Chaining pair of Promises

I'm trying to chain a some pairs of requests:

I search for game A (http request), Then I'm updating it's X to Y.

I search for game B, Then update it's property Z.

I search for game A (again), But the search result is already evaluated, before my update. So, I'm trying to update it's Y property, which is not there.

In terms of promises I want something like: A - Am --then-- B - Bm --then-- C - Cm

but my requests look like: A - B -> C --then-- Am - Bm - Cm

How this should be done correctly?

var requests =[];
matches.forEach(function(match) {

  var matchPromise = new Promise(function(mResolve, mReject) {
    var gamePromise = new Promise(function(resolve, reject) {
      GameService.find(token, id, function(err, game) {
        //this is a callback of an http request
        resolve(game);
      }
                       });

      gamePromise.then(function(game) {
        //irrelevant logic here
        GameService.matchUpdate(token, id, mId, function(err, results) {
          resolve();
        })
      }
                       });
      requests.push(matchPromise);

    });

    Q.all(requests).then(function() {
      return res.json({"status": "OK"});
    });
