After the conclusion of the (unsuccessful) Science Park open, I present you 4 interesting positions from my games. Note this are not tactic problems, but real life positions, so your goal is to find the best move, its follow-up, and the ideas behind it. I recommend spending between 10 and 20 minutes per problem, enjoy!
Problem 1: Joris Kokje vs Francisco Hernández
Black has sacrificed an exchange but white queen is trapped. How should black continue?
Problem 2: Francisco Hernández vs Dirk Floor
White is two pawns up but his kingside is weak. What is the best continuation?
Problem 3: Francisco Hernández vs Ferdinand Binnendijk
Black is underdeveloped and has just played f4, opening the position. Punish it!
Problem 4: Francisco Hernández vs Peter Mijnheer
White has sacrified a piece for the attack, how should he continue? Warning: this is a very difficult problem with only one winning, computeresque move.
In the game I played the inferior 1. Bxd6 and was lucky to scape with a draw.
