Kibitzer's Corner
Apr-19-18  Marmot PFL: After this game Maurice Ashley pointed out 24...Nf5 to So, who said he didn't even think of it and that's why he was only number seven (in ratings). 25 ef5 Nd5 26 fg6+ fg6 and black threatens Bxa1 as well as Nxe3 Qxe3 Bd4. That's complicated though and what black plays is simple and effective enough, he makes the ending look very easy. White I think should not have allowed 26...Nc2.
Apr-19-18  Ulhumbrus: 21 Rf1?! displaces a defender of the c4 pawn. The result is that on 21...b5! White has to play 22 cxb5 and so in effect make the concession of exchanging the more valuable c4 pawn for the less valuable a6 pawn.

25..Nd7 offers a pawn on d6 which White cannot accept as on 26 Qxd6 Nc5 traps the queen and this suggests that So is in good form. The suggestion is wrong if that is how strongly So plays normally.

The sequence begun by 26...Nc2! ends up winning a pawn on a3.

32...h5 prepares to displace a defender of the e4 pawn and Black's pressure on the e4 pawn induces White to concede the bishop pair by 34 Bxc5 and then toe displace his e pawn by e5.

Apr-19-18  Zibbit: Interesting game! I like the early trap by Zerebukh....some interesting lines possible there! https://youtu.be/hMsF5LRTSnw

I am sure, though, Wesley is disappointed he didn't find 24...Nf5! However, from experience I know that he would feel 100 times worse if he didn't get a win, after not finding that line.

In my life I have studied at a minimum 17,000-18,000 tactical puzzles, and I didn't think of it either.

In chess, tactics are what separate the champs from the chumps.
