Beware of organizing pawns
(Excuse me for my english. I use google translator and please take into consideration, that I write from the perspective of a player with elo 1700. My observations may not always be correct.)
For those who learn chess basic principles I want to show what to watch out for. If is in game exchange figures, is need to think ahead, what position will then be pawns. When they are pawns in a row, it's like they were just one. I used this principle in the following game, which I then quickly won.
