Alekseenko, K. – Hasangatin, R.

2639 2018 · White wins (resignation, time or agreement)

A classical Scandinavian from 2018: Alekseenko (2639) against Hasangatin (2485), with 2...Qxd5 3.Nc3 Qd6 and quiet development on both sides. Accuracy was identical, 83% each, and the game stayed tense into the queen play. The first swing came with 34.Qe4+, flagged as a mistake yet shifting the evaluation from +0.5 to +2.3 for White. Black then let the game slip twice: 42...Qc4 turned -3.7 into 0.0, and 45...Rxa4 went from -0.2 to +5.5. The takeaway: a winning position does not hold itself, and two loose queen or rook moves are enough to hand everything back. 1-0.
