I'm about 1500 on Lichess, and as white I almost always play the queens gambit accepted (if reached).
After some moves I often, almost naturally, play at some point Rfe1 and h3.
The first one is to get my rook away from the f pawn to a semi open file. The h3 push is because I'm always afraid of back rank mate so this prevents this. Also it stops black from playing bg4 pinning my usually unmoved queen.
Are these good reasonings/strategies?
