    for(int i=0; i<8; i++)
    {
        for(int j=0; j<8; j++)
        {
            playboard[i][j]="  ";
        }
    }

    //puts all RED PIECES DOWN
    int piece=0;
    for(int row=0; row<8; row++)
    {
        int& piece=piece;
        piece++;
        std::string tempPiece=std::to_string(piece);
        for(int col=0; col<3; col++)
        {

            if (row%2==1)
            {
                if(col%2==0)
                {
                        playboard[col][row]="R"+tempPiece;
                }
            }
            if (row%2==0)
            {
