Daily checkmate - The power of the king

I solved today's 5 puzzles in 1 minute. In this one we can look the great cooperation of the king and rook. The idea of taking away squares instead of direct checks, sometimes we not attack the king, but we attack his available squares to force him to the mating square.

I plan to give checkmates. Again.

I am invited to play in an international master tourney in Budapest at the Hungarian chess federation. It will be a round-robin tourney of 9-11 rounds depending on the number of players. The tourney will start Saturday and we'll play a one round every day. My goal is to play my best chess. The instructive games will be analysed and and shared here. The time control will be 90 minutes/players plus 30 seconds per moves for 40 moves, then 30 minutes and 30 seconds/move for the rest of the game.
