(Somewhat) Intriguing Positions Edition 2

Jun 24, 2015, 7:59 AM |

I am currently playing a correspondence game in which I encountered the following position after 20... Ra4 (I was playing black against a lower-rated player).

The idea here was to take on c4 on the next move, but I realised that my rook would have been trapped after b3, so instead, I planned on retreating my rook back to a7 on the next move. I was expecting b3 to be played right away, but instead, my opponent played the move Qc2, attacking the rook, which I retreated anyways, wasting two moves.
I don't know if one could call this position particularly interesting, but anyways, I thought it would show one how to avoid traps amidst muddled-up pawn structures.
