Position of the day

Analyzing my own games, I found this interesting position from my game against the Grandmaster Stefan Djuric (Serbia) that we played in the second round of an Open in Nebrodi, Sicily. White has been pressing through the entire game, but I tried to make things as difficult as possible for him. My last move 33…Ra4! is threatening to trade his active rook and ease the pressure on my king. There is plenty to analyze here, if you enjoy studying puzzles or solving middlegame problems here is one for you:

TS1 (2)

White to play, find the strongest continuation:

Solution will be posted in a few days. Feel free to comment your thoughts.

Endgame Puzzle

Today I won this position with the black pieces. At first sight it looks like black is winning, but white has an incredible resource. Can you find it?

Astazi am castigat cu negru pozitia din diagrama de mai jos. La prima vedere, pare ca pozitia negrului este castigata, insa albul are o resursa incredibila pentru a se apara. O puteti gasi?


1. Rf6! In order to save the game, white needs to keep the black king cut and advance the passed pawn. 1… a4  2. e6 – a3  3. e7 – a2  4. Ra6! A nice little tactical trick to force the draw.

1. Tf6! Pentru a salva partida, albul trebuie sa tina regele negru taiat si sa isi avanseze propriul pion liber. 1… a4  2. e6 – a3  3. e7 – a2  4. Ta6! O importanta resursa tactica ce forteaza remiza.Read more
