FATAL PIN

The Argentine Championships taking place right now. Position after 39 moves of play. What is there to say here? The Black Kingside is in shambles and, in chess, that is often all that matters!
WHITE TO PLAY AND WIN!

MISSED OPPORTUNITY

gm Valerga, Diego
Argentine Championships. Position after White’s 38th move. A crazy, chaotic struggle so far! Here Flores blundered with the seemingly strong 38…Ra-a2, overlooking that after 39.PxB! the White King is perfectly safe! White won on the 49th move.
HOWEVER, in the position above Black has a way to get a decisive advantage! Do you see the idea?
BLACK TO PLAY AND WIN!

Porto San Giorgio. Position after White’s 21st move (21.b3?) What to say? In a complicated position (with even chances) White overlooks Black’s threat!
