Hi KnightStalker.
Another reason for the early h3’s is they may be setting a trap!
(you won’t like being reminded of this bit mate, look away now) 😉
(I wonder if they cover anything practical like this in the ‘Fischer Teaches Chess’ book.)
Atomick - KnightStalker47 RHP 2008
1. e4 c5 2. Nf3 d6 3. c3 Nf6 4. h3 {The Atomick waiting move, he has won quite a few games with this.} 4... Nxe4 {OOPS!} 5. Qa4+ {And Black resigned. Although I now of three OTB games where White has gone onto to lose and Atomick himself has lost one after winning the e4 Knight (see below).}
Atomick - Dlevkov RHP 2008
Where we see the waiting for a trap moves 4.h3 and 5.a3.
1. e4 e5 2. Nf3 d6 3. c3 Nf6 4. h3 {In a couple of Atomick players have now played 4...Nxe4 and resigned after 5.Qa4+.} 4... h6 {But not Black, he smells a rat, he is not too sure what happens if he takes the e-pawn so refuses it.} 5. a3 {A classic waiting move again using the e-pawn as bait....this time does Black take it?} 5... Nxe4 {Yes!} 6. Qa4+ Bd7 7. Qxe4 {Another scalp for the Atomick tepee. 1-0.}
Finally, as mentioned in the notes to the first game.
Atomick winning his piece in 5 moves but losing the game.
A wonderful moment coming up at move 18.
Atomick - The Big Fish RHP 2006
1. e4 c5 2. Nf3 d6 3. c3 Nf6 4. h3 {The Atomick trademark.} 4... Nxe4 5. Qa4+ Bd7 6. Qxe4 Bc6 7. Qe3 e5 8. d4 cxd4 9. cxd4 e4 10. d5 Bxd5 11. Bb5+ Bc6 12. Bxc6+ Nxc6 13. Qxe4+ Be7 14. O-O O-O 15. Nc3 Bf6 16. Qg4 Ne5 17. Nxe5 Bxe5 18. Ne4 f5 {Poetic justice. Having won a Knight on e4 Atomick's own Knight on e4 is the reason why he has to give the piece back.} 19. Bg5 {This just made things worse, he had to accept the fact he has returned the piece and play 19.Qf3.} 19... fxg4 20. Bxd8 Raxd8 21. hxg4 Rf4 22. f3 d5 23. Nc5 {OOPS! Instructive moment. White was only concentrating on his Knight Fork on e6. Check all Checks.} 23... Bd4+ 24. Kh2 Bxc5 {White resigned.}
