Whinging about cheats, eh Anders? Can't accept that you lost?

Seriously though. If a player like frolind doubles, you should never redouble on your next go unless he's rolled an awful, terrible, stinking number.

What frolind said about "gifts" is very true. Your second redouble was immediately after accepting a double that should have been dropped as if it were a hot rivet. In each case you redoubled when frolind's post-double roll had sent a man of yours to the bar. In the second case that meant two on the bar and with a 4-point table to get back into and builders at the ready!
