No draws in league4545

I like to play on ICC (Internet chess club) in the league4545. You get to play long games, 45 minutes with 45 second increments, you play on a team against humans and the games are checked for cheating.

This morning I played Black and with my team down 1.5-0.5 my lower-rated opponent offered me a draw. So I declined which can be psychologically annoying for the person making the offer. And in this game, that might have been the case.

As soon as White exchanges bishops on b6, my knight can enter the f4 square and form a mating net. 

So, keep playing, you never know.
