 | | nasmichael: In terms of attacking squares, I particularly like this game as I play through it onscreen. I also set it up on the board in my study, and I think I like it even better! |

 | | Gottschalk: What's wrong 14...cxb5?After 13 d5 Nxd5 16.Rad1 N4f6 Black seems solid, despite the delicate situation of the king. |
|
| Jul-28-14 | | smitten: <What's wrong with 14...cxb5?> I haven't calculated it in depth, but 15.♕xb5+ followed by 16.♘c6+ seems good for White. |
|
| Jul-28-14 | | smitten: And if 15..♘c6 White can play 16.d5 I guess? |
|
| Jul-28-14 | | Once: A nice attack and somehow fitting that Euwe feints towards the colle opening (which wasn't really popular at the time that this game was played). Fritzie doesn't know why black didn't play 14...cxb5 either. Presumably Euwe's idea is that it would deprive the black king of the right to castle. But Fritzie sees nothing wrong with the move for black, with an evaluation of a little under -1. This may be a case of psychology. Euwe might have decided that he wanted to attack Colle's king even if it meant playing slightly dubious or speculative moves. He might have thought that Colle was a better attacker than a defender. Sobering to think that Colle died at the age of just 34. |

| Jul-28-14 | | Cheapo by the Dozen: I had the same thought as <Once> re the opening. Playing the ... Nc6 line seems like an extreme way to avoid the Colle system. |

| Jul-28-14 | | Cheapo by the Dozen: I'm not seeing a refutation to 14 ... cxb5 either.
I presume White's best is
14 ... cxb5
15 Qxb5+ Kd8
16 Nxc4
because he can't maintain the e5 knight easily, the c file could be helpful, and the pawn grab narrows the material gap. But his attack seems pretty slow after that. |

| Jul-28-14 | | Karposian: <Cheapo by the Dozen> <I had the same thought as <Once> re the opening. Playing the ... Nc6 line seems like an extreme way to avoid the Colle system.> But this is not the Colle System! In the Colle System White temporarily closes in his DSB by playing an early e3. What Euwe is playing here is in fact the London System, characterized by an early Bishop exit to f4 thus getting his Bishop out before playing e3. |

| Jul-28-14 | | AvidChessMan: <What's wrong with 14...cxb5?> After 15 Qxc5+, black has nothing to block check and must move the king. Black thought it better to protect against the knight fork at c7. |

| Jul-28-14 | | sneaky pete: After 14... cxb5 15.Qxb5+ Kd8 16.d5 .. Kmoch gives two lines, probably based on notes by Euwe: a) 16... Nxd5 17.Rfd1 Nef6 18.Nc6+ Kc8 19.Qa6+ ..
click for larger viewand White wins, writes Kmoch. In this line 18... Ke8 may be better, when 19.Nb4+ regains the Knight, but Black can still struggle. b) 16... Qe8 17.Nc6+ Nxc6 18.dxc6 Bd6 19.Rfd1 Kc7 20.Bxd6+ Nxd6 21.Rxd6 Kxd6 22.Rd1+ .. 
click for larger viewand in all variations White gets the Queen for 2 Rooks, with good winning chances because he keeps the attack going, writes Kmoch. Here the ancient Chinese proverb "long variation, wrong variation" pops up in my head. Black seems just too co-operative in this line. Kmoch questionmarks 14... Nxd5 and writes that black should have played 14... cxb5 anyway. |

game one was on April 4th, game 8 on April 11th. |

| | Stonehenge: This is the third game, it was played at the fifth, just like the second game. |
|
| Jul-28-14 | | WDenayer: It is very sad that Colle had such serious problems with his health, otherwise he could have been what is now called an elite grandmaster, one of the very best in the world, he certainly had this potential. On the other hand, it is remarkable to see how slow theory developed in those days. Even in 1930, in the famous game with O'Hanlon, Colle still played 8.Re1. We know better now. Colle played much better games than this eye catcher. Just imagine he would have played better openings. |

| Jul-29-14 | | Moszkowski012273: <sneaky pete> I don't see the black queen leaving the board in your variation "b" at all... |
|
| Jul-29-14 | | sneaky pete: <Moszkowski012273> Neither do I, but I think Kmoch is at least partly right in his assumptions. However, some of Black's moves leading to the position given in the second diagram of my post may not be besr. For instance, I cannot find a clear refutation of 17... Kc8 or 17... Nxc6 18.dxc6 Bc5. Affer 22.Rd1+ ..
click for larger view22... Ke7 seems best. 22... Kc7 23.Rd7+ .. forces Black to give up the Queen immediately and 22... Ke6 23.Qxc4+ .. is just foolishness and probably losing. Her is a line that dates from the Han Kmo dynasty and was dug up recently: 22... Ke7 23.Qb4+ Kf6 24.Rd6+ Kg5 25.f4+ Kh5 26.g4+ Kxg4 27.Qe1 f6 28.Qg3+ Kh5 29.Qh3+ Kg6 30.Qg2+ Kf7 (Han Kmo says: only sissies draw, Queen must go) 31.Rd7+ Qxd7+ 32.cxd7 ..
