Yes, maybe the exchange isn't the exchange it appears to be. We aren't exchanging the Russians from big places as DC or places more important as it seems but from Washington State isn't it? Hold on..what if its an exchange of mutual interest? We are trading information needed that both countries want. Our informants in exchange for their informants.
In general, one makes an even trade of pieces in order to prevent the enemy piece from becoming too active or to give you time to accomplish another task. Other even trades turn out to be far from even, in that an exchange leads to a very clear positional, tactical, or even defensive gain. In this lesson, a possible trade may ...not lead to something concrete. It's up to you to judge whether or not this is the case...chess
Wow. Now there’s another layer!
