Only use an Engine if you can NOT solve it !

What a fascinating coincidence.....

Could be a composition. Would be interested to see the complete game played online.

Who Played this game, it almost look like my games, and what time control those players used Rapid, standard time control, was it played by GM ( I doubt it ) or Novice players less than Master like us. How did White Queen got stuck on a3? completely out of place , you mentioned that this game was actually played online, so it must be played in the last 25 years with the introduction of this internet I would like to know all this questions How did White forced Black to get his pawns structure specially on the King side so similar to my pawns, How many moves was this game since I move my Queen several times after I saw the possibility of him and waiting for him weather to trade his Rooks which was the best move or place it on the d3 square

I finally found an engine that I can play even with specially during this time of Pandemic COVi19, but I will play a few more games since this little pearl of an engine keep my brain thinking, and I will figure out how to beat it

Never mind it seems to have been a glitch, I see it now on b3 ... somehow it did not show without several page refreshes. This is a simple tactic and would rate around 1400 to 1500 ELO on the chess.com tactics trainer as the pattern is very obvious. I think this type of tactic is never missed by any reasonably strong player even at bullet, but that doesn't mean that it can't be missed sometimes by even the top GM on earth . Chess blindness can sometimes be incredible ... I mean look Magnus Carlsen, by far the strongest player ever created by planet earth actually missed a completely winning simple tactic here. The thing is that MC was not the only strong player to miss it .. Aronian also missed it!

MC actually played Rxd4 ??? and ended up drawing the game.

I Just gave it to few of the players that I know on chess.com who are rated average around 1850 and told them to solve it by using a chess clock with 30 seconds, out of 10 players only 2 solved it without using any engine , but you simply did not see it until you used your engine, since this position has been here for at least 8 hours, which does NOT need page refreshes, anyway since only two who tried to solve it honestly and solved it, tell me that this tactical puzzle is rated for club players around 1850 to 1950.

But with your position, there is NO tactical shot, all that is required is to know what piece to move or take with, Black simply has to play Rxd3 and Black is winning immediately

The tactics is not obvious at all for me if you don’t know there is tactics available in the position. I am rated 2250 in lichens tactics and was for a time rated over 2300 in 30+ minute games. I have never read a chess book or had any training so I am probably not very representative. Of course when I knew there was tactics available, I saw it too but wood have absolutely missed it in a 3 minutes game but might??? Have got it right in a 10+ minute game. The MC blunder is really a blunder. I saw it immediately within a second and would probably never miss it even in a 5 minute game. It is however understandable that they missed it because it is so obvious that they don’t think the other player would make such a mistake. It is also good to see the previous moves when trying to solve a puzzle. Sometimes it makes the puzzle easier (since you usually move the same piece twice or use a piece that has gotten new possibilities after the previous moves.

I finally found an engine that I can play when a human is NOT around, this is an excellent old engine for Patzer like myself specially during this time of COVi19. I forgot to provide detail I am using the New i9 computer from my brother.

Again, in the position I commented on, Qh7+ wins a rook. If Kg1, then the rook falls on d3. White can both lose the rook and blunder into mate after Rh3: ... Rd1+; Kh2 Rh1+!; Kxh1 Qxh3+ mating; or if white plays Kg3 instead of Kxh1, then ...Qh4+! Rxh4+ gxh4+ is mate.

When solving a tactics problem, look for forcing moves (usually checks or captures).

You were correct the first time. Here was the other draw game that I played versus Sargon
