  offramp: 15...♘xc1 looks like a terrible move! Why didn't Polugaevsky play the obvious 15...♘ce5?
Oct-17-04  weirdoid: <offramp> 15 ... Nce5 does not seem significantly better to me after, say, 16. Re3 (threatening 16. f4 Nxc1 17. fxe5). I think black will be forced to continue with 16 ... Nxc1 17. Rxe5 Nd3 (avoiding the horsie from getting trapped) 17. Re3 - not too bad really, but does not seem better than 15 ... Nxc1 directly IMHO.
Jan-25-09  sillybilly47: 15...NxC1 is very poor. Allows the Rook its freedom and makes White's task much easier. White bishop was an impediment in the position.
Oct-29-12  sagahelten: 15...Nxc1 is Fritz' preferred move. How can it be called a grave error? (0.11 vs. 0.17 after Nce5)
Oct-29-12  SimonWebbsTiger: Ray Keene, annotating in Informator 24/23 didn't think 15...Nxc1 was bad either. <saghalten> mentions the silicon gives +0.11, i.e. equality. That was Keene's appraisal of the position too. 20...Be7 deserved consideration and 24...Ra6 was an utter lemon. Just 24...Kb6=

  Dionysius1: And I'm sure Fritz and GM Keene are right. Nevertheless, exchanging an active knight for an undeveloped bishop seems strange (and didn't Kasparov say something about a position with a white knight on d6 or e6 pretty well wins itself?). So there must be a reason beyond that general principle (don't exchange your good pieces for bad)for their assessment?
Jun-15-14  Howard: Most of this game is annotated in detail in the excellent book Learn from the Legends.
Jun-15-16  ewan14: Was Lev's mistake 6 ... Ng4 ?
Aug-02-16  Howard: Not according to Marin---he felt that Black had a perfectly acceptable position after 12 moves...

...in contrast to Edmar Mednis, who stated in Chess Life and Review back in '77 that White had a "basically won" position after 12 moves, though he conceded that the win was not going to be easy.
