White to move and draw. See if you can solve it without computer assistance. Have fun! 🙂
1. Re6 Qxe6 2. Nc5+ draw!
1. Re6 Qxe6 2. Nc5+ DRAW!
Let’s see how many fall for the wrong idea again by ignoring the legality of moves.
Remember this a few months ago.
1.Nd4!!!
>A-1…..Bxd4.2.Ra3+.Kb5/7.3.Rb3! Forces exchange of Q for R and it is a draw!
>B-1…..Qxd4.2.Ra3+.Kb5.3.Rb3+.Kc4.4.Rc3+. And black king cannot escape checks. If 4….Kd5.5.Rd3!!!.Qxd3. (Forced else 5.Rxd4 and it is a draw).Stalemate and draw!
>C-1….Q Along 6th rank.2.Re6 exchanges Q for R and draw.
>D-1….Q along b file.Qb5/7/8. 2.Ra3+ and 3.Rb3 forcing exchange of Q as in A for a draw
>E-1….Qa5/7.2.Ra3+/ exchanges Q for a draw
>F-1….Qc5/7.2.Ra3+.Kc6.3.Rb3+ and black cannot escape perpetual checks.if ultimately black king goes to c8/c7/c5.then Rc3! Exchanges Q for R and it is a draw.
>G-1…Qd8.2.Ra3+ Rb3+ etc for a perpetual. From b file black king can escape to d file only through –
>>a-b4-c4-d5 but at Kb4 itself Nc6+ forks And exchanges Q for a white win!
>>b-c5-d5 but at Kc5 itself Ne6+ forks and wins Q for a white win!
>>c-c7-d7 etc but at Kc7, Ne6+ forks and exchanges Q followed by Rb8+ winning the bishop and the game for white!
>>d-c8-d7 etc but at Kc8 comes Rb8+.Kxb8.Nc6+ forking and exchanging Q for a draw!

1.Nd4!Qd42.Ra3kb53.Rb3 Kc4 4.Rc3 Kd5 5.Rd3 Qd3 Draw
Nd4 draws if black takes it, not worked out if black has other options that win though. e.g. 1. Nd4 Qxd4 2. Ra3+ Kb6 3. Rb3+ Kc6 4 Rc3+ Kd6 5. Rd3 Qxd3 stalemate. Bxd4 falls to Ra3 followed by Rb3. However perhaps Black can keep the game alive with 1… QC5 or Qd8 so I may have the wrong solution 🙂
1. Nd4 draws if black takes it but uncertain if black has options through 1..Qc5 or 1..Qd8
1. Nd4! threats: Re6 or Ra3+ and Rb3,winning the Queen and therefor securing the draw. Taking with the bishop aswell as any king move will finally lead to the pin on the b-file, most queen-moves lead to a pin on a, b or c-file – or on the 6th rank. Left are
a)1. … Qd8 then rook checks on a-, b- and c-files force the black king either to a square where the knight has a fork on c6 – or to c8, when Rb8+ prepares this fork again.
b)1. …Qd4: 2.Ra3 Kb? 3.Rb3+ Kc? 4.Rc3+ Kd? 5.Rd3 Qd3: stalemate!
nice one!
More one fall, Re6 do not work.
1. Nd4 draws the game. If 1. Qd4 2. Ra3+ Kb6 3. Rb3+ Kc5 4. Rc3+ any move by the King on d d file will result in stalemate due 5. Rd3 and if the Queen takes the took will be stalemate. If the Bishop takes the knight the rook will check on a3 and after Rb3 loses the queen and draws. While moving the queen along the 6 rank will lose the queen on Rd3. Moving the queen to c5 c7 and d8 also draws.

Deja vu! If Nc5+ had been legal, this would have been very easy.
1.Re6 doesn’t work because after 1…Qxe6 the white knight is pinned.
The real solution is a bit more subtle:
1.Nd4!
Threatens 2.Re6 as well as (after, say, 1…Bxd4) 2.Ra3+/Rb3(+), winning the queen.
The move also blocks the black bishop and makes the c3 square available to the rook.
The black queen has to leave the b-file and the 6th rank immediately.
I see the following possibilities:
A
1…Qxd4
2.Ra3+ Kb5
3.Rb3+ Kc5
4.Rc3+ Kd5 (otherwise white will give perpetual checks on a3, b3 and c3)
5.Rd3! Qxd3
stalemate
B
1…Qd8
2.Ra3+ Kb7 (the king is heading for the d-file, but on his way he must stay clear of the c5 and c7 squares because of Ne6+)
3.Rb3+ Kc8 (and now after 4.Rc3+ Kd7 black wins, but…)
4.Rb8+! followed by 5.Nc6+ draws
The most intriguing line for me; the collaboration between the rook and the knight is just beautiful.
C
After 1… Qc7/Qc5 white can give perpetual checks on a3 and b3; the king cannot cross the c-file because of Rc3
Hope I didn’t miss anything. 🙂
1. Nd4!
if QxN, then Rook checks on the 3rd rank till the Black King hides behind the Queen.
Then Rd3! Qxd3=stalemate
if BxN then Rook checks on the 3rd rank and Rb3 will trade the Rook for the Queen.
I think any other move by Black will also end in draw
