Kibitzer's Corner
Feb-04-13  jerseybob: Grefe's 4.f4!? is the kind of gambit one might expect from Denker himself. With 4..Qxf4 Denker says "Show Me" and Grefe says "I will". Not that this is a forced win for white; far from it. Black's defense seems suspect at several points, but defense was never what Arnold Denker was about.
Dec-24-13  DoctorD: From his Chess Tactician's Handbook:

"I had White and the game began 1. e4 c6 (the tactician's nemesis) 2. d3 d5 3 . Nd2 Qc7 I had actually been toying with this line in my pre-tournament preparation and couldn't resist the temptation to play the gambit idea I had come up with. 4. f4?!! It's probably completely unsound, but not totally ridiculous. After the further 4. .. Qxf4 5. Ngf3 Nf6 6. Nb3 Qc7 7. e5 I won rather easily and was awarded the prize for best-played game of Round One."

  OhioChessFan: 7...Ng4 deprived Black's LSB of its best square. I have to think 7...Ng8 was better.
Dec-26-13  jerseybob: OhioChessFan: A very Steinitzean suggestion, and maybe a dour defensive expert like Steinitz could pull it off, but the "un-dour" Denker?

  GrahamClayton: Both White's bishops capture a knight on h6 and a6 respectively.
Aug-07-19  sfm: 22.Qg8+! ends it instantly, instead of 22.Qxf7+?? Easy detail to miss. But there was no defense, also 20.-,Rb7 21.Ng6 is over. A very interesting and unusual game.

  An Englishman: Good Evening: After 40 years, still the only 4.f4!? in the database. Evidently everyone else considers it "completely unsound." On the other hand, it only had to work once.
Aug-07-19  Cheapo by the Dozen: If the engine is to be believed, 7 ... Ng8 leaves White with a little advantage, and so does 5 ... e4. Declining the gambit also doesn't look great. So if 4 f4 is unsound, I don't yet see why.
Aug-07-19  siggemannen: Today's pun makes yesterday's seem like a bad acid trip
Aug-07-19  Nosnibor: Denker came to grief by accepting Grefes gambited pawn.
Aug-07-19  areknames: I love 4.f4, what a wonderful move.
