Suggestion:
var count = 0;
var p1_placar = document.getElementById('placar1'),
    p2_placar = document.getElementById('placar2'),
    p1_jogada = document.getElementById('campojogada1'),
    p2_jogada = document.getElementById('campojogada2'),
    side = document.getElementById('side');
side.onclick = function(){
    executar1();
};
function executar1() {
    document.getElementById('conte').value = count;
    if (count % 2 == 0) jogarr(p1_jogada, p2_jogada, p1_placar);
    else jogarr(p2_jogada, p1_jogada, p2_placar);
}
function jogarr(jogad, jogad2, plac) {
    var girar06 = 1 + Math.round(Math.random() * 5);
    var imgs = new Array(null, "side1.png", "side2.png", "side3.png", "side4.png", "side5.png", "side6.png");
    var pontos = plac.value;
    for (i = 1; i <= 6; i++) {
        if (girar06 == i) side.src = imgs[i]
    }
    if (jogad.value == girar06) {
        pontos++;
        alert('Vc acertou');
    } else {
        alert('Você errou')
    }
    count++;
    jogad.disabled = true;
    jogad.style.backgroundColor = '#CCC';
    jogad.value = "";
    jogad2.disabled = false;
    jogad2.style.backgroundColor = '#fff';
    plac.value = pontos;
    return count;
} // end jogarr
What I have changed:
- I removed the function within the function
- onclick usage in Javascript instead of HTML
- reorganized the code to avoid equal line repeats within if/Else
- corrected the error I had when using plac = plac + 1;and how the variable has a different namep1_placarand/orp2_placarwere not updated.
Note: for this code to work on an HTML page you have to put an onload function, or put Javascript at the end of the HTML, before the tag </body>
							
							
						 
I edited the question to be readable, see if I guessed well what you meant.
