20 years older is an interesting talking point, if this was Boll Quek lost to (Boll who Apolonia beat recently by the way), would you say the same thing?
Let's review a list of Tiago's recent wins and losses: after his loss to El-Beiali of Egypt (who was showing special form that tournament beating Quadri as well), Tiago went to the European Teams and beat: Gionis, Majoros, Jancarik, and Boll, lost to Groth, was awarded a default vs Lind. In Bundesliga, he beat Robles, Duda, Mladenovic, lost a Chinese player and Calderano. Also lost to Kallberg in Muscat.
I wouldn't consider Quek better than Duda, Robles or Boll, I am saying that Quek at 17 I believe will continue to get better and better and has his best days ahead of him - he is capable of top 20 play on some days for sure, but he isn't there yet. I don't treat these kids as adults. Maybe my model is a mistake in that regard, but that is how I think.
