Today’s 5-second tactics

Today’s examples come from the French Team Championship (Top-12) being held as I write in Saint-Quentin. The link is on the side-bar for those interested in finding out more. Other than that, solutions at the end below; more examples as the day progresses. GOOD LUCK!

Played on the 27th. Position after 15 moves. A rare case of a grandmaster being caught in a known opening trap! Black’s position looks solid enough (it is) but the theme of a discovered check is cleverly hidden from view…atleast from Black’s!
WHITE TO PLAY AND WIN!
