Here's a sharp tactical game for anyone who wants to test their tactics. I'll present it in short but frequent bursts to give anyone interested a chance to practice some sharp analysis.
The game was not played be me, nor was it played on this site. More details may spoil some fun.
1.e4 c6 2.d4 d5 3.e5 Bf5 4.Nc3 Qb6
First exercise: now assess 5.Bd3
By-the-way, I don't claim that every question will have a single right answer. There will be equally good or better options to some of the moves I give.
