When I started, I tried to play 2-3 tables at the same time, and there was one mistake: if there was any difficult situation in one, I thought, figs with him, I'll go to the end, I have one more, and in the other if then it did not go well, then with nothing remained, that ultimately on the
bankroll is adversely affected. Therefore, a beginner is better to play alone.
Now I play 2 simultaneously, maximum, very rarely, 3, only if very tasty. Attention is strongly dissipated. And if one ends, the next one does not start, I concentrate on the rest.
