Is it worth to lose your pair of bishop over a pawn advantage?


For exemple, your opponwnt has 2 knights and you two bishops. The bk

Still, you deserve some sort of punishment. Think up one and let us know how it turns out.
You know, the value depends. You neglect to specify the position other than "wide open." There are cases where one is better, other cases where the other is better. Personally, I prefer the pawn in most positions. Knights are tricky as heck. Chigorin knew what he was on about.

One of the reasons Bishops are generally more valuable than Knights is that it's usually easier to trade a Bishop for a Knight than it is to trade a Knight for a Bishop. So if you have the Bishop pair you should always look for opportunities to trade one or both of your Bishops in order to gain some other kind of advantage, such as winning a pawn. So yes, you should usually give up your Bishop pair if you can win a clean pawn.

If everything else is equal, then taking the extra material should be a no brainer.
But of course things are rarely otherwise equal, so you have to weigh piece activity.
Piece activity, not fanciful ideas like having the bishop pair for its own sake.

+1 situations differ greatly, but this is the general guideline here; win material if you safely can. As another guideline, lots of players consider the Bishop pair to be worth about "half a pawn" in value. If you get the chance to win even a pawn successfully, I'd probably take it (even at the cost of giving up the Bishop pair).

Typically this would depend on the position. Closed versus open positions. In a closed position, knights are generally better than bishops and vice versa with the closed positions. So always look at the position, determine if it is open or closed then you can decide whether the pawn is worth it. DEPENDING on the position, a pawn will probably justify losing the bishop pair.
