Would be intersting to know if queen sacrifce was sound or weather i just got lucky. Amazing how opponent did not have a single developed peice and even when i did not check him, there seemed to be nothing he could do
Queen sacrifce in opening to bring king out and finally mate!
Sort:
Beautiful sacrifice, but black blundered a lot and sjould have won. In standard chess, this sacifice would have been punished hard, but in a blitz match it might work (as here).
My computer (engine Stockfish) gave you a an avantage of +0.16 (depth 24) if you played 7. h3. Instead you played 7. Nxg5 and your advantage dropped to around -4 (depth 24) if black captured your queen (as he did).
After 8. Bxf7 the evaluaion was still between -3 and -4, but when black played 8... Ke7. The computer found this position totally even; +0.00 (depth 28). However, if black played 8... Kd7 instead, he would still have a severe advantage.
From then on, you both blundered a lot ...
Besides the fact that this sacrifice is refutable, it looks cool. Thanks for sharing.
yeah, that was nice, but black did blunder a lot, here is another called Legal's mate;
you like it huh?!
Interesting, nice moves
Here is a cool puzzle I made up based off the OP's game.
In the final position, white can continue on for a while playing for a win (thats a hint in itself).
I love making puzzles.
Great game -- very interesting sacrifice.
Thanks for your comments. Really interesting what waffledestroyer shows that if I had moved 7...ke5 and opp had taken queen then could have got quick decisive mate. I put through computer analysis and it said 7..h3 was best, I guess as opponent could just take knight instead of queen.
The analysis seemed to tell me I blundered on almost every move but one that I completely don't understand is 19...bc3 which apparently was a blunder and 19...bxd5 was best chasing pointless material when I was so far down I would obv loose. After my move 19...bc3 I can't see anyway my opp could avoid mate so would love to know why this was a blunder.
Nice puzzle thanks :-)

Who needs an engine for that.
Kd7, avoiding Nd5+, is an obvious win. White has very little compensation for the queen.
After Nd5+ it is also relatively obvious that black cannot avoid a perpetual (Be6+ Ke8 Bf7+ Kd7 or Nb4+ Kb6 Nd5+ Kc6 (Ka6 Nb4+). Then he proceeds to go even further forward to attempt to avoid this, and reaches a lost position.
About the Bc3 blunder, what evaluation does the analysis give? In completely won or completely lost positions a move that goes from +11 to +9 in the computers eyes is usually considered a blunder. Also, what line does it give?
For example, I can calculate this far, I'm not sure if my calculation is accurate, but it shows why Nd5+ is necessary. No engines needed.

how is a sacrifice beautiful if its refutable?
Maybe Stockfish'll know that one.
Wow, that's fantastic. I've been looking through this game for a while admiring the play.
Hi shepi, this is the line that the chess.com analysis gives
19. Bxd5 Qxd5 20. exd5 Kxa2 21. Ne6 f3 22. gxf3 Na6 23. c6 ) ( 19. Bc3 Kxa2 20. Nf7 Qh4 21. Nxh8 Nf6 22. e5 Qh5+ ) recapturing opp queen instead of going for mate. It says analysis strength is 2000 but that HAS to be wrong as following this line is a certain loss.
