there are tricks to getting in in that situation. it all depends on where your base is and what pieces you ahve left.. if you ahve less pieces than you have moves..e.g. you have only two 5s and your playing the fast version that means that you have to move both of those pieces. than i can work my way around you b/c your forced to move. so ill sacrifice one piece to get to your base...one will get through. but getting the sappers is another challenge. no experienced player will let them go that easily so taht situation will almost never happen!
