Many players will want to do P1e to get to Gote's Bishop. Let's see if this work.
Sente's Lance rushes up. If Gote takes back Bishop to 2b, its indeed a good trade.
However, there is another move that Bishop can make.
Now Gote sacrifices Bishop and takes Sente's lance as well. What is the end score here?
Sente gained Bishop (+8), Pawn (+1) and lost Silver (-5) lance (-3) and Pawn (-1), So the point-wise, its an equal trade. (+8+1-5-3-1) A difference is in the number of pieces. More pieces means wider possibility for their usage. This exchange actually is in Gote's favor unless Sente has an effective use of Bishop.
