Narrative:

In a busy pattern at eul with four fixed wing a/c [aircraft] in lh [left traffic] pattern for runway 12; and four helicopters in rh [right traffic] pattern for taxiway alpha (12). I radioed downwind; I radioed base and radioed final. Half-way down final my passenger observed an aircraft Y to our left on a very short base turning onto final. I radioed to say he had cut in front; but no reply. I continued briefly to see his next actions. He landed and I was forced to go around (radioed accordingly). My next approach; following an a/c on finals; and radioing per previously; an a/c taxied onto the runway immediately after the landing a/c touched down. He waited till the landing a/c had cleared and proceeded down the runway. I judged with him accelerating and me decelerating; we could just about make the landing; although it left little margin.
