Solid Hardwood, Engineered and Laminate Flooring - Expansion Gap Question

I completed a 11x 12 room using Laminate flooring over concrete for my first project this weekend. I installed them with baseboards in place and covered the expansion gaps with shoes. I know this is amateur, but most installs in FL are done this way. I had some help from a friend who has done this project before. While installing I was really watching for expansion gaps. It seems like this is a key point to watch for. He had mentioned that since the baseboards flex in and out (which they do) the expansion gap was not that critical. Almost all my board have at least 1/4 expansion. Some have more, a couple have much less. It is necessary for me to cut a relief for those that are close? If so, which I dont mind doing, how can I cut them in place? I am not going to take up boards to to this. I would say there are about 3 boards that are pretty tight. If I could cut the plank, thus increasing the gap, I would be ok.

Is this necessary? If I wanted to be safe and do this, is there a tool I can use to cut back the plank from the baseboard easily?

Thanks in advance

I wouldn't take my advice & run with it since I'm no where NEAR as experienced as most of these guys but you could probably use an undercutting saw, the saw for cutting under door frames & such. Not to sure how well the edge you cut would look but your covering it with shoe anyways. Or you could use something like a rotozip probably!? Just a thought! Good luck with it!

Zoeyl may not be as experienced, but must have some knowledge because that was going to be my suggestion also. An electric undercut saw, only run it along the wall so it cuts the floor instead of running it along the floor so it cuts the base.

Thanks for the responses.

Smokey, I see that you are a very experienced installer.
Is it necessary to relieve those few planks?

Also, is there a preference on how to run the planks? I would like to send you a pic of the room and figure out if it is the best way lay the planks. My room is done, but I am concerned about an entry into the room. It is too difficult to describe and a pic would speak a thousand words
