39. Rh7+ |
? the smallest of errors, this move loses for white, and i didn't realise it for a few more moves yet. crucially, it is my king that wins, he is now free! | ||||||||
| | |||||||||
|
39... Kd6 |
<<<(Tugger) I must be honest, i didn't think you'd play that... the rook trade is now forced... you've allowed my king to escape, and your rook is attacked... the other options are... 40 Kh6/g6 Rxh7 41 Kxh7 and you're king has been forced back, a very expensive retreat... i will promote just before your king covers... 40 Rh6 Ke5 and the pawn is lost 40 Rh8 Ke5 41 Re8 Kd4 and the best you can do is advance, though it will soon enough come down to a rook sac to avoid you queening, then you have two linked pawns to worry about, your king too far away and your rook alone unable to deal with both... despite being a rook down, i will promote to win... if my pawns weren't linked, then different story... so you must trade or you'll lose... after that, well, you must be careful... i'm sure you can draw, but one bad move and it's lost... every move from now on must be correct...>>> see? even now i'm telling him he can draw. | ||||||||

40. Rxc7 |
indeed... 40. Rh6 Ke5 and the pawn is lost 40. Rh8 Ke5 41. Re8 Kd4 and he'll lose one of the pawns in the process of protecting the other... and moving the king to protect the rook is futile, since i'll just trade and force his king further from the action... | ||||||||
| | |||||||||
|
40... Kxc7 41. Kg4 |
this move is correct, in that it keeps him alive that little bit longer, and makes sure i earn the win...! | ||||||||
| | |||||||||
|
41... c5 |
off he goes... | ||||||||
| | |||||||||
|
42. Kf3 |
indeed... | ||||||||
| | |||||||||
|
42... c4 |
! of course, white cannot take the pawn or my b-pawn is unstoppable... | ||||||||
| | |||||||||
|
43. Ke2 c3 |
forced, any other move would gift the win to white | ||||||||
| | |||||||||
|
44. Kd1 Kd6 |
and now my king moves in... | ||||||||
| | |||||||||
|
45. Kc2 Ke5 46. Kd3 Kf4 |
! wins the pawn... of course, white cannot protect the pawn, or attack my b4 pawn, or c3 cannot be stopped... <<<(Tugger) So... the game... classic endgame... there is only one move you can make that will not lose... first, you cannot take my pawn at all... here the advantage of linked pawns at endgame is clear... you take my lower pawn and my other pawn runs off to promotion... that means you cannot protect your loose pawn either, as that would involve moving your king away from my pawn, resulting in unstoppable advance... you are in zugwzang... whatever move you make will be bad, so you must opt for the least damaging move... so your pawn is lost for nothing... but that does not mean you are going to lose... luckily, your blocking pawn is on the knight's file... this means there is only one way to your pawn for my king... note if your pawn were on the bishop's file, i would be able to bring my king around to your pawn via the rook file, but your pawn is stopping me from doing this... if the pawn were a bishop's pawn, then it would be a win for black... so, the only moves you can make to avoid promotion are either... Ke2 or Kc2... but Ke2 will lose too... why...? 47. Ke2? Kxe4 48. Kd1 Kd3 49. Kc1 c2! 50. Kb2 Kd2 and now the promotion square is covered... note when i advanced my pawn, i did NOT place you in check... this is the difference... the pawn forced your king OFF the promotion square... if i ckeck you when i advance, then you can move ONTO the promotion square... then the only square i can move my king to maintain support for the pawn is directly underneath on c3... but then what would you move if i played that...? the answer... nothing... it is stalemate... so... 47. Kc2! Kxe4 again, you need to be very careful... it is vital you do not allow my king to get on d2, as this will allow me to promote... and you need to make sure i do not advance my pawn UNLESS i ckeck you in the process, or else my king will get to d2... so again you have just one m | ||||||||

47. Ke2 |
as it happens, this was weak, but it didn't matter... i'd found the win... strongest was Kc2... 47. Kc2 Kxe4 48. Kc1! and it looks a draw... for instance, if play continues 48... Kd3? 49. Kd1! c2 50. Kc1 Kc3 stalemate or 48... Ke3 49. Kc2 and i can't get my king in... so, where is this win...? 48... c2! and this gives the black king a path to the pawn on b3... there is no need to explain the next moves, as they are the ones made... please continue... | ||||||||
| | |||||||||
|
47... Kxe4 |
and now i break it to him i've found the win... <<<(Tugger) I have found a win for me... i thought this was a draw due to your pawn being on the knight's file, but i am wrong... that means the rook trade was bad for you (though the actual trade was not the error, that was forced, it was checking me that was the mistake), as everything you did since then was correct, your king had to start moving... anyway, it doesn't matter, as here is a lovely endgame position for you to analyse and see just how strong linked pawns are in endgame... so... all moves will lose for you... 47. Kd4/c4 c2 and promotion wins or 47. Ke2 Kxe4 48. Kd1 Kd3 49. Kc1 c2! 50. Kb2 Kd2 51. Ka2 Kd1! and i will promote to queen with check... or, best chance of draw would be... 47. Kc2 Kxe4 48. Kc1... (this is best, see below) 48... c2! (the winning move) 49. Kxc2 (decline and i promote, forcing you to take) 49... Ke3 50. Kc1 Kd3 51. Kb2 Kd2 52. Kb1 Kc3 53. Ka2 Kc2 54. Ka1 Kxb3 55. Kb1 Kc3 56. Kc1 b3 57. Kb1 b2 58. Ka2 Kc2 59. Ka3 b1=Q and mate to follow and, the reason 48. Kc1 is best is because i will win quicker with other moves... 48. Kd1 Kd3 49. Kc1 c2! and i gain control of c1 or 48. Kb1 Kd3 49. Kc1 c2! and same again... . the one move i haven't spent a lot of time on is your remaining move... 47. e5 but after ... Kxe5 you're still no better off, you cannot stand still on c2...>>> | ||||||||
| | |||||||||
|
48. Kd1 c2+ |
! and here is the winning move... i could've played Kd3 first, that would've been a quicker win, but i wanted to demonstrate a pawn sac to win an endgame... and i didn't want the weak Ke2 to be the reason he lost... <<<(Tugger) I had two options here... Kd3 was one option, but i have gone for the more tactical c2!, as it is a perfect exapmle of a pawn sac winning an endgame... it will demonstrate the strength of the king in endgame... i feel there is a little more to learn this way... . how well do you finish your opponent off when you have a won game...? i assume you have no problems with Q vs K, or R vs K, but if you would like, i will be happy to continue to mate or at least mate next move before drawing this off and concluding our coaching game... i will promote to rook or queen, as you desire... otherwise, i will offer the draw after promotion...>>> | ||||||||
| | |||||||||
|
49. Kxc2 |
<<<(Taufiq) Most of the time, it's going pretty well to finish a won game with a Q or R, but if you want, you may allways show a little more details.. I'm curious how you're going to do this, with your blocked pawn...>>> | ||||||||
| | |||||||||
|
49... Ke3 |
<<<(tugger) we'll see when i get there then... now i need to force your king away from your pawn... there are stalemate traps i need to be careful of, i'll explain the main one when it comes to it...>>> | ||||||||
| | |||||||||
|
50. Kb2 Kd3 51. Kb1 |
<<<(taufiq) You got him..>>> | ||||||||
| | |||||||||
|
51... Kc3 52. Ka2 Kc2 |
and the pawn is lost... | ||||||||
| | |||||||||
|
53. Ka1 |
forced... | ||||||||
| | |||||||||
|
53... Kxb3 54. Kb1 |
again, forced... | ||||||||
| | |||||||||
|
54... Ka3 |
! Kc3 would've gained nothing, i would have had to triangulate my king to restore the position, then move to a3 anyway... 54... Kc3 55. Ka2! Kc2 56. Ka1 Kb3 Kb1 and we're back to square one... other moves would've allowed stalemate... <<<(Tugger) Kc3 achieves nothing, as Ka2 threatens stalemate... i would have to triangulate my king and bring it back to this position, and then go to a3...>>> | ||||||||
