I can play best on single table. If i play on two or more tables at the same time ,I lose more often. Because I lose my temper some time when I lose a big hand to a poker donk and that affects on my game on other tables also. So I like to play on single table only.Or in simple words losing on one table can affect your game on other tables also. So I advise others also to play on single table. You can concentrate better on your game and strategies .As for me, I can only play up to 6 tables. If I play more, I lose concentration and eventually go bust. How do you guys handle 20+ tables at a time? Is there a secret?
