  <p>Exactly. There are many opening traps and if you don't know them they are very easy to fall into. For instance it is easy for a beginner playing the Ruy Lopez to fall for a trap which is so old it is called the &quot;Noah's Ark&quot; trap:</p>
  <pre><code>[fen &quot;&quot;]
  
  1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 d6 5. d4  b5 6. Bb3 Nxd4 7. Nxd4 exd4 8. Qxd4?? c5 9. Qd5 Be6 10. Qc6+ Bd7 11. Qd5 c4

Answers.Text: @BlackThorn You're probably not a complete novice if your first thought is to "ignore" the "free pawn". While it seems simple/obvious lots and lots of players have trouble forgoing what appears to be free material(or recovering material), especially in the <10 min games. It may be easier for you, but playing position > "basics" typically isn't (spoken as someone who makes silly mistakes all the time)

Answers.Text: I have never seen this trap before. I found White's P-Q4 unnatural. I've seen other variants of an attack based on the same principle of potentially trapping the bishop but I used to have a thesis of you can't actually win the bishop this way. It usually ends up on R2 with a pawn on R3 blocking any chance of winning it.

Answers.Text: Yeah this is pretty interesting. First, instead of Qxd4, White should probably play something like a4 (attacks pawn on b5 to get time), but already against principles. 
  Instead of 6.d4, a viable move is 0-0 (but that might give up bishop after b5-Na5) or Bxc6+ - and here you have to know why White waits with the capture (so black has to take with the b-pawn instead of d-pawn).

It takes a deep tactical analysis to show that if 3.Nxe5 fe5 4.Qh5+ g6 5.Qxe5+ Qe7 6.Qxh8 Nf6 then Black does not have a significant counter-attack and also that White can extricate the Q from the corner before it gets trapped.

Answers.Text: I've been re-learning for almost a year now (played minimally as a kid), and I've found that playing 5 or 10min games rapidly has been a much more fun way to learn openings/traps than studying a book. I don't know the "proper names" of anything, but fall for opening traps less and less. As you say "Falling for traps is a great way to learn about them, very memorable" - rarely fall for the same twice, where I'm sure that even if I'd read about it 10 times, I'd probably still fall for it once anyway.

  Exactly. There are many opening traps and if you don't know them they are very easy to fall into. For instance it is easy for a beginner playing the Ruy Lopez to fall for a trap which is so old it is called the "Noah's Ark" trap:
