It’s important to be careful when advancing pawns because unlike other pieces they are unable to retreat. As they are also largely responsible for the defence of their king such advances tend to lead to issues over king safety.
In the first game on the following video Anatoly Karpov quite uncharacteristically moves all his pawns forward and might well have lost had Garry Kasparov not offered a draw.
I was in Lyons for the open tournament at the time of this match so it brings back some memories. Especially about the weather as it was freezing cold!
