In this video lesson, GM Igor Smirnov shares with you one of the trickiest chess openings for Black, which is universal as it works against both 1.e4 and 1.d4 by White.

It’s called the O’Sullivan Gambit from the Alekhine’s Defense which happens after the first moves: 1.e4 Nf6 2.e5 Nd5 3.d4 b5. It can also be transposed if White plays 1.d4 and then 1…b5 2.e4 Nf6 3.e5 Nd5.

This gambit is so tricky that White loses in just 6-8 moves in the most common variations. It sets a trap almost every move and even top-rated players fall for these traps; yes, it works even against 2500+ players!

  1. Love your vids, watch every one when I get the notification, always good stuff. Bought the course as well, it's great!

  2. Ur opening never happened to me once in 15 black games even tho I try my fuckin best to transpose the position into it so yea pretty useless

  3. Happy Birthday, you are the age of my eldest daughter

  4. Pawn could take eponsont and still get the check

  5. nice defense: unusual, deceptive (looks like alekhine's def at first) and easy to remember.

  6. I hardly ever (1 or 2 in 100) see a two pawn move opening by white (playing ten minute games at 1000). So sadly, I doubt I will ever be able to use this. Thanks anyway.

  7. I just played it, and white did play c4 anyway, and I lost badly.

  8. I paused the video for about two minutes to see where my cat was!!πŸ˜„

  9. At 3:04 what if white plays nighta3 to attack the black queens as well ?

  10. Im so glad i found your channel. I play very similarly to your style (albeit many ELO lower πŸ˜‚) and even though your channel deserves to be bigger, its not yet so all of these tactics become successful for me!

  11. I am thinking white will play knight c3 since there is no defender for black knight which kinda invalidates pawn b5?…not been through the entire video yet

  12. Igor your voice will sound better and more professional if you absorb some of the reverb. Maybe a carpet or hang a curtain.

  13. I bet your cat would totally approve of my "Zeller Ice Queen" (in the blackmar diemer gambit) as the "main line" is about 3 points bad for white, but is a rare line with around 70% chances in every other line. an online troll griped that it's "unsound", parroting the old GM talking point, but any time you're winning 70% or more of your games, the word unsound doesn't apply. gambiteers like risk and i'm so glad i stumbled on this as I was having a hard time trying to find a repertoire against 1.d4 to go with the albin (few gambits) and with indian/benko, but THIS, like the rousseau which this kings gambiteer so wants to get rid of the scandinavian for, looks like just what i need to stop effing stonewalling. i hate pawns in the way even if the stonewall is very playable if you don't mind 50+ move games.

    thanks for sharing, i'm cobbling a book out of this video and lichess right now. the carnage in the MAIN LINES is awesome! i'll put up with 1 in 20 painful losing games for 19 fun ones any day!

    BTW i'm NEVER playing the alekhine! i hate hypermodern everything! this looks better as a 1.d4 repertoire that can't be side stepped

  14. Many Happy Returns.. Thanks for sharing all your Chess knowledge.. this means a lot to us as beginners as well as advanced players.. Stay blessed πŸ™πŸ» Love from Indonesia

  15. No Shame in My Game! Keep Crushing the overzealous white.πŸ’―πŸ”¨β™Ÿβ™Ÿβ™Ÿ

  16. Nah wait wut, this is too good . I will share this chhannel with all of my friends who play chess damn this is so good lol I won 3matches with blackπŸ’€

  18. Happy bthday Igor, I wish U all the best & more and more happy years of life & chess!

  19. Stockfish says 76% is the optimal discount on your courses

  20. Hey, happy birthday, bro!!! I am new to Chess. Guess what. Within a month, your strategies and knowledge has helped me a lot to win some of my friends who have been playing it for years! I can't thank you enough for your well-explained videos. They're totally precious. Wishing you the best birthday ever! Cheers to playing Chess!🍻

  21. This won't work any longer considering that now everyone is aware about this πŸ₯²

    Also, happy birthday sir!

  22. It's a cool trap but I feel even weak players can sense it's a bad move (the bishop takes the free pawn). Common knowledge that your bishop will just get kicked next move (at minimum), and potential for complications early. Maybe blitz chess this could be a common mistake tho.

  23. I've been using Russeau for quite a while and it works somewhat well, although there are some nasty downsides. Might I try this one? It seems that white is going to knight out very often instead of pushing forward…

  24. What if they play knight to C3 and block the check as well as protect the bishop?

  25. Many more happy returns of the day. God bless you πŸ’πŸ’πŸ’

  26. I recommend you to use this gambit in a OPEN Classical tournament Igor.

  27. Happy birthday. Long supporter of chess and #1 GM commenter.
