I think better was 37.R1xe2 Nxe2 38.Nd3 Rxf3 39.gxf3 Nd4 40.Ne1! to prevent Nc2! [because 40.Re3? Nc2! looks bad for white] 40...f4! 41.Rd5 Re8!, etc.

Pono fights back to near equality but the connected 'a' and 'b' pawns will win Chuky the game.

Not a good opening choice from Ponomariov. All chess programs go in favour of black after 13 Nxe6. Mainline is 13 h4

<<<<37.Rxf5?? A terrible blunder, but if Ponomariov didn't see the Nd3 idea after 37.R1xe2 he might have felt that it was just a matter of choosing one losing move rather than another.>>> It's surprising that Ponomariov didn't manage to find the right move, as he had five and a half minutes left (to reach move 40, plus 30-second increments) after Ivanchuk's 36th move, and he only spent one minute before taking on f5. <<<[37.R1xe2! was a must. After 37...Nxe2 White has the nice resource 38.Nd3! , allowing him to reach an ending that's still defensible after 38...Rxf3 39.gxf3 Nd4 40.Ne1>>> From here, one plausible continuation is 40...f4 41.Rd5 Re8 42.Rxd4 Rxe1 43.Rb4 Re3 44.Rxb5 Rxf3 45.Rb4 Rxa3 46.Rxf4 , which is drawn.; Note, however, that 37.R1xe2! Nxe2 38.Rxe2? loses, as we already saw in our look at 36...Ne2: 38...Rgxg2+ 39.Bxg2 Rxe2 is the same position as above, with the same evaluation: Black wins the a-pawn and the game.; 37.Bc6 isn't as good as 37.R1xe2, but it's a lot better than taking on f5. 37...Ne4! 38.Rg1 Bf1 39.Re8 Rxe8 (39...Rfxg2+?? 40.Rxg2 Bxg2 41.Rxg8+ Kxg8 42.Kxg2 ) 40.Bxe8 f4 41.Bc6 Ng3 keeps White in a terrible tangle, and the win must be a matter of time.]>

Is that them-those big, clunky thingies that sit skulking in the corners?
