WHY STUDIES? My fascination for studies proved highly beneficial, it assisted the development of my aesthetic understanding of chess, and improved my endgame play. - Vasily Smyslov.

Consider the following gem:           Paul Keres, 1936 In this position Black threatens 1...b2+. The plausible try 1.Qb8 does not help. So what can White do? 1.Nc2+!! Now 1...Bxc2 is met by 2.Qb8. After 2...b2+ White wins the bishop. Or 2...Bb1 3.Qxb3 Ba2 4.Qxc3+ Black is mated. 1...Ka2 2.Nb4+ 2...Ka3 leads to a spectacular display by White. 3.Nd3! Bxd3 4.Qd6+ Ka2 (hoping for 5.Qxd3?? b2+) 5.Qd5!! pinning the pawn on b3 and threatening 6.Qa5 mate wins. 2...Ka1 3.Qa2+!! bxa2 4.Nc6! 1-0           Black is helpless against the threat of Nd4 and mate with Nb3 or Nc2 next move. 36 | P a g e Solutions: Are you a problem Solver?
