I am a mathematician by profession, but kinda suck at chess. But I love playing with my son - even though since we bought a clock my record against him is 1W - 299L (or thereabouts, I've lost exact count).

My dearest chess moment is from one of the games against the kid. He was something like 7-8 years old at the time. I captured his queen, but exposed myself to a backrank mate while doing that. The look on his face when he reached for the rook, barely reaching across the table to the backrank to deliver the mate ... I will never forget that.

Oh, I'm the father of all the Switching Quylthulgs :-)

Skewbrow: Whire wins with 34.Kg3 for it threatens 35.Re5x. I see two ways to thwart the mate. A) 34.. Nd4 with a view of interposing 35.. Nf5+. But this fails against 35.h4+ as the black king is forced into either f5 or h5, when respective moves 35.Re5/Rh7 are mates. B) 34.. Rf8, again ...

Skewbrow: Happy to figure out that 29...Qb2 wins (rather than going for the back rank immediately). The only defence I had to think about a bit was the counter 30.Rc8, threatening mate, pinning the black rook (and leaving c1 covered in the continuation 30...Rxc8 31.Qxb2). But then, with the ...

Skewbrow: The first idea was 25.Rxd5+ cxd5 after which 26. Re6 would be mate if that square were not covered. The second idea was 25.Nxd5 cxd5 (again giving the white rook control of escape squares on the sixth rank) 26.f4+ which would also be mate if it weren't for the fact the pawn giving ...

Skewbrow: A lot of unprotected pieces. Most notably the black queen and the white rook on a1. I'm sure the combo 26.Rxg7+ Kxg7 27. Nf5+, exploiting the vulnerable stance of the black queen caught our eyes. Due to the presence of that hanging white rook I think we need to verify that not ...

Skewbrow: The black knight is pinned and only supported by the pawn g7. Furthermore, our bishop is aiming at h7. Let's add to the pressure with 30.Rf6. Black's options are: A) trade queen for a rook, B) 30..gxf6 31.Qxh6 and 32.Qh7x. C) Anything else with 31.Rxh6 and the same mate in 2 moves.

Skewbrow: I'm not sure about 26. hxg4 either. Surely the threat of bringing the black queen to the h-file is a big part of it. Black also needs to prevent white from bringing in reinforcements. May be 26..Qf4 27.Bh3 (otherwise ..Qh6+) Qf3+ 28. Bg2 (Qg2 Qxd1+) Qxg4. And now the threat of a ...

Skewbrow: The first thing I spotted is that 34. Nf5 gives an imposing mate threat, and defending it with gxf5 exposes the black queen. The second thing I noticed was the zwischenzug 34..Qb5+ saving the queen. Then it took a while to see that 35.(king move)gxf5 36.gxf5+ still leads to a quick

Skewbrow: The manouver 59...Rxb5 60.cxb5 a3. Stands out. The white rook is stuck. The black king has the time to snatch the b-pawn and march to b3 before the white king can help.
   Jan-25-19 D Perrett vs I Efimov, 2008
Skewbrow: PawnSac: In the variant where I suggested the manouver Q->f3->g4 mate, the queen starts from d3. How do I move her to g4 in one move??
   Dec-18-18 D Harika vs S Cua, 2008 (replies)
Skewbrow: After Qh6 only the rook move Rg8 protects the g7-square, but then Qxf6+ decides. Except that because Qh6 is not a check, black will defend with Qxf5 instead of covering g7. So let's divert the black queen first with Rxc5.
