Tactics

Since it’s all about the chess… Here’s a little tactics practice…cool position worth a few minutes of your time.

Life Master Andrew Karklins, playing White, blundered with 24.Re3? I was Black, and managed to lose anyway (that’s not surprising, but the way it happened was shocking to me).

24.Re3? Ne5! 25.Nxe4!? and then what?

I did this without a board so I hope Im not off here.
25… Ng4 26. Rh3 Rfxe4 27. Qxe4 Nf2+ 28. Kg1 Nxh3+ 29. gxh3 Rxe4.
Did I get it right?

nvm, 26 g3 eliminates that. Back to the drawing board.

Actually in the case of 26. g3 Qh3 looks like it might work. Then 27. gxf4 Nxe3 28. Qd2 Rxe4 leaves black a piece ahead. If white doesn’t take f4 and prevents mate on f1 a different way, black can go ahead and take the knight it looks like, and pick up any spare material with Nf2+.

25…Ng4?? 26.g3?? Qh3! does indeed work. But I was planning 26…Nxe3!, which is even cleaner.

So I take it the ?? indicates Ng4 is not the correct continuation? Oh well I gave it a try :smiley: .

But you have found two important ideas that I didn’t sufficiently appreciate: mating threats on f1 and the idea of forking on g3. Keep pushing your analysis (I wish I had!): you’re almost at the main line AND the refutation of …Ng4?? (which, by the way, doesn’t lose–why?)

Haha alright I’ll keep looking. Still want to see if I can figure it out without using a board.

Okay 26.Nf6+ could be the refutation because Rxf6 27. Rxe8+ Kf7 fails to 28. g3 Qh3 29 Qe2 threatening mate at e6 so Rf2 wouldn’t be an option. If 28…Qxh2+, that fails to 29.Qxh2 Nxh2 30. Re2.

If 26. Nf6+ Nxf6 then 27. Rxe8+ Nxe8 then 28. g3

If 26… Qxf6 27. Rxe8+ Kf7 28. Qe2 Rf2 29. Qe6+ Qxe6 30. Rxe6 Rxb2 is losing for white so he could retreat his rook on e8 to e1 instead of Qe2.
28. Ree1 Nf2+ 29. Kg1 Bxe4 and now white has a tricky time getting out of this.

Based on that annoying discovered attack is 25…Ref8 the correct continuation?

So why weren’t you sitting next to me during the game?

Some of the variations need sprucing up, but you found both the refutation and the winning idea!

I can only be in so many places at once haha. Thanks, it wasn’t easy. Good puzzle definitely. I will probably come back and try to fix up the variations a bit later.

24.Re3? Ne5! 25.Nxe4!? Ref8! 26.g3 and now what?



Variation after 23.Re3 Ne5 24.Nxe4 Ref8 25.g3
Black to play and win

How many of you could have visualized this from 23…Ne5? I’m still having trouble believing it from this position!

Sorry I haven’t said anything in awhile. A friend moved in and I had to get them situated and I just had to get braces for the first time in my life because my teeth decided to move :frowning: so I’ve been busy. But I have been thinking about your problem.

I want to do 25…Rf1+ 26. Rxf1 Rxf1+ 27. Kg2 Ng4 but it seems like 28. Kxf1 Nxe3+ 29. Kg1 Nxc2 30. gxh4 Bxd4+ 31. Bxd4 Nxd4 leaves things relatively even, though I think black has an advantage at with casual inspection. Will look more when I have more time.

Black has a better move!

26…Ng4 27.gh Rf1+ 28.RxR RxR+ 29.Kg2 NxR+ will leave Black a rook up.
27. fg NxR and Black regains the pawn in what looks to be a better position. A sample line, 28. Qe2 QxP 29. Ng3 BxP.
27.Re2 Re1+ 28.RxR RxR+ 29.Kg2 QxhP+ 30.KxR Ne3+ 31.RxN QxQ and the bishop or rook is in trouble.
Maybe best is 27.Re1 Rf2 28.gh RxQ, with threats on the bishop, c-pawn and doubling on the 7th.

Beautiful, isn’t it? I stopped analyzing 25…Ref8 as soon as I saw 26.g3.

I stopped looking at 26… Ng4 after I saw gxf4. Good job martinak for finding the solution. Glad I didn’t have to do the whole thing myself :slight_smile: .
