Btw, my opponent actually lossed a tempo earlier on by moving his bishop out, I moved my queen to b3, threatening b2, and he moved his bishop back to protect it. So I guess technically two tempi. In this situation, was this exchange worth it?
No, your queen is now momentarily trapped, causing you to use precious moves or premature woodswaps. You have forced yourself into a middle game you aren't ready for. All for a crap knight and the a file pawn. Not worth it.
