1. Hand grab gambit
Pick up the opponents pawn/knight/bishop/rook/queen while they are not looking and remove it from the playing grounds as sneakily as possible. Also similar to the clock gambit.
2. 3 time repetition of stalemate claim
You can claim a stalemate if the TD does not know what it is by asking for it 3 times.
3. Clock bang gambit
If you are running low on time you can quickly tap the side of the clock and it will loosen the battery thus the TD cannot determine official times so both sides get more time.
