   FrogC has kibitzed 160 times to chessgames   [less...]
   Jan-05-21 A H Williams vs C F Morris, 2015
FrogC: 17.Ne4 wouldn't work for White because after 17...Qxe1 18.Nxf6+ Kg7 the knight will fall after the queen is recaptured. Hence the clever 17. f5!, luring away the g6 pawn. Now the knight can get away to h5 with a second check, and if the king follows it by Kg6 then it reaches safety on

FrogC: Thanks very much, that makes more sense.
   Sep-30-19 Paulsen vs Anderssen, 1876 (replies)
FrogC: I've just had a league game as White in this unusual line of the Vienna. I played 6.d3, which must be inferior to Paulsen's 6.d4, but won anyway. I found the opening intriguing, and it's an honour to be following in the footsteps of two such legendary players.
   Sep-02-19 I A Horowitz vs NN, 1940 (replies)
FrogC: I play this line as White. 4.Qg4 Qf6? is a trap I've won quite a few games with. But I've never found the sort of sacs Horowitz comes up with in this game.
   Aug-30-19 Egor Filipets vs A Aleksandrov, 2018 (replies)
FrogC: I got a Friday puzzle! Well, almost. I didn't look hard enough at White's defences after declining the sac.
   Aug-28-19 McShane vs Efimov, 2009 (replies)
FrogC: Easiest puzzle of the week so far.
   Aug-27-19 Karpov vs Salov, 1993 (replies)
FrogC: This is hard to see. I kept looking for action down the f-file, missing the switch to the h-file.
   Jul-02-19 P Ricardi vs J Arnason, 1984 (replies)
FrogC: This is the hardest "easy" puzzle I've ever seen. Black has seven possible checks, all of which have to be looked at, all of which can be escaped in at least two ways. When those are dismissed, you have to look at ways of restricting the flight squares for one of the checks. I looked ...
   Apr-26-19 U Fataliyeva vs O Girya, 2019
FrogC: What a wild game!
   Jan-29-19 Bagirov vs Kholmov, 1961 (replies)
FrogC: This does seem to be Tuesday level to me. It's an unusual tactic, but possible to get there with a bit of logical thinking, and no long variations to calculate.
