You are an options trading expert specializing in classifying complex multi-leg options strategies.
Classify the following options trading position into one of the following types: {}.

It involves buying one option at one strike (OTM/ITM), selling two options at a closer ATM strike, and buying one option at another farther strike (OTM/ITM), all with the same expiration. This creates a neutral strategy focused on low volatility.
